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.

Straightening your smile doesn't happen overnight—it can involve months or even years of orthodontic treatment. And although the end result is well worth it, the long process can make it difficult to keep your gums healthy, especially while wearing braces.
Gum swelling in particular is a common problem for braces wearers with two potential sources. First, orthodontic hardware makes it difficult to keep teeth clean of dental plaque, a thin bacterial film that can cause gum disease. Plaque and its hardened counterpart tartar can trigger a gum infection, which in turn triggers inflammation. As a result, affected gums appear swollen and red, and can easily bleed.
Gum tissues may also react to braces pressing against them and develop hypertrophy (or hyperplasia), an increase in individual tissue cell growth. If this overgrowth occurs, it may not get resolved until after your braces have been removed.
As long as the hypertrophy doesn't appear to have weakened gum attachment with the teeth, it's usually not a big concern. But what is a concern is that hypertrophy could increase a braces wearer's difficulties with oral hygiene and give rise to a true gum infection that could endanger dental attachment. Advanced cases could require surgical correction or removal of the braces altogether to adequately treat the infection.
The best way to avoid a worst case scenario is to be as diligent as possible with daily brushing and flossing. Fortunately, there are several tools that can make it easier with braces. Interproximal brushes, tiny brushes that can fit into the narrow spaces between the teeth and the braces, can be used in conjunction with your regular toothbrush.
Flossing is also easier if you use a floss threader or a water flosser. The latter utilizes a pump to emit a pulsating jet of water to break loose plaque between teeth and flush it away. Clinical studies have shown the effectiveness of water flossers for removing plaque in braces wearers as opposed to not flossing at all.
A faithful daily hygiene practice and twice-a-year cleanings and checkups with your regular dentist can help minimize your chances of gum swelling. Doing so will help ensure you'll complete your orthodontic treatment on the way to healthier and more attractive smile.

Around ages 6 to 8, a child's primary teeth will begin to loosen to make way for their permanent teeth. If all goes well, the new set will come in straight with the upper teeth slightly overlapping the bottom.
But sometimes it doesn't go that well: a child may instead develop a poor bite (malocclusion) that interferes with normal function. If we can detect the early signs of a developing malocclusion, however, we may be able to intervene and lessen its impact. You as a parent can play a vital role in this early detection.
The first thing you should be watching for is teeth spacing.Â Normal teeth come in straight with a slight gap between them. But there are two abnormal extremes to look for: teeth having no space between them or crowded together in a crooked, haphazard manner; or they seem to have too much space between them, which indicates a possible discrepancy between the teeth and jaw sizes.
You should also notice how the teeth come together or “bite.” If you notice the lower front teeth biting in front of the upper (the opposite of normal) it may be a developing underbite. If you see a space between the upper and lower teeth when they bite down, this is a sign of an open bite. Or, if the upper front teeth seem to come down too far over the lower, this could mean a deep bite: in extreme cases the lower teeth actually bite into the roof of the mouth behind the upper teeth.
You should also look for crossbites, in which the teeth in one part of the mouth bite abnormally in front or behind their counterparts, while teeth in other parts bite normally. For example, you might notice if the back upper teeth bite inside the lower teeth (abnormal), while the front upper teeth bite outside the lower front teeth (normal).
The important thing is to note anything that doesn't look right or seems inconsistent with how your child's teeth look or how they function. Even if you aren't sure it's an issue, contact us anyway for an examination. If it really is a developing bite problem, starting treatment now may lessen the extent and cost of treatment later.
