What is Alveolar Osteitis (Dry Socket)?
“Dry socket,” also known as Alveolar osteitis (AO), is a common issue that can occur after a tooth is pulled out. The frequency of this happening varies, with some reports saying it happens between 0.5% and 5% of the time, while some studies have recorded it as high as 68%.
Dry socket is marked by a prolonged pain, ranging from moderate to severe, where the tooth was taken out. This often leads to multiple visits to the dentist for treatment and relief from the discomfort. It’s commonly believed to be caused by what’s known as the fibrinolytic theory. Basically, the socket where the tooth was removed showcases exposed bone due to the absence or loss of a blood clot that usually forms after a tooth is extracted.
Even though dry socket is a routine complication encountered, there’s still a level of uncertainty about how it develops. This has led to several suggestions for ways to prevent and manage it, but at present, there is no agreed-upon approach that is backed by scientific evidence. This piece touched on the risk factors and suggested ways to treat dry socket.
What Causes Alveolar Osteitis (Dry Socket)?
Alveolar osteitis, also known as dry socket, is a condition we’ve known about for a while. But, the specifics of what causes it are not entirely clear yet. It often happens when a protective blood clot that forms after a tooth extraction breaks down too soon, leaving the bone underneath exposed.
In 1973, Birn suggested that alveolar osteitis might develop either because there’s no blood clot to begin with, or because the clot that does form breaks down almost as soon as it’s created. While we’re not sure what causes the breakdown of the clot, evidence pointing to biological or unnatural substances has been put forth. Interestingly, most of these substances accelerate the blood clot’s breakdown, leading to what we know as fibrinolysis.
After a tooth is extracted, the body reacts almost exactly as it would to any other tissue damage. The inflammation in the socket is controlled by both pro-inflammatory and anti-inflammatory signals. Although studies have mainly focused on a molecule called IL-6, which contributes to bone formation and breakdown, it could also be responsible for breaking down the blood clot in dry socket cases.
Other studies have suggested looking at signals like the tumor necrosis factor-alpha (TNF-a), osteocalcin, and runt-related transcription factor 2. They believe these signals might better explain how alveolar osteitis develops.
Bacteria in the mouth has also been investigated for its role in this condition. Interestingly, the types of bacteria found in people with dry socket were different from those in people without complications following tooth extraction. For example, bacteria like Treponema denticola, a known gum disease-causing bacteria, has been cited as a possible cause of dry socket. However, in order to confirm the role bacteria plays in dry socket, these bacteria should not result in swelling, pus, or redness, and they ought to be present at the site of extraction. Poor oral hygiene is usually an ideal condition for such bacteria. Notably though, dry socket is not classified as a true infection, since these bacteria is limited to the bone’s surface.
Risk Factors and Frequency for Alveolar Osteitis (Dry Socket)
Alveolar osteitis, a condition that affects the jaw, has an incidence rate that varies widely according to different studies, ranging from 0.5% to 68%. Bigger studies have shown that the common incidence is often less than 5%. On average, about 30% of lower jaw third molar extractions result in alveolar osteitis.
The third molar area of the lower jaw is more likely to develop alveolar osteitis than any other dental extraction site. This might seem surprising, as this condition is often believed to be caused by a lack of blood supply, and these molars tend to have more blood flow than front teeth. This makes alveolar osteitis less common in the upper jaw.
While there are conflicting studies, many have determined that age and female gender could increase the chance of experiencing alveolar osteitis. However, it’s important to note that this condition is prevalent worldwide and isn’t influenced by one’s ethnicity.
Women taking oral contraceptive pills or those in the middle of their menstrual cycles have shown a statistically significant increased risk of developing this condition. The cause seems to be lowered plasminogen activator inhibitor and increased plasminogen, which result in increased fibrinolysis, a process that prevents blood clots.
There are several other factors that could contribute to the development of alveolar osteitis, including:
- Tobacco use
- Poor oral hygiene
- Lack of operator experience
- Design of the flap created during extraction
- Difficulty of the extraction.
These risk factors have been supported by numerous studies, but the role of most others hasn’t been clearly demonstrated.
Signs and Symptoms of Alveolar Osteitis (Dry Socket)
Alveolar osteitis, also known as dry socket, is a problem that can happen after a tooth is removed. The main symptom is a pain that gets worse near the spot where the tooth was removed. This pain often starts between one and five days after the tooth is pulled. It’s important to note, regular painkillers won’t ease this type of pain. Bad breath is also a common sign of dry socket.
When a doctor checks the patient, they won’t usually see anything abnormal. Expected changes after a tooth removal, like redness and swelling, will be there. But there shouldn’t be clear signs of infection like pus. Sometimes, there may be mild fever or swollen glands.
Generally, patients do not show fever or any big changes in their vital signs. What does happen is that the blood clot that normally forms after tooth extraction breaks down prematurely or dissolves. This leaves the bone exposed in the socket, which is a common sign of dry socket. However, this can be hard to see during a check-up.

- Pain starts between one and five days after extraction
- Bad breath
- Redness and swelling
- Possible mild fever or swollen glands
- Blood clot dissolves or breaks down prematurely, leaving bone exposed in the socket
Testing for Alveolar Osteitis (Dry Socket)
If you’re feeling more intense pain a few days after having a tooth pulled, it could be a sign of a condition called alveolar osteitis. The key signs of this condition are increased pain and the absence of a blood clot in the spot where the tooth was removed. Comforting to know, this condition is not an infection, but rather a delay in the healing process, so there’s no need to worry about increased white blood cells, which usually indicate an infection.
Additional laboratory tests or x-rays are usually not necessary to diagnose alveolar osteitis. However, if your dentist suspects that there may be pieces of the tooth left behind or small pieces of dead bone (called bony sequestra), they might order a panoramic x-ray. This is a full picture of all your teeth and the bones that hold them.
It’s also worth noting that certain substances involved in blood clotting and breakdown, called markers of fibrinolysis, have been studied for their role in predicting the risk of heart disease. However, these substances are not useful in identifying or managing alveolar osteitis.
Treatment Options for Alveolar Osteitis (Dry Socket)
Currently, there is no unanimously agreed-upon treatment strategy for alveolar osteitis (also known as “dry socket”), a dental issue that can happen following tooth extraction. The primary goal for managing dry socket is providing relief from symptoms, not addressing a specific disease process.
The most universally accepted initial treatment for dry socket is intra-alveolar irrigation. This process involves cleaning out the empty tooth socket (the “alveolus”) of any dead tissue, debris, and bacteria. Although this might not directly relieve pain, it generally complements other treatment strategies. Curettage, which is a scraping or cleaning procedure, isn’t recommended as it could further expose the bone.
Topical numbing gels can be used after irrigation to provide temporary relief from pain. For more prolonged symptom relief, healthcare providers may use long-acting local anesthetics. Oral pain relievers, particularly a type of medication called non-steroidal anti-inflammatory drugs (NSAIDs), are often used in conjunction with local anesthetics.
Another strategy involves placing a medicated dressing into the empty tooth socket, either during surgery, or afterwards. There are several different types of dressings available, often including materials like zinc oxide eugenol, containing substances that can relieve pain or control bacteria. While several studies indicate that these dressings can be effective, they usually have to be taken out to avoid unwanted reactions and may delay healing. Recently, hyaluronic acid has achieved prominence for its potential to decrease pain and inflammation after application following irrigation.
Using chlorhexidine mouthwashes and gels has also been found to be effective. These products are often studied for their potential to prevent dry socket, but some studies have examined their use after dry socket has already developed. While some studies have shown success in managing dry socket with these products, there isn’t enough evidence to formally recommend them as a treatment.
Platelet-rich fibrin (PRF) has been studied as well. One study found that although the pain reduction it offers is similar to irrigation alone, it does seem to improve the healing of the skin tissue. However, PRF is typically used as a preventative measure and its effectiveness as a treatment remains questionable.
Low-level laser therapy (LLLT), also known as phototherapy, is a newer proposed treatment for controlling symptoms of dry socket. It is easy and quick to administer, relatively safe, and cost-effective. It is equal to, if not superior to, many other alternative management strategies. Moreover, photobiomodulation therapy, a type of light therapy, has helped to significantly decrease pain and is considered very effective by some. Since LLLT is still a newer concept, further research is needed before it’s widely adopted as a standard treatment.
What else can Alveolar Osteitis (Dry Socket) be?
If a person comes in within a week after having a tooth taken out and they’re in a lot of pain, they might have a condition known as alveolar osteitis. The level of pain can change how serious we think the condition might be. Sometimes, it’s just normal pain that comes after an operation, but other times, it could be because food got stuck in the spot where the tooth was.
Regardless of what’s causing the pain, treatment usually involves cleaning out the socket where the tooth was. However, there’s some debate among experts about the timeline of the pain. Some say that if pain is still happening a week after the surgery, it’s not alveolar osteitis. Others argue that if it lasts more than three weeks, it shouldn’t be diagnosed as alveolar osteitis.
When diagnosing the situation, doctors also consider the possibility of an infection, especially if there are signs of illness beyond the area where the tooth was extracted. If the symptoms of alveolar osteitis appear or continue weeks after the operation, doctors worry about other conditions like acute osteomyelitis, subperiosteal infection, or the formation of bony sequestra. Based on what the patient’s condition looks like, it might make sense to get a panoramic x-ray to check on how the healing is going.
What to expect with Alveolar Osteitis (Dry Socket)
Alveolar osteitis, often called ‘dry socket’, is a condition that naturally gets better on its own. This means that it typically has a very good outcome. Once treatment begins, the condition usually improves within a few days. Even without treatment, it doesn’t last long and won’t cause any long-term health issues.
Possible Complications When Diagnosed with Alveolar Osteitis (Dry Socket)
There is currently no evidence to suggest that alveolar osteitis can lead to further complications. When it has been resolved, the tooth removal site heals in the same way as in patients that never experienced alveolar osteitis. No scientific studies have shown a connection between alveolar osteitis and an increased risk of complications from tooth extraction.
Using chlorhexidine, the most supported preventative tactic, can occasionally cause serious side effects although these cases are rare. The main issue with chlorhexidine is that it can cause an allergy-type reaction. There have been several reported instances of minor side effects after an alveolar osteitis site was rinsed with chlorhexidine mouthwash.
In the UK, two reports have detailed severe and even fatal reactions to chlorhexidine used in irrigation for treating alveolar osteitis. These reactions were due to allergic responses. Dentists prescribing or administering this medication need to be aware of these potential allergic reactions and inform their patients of these possible side effects, both minor and severe.
Another known side effect of alveolar osteitis treatment is a possible foreign body reaction. The substances delivering the medication into the socket of the tooth can delay healing and stimulate this reaction. This reaction is due to inflammation and the body’s inability to break down and digest foreign materials. Therefore, medication dressings should be removed to prevent this reaction. Because of this, many experts advise against the use of topical medicines.
Important to Note:
- No specific complications linked to alveolar osteitis
- Chlorhexidine use can cause allergic reactions
- Chlorhexidine has rare but possible serious side effects
- Foreign body reaction is a possibility
Preventing Alveolar Osteitis (Dry Socket)
Preventing a condition known as alveolar osteitis, which is a painful dental condition that sometimes occurs after a tooth extraction, involves understanding the risk factors and the preventive measures available. There’s some disagreement about these risk factors, but it’s important for the doctor to explain them to you so you can lower your chances of getting this condition. This includes quitting smoking, which is shown to help prevent not only alveolar osteitis, but also several other complications. Women should know that their risk may be higher, especially if they’re using birth control pills. Controlling these kinds of factors could lower the chances of getting alveolar osteitis.
After a tooth extraction, doctors often advise patients to follow specific instructions to prevent complications. However, even when these instructions are followed, they may not significantly reduce the occurrence of alveolar osteitis.
One preventive measure that has garnered a lot of support is using something called chlorhexidine. A study found that using chlorhexidine mouthwash following tooth removal reduced the chances of getting alveolar osteitis by 63%. Another study confirmed that chlorhexidine gels were also effective for the same purpose. Whether in mouthwash or gel form, chlorhexidine has been widely shown to prevent this dental condition.
While a systematic review suggested that using chlorhexidine is safe with no significant side effects, it also pointed out that the evidence might not be powerful enough to universally recommend its use for preventing alveolar osteitis. Nonetheless, the majority of evidence does suggest that chlorhexidine, whatever its formulation might be, is safe and effective in reducing the chances of this condition.
Another thing to note is that most other preventive measures for alveolar osteitis lack sufficient evidence for their use. However, a solution of platelets taken from your own blood, referred to as platelet-rich fibrin (PRF), has shown promise in several studies. One study even found that combining PRF with chlorhexidine was particularly effective in reducing the occurrence of alveolar osteitis.
Results from other tactics like washing your mouth with a saline (salt) solution after surgery have been mostly positive. In fact, warm saltwater mouth baths have been found to reduce the chances of complications, including alveolar osteitis. More studies are recommended to establish standardized guidelines on how to get the most benefit from this method.
One thing that’s generally discouraged by current guidelines is using antibiotics to prevent or treat alveolar osteitis. Even though antibiotics are somewhat backed by evidence to reduce infections after tooth extractions, their effectiveness with alveolar osteitis is less solid. In fact, even in cases where they show a slight reduction or improvement in the condition, it’s often not enough to be statistically significant, and the chances for minor adverse reactions to antibiotics are probable. As a result, it’s suggested that antibiotics should not be used as a routine method for tooth extractions in patients with a healthy immune system.
