If you’ve ever looked at younger photos of yourself, you’re sure to notice differences with your present appearance. Of course, your basic features might appear much the same. But maybe your lips seemed a little thicker back then, or your nose a bit less prominent.
This is because your facial features don’t stop growing when you reach adulthood—they continue to change throughout your life. For example, lips reach their maximum thickness by around age 14 for girls or age 16 for boys; they’ll remain at that level of thickness for a few years before gradually thinning throughout adulthood. The nose will also continue to grow, becoming more prominent especially as changes in the lower part of the face can make the chin appear shorter.
Although each of us ages at different rates and in different ways, these general physical trends are somewhat predictable. That’s why we can use the knowledge of how our facial physiology changes with age to fine tune orthodontic or other cosmetic dental treatments. The most optimum approach is to consider treatment in the early stages of bite development during childhood or early adolescence.
This means we’re doing more than correcting a patient’s current bite: we’re also taking into account how tooth movement now might affect the jaw and facial structures later in life. By incorporating our understanding of age-related changes into our treatment we might be able to provide some hedge against the effects of aging.
This approach starts with early comprehensive dental care, preferably before a child’s first birthday, and an orthodontic evaluation at around age 6 to assess bite development. It may also be necessary to initiate interceptive treatment at an early age to lessen or even eliminate a growing bite problem to help ease the extent of future treatment. And if a bite requires correction, early evaluation can help create a timetable for effective treatment in later years.
Taking this approach can correct problems now affecting both dental health and appearance. But by acknowledging the aging process in our treatments, we can build the foundation for a beautiful smile well into the future.
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.

If you're currently undergoing orthodontic treatment, you're no doubt looking forward to the day your braces come off. But that won't end your treatment just yet — you'll need to wear a retainer.
Teeth are held secure in the bone of the jaw by an elastic tissue known as the periodontal ligament. As the braces “pull” the teeth to their new position, the ligament stretches and the bone remodels around the teeth. But the ligament also has a tendency to rebound as the tension eases when the braces are removed. The teeth could then return to their original position, especially during the first few months.
To prevent this patients wear an orthodontic appliance known as a retainer. It maintains some of the tension once supplied by the braces to help keep or “retain” the teeth in their new position. Depending on your age and other factors, you'll have to wear one for at least eighteen months; some patients, especially adults, may have to wear one indefinitely.
You may be familiar with a removable retainer, one you can take in and out of your mouth. But there's another type called a bonded retainer that's fixed to the teeth and can only be removed by a dentist. With this retainer a dentist bonds a thin piece of wire to the back of the teeth where it can't be seen. You can feel it, though, with the tongue: an unusual sensation at first, but one easily grown accustomed to.
Unlike their removable counterparts, bonded retainers aren't noticeable, either to others or the wearer. They're especially appropriate for patients who may not be as diligent in wearing a removable retainer.
It does, though, have some disadvantages. The position of the wire running horizontally across several teeth can make flossing difficult. And as with any retainer, removing it could increase the risk of the teeth moving out of alignment.
There are a number of factors to discuss with your orthodontist about which type of retainer is best for your situation. If you do choose a bonded retainer, be sure you work with the dental hygienist on how best to floss the affected teeth. And if you do have it removed, have a removable retainer prepared so you can preserve that smile you've invested so much into obtaining.
