While crooked teeth are usually responsible for a malocclusion (poor bite), the root cause could go deeper: a malformed maxilla, a composite structure composed of the upper jaw and palate. If that’s the case, it will take more than braces to correct the bite.
The maxilla actually begins as two bones that fit together along a center line in the roof of the mouth called the midline suture, running back to front in the mouth. The suture remains open in young children to allow for jaw growth, but eventually fuses during adolescence.
Problems arise, though, when these bones don’t fully develop. This can cause the jaw to become too narrow and lead to crowding among the erupting teeth and a compromised airway that can lead to obstructive sleep apnea. This can create a cross-bite where the upper back teeth bite inside their lower counterparts, the opposite of normal.
We can remedy this by stimulating more bone growth along the midline suture before it fuses, resulting in a wider maxilla. We do this by installing a palatal expander, an appliance that incrementally widens the suture to encourage bone formation in the gap, which over time will widen the jaw.
An expander is a metal device with “legs” extending out on both sides and whose ends fit along the inside of the teeth. A gear mechanism in the center extends the legs to push against the teeth on both sides of the jaw. Each day the patient or caregiver uses a key to give the gear a quarter turn to extend the legs a little more and widen the suture gap. We remove the expander once the jaw widens to the appropriate distance.
A palatal expander is an effective, cost-efficient way to improve a bite caused by a narrow jaw, but only if attempted before the bones fuse. Widening the jaw after fusion requires surgery to separate the bones — a much more involved and expensive process.
To make sure your child is on the right track with their bite be sure to see an orthodontist for an evaluation around age 6. Doing so will make it easier to intervene at the proper time with treatments like a palatal expander, and perhaps correct bite problems before they become more expensive to treat.

Canker sores, known medically as aphthous ulcers, are fairly common among people. Lasting for about a week or so, these mouth sores are usually more irritating than painful. But about a quarter of the population, especially women, frequently suffer from an acute form that doesn't often respond well to over-the-counter remedies.
A typical canker sore is usually round with a yellow-gray center ringed by a reddened "halo." They can be preceded by tingling or painful sensations at the site a few hours or so before breaking out. Recurrent aphthous stomatitis (RAS) is the more severe form of canker sore, often with outbreaks of multiple painful sores. While the more common sore is usually less than a centimeter in diameter, RAS sores are often much larger.
Canker sores often arise during periods of stress or anxiety, and seem to be connected with eating certain acidic foods like tomato sauce, citrus fruits or spicy dishes. RAS also seems to be related to underlying systemic conditions like vitamin deficiencies, anemia or digestive disorders. Besides managing diet and stress, people with regular canker sores and milder cases of RAS can often find relief with non-prescription numbing agents often found in stores and pharmacies.
For more severe RAS, though, you may need the help of your dentist or physician with treatments like prescription steroids or other medications that come in gel or rinse form or through injections. The goal of any treatment approach is to decrease pain severity and shorten healing times after an outbreak.
While most mouth sores, including RAS, aren't dangerous to your health, you should still take any sore seriously. You should especially seek medical evaluation if a sore doesn't heal after a couple of weeks, if they seem to come more frequently and are more severe, or if you don't seem to ever be without a sore in your mouth. These could indicate a serious underlying problem that needs to be addressed.
One thing's for sure: there are ways to ease your suffering if you have frequent bouts with regular canker sores or even RAS. Talk to your dentist about ways to minimize your discomfort from these irritating mouth sores.

Besides attractively showcasing your teeth, your gums protect your teeth and underlying bone from bacteria and abrasive food particles. Sometimes, though, the gums can pull back or recede from the teeth, leaving them exposed and vulnerable to damage and disease.
Here are 4 things that could contribute to gum recession—and what you can do about them.
Periodontal (gum) disease. This family of aggressive gum infections is by far the most common cause for recession. Triggered mainly by bacterial plaque, gum disease can cause the gums to detach and then recede from the teeth. To prevent gum disease, you should practice daily brushing and flossing and see your dentist at least twice a year to thoroughly remove plaque. And see your dentist as soon as possible for diagnosis and treatment at the first sign of red, swollen or bleeding gums.
Tooth position. While a tooth normally erupts surrounded by bone, sometimes it erupts out of correct alignment and is therefore outside the bony housing and protective gum tissue. Orthodontic treatment to move teeth to better positions can correct this problem, as well as stimulate the gum tissues around the involved teeth to thicken and become more resistant to recession.
Thin gum tissues. Thin gum tissues, a quality you inherit from your parents, are more susceptible to wear and tear and so more likely to recede. If you have thin gum tissues you'll need to stay on high alert for any signs of disease or problems. And you should also be mindful of our next common cause, which is….
Overaggressive hygiene. While it seems counterintuitive, brushing doesn't require a lot of "elbow grease" to remove plaque. A gentle scrubbing motion over all your tooth surfaces is usually sufficient. On the other hand, applying too much force (or brushing too often) can damage your gums over time and cause them to recede. And as we alluded to before, this is especially problematic for people with thinner gum tissues. So brush gently but thoroughly to protect your gums.
