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.

Wearing braces will probably never make your list of Most Pleasurable Life Experiences: you'll have to avoid certain foods and habits, endure some occasional discomfort, and perhaps feel some embarrassment about your appearance. The good news, though, is that at worst, these are mostly no more than inconveniences and additionally they're well worth the straighter, more attractive smile you'll achieve.
But there's one downside to braces that can lead to something more serious. The braces hardware makes brushing and flossing more difficult—and that could increase your risk of dental disease.
The principal goal of oral hygiene is to remove dental plaque, a thin film of accumulated bacteria and food particles that can cause tooth decay or periodontal (gum) disease. Without effective brushing and flossing, plaque can build up quickly and make the chances of having either of these two diseases more likely.
Not only does the braces hardware hinder your toothbrush's or floss's access to the parts of the teeth it covers, but it can also create "hiding places" for plaque build-up. Several studies have found that braces wearers on average have up to two to three times the plaque build-up of non-braces wearers.
There are ways, though, to make hygiene easier while wearing braces, particularly with flossing. Floss threaders or interproximal brushes can both be used to access between teeth while wearing braces. Another option is a water flosser or irrigator that sprays pressurized water between teeth (and beneath brackets and wires) to remove plaque. And braces wearers can get a prevention boost with topical fluoride applications or antibacterial mouth rinses to reduce disease-causing bacteria.
Besides taking a little extra time with brushing and flossing, you can also boost your mouth's health with good nutrition choices, less sugar consumption and keeping up regular dental visits. And, you should also see your dentist promptly if you notice any signs of tooth or gum problems—the sooner you have it checked and treated, the less damage any dental disease is likely to cause.
It's not easy keeping your teeth and gums plaque-free while wearing braces. But with a little extra time and effort, a few helpful tools and your dentist's support, you can maintain a healthy mouth during orthodontic treatment.
