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.

There's ample evidence tobacco smoking increases your risk for tooth decay and periodontal (gum) disease. But the same may be true for electronic cigarettes (E-cigs): Although millions have turned to “vaping” believing it's a safer alternative to smoking, there are growing signs it might also be harmful to oral health.
An E-cig is a device with a chamber that holds a liquid solution. An attached heater turns the liquid into a vapor the user inhales, containing nicotine, flavorings and other substances. Because it doesn't contain tar and other toxic substances found in tobacco, many see vaping as a safer way to get a nicotine hit.
But a number of recent research studies seem to show vaping isn't without harmful oral effects. A study from Ohio State University produced evidence that E-cig vapor interferes with the mouth's bacterial environment, or oral microbiome, by disrupting the balance between harmful and beneficial bacteria in favor of the former. Such a disruption can increase the risk for gum disease.
Other studies from the University of Rochester, New York and Universit? Laval in Quebec, Canada also found evidence for vaping's negative effects on oral cells. The Rochester study found astringent flavorings and other substances in vaping solutions can damage cells. The Quebec study found a staggering increase in the normal oral cell death rate from 2% to 53% in three days after exposure to E-cig vapor.
Nicotine, E-cig's common link with tobacco, is itself problematic for oral health. This addictive chemical constricts blood vessels and reduces blood flow to the mouth's tissues. This not only impedes the delivery of nutrients to individual cells, but also reduces available antibodies necessary to fight bacterial infections. Regardless of how nicotine enters the body—whether through smoking or vaping—it can increase the risk of gum disease.
These are the first studies of their kind, with many more needed to fully understand the effects of vaping on the mouth. But the preliminary evidence they do show should cause anyone using or considering E-cigs as an alternative to smoking to think twice. Your oral health may be hanging in the balance.
Kathy Bates has been a familiar face to filmgoers since her Oscar-winning performance as Annie Wilkes in Misery. She's best known for playing true-to-life characters like Wilkes or Barbara Jewell in last year's Richard Jewell (for which she earned her fourth Oscar nomination). To keep it real, she typically eschews cosmetic enhancements—with one possible exception: her smile.
Although happy with her teeth in general, Bates noticed they seemed to be “moving around” as she got older. This kind of misalignment is a common consequence of the aging process, a result of the stresses placed on teeth from a lifetime of chewing and biting.
Fortunately, there was an orthodontic solution for Bates, and one compatible with her film career. Instead of traditional braces, Bates chose clear aligners, a newer method for moving teeth first introduced in the late 1990s.
Clear aligners are clear, plastic trays patients wear over their teeth. A custom sequence of these trays is developed for each patient based on their individual bite dimensions and treatment goals. Each tray in the sequence, worn in succession for about two weeks, places pressure on the teeth to move in the prescribed direction.
While clear aligners work according to the same teeth-moving principle as braces, there are differences that make them more appealing to many people. Unlike traditional braces, which are highly noticeable, clear aligners are nearly invisible to others apart from close scrutiny. Patients can also take them out, which is helpful with eating, brushing and flossing (a challenge for wearers of braces) and rare social occasions.
That latter advantage, though, could pose a problem for immature patients. Clear aligner patients must have a suitable level of self-responsibility to avoid the temptation of taking the trays out too often. Families of those who haven't reached this level of maturity may find braces a better option.
Clear aligners also don't address quite the range of bite problems that braces can correct. Some complex bite issues are thus better served by the traditional approach. But that gap is narrowing: Recent advances in clear aligner technology have considerably increased their treatability range.
With that said, clear aligners can be an ideal choice for adults who have a treatable bite problem and who want to avoid the appearance created by braces. And though they tend to be a little more expensive than braces, many busy adults find the benefits of clear aligners to be worth it.
The best way to find out if clear aligners could be a viable option for you is to visit us for an exam and consultation. Like film star Kathy Bates, you may find that this way of straightening your smile is right for you.
