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.
The basics for treating tooth decay have changed little since the father of modern dentistry Dr. G.V. Black developed them in the early 20th Century. Even though technical advances have streamlined treatment, our objectives are the same: remove any decayed material, prepare the cavity and then fill it.
This approach has endured because it works—dentists practicing it have preserved billions of teeth. But it has had one principle drawback: we often lose healthy tooth structure while removing decay. Although we preserve the tooth, its overall structure may be weaker.
But thanks to recent diagnostic and treatment advances we’re now preserving more of the tooth structure during treatment than ever before. On the diagnostic front enhanced x-ray technology and new magnification techniques are helping us find decay earlier when there’s less damaged material to remove and less risk to healthy structure.
Treating cavities has likewise improved with the increased use of air abrasion, an alternative to drilling. Emitting a concentrated stream of fine abrasive particles, air abrasion is mostly limited to treating small cavities. Even so, dentists using it say they’re removing less healthy tooth structure than with drilling.
While these current advances have already had a noticeable impact on decay treatment, there’s more to come. One in particular could dwarf every other advance with its impact: a tooth repairing itself through dentin regeneration.
This futuristic idea stems from a discovery by researchers at King’s College, London experimenting with Tideglusib, a medication for treating Alzheimer’s disease. The researchers placed tiny sponges soaked with the drug into holes drilled into mouse teeth. After a few weeks the holes had filled with dentin, produced by the teeth themselves.
Dentin regeneration isn’t new, but methods to date haven’t been able to produce enough dentin to repair a typical cavity. Tideglusib has proven more promising, and it’s already being used in clinical trials. If its development continues to progress, patients’ teeth may one day repair their own cavities without a filling.
Dr. Black’s enduring concepts continue to define tooth decay treatment. But developments now and on the horizon are transforming how we treat this disease in ways the father of modern dentistry couldn’t imagine.
