Orthodontics can produce an amazing smile transformation. With today’s advanced appliances and techniques even the most difficult malocclusions (bad bites) can be overcome. All of this innovation, however, depends on one basic anatomical fact: though firmly set in the mouth, our teeth can still move.
Teeth are actually held in place by the periodontal ligament, a strong, elastic tissue that attaches to them through tiny collagen fibers on one side of the ligament and to the jawbone with similar fibers on the other side. When pressure is placed against a tooth, the bone on the opposite side of the force begins to dissolve (resorb), allowing the tooth to move. As it moves, new bone is built up behind the tooth, to stabilize it. Orthodontists take advantage of this natural mechanism through orthodontic hardware like braces that applies pressure in the desired direction of movement, while the ligament and bone do the rest.
There is, though, a downside to this process. The teeth, bone and gum tissues can contain a kind of “memory” for the former natural position of the teeth. Over time, the lower front teeth tend to take a gradual migratory movement back towards their original position. Also, as we age the lower front teeth may crowd each other as there is a genetic influence for teeth to move to the midline of the face, causing a pressure that allows the skinny lower front teeth to slip behind each other. As a result of both of these tendencies, corrected teeth may retreat from their new positions.
To stop these tendencies, we use an appliance known as a retainer after braces or other hardware is removed. As the name implies, this appliance “retains” the teeth in their new position. For structural “memory,” the retainer will keep the teeth in their new position until the impulse to return to the old one has faded, about eighteen months. Retainers can also slow or stop the natural genetic influence of movement, but it may mean wearing a retainer for an indefinite period, especially individuals who’ve undergone orthodontic treatment later in life.
The length of time you’ll need to wear a retainer after braces — and what type, whether a removable appliance or one permanently attached — will depend on a number of factors including the type of malocclusion, your individual mouth structure and age. We’ll recommend the best option that ensures the best chance of keeping your teeth in their new position.

At your child's latest dental visit, you found out one of their primary (“baby”) teeth has become decayed and in danger of loss. Of course, you may think, it's only a primary tooth — it's going to come out sooner or later.
But a primary tooth lost “sooner” rather than “later” can create long-term negative consequences for your child's dental health. For the sake of the future permanent tooth, the best treatment strategy could be to put forth the effort and expense to save it.
Besides its role in eating and chewing, a primary tooth's most important function is as a “trailblazer” for the permanent tooth developing below it. A primary tooth doesn't normally loosen and let go until the new permanent tooth is ready to erupt. Until then they hold the new tooth's space in the jaw.
But if the primary tooth is lost prematurely, nearby teeth can drift into and crowd the space so that the permanent tooth comes in out of position. This can result in a malocclusion, or poor bite.
Depending on the state of your child's jaw development, it may be advisable to attempt saving the tooth through a filling or, in the case of deep decay, a modified root canal treatment. If the tooth can't be saved, then placing an orthodontic appliance known as a space maintainer might be necessary. Cemented to a tooth next to the empty space, this appliance has a looped band of metal that butts against the tooth on the other side of the gap, and prevents both teeth from drifting into the space.
Intervening for a decayed primary tooth can seem a waste of time and money since it has a limited lifespan to begin with. But for the health of its companion permanent tooth, as well as possibly avoiding orthodontic treatment, it could be well worth it for your child's long-term dental health.

Magician Michael Grandinetti mystifies and astonishes audiences with his sleight of hand and mastery of illusion. But when he initially steps onto the stage, it’s his smile that grabs the attention. “The first thing… that an audience notices is your smile; it’s what really connects you as a person to them,” Michael told an interviewer.
He attributes his audience-pleasing smile to several years of orthodontic treatment as a teenager to straighten misaligned teeth, plus a lifetime of good oral care. “I’m so thankful that I did it,” he said about wearing orthodontic braces. “It was so beneficial. And… looking at the path I’ve chosen, it was life-changing.”
Orthodontics — the dental subspecialty focused on treating malocclusions (literally “bad bites”) — can indeed make life-changing improvements. Properly positioned teeth are integral to the aesthetics of any smile, and a smile that’s pleasing to look at boosts confidence and self-esteem and makes a terrific first impression. Studies have even linked having an attractive smile with greater professional success.
There can also be functional benefits such as improved biting/chewing and speech, and reduced strain on jaw muscles and joints. Additionally, well-aligned teeth are easier to clean and less likely to trap food particles that can lead to decay.
The Science Behind the Magic
There are more options than ever for correcting bites, but all capitalize on the fact that teeth are suspended in individual jawbone sockets by elastic periodontal ligaments that enable them to move. Orthodontic appliances (commonly called braces or clear aligners) place light, controlled forces on teeth in a calculated fashion to move them into their new desired alignment.
The “gold standard” in orthodontic treatment remains the orthodontic band for posterior (back) teeth and the bonded bracket for front teeth. Thin, flexible wires threaded through the brackets create the light forces needed for repositioning. Traditionally the brackets have been made of metal, but for those concerned about the aesthetics, they can also be made out of a clear material. Lingual braces, which are bonded to the back of teeth instead of the front, are another less visible option. The most discrete appliance is the removable clear aligner, which consists of a progression of custom-made clear trays that reposition teeth incrementally.
How’s that for a disappearing act?!

Orthodontic treatment is a big investment. But given the benefits for future good health and a more attractive smile, it's well worth it.
In the here and now, though, braces wearers face a different threat to their dental well-being — dental disease. Wearing braces can actually increase the risk of disease and make it more difficult to fight.
Tooth decay and periodontal (gum) disease, the two most common forms of dental disease, usually arise from plaque, a thin film of bacteria and food particles on tooth surfaces. The bacteria produce acid, which erodes enamel and makes the teeth susceptible to decay. Certain bacteria can also infect the gums and eventually weaken their attachment to teeth. Thorough brushing and flossing everyday removes this disease-triggering plaque buildup.
But braces' hardware can make brushing and flossing more difficult. The brackets attached to the teeth and wires laced through them make it more difficult for floss and brush bristles to access all the areas around the teeth. Plaque can build up in certain spots; it's estimated braces wearers have two to three times the plaque of a person not wearing braces. Acid can also remain in contact with some of the enamel surface for too long.
It's important, therefore, if you wear braces to make a concerted effort to brush and floss thoroughly. Besides improving technique and taking more time, you might also consider additional aids. You can obtain toothbrushes specially designed for use with braces, as well as floss holders or threaders that make it easier to access between teeth. Another flossing alternative is an oral irrigator that sprays water under pressure between teeth is an alternative to flossing.
As a precaution against acid damage, we can boost enamel protection with additional fluoride applied to your teeth. We may also prescribe antibacterial rinses to keep the bacteria population low.
Above all, be sure to look out for signs of disease like swollen or bleeding gums or pain. As soon as you sense something out of the ordinary, be sure and contact us.
