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.

Along with thumb sucking, childhood teeth grinding is one of the top concerns anxious parents bring to their dentists. It’s so prevalent, though, many providers consider it normal behavior—the sleep-disturbing sound it can generate is often the worst consequence for the habit.
But that doesn’t mean you should brush aside all concern, especially if the habit continues into late childhood. Long-term teeth grinding could eventually damage the teeth and gums.
Teeth grinding (or clenching) is the involuntary movement of the jaws when not engaged in normal functions like chewing, speaking or swallowing. The action often produces higher than normal chewing forces, which over time can accelerate tooth wear, cause fractures, or contribute to loose teeth, all of which could increase the risk of dental disease. While it can occur at any time it’s most common among children during nighttime sleep.
While stress is the usual trigger for teeth grinding in adults, with young children the causes for the habit are more complex and less understood. Most doctors hold to the theory that most pediatric teeth grinding arises during shifts from lighter to heavier, rapid-eye-movement (REM) sleep. The child’s immature neuromuscular chewing control may engage involuntarily during this shift. Teeth grinding is also prevalent among children who snore or mouth-breathe, or who take anti-depressant medication.
But as mentioned before, there’s usually no cause for concern unless the habit persists beyond about age 11. If the habit isn’t fading, you should speak to your dentist about ways to reduce it or its effects. One way is with a custom-made night guard worn during sleep. The smooth, plastic surface of the appliance prevents teeth from making solid contact with each other during a grinding episode.
You might also seek treatment from an ear, nose and throat (ENT) specialist if your child is having issues with airway obstruction, which could also relieve teeth grinding. And children experiencing stressful situations or events may find relief both emotionally and physically from psychological therapy.
At younger ages, you can safely regard your child’s grinding habit as normal. But if it persists, it’s worth looking for ways to reduce it.

If you have chronic jaw pain, you know how difficult eating, speaking or even smiling can be. Many sufferers will do anything to gain relief, even surgery. But before you go down that road, consider the traditional conservative approach to temporomandibular disorders (TMD) management first—it could provide the most relief with the least risk of side effects.
The temporomandibular joints connect the lower jaw to the skull on either side of the head. These ball and socket joints also contain a cushioning disk to facilitate movement. This disk is believed to be the primary focus for jaw pain problems known collectively as TMD.
Doctors now believe injury, stress, metabolic issues, jaw anatomy defects or similar factors trigger the chain reaction of muscle spasms, pain and soreness that can erupt during a TMD episode. A TMD patient may experience pain within the jaw muscles or joints themselves, clicking sensations, or an inability to open the jaw to its full range.
TMD therapy has traditionally followed an orthopedic path—treating jaw joints like any other joint. In recent years, though, a more aggressive treatment model has emerged that promotes more invasive techniques like orthodontics, dental work or jaw surgery to relieve discomfort. But the track record for this model, especially concerning jaw surgery, remains hazy at best and offers no guarantee of relief. These techniques are also irreversible and have even made symptoms worse in some patients.
It’s usually prudent, then, to try conservative treatments first. This can include pain and muscle relaxant medication, jaw exercises, stretching and massage, and dietary changes to reduce chewing force. Patients with teeth grinding habits may also benefit from a bite guard worn at night to reduce the biting force during sleep and help the joints relax.
By finding the right mix of treatments, you may be able to find significant relief from TMD symptoms with the conservative approach. If not, you might then discuss more invasive options with your dentist. But even if your dentist recommends such a procedure, you would be wise to seek a second opinion.
TMD can definitely interfere with your quality of life and peace of mind. But there are ways to reduce its effects and make for a happier life.
