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.

Although it’s a natural part of dental development, teething is no picnic for your baby. This process in which each of their twenty primary teeth gradually erupt through the gums usually begins around their sixth to ninth month and may not end until around age three.
These periodic tooth eruptions can cause your baby to bite, gnaw, drool or rub their ears. Teething can also disrupt sleeping patterns, decrease appetite and cause gum swelling and pain that can turn your otherwise happy baby into an unhappy one.
Managing these teething episodes is one of the most common topics parents bring up with their dentists. Since teething is supposed to happen, there’s no need for medical intervention unless the child is also experiencing diarrhea, rashes, fever or prolonged irritability associated with teething episodes. In most cases, the best you can do is to make your child more comfortable. Here are a few things to help you do just that.
Provide cold items for gnawing. Rubber teething rings, wet wash cloths or pacifiers that have been chilled can give your child something to gnaw on and ease the pressure of sore gums while the chilled temperatures help numb pain. Be sure, though, that the items aren’t frozen because extremely cold temperatures can burn the skin.
Gum massage. You can massage your child’s gums with one of your fingers during a teething episode to counteract the throbbing pressure coming from the erupting tooth. Just be sure your finger is clean and don’t use any numbing agents unless advised by your dentist or pediatrician.
OTC medication. You can ease mild to moderate teething pain with over-the-counter pain relievers like acetaminophen or ibuprofen in dosages appropriate for your child’s age. But don’t apply rubbing alcohol to the gums or massage in any pain reliever—both practices can burn the skin. And, as mentioned before, only apply numbing agents like Benzocaine with the advice and supervision of a healthcare professional.
Besides these practices, be sure to keep up regular dental checkups to monitor the teething process and ensure all is going normally. And remember: though it may seem harrowing at times, the teething process won’t last forever.
