HeadOffaCrossbiteatthePassWithThisOrthodonticAppliance

At what age should you begin treating a poor bite? Many might say with braces around late childhood or early adolescence. But some bite problems could be addressed earlier—with the possibility of avoiding future orthodontic treatment.

A crossbite is a good example. In a normal bite, all of the upper teeth slightly cover the lower when the jaws are shut. But a crossbite occurs when some of the lower teeth, particularly in back, overlap the upper teeth. This situation often happens when the upper jaw develops too narrowly.

But one feature of a child's mouth structure provides an opportunity to intervene and alter jaw development. During a child's early years, the palate (roof of the mouth) consists of two bones next to each other with an open seam running between them. This seam, which runs through the center of the mouth from front to back, will fuse during puberty to form one continuous palatal bone.

An orthodontist can take advantage of this separation if the jaw isn't growing wide enough with a unique device called a palatal expander. This particular oral appliance consists of four, thin metal legs connected to a central mechanism. The orthodontist places the expander against the palate and then uses the mechanism to extend the legs firmly against the back of the teeth on both sides of the jaw.

The outward pressure exerted by the legs also widens the seam between the two palatal bones. The body will respond to this by adding new bone to the existing palatal bones to fill in the widened gap. At regular intervals, the patient or a caregiver will operate the mechanism with a key that will continue to widen the gap between the bones, causing more expansion of the palatal bones until the jaw has grown to a normal width.

The palatal expander is most effective when it's applied early enough to develop more bone before the seam closes. That's why it's important for children to undergo bite evaluation with an orthodontist around age 6. If it appears a bite problem is developing, early interventions like a palatal expander could slow or stop it before it gets worse.

WhatToDoAboutWhiteSpotsonTeethAfterWearingBraces

The big day finally arrives when your braces come off. And there it is—your new, beautiful, straight smile! But on closer inspection you notice something else: tiny white spots on your teeth.

Those pale, chalky spots are called white spot lesions (WSLs). They occur when acid has contacted the tooth enamel for too long, dissolving essential minerals like calcium in those particular areas. The occurrences of WSLs during and after braces highlights a major challenge during orthodontic treatment—keeping your teeth clean.

Braces' wires and brackets tend to get in the way of brushing and flossing, making it easier to miss plaque—the bacterial film that produces acid—on tooth areas around the hardware. Those missed areas could in time lead to WSLs.

The main objective with WSLs is prevent them from occurring during braces wear as much as possible. To do this, you'll need to increase your time and effort brushing and flossing, especially around orthodontic hardware. You can make it easier, though, by using a few tools that often work better than regular toothbrushes and floss like interproximal toothbrushes, power brushes, floss threaders or water flossers.

You can also help lower your mouth's acidity by avoiding or limiting acidic foods and beverages, including juices, sodas, sports and energy drinks. And, by all means, keep up your regular dental cleaning schedule with your general dentist.

Should WSLs develop while you're wearing braces, don't panic. It's possible they'll diminish on their own, or at least not worsen. We can also foster re-mineralization of the enamel with applied fluoride, short bursts of laser light or a procedure called microabrasion that restores damaged areas below the enamel surface.

For more resistant WSLs, we can also inject a liquid tooth-colored resin into them that when hardened by a curing light can make those areas look translucent like normal enamel. We can also use other cosmetic solutions like bonding or veneers to improve your teeth's appearance.

Like other dental problems, dealing with a WSL is usually more successful if caught and treated early. So, check your teeth often while wearing braces, and if you notice anything unusual don't hesitate to call your dentist.

6SignsYourChildCouldBeDevelopingaPoorBite

If your child has seen the dentist regularly, and brushed and flossed daily, there's a good chance they've avoided advanced tooth decay. But another problem might already be growing right under your nose—a poor dental bite (malocclusion).

A dental bite refers to the way the upper and lower teeth fit together. In a normal bite the teeth are in straight alignment, and the upper teeth slightly extend in front of and over the lower when the jaws are shut. But permanent teeth erupting out of position or a jaw developing abnormally can set the stage for a malocclusion.

Although the full effects of a malocclusion may not manifest until later, there may be signs of its development as early as age 6. If so, it may be possible to identify a budding bite problem and “intercept” it before it goes too far, correcting it or reducing its severity.

Here are 6 signs your school-age child could be developing a malocclusion.

Excessive spacing. If the spacing between teeth seems too wide, it could mean the size of your child's teeth are out of proportion with their jaw.

Underbite. Rather than the normal upper front teeth covering the lower, the lower teeth extend out and over the upper teeth.

Open bite. There's a space or gap between the upper and lower teeth even when the jaws are shut.

Crowding. Due to a lack of space on the jaw, incoming teeth don't have enough room to erupt and may come in misaligned or “crooked.”

Crossbites. Some of the lower teeth, either in front or back of the jaw, overlap the upper teeth, while the rest of the upper teeth overlap normally.

Protrusion or retrusion. This occurs if the upper front teeth or jaw appear too far forward (protrusion) or the lower teeth or jaw are positioned too far back (retrusion).

Besides watching out for the preceding signs yourself, it's also a good idea to have your child undergo a comprehensive bite evaluation with an orthodontist around age 6. If that does reveal something amiss with their bite, intervention now could correct or lessen the problem and future treatment efforts later.

ThisOrthodonticDeviceCouldStopaPoorBiteFromDeveloping

“Orthodontic treatment” and “braces” almost seem like synonymous terms. But while braces certainly are orthodontic, it isn't the only tool in an orthodontist's toolkit.

A good example is a device is known as a Herbst appliance. It's used in situations where the upper jaw is outpacing the growth and development of the lower jaw during childhood. If not corrected, this could cause the top teeth to protrude abnormally beyond the lower teeth.

The Herbst appliance gently and gradually coaxes the lower jaw to grow in a more forward direction, thus “catching up” with the upper jaw. The top part of the device consists of two metal tubes hinged to small elastic bands, which are cemented to the cheek side of the upper back teeth (molars), one on either side of the jaw.

Two smaller tubes are attached in like fashion to the lower teeth, and then inserted into the larger tubes. As the lower jaw moves, the smaller tubes move within the larger to create pressure that gently pushes the jaw forward. Over time, this can sync the growth progress of both the upper and lower jaws, and reduce the chances of a poor bite.

For best results, a Herbst appliance is usually placed to coincide with a child's most rapid period of jaw growth, usually between 11 and 14. They could be placed as early as 8 or 9, however, in situations where the front teeth are already protruding well beyond the lips. In any event, the goal is to positively influence the growth of the lower jaw to alleviate or at least minimize the need for future orthodontic treatment.

As a fixed device, there's no need for a child or parent to tend to it as with other methods, like orthodontic headwear worn in conjunction with braces. A Herbst appliance can, however, alter the normal sensations associated with eating, swallowing and speaking, which may take a little adjustment time for the child. Wearers will also need to be extra vigilant with daily brushing and flossing because of a higher risk of tooth decay.

These, though, are minor inconveniences compared with the benefit of improved bite development. As such, a Herbst appliance could be a positive investment in your child's dental future.

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.
