You can't correct a poor bite with braces or clear aligners overnight: Even the most cut-and-dried case can still require a few years to move teeth where they should be. It's a welcome relief, then, when you're finally done with braces or aligner trays.
That doesn't mean, however, that you're finished with orthodontic treatment. You now move into the next phase—protecting your new smile that took so much to gain. At least for a couple of more years you'll need to regularly wear an orthodontic retainer.
The name of this custom-made device explains its purpose: to keep or “retain” your teeth in their new, modified positions. This is necessary because the same mechanism that allows us to move teeth in the first place can work in reverse.
That mechanism centers around a tough but elastic tissue called the periodontal ligament. Although it primarily holds teeth in place, the ligament also allows for tiny, gradual tooth movement in response to mouth changes. Braces or aligner trays take advantage of this ability by exerting pressure on the teeth in the direction of intended movement. The periodontal ligament and nature do the rest.
But once we relieve the pressure when we remove the braces or aligners, a kind of “muscle memory” in the ligament can come into play, causing the teeth to move back to where they originally were. If we don't inhibit this reaction, all the time and effort put into orthodontic treatment can be lost.
Retainers, either the removable type or one fixed in place behind the teeth, gently “push” or “pull” against the teeth (depending on which type) just enough to halt any reversing movement. Initially, a patient will need to wear their retainer around the clock. After a while, wear time can be reduced to just a few hours a day, usually during sleep-time.
Most younger patients will only need to wear a retainer for a few years. Adults who undergo teeth-straightening later in life, however, may need to wear a retainer indefinitely. Even so, a few hours of wear every day is a small price to pay to protect your beautiful straightened smile.

If you think periodontal (gum) disease is something that only happens to the other guy (or gal), you might want to reconsider. Roughly half of adults over age 30—and nearly three-quarters over 65—have had some form of gum disease.
Gum disease isn't some minor inconvenience: If not treated early, a gum infection could lead to bone and tooth loss. Because it's inflammatory in nature, it may also impact the rest of your health, making you more susceptible to diabetes, heart disease or stroke.
Gum disease mainly begins with dental plaque, a thin film of food particles on tooth surfaces. Plaque's most notable feature, though, is as a haven for oral bacteria that can infect the gums. These bacteria use plaque as a food source, which in turn fuels their multiplication. So, the greater the plaque buildup, the higher your risk for a gum infection.
The best way to lower that risk is to reduce the population of bacteria that cause gum disease. You can do this by keeping plaque from building up by brushing and flossing every day. It's important for this to be a daily habit—missing a few days of brushing and flossing is enough for an infection to occur.
You can further reduce your disease risk by having us clean your teeth regularly. Even if you're highly proficient with daily hygiene, it's still possible to miss some plaque deposits, which can calcify over time and turn into a hardened form called tartar (or calculus). Tartar is nearly impossible to remove with brushing and flossing, but can be with special dental tools and techniques.
Even with the most diligent care, there's still a minimal risk for gum disease, especially as you get older. So, always be on the lookout for red, swollen or bleeding gums. If you see anything abnormal like this, see us as soon as possible. The sooner we diagnose and begin treating a gum infection, the better your chances it won't ultimately harm your dental health.
