WeMayBeAbleToTreatSomeBiteProblemsEarly

In any given year, 4 million tweens and teens are in the process of having their teeth straightened with braces or clear aligners. It's so common we tend to consider orthodontic treatment for young people as a rite of passage into adulthood.

But it doesn't necessarily have to be that way—it might be possible to stop or at least minimize a poor bite before it fully develops. That's the goal of interceptive orthodontics—treatments that head off or “intercept” a bite problem early.

The goal isn't necessarily to reposition misaligned teeth, but to correct a problem that can lead to misalignment. Here are some examples.

A narrow jaw. A narrowly developing jaw can crowd incoming teeth out of their normal positions. For the upper jaw, though, we can take advantage of a temporary separation in the bones in the roof of the mouth (palate) with a device called a palatal expander. Placed against the palate, the expander exerts outward pressure on the teeth and jaw to widen this separation. The body fills in the gap with bone to gradually widen the jaw.

Abnormal jaw alignment. It's possible for a jaw to develop abnormally during childhood so that it extends too far beyond the other. Using a hinged device called a Herbst appliance, it's possible to interrupt this abnormal growth pattern and influence the bones and muscles of the jaw to grow in a different way.

Missing primary teeth. An important role for a primary (baby) tooth is to hold a place for the future permanent tooth. But if the primary tooth is lost too soon, other teeth can drift into the space and crowd out the intended permanent tooth. To prevent this, we can insert a space maintainer: This simple looped metal device prevents teeth from drifting and preserves the space for the permanent tooth.

Although these and other interceptive treatments are effective, some like the palatal expander do their best work within a limited age frame. To take advantage of interceptive orthodontics in a timely manner, parents should seek a bite evaluation for their child from an orthodontist around age 6. The earlier we detect a growing bite problem, the greater your chances for successful intervention.

KeepYourNewStraightenedSmileStraightWithanOrthodonticRetainer

You can't correct a poor bite with braces or clear aligners overnight: Even the most cut-and-dried case can still require a few years to move teeth where they should be. It's a welcome relief, then, when you're finally done with braces or aligner trays.

That doesn't mean, however, that you're finished with orthodontic treatment. You now move into the next phase—protecting your new smile that took so much to gain. At least for a couple of more years you'll need to regularly wear an orthodontic retainer.

The name of this custom-made device explains its purpose: to keep or “retain” your teeth in their new, modified positions. This is necessary because the same mechanism that allows us to move teeth in the first place can work in reverse.

That mechanism centers around a tough but elastic tissue called the periodontal ligament. Although it primarily holds teeth in place, the ligament also allows for tiny, gradual tooth movement in response to mouth changes. Braces or aligner trays take advantage of this ability by exerting pressure on the teeth in the direction of intended movement. The periodontal ligament and nature do the rest.

But once we relieve the pressure when we remove the braces or aligners, a kind of “muscle memory” in the ligament can come into play, causing the teeth to move back to where they originally were. If we don't inhibit this reaction, all the time and effort put into orthodontic treatment can be lost.

Retainers, either the removable type or one fixed in place behind the teeth, gently “push” or “pull” against the teeth (depending on which type) just enough to halt any reversing movement. Initially, a patient will need to wear their retainer around the clock. After a while, wear time can be reduced to just a few hours a day, usually during sleep-time.

Most younger patients will only need to wear a retainer for a few years. Adults who undergo teeth-straightening later in life, however, may need to wear a retainer indefinitely. Even so, a few hours of wear every day is a small price to pay to protect your beautiful straightened smile.

LingualBracesMightbeaBetterFitforYourActiveLifestyle

If you've decided to straighten your teeth, you've made a wise choice for both your dental health and your smile. Now you may be facing another decision—which method to use for bite correction.

Not too long ago people had only one choice—traditional braces all the way. But that changed with the introduction of clear aligners, a series of removable plastic trays worn one after the other to realign teeth. In all but a few situations, clear aligners accomplish the same outcome as braces but without the conspicuous appearance and, thanks to their removability, difficulty in brushing and flossing teeth.

And now, a recent innovation in orthodontics could give you a third option—lingual braces. These are braces fixed to the back of teeth adjacent to the tongue (hence the term “lingual”), rather than on the front as with traditional braces. They essentially perform the same action, only instead of “pushing” teeth like traditional braces, they “pull” the teeth to the target positions. Lingual braces may also ease certain disadvantages people find with traditional braces or clear aligners.

If you're into martial arts, for instance, you may encounter blows to the face that increase your injury risk while wearing traditional braces. Likewise, if you're highly social, clear aligners can be a hassle to take out and keep up with if you're frequently eating in public. Lingual braces answer both types of issues: They won't damage your lips or gums in the case of blunt force facial contact; and they remain out of sight, out of mind in social situations.

Before considering lingual braces, though, keep in mind that they may cost 15-35 percent more than traditional braces. They also take time for some people to get used to because of how they feel to the tongue. And, they're not yet as widely available as traditional braces, although the number of orthodontists who have received training in the new method is increasing.

If you'd like to know more about lingual braces and whether they're right for you, speak to your dentist or orthodontist. You may find that this new option for improving your dental health and your smile fits your lifestyle.

InterceptiveOrthodonticsStoppingPoorBitesBeforeTheyDevelop

Approximately 4 million tweens and teens are currently undergoing orthodontic treatment for a poor bite (malocclusion) that can cost their families thousands of dollars in braces or clear aligners. But treatment doesn't always have to follow this track: Found early, many malocclusions can be corrected or minimized before they fully develop.

Known as interceptive orthodontics, this particular approach to bite correction often begins as early as 6-10 years of age. Rather than move existing teeth, interceptive orthodontics focuses instead on redirecting jaw growth and intervening in other situations that can cause malocclusions.

For example, a child's upper jaw may not be growing wide enough to accommodate all incoming permanent teeth, crowding later arrivals out of their proper positions. But taking advantage of a gap during early childhood that runs through the center of the palate (roof of the mouth), orthodontists can increase jaw width with a device called a palatal expander.

The expander fits up against the palate with “legs” that extend and make contact with the inside of the teeth. With gradually applied pressure, the expander widens the central gap and the body naturally fills it with new bone cells. The bone accumulation causes the jaws to widen and create more room for incoming teeth.

Another way a malocclusion can develop involves the primary or “baby” teeth. As one of their purposes, primary teeth serve as placeholders for the future permanent teeth forming in the gums. But if they're lost prematurely, adjacent teeth can drift into the vacant space and crowd out incoming teeth.

Dentists prevent this with a space maintainer, a thin metal loop attached to the adjoining teeth that puts pressure on them to prevent them from entering the space. This spacer is removed when the permanent tooth is ready to erupt.

These and other interceptive methods are often effective in minimizing the formation of malocclusions. But it's often best to use them early: Palatal expansion, for example, is best undertaken before the central gap fuses in early puberty, and space maintainers before the permanent tooth erupts.

That's why we recommend that children undergo an orthodontic evaluation around age 6 to assess their early bite development. If a malocclusion looks likely, early intervention could prevent it and reduce future treatment costs.

PracticeDailyHygienetoAvoidGumSwellingWhileWearingBraces

Straightening your smile doesn't happen overnight—it can involve months or even years of orthodontic treatment. And although the end result is well worth it, the long process can make it difficult to keep your gums healthy, especially while wearing braces.

Gum swelling in particular is a common problem for braces wearers with two potential sources. First, orthodontic hardware makes it difficult to keep teeth clean of dental plaque, a thin bacterial film that can cause gum disease. Plaque and its hardened counterpart tartar can trigger a gum infection, which in turn triggers inflammation. As a result, affected gums appear swollen and red, and can easily bleed.

Gum tissues may also react to braces pressing against them and develop hypertrophy (or hyperplasia), an increase in individual tissue cell growth. If this overgrowth occurs, it may not get resolved until after your braces have been removed.

As long as the hypertrophy doesn't appear to have weakened gum attachment with the teeth, it's usually not a big concern. But what is a concern is that hypertrophy could increase a braces wearer's difficulties with oral hygiene and give rise to a true gum infection that could endanger dental attachment. Advanced cases could require surgical correction or removal of the braces altogether to adequately treat the infection.

The best way to avoid a worst case scenario is to be as diligent as possible with daily brushing and flossing. Fortunately, there are several tools that can make it easier with braces. Interproximal brushes, tiny brushes that can fit into the narrow spaces between the teeth and the braces, can be used in conjunction with your regular toothbrush.

Flossing is also easier if you use a floss threader or a water flosser. The latter utilizes a pump to emit a pulsating jet of water to break loose plaque between teeth and flush it away. Clinical studies have shown the effectiveness of water flossers for removing plaque in braces wearers as opposed to not flossing at all.

A faithful daily hygiene practice and twice-a-year cleanings and checkups with your regular dentist can help minimize your chances of gum swelling. Doing so will help ensure you'll complete your orthodontic treatment on the way to healthier and more attractive smile.
