What makes an attractive smile? Of course, shiny, straight and defect-free teeth are a big factor. But there’s another equally important element: all your teeth have come in.
Sometimes, though, they don’t: one or more teeth may remain up in the gums, a condition known as impaction. And if they’re in the front like the upper canines (the pointed teeth on either side of the front four incisors) your smile’s natural balance and symmetry can suffer.
Impaction usually happens due to lack of space on a small jaw. Previously erupted teeth crowd into the space of teeth yet to come in, preventing them from doing so. As a result the latter remain hidden within the gums.
While impaction can interfere with the smile appearance, it can cause health problems too. Impacted teeth are at higher risk for abscesses (localized areas of infection) and can damage the roots of other teeth they may be pressing against. That’s why it’s desirable for both form and function to treat them.
We begin first with an orthodontic examination to fully assess the situation. At some point we’ll want to pinpoint the impacted teeth’s precise location and position. While x-rays are useful for locating impacted teeth, many specialists use cone beam CT (CBCT) technology that produces highly detailed three-dimensional images viewable from different vantage points.
If the tooth is in too extreme a position, it might be best to remove it and later replace it with a dental impact or similar restoration once we’ve completed other necessary orthodontic treatment. But if the tooth is in a reasonable position, we might be able to “move” the tooth into its proper place in the jaw in coordination with these other tooth-movement efforts to make room for it.
To begin this process, an oral surgeon or periodontist surgically exposes the tooth crown (the normally visible portion) through the gums. They then bond a small bracket to the crown and attach a small gold chain. An orthodontist will attach the other end to orthodontic hardware that will exert downward pressure on the tooth to gradually bring it into normal position.
Dealing with impacted teeth of this nature is often part of a comprehensive effort to correct the bite. If we’re successful, it could permanently transform both the smile and overall dental health.

Your mouth is a lot like the Wild West — home to millions of bacteria and other microbes, some of which are definitely not “the good guys.” But your teeth are well-protected from these hostile forces and their acidic waste products: with enamel shielding the visible part of your tooth, your gums protect the parts you can’t see.
As effective as they are, though, your gums aren’t invincible: their greatest threat is periodontal (gum) disease. This bacterial infection arises from plaque, a thin film of bacteria and food particles accumulating on teeth due to inadequate brushing and flossing.
The infected tissues soon become inflamed (red and swollen), a natural defensive response from the immune system. The longer they’re inflamed, however, the more likely they’ll begin detaching from the teeth. The gums may eventually shrink back or recede from the teeth, often causing them to appear “longer” because more of the tooth is now exposed to view.
Gum recession doesn’t bode well for your teeth’s survival: the exposed tooth and underlying bone can become even more susceptible to infection and damage. In the end, you could lose your tooth and portions of the supporting bone.
Treatment depends on the severity of the gum recession. In mild to moderate cases, we may only need to perform the standard gum disease treatment of removing plaque and calculus from all gum and tooth surfaces (including below the gum line) with special instruments. This helps reduce the infection and allow the gums to heal and re-establish attachment with the tooth. In more advanced cases, though, the recession may be so extensive we’ll need to graft donor tissue to the area using one of a variety of surgical techniques.
Although the right treatment plan can help restore your gum health, there’s another approach that’s even better — preventing gum disease in the first place. You can reduce your disease risk by practicing daily brushing and flossing and visiting your dentist regularly or when you see symptoms like gum swelling or bleeding. Taking care of your gums won’t just save your smile — it might also save your teeth.
