The final emergence of permanent teeth in late adolescence marks the end of a long process beginning in the womb with the formation of our primary or “baby” teeth. Permanent teeth form in a similar way as buds high in the jaw, continuing to grow until the primary teeth ahead of them fall away. The crowns of the new adult teeth eventually break through the gum tissue and emerge (erupt) into view.
At least, that’s normally what should happen; sometimes, though, a tooth may only erupt partially or not at all, a condition known as impaction. The crown remains partially or fully submerged below the gum line, causing the tooth to press against other teeth, potentially damaging them. It can also make periodontal (gum) tissues adjacent to the area more susceptible to disease. Wisdom teeth are especially prone to this kind of impaction, to the extent they’re often surgically removed (extracted) to avoid future problems to adjacent teeth or the bite.
Upper canines (the “eye teeth” normally located directly below the eyes) are also subject to impaction. But because of their highly visible position, extracting them could have an adverse impact on the patient’s smile. In this case, we often attempt instead to expose and ultimately save the tooth.
Before taking any action, however, an orthodontic examination is conducted first to pinpoint the exact position of the impacted tooth and determine how that position might affect moving teeth into a more desired alignment. If we find the impacted canine is in a workable position, the next step is to surgically uncover the tooth from the gum tissue (a minor procedure usually performed by an oral surgeon or periodontist). Once exposed, an orthodontic bracket with a small attached gold chain is bonded to the tooth. The gums are then sutured back into place with the chain exposed and allowed to heal.
At some future point an orthodontist will attach the chain to orthodontic hardware that will pull the impacted tooth into proper position over several months. As a result, the upper canine becomes “un-impacted”; the dangers to surrounding teeth and tissues are also reduced. And, just as important, we can preserve the tooth and with orthodontics achieve an attractive, normal smile.

After ruling out other causes for your jaw pain, your doctor or dentist has made a diagnosis: a temporomandibular joint disorder (TMD). With TMD, your pain symptoms and other dysfunctions are due to a problem associated with the temporomandibular joint (TMJ) that connects your lower jaw (mandible) to your upper skull (cranium).
There are a number of treatment options, but most can be classified as either aggressive or conservative. Aggressive treatments are more interventional and target problems with the teeth such as bite problems or jaw relationships as they relate to the bite, which are thought to be underlying causes for TMD. Such treatments include orthodontics to realign teeth, crown or bridgework, or surgical treatment to the jaw or joint itself. These treatments are controversial and irreversible — with no guarantee of symptom relief.
It’s thought by many to be appropriate, then, to start with more conservative treatments. Many of these are based on treating the TMJ — which is a joint, a moveable bony structure connected by muscles and tendons — with an orthopedic approach, using treatments similar to those used for other joint problems.
Here, then, are some of those conservative therapies that may relieve your TMD pain and other symptoms.
Physical Therapy. Commonly used to treat pain and dysfunction in other joints, physical therapies like manual manipulation, massage, alternating hot and cold packs or exercises can be used to relax, stretch or retrain the muscles that operate the TMJ while reducing pain and inflammation.
Medications. Medications may be incorporated into the treatment plan to relieve pain, reduce inflammation or relax tense muscles. Besides prescription drugs, over-the-counter anti-inflammatory drugs (such as ibuprofen or acetaminophen) are also commonly used.
Bite Appliances. If night-time teeth grinding or clenching habits are a primary cause for the TMD, you may benefit from wearing an occlusal bite guard while you sleep, designed to specifically fit your upper teeth. Because the lower teeth can’t grip the guard’s smooth plastic surface when biting down, they’ll more likely produce less force. This gives the jaw muscles a chance to relax during sleep.
Diet changes. Changing to softer foods, which don’t require strenuous chewing, and eliminating the chewing gum habit will further help reduce stress on the TMJs and also give your muscles a chance to relax and heal.
