3WaysOrthodonticTechniquesCouldPreventaPoorBite

While orthodontists can effectively correct most poor bites (malocclusions), some can be quite complex requiring much time and expense. But there's good news—we often don't have to wait on a malocclusion to fully develop if we catch it in time. Thanks to interceptive orthodontics, we may be able to intervene much earlier and eliminate or reduce the degree of difficulty with treatment.

Interceptive orthodontics is a group of techniques and devices used in early childhood to help deter a possible malocclusion. Here are 3 ways this approach could make a difference in your child's bite development.

Guiding jaw growth. On a normal-sized upper jaw, the permanent teeth usually have ample room to erupt. Not so with a smaller jaw: incoming teeth become crowded and may erupt out of alignment or too close to each other. Orthodontists often use a device called a palatal expander to aid an under-sized jaw in its development. The device fits along the roof of the mouth between the teeth and applies gradual outward pressure on them. This encourages the jaw to widen as it grows, thus providing more room for erupting teeth to come in properly and decrease the chances of obstructive sleep apnea in the future.

Reshaping and repositioning jaw bones. An overbite can occur when the jaws aren't properly aligned, often due to poor muscle and bone development. This is where devices like the Herbst appliance are useful. Its hinge mechanism encourages the lower jaw to grow further forward. The jaws can thus develop in a more normal way, minimizing the development of a malocclusion.

Maintaining space. Primary ("baby") teeth are important for dental development because they help guide future permanent teeth to erupt properly; they also keep nearby teeth from drifting into the intended space. But when a primary tooth is lost prematurely due to disease or trauma, the space can become vulnerable to this kind of "drift." With a simple mechanism called a space maintainer we can hold open the space created by a prematurely lost primary tooth until the permanent tooth is ready to erupt.

These and other techniques can help stop bad bites from developing in young children, minimizing or even eliminating the need for future orthodontic treatment. That means a healthier mouth for your child and less impact on your wallet.

CrazyLittleThingCalledHyperdontia

The movie Bohemian Rhapsody celebrates the iconic rock band Queen and its legendary lead vocalist, Freddie Mercury. But when we see pictures of the flamboyant singer, many fans both old and new may wonder—what made Freddie’s toothy smile look the way it did? Here’s the answer: The singer was born with four extra teeth at the back of his mouth, which caused his front teeth to be pushed forward, giving him a noticeable overbite.

The presence of extra teeth—more than 20 primary (baby) teeth or 32 adult teeth—is a relatively rare condition called hyperdontia. Sometimes this condition causes no trouble, and an extra tooth (or two) isn’t even recognized until the person has an oral examination. In other situations, hyperdontia can create problems in the mouth such as crowding, malocclusion (bad bite) and periodontal disease. That’s when treatment may be recommended.

Exactly what kind of treatment is needed? There’s a different answer for each individual, but in many cases the problem can be successfully resolved with tooth extraction (removal) and orthodontic treatment (such as braces).┬áSome people may be concerned about having teeth removed, whether it’s for this problem or another issue. But in skilled hands, this procedure is routine and relatively painless.

Teeth aren’t set rigidly in the jawbone like posts in cement—they are actually held in place dynamically by a fibrous membrane called the periodontal ligament. With careful manipulation of the tooth, these fibers can be dislodged and the tooth can be easily extracted. Of course, you won’t feel this happening because extraction is done under anesthesia (often via a numbing shot). In addition, you may be given a sedative or anti-anxiety medication to help you relax during the procedure.

After extraction, some bone grafting material may be placed in the tooth socket and gauze may be applied to control bleeding; sutures (stitches) are sometimes used as well. You’ll receive instructions on medication and post-extraction care before you go home. While you will probably feel discomfort in the area right after the procedure, in a week or so the healing process will be well underway.

Sometimes, dental problems like hyperdontia need immediate treatment because they can negatively affect your overall health; at other times, the issue may be mainly cosmetic. Freddie Mercury declined treatment because he was afraid dental work might interfere with his vocal range. But the decision to change the way your smile looks is up to you; after an examination, we can help you determine what treatment options are appropriate for your own situation.

LingualBracesOfferaLessVisibleAlternativetoTraditionalBraces

We’re all familiar with tried and true traditional braces and perhaps with newer clear aligners for realigning teeth. But there’s an even more novel way that’s quickly becoming popular: lingual braces.

This type of braces performs the same function as the traditional but in an opposite way. Rather than bonded to the front of the teeth like labial (“lip-side”) braces, these are bonded to the back of the teeth on the tongue (or “lingual”) side. While labial braces move teeth by applying pressure through “pushing,” lingual braces “pull” the teeth to where they need to be.

Although lingual braces are no better or worse than other orthodontic methods, they do have some advantages if you’re involved in sports or similar physical activities where mouth contact with traditional braces could cause lip or gum damage, or if your work or lifestyle includes frequent snacking or eating, which requires continually removing clear aligners. And like aligners, lingual braces aren’t noticeable to the outside world.

But lingual braces typically cost more: as much as 15-35% more than traditional braces. They can initially be uncomfortable for patients as the tongue makes contact with the hardware. While most patients acclimate to this, some don’t. And like traditional braces, it’s hard to effectively brush and floss your teeth while wearing them. This can be overcome, though, by using a water flosser and scheduling more frequent dental cleanings while you’re wearing them.

For the most part, lingual braces can correct any poor bite (malocclusion) correctable with labial braces. The treatment time is also comparable, ranging from several weeks to a couple of years depending on the malocclusion. And, as with any other orthodontic method, you’ll need to wear a retainer once they’re removed.

Lingual braces have only been available in a limited fashion for a few years, but their availability is growing as more orthodontists train in the new method. If you’re interested in the lingual braces approach, talk to your orthodontist or visit www.lingualbraces.org to learn more.

TheTimelyUseofaPalatalExpanderCouldHelpCorrectaCross-Bite

While crooked teeth are usually responsible for a malocclusion (poor bite), the root cause could go deeper: a malformed maxilla, a composite structure composed of the upper jaw and palate. If that’s the case, it will take more than braces to correct the bite.

The maxilla actually begins as two bones that fit together along a center line in the roof of the mouth called the midline suture, running back to front in the mouth. The suture remains open in young children to allow for jaw growth, but eventually fuses during adolescence.

Problems arise, though, when these bones don’t fully develop. This can cause the jaw to become too narrow and lead to crowding among the erupting teeth and a compromised airway that can lead to obstructive sleep apnea. This can create a cross-bite where the upper back teeth bite inside their lower counterparts, the opposite of normal.

We can remedy this by stimulating more bone growth along the midline suture before it fuses, resulting in a wider maxilla. We do this by installing a palatal expander, an appliance that incrementally widens the suture to encourage bone formation in the gap, which over time will widen the jaw.

An expander is a metal device with “legs” extending out on both sides and whose ends fit along the inside of the teeth. A gear mechanism in the center extends the legs to push against the teeth on both sides of the jaw. Each day the patient or caregiver uses a key to give the gear a quarter turn to extend the legs a little more and widen the suture gap. We remove the expander once the jaw widens to the appropriate distance.

A palatal expander is an effective, cost-efficient way to improve a bite caused by a narrow jaw, but only if attempted before the bones fuse. Widening the jaw after fusion requires surgery to separate the bones — a much more involved and expensive process.

To make sure your child is on the right track with their bite be sure to see an orthodontist for an evaluation around age 6. Doing so will make it easier to intervene at the proper time with treatments like a palatal expander, and perhaps correct bite problems before they become more expensive to treat.

GetAheadofBiteProblemswithInterceptiveOrthodontics

At any given time some 4 million teens and pre-teens are wearing braces or other orthodontic appliances to correct a malocclusion (poor bite). While most cases are straightforward, some have difficulties that increase treatment time and cost.

But what if you could reduce some of these difficulties before they fully develop? We often can through interceptive orthodontics.

This growing concept involves early orthodontic treatment around 6 to 10 years of age with the goal of guiding the development of a child’s jaws and other mouth structures in the right direction. These early years are often the only time of life when many of these treatments will work.

For example, widening the roof of the mouth (the palate) in an abnormally narrow upper jaw takes advantage of a gap in the bone in the center of the palate that doesn’t fuse until later in adolescence. A device called a palatal expander exerts outward pressure on the back teeth to influence the jawbone to grow out. New bone fills in the gap to permanently expand the jaw.

In cases with a developing overbite (the upper front teeth extending too far over the lower teeth when closed), we can install a hinged device called a Herbst appliance to the jaws in the back of the mouth. The hinge mechanism coaxes the lower jaw to develop further forward, which may help avoid more extensive and expensive jaw surgery later.

Interceptive treatments can also be fairly simple in design like a space retainer, but still have a tremendous impact on bite development. A space maintainer is often used when a primary (“baby”) tooth is lost prematurely, which allows other teeth to drift into the empty space and crowd out the incoming permanent tooth. The wire loop device is placed within the open space to prevent drift and preserve the space for the permanent tooth.

To take advantage of these treatments, it’s best to have your child’s bite evaluated early. Professional organizations like the American Association of Orthodontists (AAO) recommend a screening by age 7. While it may reveal no abnormalities at all, it could also provide the first signs of an emerging problem. With interceptive orthodontics we may be able to correct them now or make them less of a problem for the future.
