HaveYourChildsChronicMouthBreathingCheckedtoAvoidBiteProblems

We breathe every moment of every day and we’re hardly aware of it most of the time. But if you take the time to focus, you’ll find two possible pathways for your breath: through the nose or through the mouth.

While either pathway provides the air exchange needed to live, nose breathing offers better health benefits. Air passes through the nasal passages, which filter out many harmful particles and allergens. The mucous membranes in the nose also humidify the air and help produce heart-friendly nitric oxide.

Nose breathing also plays a role in your child’s facial and jaw development: the tongue rests on the roof of the mouth (the palate) and becomes a kind of mold around which the developing upper jaw can form. With chronic mouth breathing, however, the tongue rests just behind the lower teeth, depriving the upper jaw of its normal support. This could result in the development of a poor bite (malocclusion).

To avoid this and other undesirable outcomes, you should have your child examined if you notice them breathing mostly through the mouth, particularly at rest. Since chronic mouth breathing usually occurs because of an anatomical obstruction making nose breathing more difficult, it’s usually best to see a physician or an ear, nose and throat (ENT) specialist first for evaluation and treatment.

It’s also a good idea to obtain an orthodontic evaluation of any effects on their bite development, such as the upper jaw growing too narrowly. If caught early enough, an orthodontist can correct this with a palatal expander, a device that exerts gradual outward pressure on the jaw and stimulating it to grow wider.

Another bite problem associated with chronic mouth breathing is misalignment of the jaws when closed. An orthodontist can address this with a set of removable plates worn in the mouth. As the jaws work the angled plates force the lower jaw forward, thus encouraging it to grow in the direction that best aligns with the upper jaw.

Any efforts to correct a child’s breathing habits can pay great dividends in their overall health. It could likewise head off possible bite problems that can be both extensive and costly to treat in the future.

ToothTroublesforNBAStarIsaiahThomas

All eyes were on Boston Celtics point guard Isaiah Thomas in Game 1 of the second-round NBA Playoff series against the Washington Wizards — and not just because he scored a game-high of 33 points! Even more dramatic was the moment his jaw collided with an opponent’s elbow, sending one of his front teeth flying out of his mouth and onto the floor.

Press reports said the Celtics’ team physician attempted to reinsert the tooth, but it didn’t remain in place when Thomas resumed playing the game. Over the next several days, he reportedly underwent a total of ten hours of oral surgery, and was fitted with a four-piece temporary bridge. A statement from the team noted that Thomas suffered “a complete fractured tooth and two other subluxed/shifted teeth… [He] will receive a permanent bridge at a future date.” So what does all that mean?

When we say a tooth is fractured, it means the crown (visible part) of the tooth has broken off from its roots, either above or below the gum line. Depending on the severity of the fracture, it is sometimes possible to save the natural tooth by performing a root canal to prevent bacterial infection, and then placing a crown (cap) on the tooth to restore its appearance and function. In more severe cases, however, the tooth can’t be saved and must be extracted.

Unfortunately, that isn’t Thomas’ only problem. He also has two subluxed teeth — that is, teeth that have shifted from their original position, but haven’t been knocked out of their sockets. Subluxed teeth often result from a severe blow to the mouth, and may be treated by stabilization or splinting. Team officials haven’t said exactly what was done during Thomas’ dental treatment, but it could very well have involved extracting the roots of any teeth that couldn’t be saved, and possibly placing dental implants in his jaw for future tooth restoration.

A dental implant is a small screw-shaped titanium post that is inserted directly into the bone of the upper or lower jaw in a minor surgical procedure. In time, it becomes fused with the bone itself, offering a sturdy anchorage for replacement teeth. One implant can support one replacement crown; two or more implants can support a number of replacement teeth joined together as a unit. This is called a dental bridge.

Bridges can also be supported by adjacent healthy teeth — but first, the outer surfaces of the crown must be prepared (reduced in size), so that the bridge can be attached over the remaining part of the crown. In many instances, implants are preferred because they do not compromise the structure of healthy teeth nearby.

Dental difficulties didn’t end Isaiah Thomas’ season — but an earlier hip injury that became aggravated finally did.  As unfortunate as this is, maybe now at least the NBA star will have a chance to let those injured teeth heal, and show up next season with a smile that’s as good as new.

NewMaterialsAddStrengthtoVeneersBeautifulLife-Likeness

With exciting innovations in cosmetic dentistry over the last few decades, we can now transform nearly any unattractive smile. One of the best and most cost-effective of these is the porcelain veneer. These thin layers of dental porcelain are bonded over the front of chipped, slightly misaligned or stained teeth to create an entirely new look.

Veneers have evolved over time, especially with the materials they contain that give them their beauty and life-likeness. The first veneers were made mainly of feldspathic porcelain, a mineral composition known for its similarity in color and translucence to natural teeth.

But because this early porcelain had a high amount of silica (in essence, glass), and because they were created through overlaying several thin layers that weren’t as strong as a single piece, they were prone to shattering. This made them problematic for teeth subject to heavy biting forces or patients with clenching or grinding habits.

The situation changed dramatically in the 1990s, when dental labs began adding Leucite, a sturdier glass-like mineral that didn’t diminish the porcelain’s translucence. Not only did Leucite make veneers more shatter-resistant, it also enabled dental technicians to fashion most of the veneer in one piece to further strengthen it.

More recent veneers may now incorporate an even stronger material called lithium disilicate. Because lithium disilicate has twice the strength of Leucite, veneers made with it can be as thin as 0.3 millimeters. Not only does this blend together the most desirable qualities expected of a veneer—strength, aesthetic appeal and easy fabrication—it allows for a broader range of situations and uses.

Both of these materials can be pressed or milled to assume the exact shape necessary to fit a particular tooth. The manufacturing process also allows for creating smaller veneers that can then be overlaid with porcelain for the most life-like appearance possible.

Thanks to these stronger materials enhancing the natural beauty of porcelain, we now have a wider creative palate for transforming your smile.
