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.

At any given time some 4 million teens and pre-teens are wearing braces or other orthodontic appliances to correct a malocclusion (poor bite). While most cases are straightforward, some have difficulties that increase treatment time and cost.
But what if you could reduce some of these difficulties before they fully develop? We often can through interceptive orthodontics.
This growing concept involves early orthodontic treatment around 6 to 10 years of age with the goal of guiding the development of a child’s jaws and other mouth structures in the right direction. These early years are often the only time of life when many of these treatments will work.
For example, widening the roof of the mouth (the palate) in an abnormally narrow upper jaw takes advantage of a gap in the bone in the center of the palate that doesn’t fuse until later in adolescence. A device called a palatal expander exerts outward pressure on the back teeth to influence the jawbone to grow out. New bone fills in the gap to permanently expand the jaw.
In cases with a developing overbite (the upper front teeth extending too far over the lower teeth when closed), we can install a hinged device called a Herbst appliance to the jaws in the back of the mouth. The hinge mechanism coaxes the lower jaw to develop further forward, which may help avoid more extensive and expensive jaw surgery later.
Interceptive treatments can also be fairly simple in design like a space retainer, but still have a tremendous impact on bite development. A space maintainer is often used when a primary (“baby”) tooth is lost prematurely, which allows other teeth to drift into the empty space and crowd out the incoming permanent tooth. The wire loop device is placed within the open space to prevent drift and preserve the space for the permanent tooth.
To take advantage of these treatments, it’s best to have your child’s bite evaluated early. Professional organizations like the American Association of Orthodontists (AAO) recommend a screening by age 7. While it may reveal no abnormalities at all, it could also provide the first signs of an emerging problem. With interceptive orthodontics we may be able to correct them now or make them less of a problem for the future.

This year's Carol Burnett Award, presented at the Golden Globes, goes to Ellen DeGeneres for her “outstanding contributions to the television medium on or off the screen.” This is the latest in a long list of honors for the comedienne, talk show host and activist that includes Emmys, Grammys and Teen Choice Awards. And one not quite as well-known: a 2004 “Flossy” award.
DeGeneres received this honor from the National Flossing Council in recognition of her passionate promotion of oral hygiene, particularly flossing. She wrote about its virtues in her 2003 book, The Funny Thing Is…., saying, among other things, “Don't even think for a second that you can get away with not flossing.”
DeGeneres's motivational cheerleading for flossing is helpful and necessary because, well, many of us just don't like doing it. It requires more manual dexterity than its more popular sibling, brushing. And the tendency for the floss to gunk up with plaque residue for some is simply unpleasant.
Mainly, though, many folks think brushing is enough. Not so fast, according to dental professionals. While brushing removes disease-causing bacterial plaque from broad tooth surfaces, it can't effectively get into the spaces between teeth. It takes flossing to clear plaque from these more difficult areas.
But don't fret: There are ways to make flossing an easier—and more pleasant—task.
Ask us for help. As we said before, flossing does take some hand dexterity and coordination to perform. You may also wonder if you're doing it effectively. We can provide training and tips on how to be a more effective flosser at your next visit.
Practice, practice, practice. You probably think nothing of riding a bicycle, and yet it probably took you weeks or months as a kid to become proficient. Similarly, your first attempts at flossing might feel awkward, but you'll improve with practice, so don't give up.
Brush before you floss. Most people floss before brushing, but if you tend to encounter a lot of soft plaque debris that makes flossing “icky” for you, then try brushing first to clear a good portion of it out of the way before you floss. Just be aware, most professionals believe that flossing first is better because it loosens up debris between teeth so the bubbles from the toothpaste can carry it away. But any flossing is better than no flossing!
Try flossing tools. For some people, floss picks, small pre-threaded tools you can use with one hand, seem easier to maneuver than regular floss thread. If you have issues with manual dexterity, an oral irrigator can make the task easier: This handheld device uses a stream of pressurized water to loosen and flush away plaque between teeth.
So, follow Ellen DeGeneres's advice she gave Tulane University graduates during a commencement speech: “Remember to exfoliate, moisturize, exercise…and floss.” The latter, along with brushing, will certainly help keep your teeth and gums healthy.
