Breathing: You hardly notice it unless you're consciously focused on it—or something's stopping it!
So, take a few seconds and pay attention to your breathing. Then ask yourself this question—are you breathing through your nose, or through your mouth? Unless we're exerting ourselves or have a nasal obstruction, we normally breathe through the nose. This is as nature intended it: The nasal passages act as a filter to remove allergens and other fine particles.
Some people, though, tend to breathe primarily through their mouths even when they're at rest or asleep. And for children, not only do they lose out on the filtering benefit of breathing through the nose, mouth breathing could affect their dental development.
People tend to breathe through their mouths if it's become uncomfortable to breathe through their noses, often because of swollen tonsils or adenoids pressing against the nasal cavity or chronic sinus congestion. Children born with a small band of tissue called a tongue or lip tie can also have difficulty closing the lips or keeping the tongue on the roof of the mouth, both of which encourage mouth breathing.
Chronic mouth breathing can also disrupt children's jaw development. The tongue normally rests against the roof of the mouth while breathing through the nose, which allows it to serve as a mold for the growing upper jaw and teeth to form around. Because the tongue can't be in this position during mouth breathing, it can disrupt normal jaw development and lead to a poor bite.
If you suspect your child chronically breathes through his or her mouth, your dentist may refer you to an ear, nose and throat (ENT) specialist to check for obstructions. In some cases, surgical procedures to remove the tonsils or adenoids may be necessary.
If there already appears to be problems brewing with the bite, your child may need orthodontic treatment. One example would be a palatal expander, a device that fits below the palate to put pressure on the upper jaw to grow outwardly if it appears to be developing too narrowly.
The main focus, though, is to treat or remove whatever may be causing this tendency to breathe through the mouth. Doing so will help improve a child's ongoing dental development.

Every year many parents learn their “tweenager” or teenager needs their bite corrected, often with specialized orthodontics. Imagine, though, if these families could go back in time to when their child’s poor bite was just developing to stop or slow it from forming.
Time travel may still be science fiction, but the approach suggested isn’t. It’s called interceptive orthodontics, a group of techniques and procedures performed during the early stages of jaw development. The focus is usually on getting abnormal jaw growth back on track, enough so that a poor bite won’t form.
The upper jaw, for example, may be growing too narrow, reducing the amount of available space for tooth eruption. If it isn’t corrected, teeth can erupt out of position. To correct it, an orthodontist places a palatal expander in the roof of the child’s mouth (palate). The appliance applies gentle pressure against the inside of the teeth, which stimulates the jaws to develop wider.
The expander works because of a separation in the bones at the center of the palate, which later fuse around puberty. The pressure applied from the expander keeps this gap slightly open; the body then continues to fill the widening expansion with bone, enough over time to widen the jaw. If you wait until puberty, the gap has already fused, and it would have to be reopened surgically to use this technique. Ideally, then, a palatal expander should be employed at a young age.
Not all interceptive techniques are this extensive—some, like a space maintainer, are quite simple. If a primary (baby) tooth is lost prematurely, teeth next to the empty space tend to drift into it and cause the intended permanent tooth to erupt out of place due to a lack of space. To prevent this an orthodontist places a small wire loop within the space to prevent other teeth from moving into it.
These are but two examples of the many methods for stopping or slowing a developing bite problem. To achieve the best outcome, they need to be well-timed. Be sure, then, to have your child undergo an orthodontic evaluation around age 6. If an interceptive orthodontic approach is needed, it could eliminate the need for more extensive—and expensive—treatment later.
Fans of the legendary rock band Steely Dan received some sad news a few months ago: Co-founder Walter Becker died unexpectedly at the age of 67. The cause of his death was an aggressive form of esophageal cancer. This disease, which is related to oral cancer, may not get as much attention as some others. Yet Becker's name is the latest addition to the list of well-known people whose lives it has cut short—including actor Humphrey Bogart, writer Christopher Hitchens, and TV personality Richard Dawson.
As its name implies, esophageal cancer affects the esophagus: the long, hollow tube that joins the throat to the stomach. Solid and liquid foods taken into the mouth pass through this tube on their way through the digestive system. Worldwide, it is the sixth most common cause of cancer deaths.
Like oral cancer, esophageal cancer generally does not produce obvious symptoms in its early stages. As a result, by the time these diseases are discovered, both types of cancer are most often in their later stages, and often prove difficult to treat successfully. Another similarity is that dentists can play an important role in oral and esophageal cancer detection.
Many people see dentists more often than any other health care professionals—at recommended twice-yearly checkups, for example. During routine examinations, we check the mouth, tongue, neck and throat for possible signs of oral cancer. These may include lumps, swellings, discolorations, and other abnormalities—which, fortunately, are most often harmless. Other symptoms, including persistent coughing or hoarseness, difficulty swallowing, and unexplained weight loss, are common to both oral and esophageal cancer. Chest pain, worsening heartburn or indigestion and gastroesophageal reflux disease (GERD) can also alert us to the possibility of esophageal cancer.
Cancer may be a scary subject—but early detection and treatment can offer many people the best possible outcome. If you have questions about oral or esophageal cancer, call our office or schedule a consultation. You can learn more in the Dear Doctor magazine article “Oral Cancer.”
