Due to flooding from the tropical storm, the Middletown Urgent Care location has temporarily relocated to 520 Saybrook Road, Suite N100 Middletown, CT. The hours for Middletown Urgent Care will remain the same.
Impacted wisdom teeth are third molars at the back of the mouth that don't have enough room to emerge or develop normally.
Wisdom teeth are the last adult teeth to come into the mouth (erupt). Most people have four wisdom teeth at the back of the mouth — two on the top, two on the bottom.
Impacted wisdom teeth can result in pain, damage to other teeth and other dental problems. In some cases, impacted wisdom teeth may cause no apparent or immediate problems. But because they're hard to clean, they may be more vulnerable to tooth decay and gum disease than other teeth are.
Impacted wisdom teeth that cause pain or other dental complications are usually removed. Some dentists and oral surgeons also recommend removing impacted wisdom teeth that don't cause symptoms to prevent future problems.
Impacted wisdom teeth don't always cause symptoms. However, when an impacted wisdom tooth becomes infected, damages other teeth or causes other dental problems, you may experience some of these signs or symptoms:
Red or swollen gums
Tender or bleeding gums
Swelling around the jaw
An unpleasant taste in your mouth
Difficulty opening your mouth
When to see a doctor
See your dentist if you experience symptoms in the area behind your last molar that may be associated with an impacted wisdom tooth.
Wisdom teeth (third molars) become impacted because they don't have enough room to come in (erupt) or develop normally.
Wisdom teeth usually emerge sometime between the ages of 17 and 25. Some people have wisdom teeth that emerge without any problems and line up with the other teeth behind the second molars. In many cases, however, the mouth is too crowded for third molars to develop normally. These crowded third molars become trapped (impacted).
An impacted wisdom tooth may partially emerge so that some of the crown is visible (partially impacted), or it may never break through the gums (fully impacted). Whether partially or fully impacted, the tooth may:
Grow at an angle toward the next tooth (second molar)
Grow at an angle toward the back of the mouth
Grow at a right angle to the other teeth, as if the wisdom tooth is "lying down" within the jawbone
Grow straight up or down like other teeth but stay trapped within the jawbone
Impacted wisdom teeth can cause several problems in the mouth:
Damage to other teeth. If the wisdom tooth pushes against the second molar, it may damage the second molar or increase the risk of infection in that area. This pressure can also cause problems with crowding of the other teeth or require orthodontic treatment to straighten other teeth.
Cysts. The wisdom tooth develops in a sac within the jawbone. The sac can fill with fluid, forming a cyst that can damage the jawbone, teeth and nerves. Rarely, a tumor — usually noncancerous (benign) — develops. This complication may require removal of tissue and bone.
Decay. Partially impacted wisdom teeth appear to be at higher risk of tooth decay (caries) than other teeth. This probably occurs because wisdom teeth are harder to clean and because food and bacteria get easily trapped between the gum and a partially erupted tooth.
Gum disease. The difficulty cleaning impacted, partially erupted wisdom teeth increases the risk of developing a painful, inflammatory gum condition called pericoronitis (per-ih-kor-o-NI-tis) in that area.
You can't keep an impaction from occurring, but keeping regular six-month dental appointments for cleaning and checkups enables your dentist to monitor the growth and emergence of your wisdom teeth. Regularly updated dental X-rays may indicate impacted wisdom teeth before any symptoms develop.
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 an 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?
