There are an assortment of techniques and treatments in an orthodontist's toolkit, braces being the most common and best known. Of course, there wouldn't be any tools at all if teeth couldn't move naturally.
Teeth aren't directly connected to the jawbone. An elastic tissue called the periodontal ligament lies between each one, with tiny fibers attaching to the tooth on one side and to the bone on the other. The ligament's elasticity and other qualities allow micro-movements of the teeth as we bite.
The ligament can also adapt to changes in the mouth and teeth by allowing the teeth to move to different positions. That's the basic concept behind braces: we thread a thin wire through brackets attached to the teeth, which we then attach to anchor points (usually back teeth not intended to move) and apply tension to it. Gradually over time, the target teeth move.
But what if your malocclusion (poor bite) is more complicated or the back teeth can't supply enough anchorage for moving the intended teeth? That's where we take advantage of other sources of anchorage.
One such source is the patient's skull, which we can make use of through special headgear worn a few hours a day. The device consists of a strap under tension that runs around the back of the head or neck to a wire housing attached to brackets on the target teeth. If you want to “pull” the teeth forward, the strap would come over the chin, forehead or a combination of both.
We may sometimes want to isolate some teeth to move without moving nearby teeth, such as moving front teeth backward to close a space without affecting teeth further to the rear. We can create a separate anchor point in the jaw with a TAD or temporary anchorage device.
TADs are tiny screws made of stainless steel inserted temporarily into the bone. We loop an elastic band over the TAD on one end and to a bracket or tension wire attached to the target teeth on the other. When we've achieved the teeth's new position we can easily remove the TAD from the bone.
These various tools make it possible to correct difficult or complex malocclusions. They may not always look attractive, but they'll help ensure the final result is.

There’s a potential threat lurking in your young child’s mouth—tooth decay. This destructive disease can not only rob them of teeth now, it could also impact their dental health long into their adult years.
That’s why we focus heavily on decay prevention measures even in primary (“baby”) teeth, as well as early treatment should it still occur. It’s a straightforward treatment strategy: minimize the factors that contribute to disease and maximize those that protect against it.
We can represent the disease-causing factors with the acronym BAD. Bad bacteria top the list: they produce oral acid that erodes tooth enamel. Couple that with an Absence of healthy saliva function, necessary for acid neutralization, and you have the potential opening for tooth decay. Poor Dietary habits that include too much added sugar (a prime food source for bacteria) and acidic foods help fuel the decay process.
But there are also SAFE factors that can help counteract the BAD. Promoting better Saliva function helps control acid levels, while Sealants applied to chewing surfaces strengthen these vulnerable areas against decay. We can prescribe Antimicrobials in the form of mouth rinses that reduce abnormally high bacterial concentrations. Fluoride applied directly to the enamel bolsters its mineral content. And an Effective diet high in nutrition and low in sugar or acidic foods rounds out our protective measures.
Promoting SAFE factors greatly reduces the risk of childhood tooth decay. To keep on track it’s important to start regular, six-month dental visits beginning around your child’s first birthday. These visits are the most important way to take advantage of prevention measures like sealants or topical fluoride, as well as keeping an eye out for any signs of decay.
And what you do at home is just as important. Besides providing a teeth-friendly diet, you should also brush and floss your child’s teeth every day, teaching them to do it for themselves when they’re old enough. Playing it “SAFE” with your child’s dental health will help ensure your child’s teeth stay decay-free.

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.
