After months of wearing braces, the big day has arrived — they’re finally off! Your teeth have been realigned and your smile is dazzling. You’re finished with orthodontic treatment, right?
Not quite — because if you want to keep your new smile you have one more treatment phase to go — wearing a retainer. Without this phase there’s a distinct possibility you could lose all the time, effort and expense of braces because your teeth could revert to their previous position.
To understand why, we have to consider how teeth can move in the first place. Although it may seem like your teeth are rigidly fastened to the jawbone, they’re actually held in place by the periodontal ligament, a strong, elastic gum tissue that lies between the teeth and the bone. Tiny fibers from the ligament attach to the teeth on one side and to the bone in a similar manner on the other side.
When pressure is applied to the tooth as happens with braces, the bone around the side of the tooth in the direction of the force will begin to dissolve (resorb), allowing the tooth to move in that direction. New bone will then build up on the other side to stabilize the tooth. Once the pressure is removed (when we take the braces off), there’s a tendency for the teeth, bone and gums to “remember” the old position and try to revert back.
The answer is a removable mouth appliance known as a retainer. Custom-designed to fit the teeth’s new position, the retainer helps hold the teeth in place until the bone completely sets around them. In the beginning, you may need to wear the retainer around the clock and then later only at night while you sleep. While you may only need to wear it for a few months (especially if you’re an adolescent or young adult) some patients may need to wear some form of retainer indefinitely. Your orthodontist will advise you how long depending on your individual situation.
While retainers may seem like an inconvenience, they’re extremely important for keeping or “retaining” the teeth in their new and better position. Following through on this important phase of treatment will help ensure you’ll keep your new smile for a long time to come.

Your diet can play as important a role in your dental health as brushing and flossing. What you eat (particularly sugar) could increase your risk of tooth decay despite your hygiene habits. And vice-versa: a nutritious diet may help boost your preventive efforts even more.
Let’s look at two very different approaches to diet and see how your dental health is likely to fare under each.
A High Sugar/Low Fiber Diet. Modern western diets heavy with processed foods are inundated with two particular types of refined sugars. The first is sucrose, which comes mainly from either beets or sugar cane. Foods (and beverages) may also contain a refined sugar from corn known as high fructose corn syrup. Refined sugars are added for taste to thousands of products like cake, candy, soft drinks or even condiments like catsup. These “free” sugars are easily processed by bacteria into acid. Combine that with fewer fibrous vegetables in the diet and you have a recipe not only for obesity and other health issues, but tooth decay as well.
A High Fiber/Low Sugar Diet. Fruits and vegetables make up a large part of this kind of diet, while added free sugars much less so. That doesn’t make this diet sugar-free: all plant products contain simple sugars produced by photosynthesis. The difference, though, is that these sugars — glucose, fructose and sucrose (natural, not the refined versions) — are more slowly absorbed into the bloodstream during digestion because of the fiber content of fruits and vegetables. You’ll also receive other nutrients like vitamins and minerals necessary for good health. Eating this kind of diet will help decrease the risk of tooth decay.
So there you have it: eat more fresh fruits and vegetables and restrict your intake of processed foods and sweets. You may also want to fine-tune a few items to maximize decay prevention: for example, eat starches in their natural form (whole grains, beans or certain fruits) as much as possible rather than refined or in combination with added sugar (cakes, cookies, etc.). And while fresh fruits with their naturally occurring sugars aren’t a significant factor in tooth decay, dried fruits (especially with added sugar) might.
