Overview of Oral Surgery, Extraction of Roots

A tooth root left behind after a tooth breaks is a common issue. This can happen for many reasons. These tooth roots can make it more complex to remove a tooth, and often need to be handled in special ways, different from the normal tooth removal process. This piece will guide you through several surgical and non-surgical points to consider, tools, and methods that can be of help in removing these remaining tooth roots. This approach is aimed at making the process more efficient, making sure patients have improved results, and reducing possible complications from the procedure.

Anatomy and Physiology of Oral Surgery, Extraction of Roots

The root of a tooth is a special part that helps the tooth function when we chew our food. It gives the tooth a sturdy support in the jaw bone and balances the pressures from biting and grinding. The root also allows the tooth to have a blood supply and feeling because it connects to the nerves and blood vessels in the jaws. What’s very important to note is that the size, shape, length, and number of roots can differ a lot between teeth. This can affect how hard it is for a dentist or surgeon to remove a tooth, so understanding these differences is crucial for them.

Tooth development happens through a process involving different cells. First, a ‘dental lamina’ is formed, and various cells start to deposit organic tissue. Enamel, a very hard tissue, forms the outer layer of the tooth’s crown (the shiny part we can see in the mouth). This enamel is deposited by cells known as ameloblasts. Just below the enamel is another hard tissue called dentin, which is made by cells called odontoblasts. Layer by layer, these cells build up the crown of the tooth. The crown finishes where the enamel ends and the root of the tooth begins.

The root of the tooth starts to form after the crown is complete. A structure called Hertwig’s epithelial root sheath (or HERS) guides the root formation. The root’s outer layer is a mineralized tissue called cementum, which connects the root to the jaw bone with the help of the periodontal ligament. Recent research suggests that certain signaling pathways in the body are involved in guiding the formation and shapes of tooth roots, but further understanding is still needed.

The roots of teeth tend to have common features among most people. In the upper jaw (or maxilla), the front teeth (incisors and canines) usually have one root each. The first premolar tooth slightly further back usually has a long main part (or trunk) of the root, which then splits into two smaller roots. However, sometimes this tooth only has one root. The first molar tooth at the back of the mouth usually has three roots – two on the side towards the cheeks (buccal roots) and one bigger one on the inner side (palatal root). These roots often lean back into the mouth (distal inclination) and can curve.
The second molar has less curve, and the very back tooth (the third molar) often has shorter roots that are fused together.

In the lower jaw (or mandible), the front teeth (incisors and canines) usually have one root each, with the canine tooth occasionally having two roots. The premolar teeth and the molar teeth typically have single roots, but again, there can be some variation. The molar teeth usually have two roots that lean back in the mouth, with the first molar having longer roots than the second. Lastly, the third molar in the lower jaw also tends to have two roots, often aligned side-by-side, slightly shorter and more tapered compared to other molars.

Why do People Need Oral Surgery, Extraction of Roots

Dental roots that remain beneath the gums can sometimes cause issues and need to be removed. There are different reasons why this might be necessary, which include:

  • If there’s an infection, either sudden or ongoing
  • If the visible part of the tooth (crown) is broken or fractured
  • If you need a dental implant to replace a missing or damaged tooth
  • If you’re experiencing toothache or discomfort
  • If the tooth root is cracked or broken
  • If you have gum disease
  • If you have tooth decay (cavities)
  • If you have other diseases of the mouth or gums
  • If you need a denture or a crown fitted
  • To protect the health of teeth and structures around it
  • If it bothers you how the area looks

Some people might need to have these roots removed as a preventive measure, even if they aren’t having any symptoms. This might be suggested if it will be difficult or impossible to get dental care in the future. For instance, people going away for military service might have this done. Similarly, if someone will be having radiation treatment for head or neck cancer, or needs to take certain medicines that could harm the jawbone, removing these roots may also be considered as a precaution.

The dentist or oral surgeon should discuss with the patient all the relevant reasons, risks, and benefits of this procedure. This is necessary so the patient fully understands the procedure and can make an informed decision about their treatment.

When a Person Should Avoid Oral Surgery, Extraction of Roots

In certain situations, removing a tooth root may not necessarily be beneficial and might carry more risks. In some cases, it may be better to leave behind parts of the tooth root for a while, especially just before inserting a dental implant. Keeping these root parts can help maintain the bony socket that holds the tooth, making it easier to place an implant later.

After weighing the pros and cons, the dentist can decide if removing the root is necessary or, for some reasons, it should be left behind. One reason to leave a root fragment is if there’s a high chance of harming neighboring teeth or critical structures, like the nerve that supplies sensation to the lower jaw, known as the inferior alveolar nerve.

There are also some potential risks that might stop a dentist from removing a root. For example, there’s a chance the root pieces might wrongly move into nearby areas like the upper jawbone sinus, or cause the supporting bone to break. Making an unintended hole between the mouth and sinus might also stop a dentist from removing the root.

Another factor to consider is that keeping these root pieces can help maintain the bony socket. This strategy, often called root submergence, can be useful when thinking about future options for artificial teeth.

In some circumstances, if a root breaks during a surgical procedure involving a healthy tooth center with appropriate wound management, it’s often entirely fine to leave the root to heal indefinitely. Lastly, it essential to consider the patient’s wishes when deciding treatment plans. If a patient chooses not to go under treatment, then it becomes a valid reason not to remove the root.

Equipment used for Oral Surgery, Extraction of Roots

The removal of teeth roots requires several tools often used in regular tooth extractions. Here are some typical tools used:

* Elevators: These are used to loosen the tooth from its socket.
* Luxators: These are similar to elevators but thinner, used to cut periodontal ligaments and loosen teeth.
* Forceps: These are like pliers used for grabbing and pulling out teeth.
* Root tip picks: These are tools used to remove the root tips that might remain in the socket after tooth extraction.
* Retractors: These are used to hold the mouth open and tissues away for better view.
* Curets: These tools scrape and clean the surfaces of teeth or bones.
* Dental explorers: These find cavities or assess the level of tooth decay.
* Dental mirrors: These help the dentist see hard-to-view areas in the mouth.
* Scissors: These cut tissues.
* Scalpels: These are used for surgical cutting.
* Hemostats: These clamp blood vessels to stop bleeding.
* Periodontal Probes: These measure gum pockets.
* Rongeurs: These cut and trim bones.
* Bone files: These smooth down the bone.
* Local anesthetic needles and syringes: These inject numbing medication so you won’t feel pain.
* Irrigation needles and syringes: These clean out the area with fluids.
* Local anesthetic: This is the medication that numbs your mouth.
* Sterile gauze: This is used to soak up blood and keep the area clean.
* Sutures: These hold tissues together as they heal.
* Surgical handpiece and surgical bur: These tools are used for high-precision cutting and drilling.
* Sterile saline: This is salt water used to clean wounds.
* Sterile water: This is used for cleaning and irrigation.
* Bite block: This keeps the mouth open during surgery.

Good lighting is key in dental surgery because it helps the dentist see clearly when removing roots. The dental operation room and the area of surgery should always be well-lit. To see even better, many dentists often wear specialized glasses that magnify what they’re looking at, and sometimes, lights attached to their heads. The surgical team always wears protective clothing for safety. They also ensure the patient is properly prepared for the surgery.

Over time, dentists and surgeons have added more tools to their inventory to better remove tooth roots. The tools they use depend on their preferred way of extracting these roots. Some use file tools meant for root canal treatments, thin tools that separate teeth from gums, systems that pull roots vertically, and special surgical instruments that work with sound waves.

The right tools help the dentist predict and ensure success in oral surgery. This is especially true when removing roots that have remained in the mouth after tooth removal.

Who is needed to perform Oral Surgery, Extraction of Roots?

The team involved in a surgical procedure can change depending on the rules of the state and how much anesthesia (medication to make you feel no pain) is needed. At least, one dentist or surgeon and one assistant with surgical experience are required if the procedure requires local anesthesia (a type of medication that numbs a specific part of the body). During the operation, the assistant helps the surgeon by handling tools and managing the surgical site.

If the surgery requires sedation (medication to make you sleepy) or general anesthesia (medication to make you unconscious), more medical personnel may be needed. The roles of each team member may change depending on the type of anesthesia used. For example, an assistant trained in monitoring anesthesia may focus on ensuring your breathing is safe during the operation and will inform the team of any significant changes in your heartbeat, blood pressure, or general condition.

In outpatient surgeries, meaning surgeries where you don’t have to stay in the hospital, it’s necessary to have a licensed medical professional who is trained to administer anesthesia. This could be a specialist nurse known as a certified registered nurse anesthetist (CRNA), anesthesiologist, or dentist. Additionally, other staff members will help with important tasks such as confirming that you understand and agree to the procedure (informed consent), updating your medical history, noting any allergies, and doing all required checks before the procedure. The smooth operation of the surgery team contributes to your safety and the efficiency of the surgical process.

Preparing for Oral Surgery, Extraction of Roots

Before starting any surgical procedure, the doctor needs to understand your health completely. This means looking at your overall physical condition and going through your previous medical records, as well as any medication you’re currently taking. This way, the doctor is fully aware of your state of health and can take steps to prevent any complications during and after the operation. This thorough understanding of your medical history also helps the doctor to decide the best approach for your recovery after the operation, including managing any potential pain and helping the healing process of the operated area.

Part of the pre-operative evaluation involves a detailed check of the area inside your mouth where the surgery is to take place. The doctor will also look at x-ray reports to understand the health of the area surrounding the surgery site, check for tooth decay at the site, understand the extent of movement of any tooth segment, and also evaluate the condition of teeth adjacent to the surgical site. This pre-check is crucial in helping the doctor decide what kind of surgical tools to use and what kind of blood flow control agents will be required during the surgery.

X-ray evaluation is very important when dealing with leftover tooth roots. Modern technology such as 3D imaging aids (known as Cone-Beam Computed Tomography, or CBCT), helps in getting a detailed understanding of the depth, exact location, size, curvature, and proximity of any leftover tooth roots to close-by important anatomical structures like the upper part of the mouth (maxillary sinus), and lower jaw nerve (inferior alveolar nerve). Traditional 2D X-rays also play a key part initially in the evaluation of leftover tooth roots. Not every tooth extraction process (exodontia) needs a 3D imaging evaluation, but when there are potential risks of unintentionally causing harm during an operation (known as iatrogenic damage), these tools are highly beneficial.

The pre-operation check not only helps the surgeon make an accurate diagnosis but also choose the correct method of treatment. Medical professionals need to make decisions based on proven medical evidence and best practices when dealing with leftover tooth roots. Lastly, a surgeon needs to be sure they have the required knowledge and tools to safely and effectively carry out the operation. You should know that it’s perfectly okay for a doctor to transfer the patient to a more specialized healthcare provider or a provider with better expertise in treating specific health conditions.

How is Oral Surgery, Extraction of Roots performed

Before starting any dental surgery, it’s important that the patient feel comfortable and give their permission for the operation. They are also given a local anesthetic to numb the area and prevent pain throughout the procedure. It is always the aim of the dentist or surgeon to avoid damaging the surrounding gums, soft tissue, and bone when removing a tooth. However, some level of injury may be unavoidable, and it can lead to loss of some of the bone surrounding the tooth.

In dentistry, different methods exist for removing the root parts of a tooth such as:

Closed Surgical Technique: The dentist tries to remove the root part of the tooth from the top of the socket without having to cut and fold back the gum to see what they’re doing. To do this, they use dental elevators which function based on three simple principles of physics: using it as a wheel, a lever, or a wedge. As a wheel, it makes a circle between the elevator tip and the body of the root to lift the root out. As a lever, it uses a specific point between the top edge of the socket and the root as a pivot point to apply force. If the current pivot point isn’t sufficient, nearby bone may need to be removed to create a better one. Lastly, as a wedge, the dental elevator is placed parallel to the root, splitting the root and the supporting bone, allowing for the root to be gradually lifted out. This technique requires expert handling to avoid harming surrounding tissues.

Piezosurgery: This advanced tooth extraction method uses ultrasonic vibrations to make precision cuts for the removal of the root. It allows for minimum bone removal and doesn’t harm the surrounding tissues. It’s especially worth mentioning as traditional drilling methods can unintentionally damage both hard and soft tissues.

Open Surgical Technique: This method involves folding back a sector of the gum to see and gain better access to the root. This technique often requires the removal of some of the outer layer of the bone to reach the root(s). This method is often only used when other, less invasive techniques have failed or are not options.

Using Rotary Drill: With the invention of the surgical drilling tool, it’s much easier to switch from simple tooth extraction to surgical extraction. The drill shortens the operation time by allowing access to previously inaccessible points of the tooth.

Endodontic File Technique: This root extraction method uses a special tool called an endodontic file. The file is inserted into the root from the top side of the tooth and is pushed downward until it makes firm contact within the canal. The success of this technique depends on the size of the root part to be removed and the condition of the tooth’s connective tissues. However, inexperienced use of this technique can lead to the tool breaking inside the tooth, which may complicate the extraction.

The dentist or surgeon will use the technique that they think will work best for your specific case, and as they gain more experience, they can more effectively ensure your safety and comfort during the surgery.

Possible Complications of Oral Surgery, Extraction of Roots

It’s crucial to plan properly and use the right method when performing dental surgery. However, even with the best preparation and care, unwanted issues can sometimes occur during or after the tooth removal process. These problems aren’t limited to more complex cases; even straightforward tooth extractions can lead to:

* Pain
* Bleeding
* Infections
* Bone or jaw fractures
* Bone infection (osteomyelitis)
* Bone death (osteonecrosis)
* Inflammation of the tooth socket (alveolar osteitis)
* Dental implant failures
* Poor wound healing
* Burns

A key factor to consider when removing any tooth is how close the tooth roots are to certain important areas in your body like the floor of the maxillary sinus (a cavity located within the upper jaw bone that opens into the nasal cavity), or the inferior alveolar nerve, which provides sensation to the lower teeth and jaw.
Unintentionally pushing teeth or tooth fragments into these nearby areas during surgery is an uncommon but significant complication that can happen due to lack of proper examination before surgery, too much force during extraction, poor visibility of the site or insufficient retraction of the gum and bone covering (the mucoperiosteal flap).

The roots of back upper teeth often touch or even penetrate the floor of the maxillary sinus. In fact, more than half of upper molar teeth show this kind of protrusion. Other areas where tooth displacement can occur are the submandibular (under the jaw), sublingual (beneath the tongue), buccal (cheek area), and pterygomandibular (near the lower jaw) spaces.

In rare cases, upper back teeth can even be pushed as far back as the infratemporal fossa, a space at the side of your skull. This could often need different surgical techniques for removal. Displacing and even retrieving tooth roots from any anatomical area in the face or neck can potentially increase the patient’s discomfort or risk. That’s why doctors recommend only trying to retrieve a tooth or root if it’s fully visible and easy to hold onto at the time it gets displaced. If it’s not, then the best course of action is to immediately refer the patient to a specialist for assessment and treatment.
Injury to the nerves from tooth or tooth root removal, specifically with lower third molars (or wisdom teeth), is another rare but serious complication. For some patients, the roots of the wisdom tooth can be in direct contact with the mandibular canal, carrying the inferior alveolar nerve. Research has found that the frequency of such direct contact is as high as 7.1%.

Results from another study suggest that the canal is usually located beneath the root of the third molar (in 77% of cases). However, it can be found on either side – the tongue side in 11.8% of cases and the cheek side in 8.9%. Rarely, in about 0.7% of the time, the canal could even pass between the roots.
All this emphasizes the point that although complications from tooth root extractions are uncommon, they can happen swiftly and without much warning. Hence, it is important for the surgeon to evaluate the potential risks before proceeding with the surgery. Careful planning and using the appropriate surgical techniques can help to prevent most of these undesirable outcomes.

What Else Should I Know About Oral Surgery, Extraction of Roots?

It’s not uncommon for small pieces of tooth roots to be left behind after a tooth extraction. Dentists and surgeons who regularly perform tooth extractions usually have a strategy for removing these lingering root fragments. Until recently, there weren’t any official guidelines published on how to best remove these root fragments.

As the field of dentistry continues to advance, general dentists are performing more tooth extractions and surgeries than ever before. Most dentists and dental specialists know, removing teeth can be a challenging task. Sometimes the process doesn’t go as smoothly as planned, and the dentist may need to switch to a more complicated surgical extraction.

Having leftover roots can make the procedure longer and more stressful for both the patient and the dentist. To prevent harm and to ensure the best outcome for the patient, it’s important that the dentist performing the extraction has the right knowledge, skills, and confidence. They should be familiar with the latest surgical techniques to deal with unexpected situations like leftover root fragments.

Frequently asked questions

1. What are the reasons for removing the tooth roots? 2. What are the risks and benefits of removing the tooth roots? 3. What tools and techniques will be used during the extraction? 4. What is the expected recovery process after the surgery? 5. What are the potential complications or side effects of the surgery?

Oral surgery involving the extraction of roots can have various effects on an individual. The size, shape, length, and number of roots can differ between teeth, which can make the extraction process more challenging for a dentist or surgeon. Understanding these differences is crucial for them to ensure a successful extraction. Additionally, the roots of teeth in different areas of the mouth, such as the upper jaw and lower jaw, can have specific characteristics and variations that may impact the extraction procedure.

There are several reasons why someone may need oral surgery for the extraction of roots. One reason is if there is a need to remove a tooth root before inserting a dental implant. Leaving behind parts of the tooth root can help maintain the bony socket that holds the tooth, making it easier to place an implant later. Another reason is if there is a high chance of harming neighboring teeth or critical structures, such as the nerve that supplies sensation to the lower jaw. In such cases, it may be better to leave a root fragment behind to avoid potential damage. There are also potential risks associated with removing a root, such as the root pieces moving into nearby areas or causing the supporting bone to break. If there is a risk of these complications, the dentist may choose to leave the root behind. Additionally, keeping root pieces can help maintain the bony socket and provide future options for artificial teeth. This strategy, known as root submergence, can be beneficial in certain circumstances. Ultimately, the decision to remove a root or leave it behind depends on the dentist's assessment of the situation, weighing the pros and cons, and considering the patient's wishes.

One should not get the oral surgery extraction of roots if there is a high chance of harming neighboring teeth or critical structures, such as the nerve that supplies sensation to the lower jaw. Additionally, there are potential risks such as the root pieces moving into nearby areas or causing the supporting bone to break.

To prepare for oral surgery and the extraction of roots, it is important to have a thorough understanding of your medical history and overall physical condition. The dentist or surgeon will evaluate the area inside your mouth where the surgery will take place and may use x-ray reports to assess the health of the surrounding area. Good lighting is essential during the surgery, and the surgical team will wear protective clothing.

The complications of oral surgery, specifically extraction of roots, can include pain, bleeding, infections, bone or jaw fractures, bone infection (osteomyelitis), bone death (osteonecrosis), inflammation of the tooth socket (alveolar osteitis), dental implant failures, poor wound healing, and burns. Additionally, there is a risk of pushing teeth or tooth fragments into nearby areas such as the maxillary sinus or inferior alveolar nerve during surgery. This can result in discomfort or increased risk for the patient. Injury to the nerves, specifically the inferior alveolar nerve, can also occur during the removal of lower third molars (wisdom teeth). It is important for the surgeon to evaluate potential risks and use appropriate surgical techniques to prevent these complications.

Symptoms that require oral surgery, extraction of roots include infection, broken or fractured visible part of the tooth, toothache or discomfort, cracked or broken tooth root, gum disease, tooth decay, other diseases of the mouth or gums, need for a denture or crown, and the need to protect the health of teeth and structures around it. Additionally, some people may need to have these roots removed as a preventive measure, even if they aren't experiencing any symptoms.

The safety of oral surgery, specifically the extraction of roots, during pregnancy depends on several factors. It is generally recommended to avoid elective dental procedures during the first trimester and last half of the third trimester. However, if the procedure is necessary to alleviate pain, infection, or other dental issues that may affect the health of the mother or baby, it can be performed with precautions. Before proceeding with any dental procedure during pregnancy, it is important to consult with both the dentist and obstetrician to assess the risks and benefits. The dentist will consider the stage of pregnancy, the complexity of the procedure, and any potential risks to the mother and baby. Local anesthesia with lidocaine is commonly used during dental procedures and is generally considered safe during pregnancy. However, the use of certain medications, such as sedatives or general anesthesia, may be limited or avoided during pregnancy. It is important to note that dental infections and untreated dental problems can potentially have negative effects on pregnancy outcomes. Therefore, if there is a dental issue that requires treatment, it is important to address it to maintain oral health and overall well-being. Overall, the safety of oral surgery, including the extraction of roots, during pregnancy depends on the specific circumstances and should be discussed with healthcare professionals to make an informed decision.
