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.
Overbites, underbites, crossbites—these are just a few of the possible malocclusions (poor bites) you or a family member might be experiencing. But no matter which one, any malocclusion can cause problems.
Besides an unattractive smile, a malocclusion makes it more difficult to chew and to keep the teeth and gums clean of disease-causing bacterial plaque. Thus correcting a malocclusion improves dental health; a more attractive smile is an added bonus.
This art of correction—moving teeth back to the positions where they belong—is the focus of a dental specialty called orthodontics. And, as it has been for several decades, the workhorse for achieving this correction is traditional braces.
Braces are an assembly of metal brackets affixed to the teeth through which the orthodontist laces a metal wire. The wire is anchored in some way (commonly to the back teeth) and then tightened to apply pressure against the teeth. Over time this constant and targeted pressure gradually moves the teeth to their new desired positions.
The reason why this procedure works is because teeth can and do move naturally. Although it may seem like they’re rigidly set within the jawbone, teeth are actually held in place by an elastic tissue network known as the periodontal ligament. The ligament lies between the tooth and bone and keeps the tooth secure through tiny fibers attached to both it and the bone. But the ligament also allows teeth to continually make micro-movements in response to changes in chewing or other environmental factors.
In a sense, braces harness this tooth-moving capability like a sail captures the wind propelling a sailboat. With the constant gentle pressure from the wires regularly adjusted by the orthodontist, the periodontal ligament does the rest. If all goes according to plan, in time the teeth will move to new positions and correct the malocclusion.
In a way, braces are the original “smile makeover”—once crooked teeth can become straight and more visually appealing. More importantly, though, correcting a poor bite improves how the mouth works, especially while eating, and keeping things clean. A straighter smile isn’t just more attractive—it’s healthier.
