There are many new and exciting ways now to transform an unattractive smile into one you'll be confident to display. But not all “smile makeover” techniques are new — one in particular has been around for generations: using braces to correct crooked teeth.
Braces have improved the smiles (and also dental health) for millions of people. But as commonplace this orthodontic treatment is, it wouldn't work at all if a natural mechanism for moving teeth didn't already exist. Braces “partner” with this mechanism to move teeth to better positions.
The jawbone doesn't actually hold teeth in place — that's the job of an elastic gum tissue between the teeth and bone called the periodontal ligament. Tiny fibers extending from the ligament attach to the teeth on one side and to the bone on the other. In addition to securing them, the dynamic, moldable nature of the ligament allows teeth to move incrementally in response to forces applied against them.
To us, the teeth feel quite stationary (if they don't, that's a problem!). That's because there's sufficient length of the tooth roots that are surrounded by bone, periodontal ligament and gum tissue. But when pressure is applied against the teeth, the periodontal ligament forms both osteoblasts (bone-forming cells) and osteoclasts (bone-resorbing cells) causing the bone to remodel. This allows the teeth to move to a new position.
Braces take advantage of this in a controlled manner. The orthodontist bonds brackets to the outside face of the teeth through which they pass a thin metal wire. They attach the ends of the wire to the brackets (braces), usually on the back teeth. By using the tension placed in the wire, the orthodontist can control the gradual movement of teeth to achieve proper function and aesthetics. The orthodontist continues to monitor the treatment progress, while making periodic adjustments to the tension.
It takes time, but through this marvelous interplay between nature and dental science you'll gain a more healthy and beautiful smile.

You’ve been concerned for some time about your child’s bite, so you’ve visited an orthodontist for an evaluation. Even though your child is quite young and still with primary teeth, the orthodontist recommends they begin wearing a retainer device, with the possibility of braces in a few years.
That may at first sound like an overly extensive treatment plan. For certain bite problems, however, undergoing an early stage of orthodontic treatment could reduce or even eliminate the need for more advanced and costly treatment later.
An example of such a problem is a crossbite, also known as an underbite. With this type of malocclusion (bad bite) the lower front teeth bite in front of the upper front teeth rather than behind them as in a normal bite relationship. Because the teeth and jaws are still in development (including the primary teeth, which are preparing the path for the permanent teeth erupting later), wearing a retainer device could exert just enough pressure to influence the teeth toward a better alignment.
In essence, the goal of early orthodontic treatment is to intercept a bite problem ahead of time and prevent it from becoming a more serious one later. If early treatment isn’t undertaken or delayed until after the eruption of the permanent teeth, it will be much more difficult, if not impossible, to correct the malocclusion. Even if the initial treatment doesn’t correct the problem it could at least lessen its severity so that future treatment like braces or clear aligners can correct it with less difficulty and cost.
By getting an early start on bite problems, you’ll increase the chances your child will achieve an optimum bite when they reach adulthood. Not only will this enhance their appearance, it will greatly benefit their overall health and mouth function. In these cases, early orthodontic treatment could make all the difference in the world.

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.
