GetAheadofaDevelopingCross-BitewithThisEarlyInterventionMeasure

Applying braces or clear aligners to move misaligned teeth is only part of an orthodontist's overall mission to eliminate poor bites (malocclusions). Sometimes a malocclusion isn't caused by the teeth at all—the size of the jaw is the problem!

One type in particular, a cross-bite, often happens because the upper jaw has developed too narrowly. As a result, many of the upper teeth fit inside the lower, the opposite of normal. But a tool called a palatal expander can alleviate the problem if it's applied at an early enough age.

The device works because the upper jawbone initially forms as two halves that fit together along a center line in the roof of the mouth (the palate) running from the back of the mouth to the front. These two bone halves remain separate during childhood to facilitate jaw growth, but eventually fuse around puberty.

Consisting of two sets of wire arms joined together by a hinge mechanism in the middle, the expander device is positioned up against the palate. The orthodontist extends each arm to press against the inside of the back teeth, then adds more outward pressure by turning the mechanism in the middle with a small key. During wear, the patient or caregiver will turn the mechanism in the same way to keep up the pressure on the two sides of the jaw.

This continual pressure keeps the two bones moving away from each other and maintaining a center gap between them. In response, more bone forms on the two halves to fill the gap. In time, the newly formed bone should widen the jaw enough to correct any developing malocclusion.

Timing is everything with a palatal expander—if not used before the jaw bones fuse, the patient will need a surgical procedure to separate the bones to pursue treatment. To catch the problem early enough, children should have an orthodontic evaluation on or before they turn six. An orthodontist may be able to identify this or other emerging bite problems and intervene before it becomes worse. Taking this approach can help save you and your child more expensive orthodontic treatment down the road.

EarlyOrthodonticTechniquesCouldStopGrowingBiteProblems

The longer many health problems go on, the worse they become. Treating them as early as possible could stop or slow their development.

That holds true for poor bites: while we can certainly correct them later in life, it's often better to "intercept" the problem during childhood. Interceptive orthodontics attempts to do this with treatments that influence how the jaws and other mouth structures develop during childhood. Many of these techniques are usually best implemented before puberty.

For example, some very complex problems called cross bites can occur if the upper jaw grows too narrowly. We might be able to stop this from happening by using an orthodontic appliance called a palatal expander during the childhood years. It works because the bone at the center of the palate (roof of the mouth) has a gap running back to front until the early teens when the gap closes.

We fit the palatal expander up under and against the palate, then extend out metal arms from a center mechanism to the back of the upper teeth that exert outward pressure on them. This widens the center gap, which the body continually fills with bone as the device gradually exerts more pressure. Over time this causes the jaw to widen and lessens the cross bite. Timing, though, is everything: it's most effective before the gap closes.

Another way to aid jaw growth is a Herbst appliance, a hinged device that alters the movement of the jaws. As a child wears it, a Herbst appliance draws the lower jaw forward to develop more in that direction. Like the palatal expander, it's best used before significant jaw growth occurs.

These are just two examples of techniques and tools that can guide structural growth and prevent bite problems. Because they're most effective in the early years of oral development, your child should undergo an orthodontic evaluation as early as age 6 to see if they need and can benefit from an interceptive treatment.

Interceptive orthodontics can stop or at least slow a growing bite problem. The effort and expense now could save you much more of both later on.

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.

EarlyInterventioncanCorrectAbnormalUpperJawandPalateGrowth

Poor bites, also known as “malocclusions,” can have a dramatic impact on mouth function and appearance. Moving teeth to better positions will solve most of these bite problems — but not all.

A case in point is a malformed maxilla, the skeletal structure formed by the union of the upper jaw and the roof of the mouth (the palate). If the rear portion of the maxilla develops too narrowly, the back teeth will bite abnormally inside the lower teeth while the front teeth bite normally, creating what’s known as a crossbite. People with this kind of malocclusion often shift their lower jaw to one side to bite down completely.

This can be corrected without too much intervention if the problem is diagnosed while the person is young. This is because the maxilla is actually formed from two bones that don’t completely fuse together in the center of the palate until just after puberty. An orthodontic appliance known as a palatal expander takes advantage of this slight gap. The metal appliance is placed along the narrowed portion of the palate in the rear of the mouth: four metal “arms,” two on each side, attach to the inside of the back teeth with a tension device between them that extends the arms outward to put pressure against the teeth.

Every day the patient or a parent uses a special key to turn the tension device and cause it to expand slightly, placing additional outward pressure on the jaw. This will widen the gap in the center of the palate and new bone will grow to fill in the increased space. Over time this will cause the rear portion of maxilla to widen.

While effective, a palatal expander may not work in every case, and it must be done before the two bones fuse permanently. When it can be used, though, it’s a proven treatment that can restore proper bite function, as well as improve your child’s smile.

WhyemBigBangTheoryemActressMayimBialikCouldntHaveBraces

Mayim Bialik has spent a good part of her life in front of TV cameras: first as the child star of the hit comedy series Blossom, and more recently as Sheldon Cooper’s love interest — a nerdy neuroscientist — on The Big Bang Theory. (In between, she actually earned a PhD in neuroscience from UCLA…but that’s another story.) As a child, Bialik had a serious overbite — but with all her time on camera, braces were just not an option.

“I never had braces,” she recently told Dear Doctor – Dentistry & Oral Health magazine. “I was on TV at the time, and there weren’t a lot of creative solutions for kids who were on TV.” Instead, her orthodontist managed to straighten her teeth using retainers and headgear worn only at night.

Today, there are several virtually invisible options available to fix orthodontic issues — and you don’t have to be a child star to take advantage of them. In fact, both children and adults can benefit from these unobtrusive appliances.

Tooth colored braces are just like traditional metal braces, with one big difference: The brackets attached to teeth are made from a ceramic material that blends in with the natural color of teeth. All that’s visible is the thin archwire that runs horizontally across the teeth — and from a distance it’s hard to notice. Celebs like Tom Cruise and Faith Hill opted for this type of appliance.

Clear aligners are custom-made plastic trays that fit over the teeth. Each one, worn for about two weeks, moves the teeth just a bit; after several months, you’ll see a big change for the better in your smile. Best of all, clear aligners are virtually impossible to notice while you’re wearing them — which you’ll need to do for 22 hours each day. But you can remove them to eat, or for special occasions. Zac Efron and Katherine Heigl, among others, chose to wear clear aligners.

Lingual braces really are invisible. That’s because they go behind your teeth (on the tongue side), where they can’t be seen; otherwise they are similar to traditional metal braces. Lingual braces are placed on teeth differently, and wearing them often takes some getting used to at first. But those trade-offs are worth it for plenty of people. Which celebs wore lingual braces? Rumor has it that the list includes some top models, a well-known pop singer, and at least one British royal.

So what’s the best way to straighten your teeth and keep the orthodontic appliances unnoticeable? Just ask us! We’d be happy to help you choose the option that’s just right for you. You’ll get an individualized evaluation, a solution that fits your lifestyle — and a great-looking smile!
