If you or a family member has problems with teeth alignment or your bite, you may be considering braces. This tried and true method can straighten out most smiles — but there's more to braces than you may realize.
For one thing, orthodontic treatment wouldn't work if it weren't for the natural mechanism for tooth movement that already exists in the mouth. It may seem your teeth are rigidly set in the jawbone but that's not how they maintain their attachment: that's the job of an elastic connective tissue known as the periodontal ligament that lies between the tooth and the bone. The ligament has tiny fibers that attach to the tooth on one side and to the bone on the other to actually hold the teeth in place, much like a hammock secured between two posts.
The ligament attachment also allows the teeth to move incrementally in response to environmental factors or the aging process. We harness this natural movement ability with braces to move teeth to a more desirable position. We first attach small brackets to the front crowns of the teeth (the visible portion) and then string arch wires through them. We then attach the wires to anchor points where we can adjust the amount of tension they're exerting through the brackets against the teeth. By gradually increasing that tension, the teeth respond as they would when any force is applied against them and begin to move.
By precisely controlling that movement we can transform a patient's smile. But we believe the advantages are more than cosmetic: the teeth will function better and will be easier to care for and keep clean. These benefits, though, have to be balanced with heightened risks for root resorption (something that occurs only about 10% of the time) in which the ends of the roots can shrink, or loss of mineral content in teeth enamel where the hardware makes it more difficult to remove bacterial plaque. These risks can be reduced by closely monitoring dental health during the entire treatment process and through stepped up efforts in daily oral hygiene.
The starting point for deciding on an orthodontic treatment is a thorough dental examination with x-rays or CT scan imaging. Once we have a complete picture of your misalignment problems and any other extenuating circumstances, we can recommend a treatment plan just for you.

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.

It’s a big moment after months of wearing braces to finally get a glimpse of your new smile. The crooked teeth and poor bite are gone — and in their place are beautiful, straight teeth!
If you’re not careful, though, your new look might not last. That’s because the natural mechanism we used to straighten your teeth may try to return them to their previous poor positions.
Contrary to what many people think, teeth aren’t rigidly set within the jaw bone. Instead, an elastic, fibrous tissue known as the periodontal ligament lies between the teeth and the bone and attaches to both with tiny fibers. Though quite secure, the attachment allows the teeth to move in very minute increments in response to growth or other changes in the mouth.
Orthodontic appliances like braces or clear aligners put pressure on the teeth in the direction we wish them to move. The bone dissolves on the side of the teeth where pressure is being applied or facing the direction of movement and then builds up on the other side where tension is occurring.
The ligament, though, has a kind of “muscle memory” for the teeth’s original position. Unless it’s prevented, this “memory” will pull the teeth back to where they used to be. All the time and effort involved with wearing braces will be lost.
That’s why it’s important for you to wear an appliance called a retainer after your braces have been removed. As the name implies, the appliance “retains” the teeth in their new position until it’s more permanently set. For most people, this means wearing it for twenty-four hours in the beginning, then later only a few hours a day or while you sleep.
The majority of younger patients eventually won’t need to wear a retainer once bone and facial growth has solidified their teeth’s new position. Older adults, though, may need to wear one from now on. Even so, it’s a relatively slight inconvenience to protect that beautiful, hard-won smile.
