Your dentist or oral surgeon can evaluate your teeth and mouth to determine if you have impacted wisdom teeth or if another condition is causing your problems. Such evaluations typically include:
- Questions about your dental symptoms and general health
- An examination of the condition of your teeth and gums
- Dental X-rays that can reveal the presence of impacted teeth, as well as signs of damage to teeth or bone
If your impacted wisdom teeth are likely to be difficult to treat or if you have medical conditions that may increase surgical risks, your dentist will likely ask you to see an oral surgeon to discuss the best course of action.
Managing asymptomatic wisdom teeth
If impacted wisdom teeth aren't causing symptoms or apparent dental problems, they're called asymptomatic. Some disagreement exists in the dental community about how to manage asymptomatic impacted wisdom teeth. Research on this topic doesn't strongly favor one strategy over the other.
Some dentists and oral surgeons recommend removing asymptomatic wisdom teeth to prevent future potential problems. They argue:
- Symptom-free wisdom teeth may not be free of disease.
- If there isn't enough space for the teeth to erupt, it's often hard to get to them and clean them properly.
- Serious complications with wisdom teeth happen less often in younger adults.
- The procedure is more difficult and more likely to cause complications later in life, particularly among older adults.
Other dentists and oral surgeons recommend a more conservative approach. They note:
- There isn't enough evidence to suggest that impacted wisdom teeth not causing problems in young adulthood will later cause problems.
- The expense and risks of the procedure don't justify the expected benefit.
With a conservative approach, your dentist will monitor your teeth for decay, gum disease or other complications. He or she may recommend removing a tooth if problems arise.
Impacted wisdom teeth that are causing pain or other dental problems are usually surgically removed (extracted). Extraction of a wisdom tooth is usually required for:
- Infection or gum disease (periodontal disease) involving the wisdom teeth
- Tooth decay in partially erupted wisdom teeth
- Cysts or tumors involving the wisdom teeth
- Wisdom teeth that are causing damage to neighboring teeth
Extraction is almost always done as an outpatient procedure, so you'll go home the same day. The process includes:
- Sedation or anesthesia. You may have local anesthesia, which numbs your mouth; sedation anesthesia that depresses your consciousness; or general anesthesia, which makes you lose consciousness.
- Tooth removal. During an extraction your dentist or oral surgeon makes an incision in your gums and removes any bone that blocks access to the impacted tooth root. After removing the tooth, the dentist or oral surgeon typically closes the wound with stitches and packs the empty space (socket) with gauze.
Wisdom tooth extractions may cause some pain and bleeding, as well as swelling of the site or jaw. Temporarily, some people have trouble opening their mouth wide due to swelling of the jaw muscles. You'll receive instructions for caring for wounds and for managing pain and swelling, such as taking pain medication and using cold compresses to reduce swelling.
Much less commonly, some people may experience:
- Painful dry socket, or exposure of bone if the post-surgical blood clot is lost from the socket
- Infection in the socket from bacteria or trapped food particles
- Damage to nearby teeth, nerves, jawbone or sinuses
Coping and support
The thought of having a tooth removed may be overwhelming, but delaying care can lead to serious and permanent problems. It's important to talk to your dentist about your concerns. Anxiety is common and nothing to be embarrassed about. Ask your dentist for suggestions on how to cope with your anxiety and discomfort.
Many dentists offer ways to ease your anxiety, such as listening to music or watching videos. You may be able to bring along a supportive family member or friend. You can also learn relaxation techniques, such as deep breathing and imagery. If you have severe anxiety, talk to your dentist or oral surgeon about medications or sedative techniques that may help.
Preparing for your appointment
If you're experiencing symptoms or other dental problems that may indicate an impacted wisdom tooth, see your dentist as soon as possible.
Your dentist may ask you these questions:
- What symptoms are you experiencing?
- When did your symptoms begin?
- Does anything worsen symptoms, such as chewing toward the back of your mouth?
- Have you noticed any bleeding while brushing or flossing your teeth?
- What are your typical teeth-cleaning habits?
