YourTeenCouldgetaStraighterSmilewithClearAlignersRatherthanBraces

Your teen is about to embark on an orthodontic journey to a straighter, more attractive smile. But although you're excited about the outcome, you both may be steeling yourselves for a few years of "life with braces."

But maybe not—your teen may be able to take advantage of a different kind of corrective appliance: clear aligners. This 21st Century teeth movement method has a number of advantages over braces. For teens, though, there's one big one that could have a huge impact on their social life—clear aligners are nearly invisible to other people.

Clear aligners consist of a series of clear, removable, computer-generated trays based on photographs, models and x-rays of an individual patient's teeth and bite. Each of the trays is slightly different from the previous one in the series, and by wearing each one for about two weeks before moving on to the next, the aligners gradually move the teeth to the desired new positions.

Besides reducing embarrassment often associated with wearing metal braces, clear aligners have other benefits. Unlike braces, they can be removed for eating, easier oral hygiene or for rare special occasions (although for best effectiveness, they should be worn for 20 to 22 hours each day). Recent developments like added elements that help target certain teeth for movement or "power ridges" for more controlled and efficient force have increased the range of bite problems they can be used to correct.

While this means clear aligners can be used for many bite problems, in some severe cases braces and other orthodontic treatments might still be necessary. And because they're not fixed like braces (only the orthodontist can remove them) the patient must have the maturity and self-discipline to wear them consistently.

Your teen will need to undergo a thorough orthodontic examination to see if clear aligners are a viable option for them. If so, it could make the next few treatment years less stressful for both of you.

RemovingTeethCouldImprovetheOutcomeforaCrowdedBite

The primary goal of dental care is to preserve teeth. But there are circumstances in which removing a tooth, even a relatively healthy one, could prove best in the long run.

A malocclusion (poor bite) related to crowding might fit such a circumstance. Crowding occurs when the size of the jaw is too small for the teeth coming in. With not enough space, some teeth could erupt out of their proper positions. Removing certain teeth frees up space to eventually allow braces or other orthodontic devices to re-align the teeth.

The teeth most frequently removed are the first bicuspids, located between the cuspid (the "eyeteeth" directly under the eyes) and the back teeth, and the second premolar. Removing these won't normally affect appearance or functionality once orthodontic or cosmetic treatments are complete.

Because of the mechanics of jaw development it might be necessary to perform these extractions several years before orthodontic treatment. This could create another potential problem: the time lag could adversely affect bone health.

This is because bone, as living tissue, has a life cycle with cells forming, functioning and then dissolving, and new cells taking their place. When teeth are chewing or in contact with each other they generate force that travels through the tooth roots to the bone and stimulates cell growth at a healthy replacement rate.

But when a tooth is missing, so is this stimulation. This slows the replacement rate and eventually leads to decreased bone volume. Too much bone loss could create obstacles for orthodontic treatment or a future dental implant.

To avoid this, the dentist will often place a bone graft with processed bone mineral within the empty tooth socket right after extraction. The graft serves as a scaffold for bone cells to grow upon. The graft (plus any other added growth boosters) can help maintain a healthy level of bone volume to facilitate future orthodontic or restorative treatments.

Since targeted extraction for orthodontics is time-sensitive, you should have your child's bite evaluated by an orthodontist by age 7 to see if any action is necessary. The earlier a malocclusion is detected, the more likely a more attractive and healthy smile will be the ultimate outcome.
