In her decades-long career, renowned actress Kathy Bates has won Golden Globes, Emmys, and many other honors. Bates began acting in her twenties, but didn't achieve national recognition until she won the best actress Oscar for Misery — when she was 42 years old! “I was told early on that because of my physique and my look, I'd probably blossom more in my middle age,” she recently told Dear Doctor magazine. “[That] has certainly been true.” So if there's one lesson we can take from her success, it might be that persistence pays off.
When it comes to her smile, Kathy also recognizes the value of persistence. Now 67, the veteran actress had orthodontic treatment in her 50's to straighten her teeth. Yet she is still conscientious about wearing her retainer. “I wear a retainer every night,” she said. “I got lazy about it once, and then it was very difficult to put the retainer back in. So I was aware that the teeth really do move.”
Indeed they do. In fact, the ability to move teeth is what makes orthodontic treatment work. By applying consistent and gentle forces, the teeth can be shifted into better positions in the smile. That's called the active stage of orthodontic treatment. Once that stage is over, another begins: the retention stage. The purpose of retention is to keep that straightened smile looking as good as it did when the braces came off. And that's where the retainer comes in.
There are several different kinds of retainers, but all have the same purpose: To hold the teeth in their new positions and keep them from shifting back to where they were. We sometimes say teeth have a “memory” — not literally, but in the sense that if left alone, teeth tend to migrate back to their former locations. And if you've worn orthodontic appliances, like braces or aligners, that means right back where you started before treatment.
By holding the teeth in place, retainers help stabilize them in their new positions. They allow new bone and ligaments to re-form and mature around them, and give the gums time to remodel themselves. This process can take months to years to be complete. But you may not need to wear a retainer all the time: Often, removable retainers are worn 24 hours a day at first; later they are worn only at night. We will let you know what's best in your individual situation.
So take a tip from Kathy Bates, star of the hit TV series American Horror Story, and wear your retainer as instructed. That's the best way to keep your straight new smile from changing back to the way it was — and to keep a bad dream from coming true.

Have you heard about dental sealants? These preventive treatments have been available for many decades, and more and more children are taking advantage of them. The National Institutes of Health (NIH) estimates that around 30% of kids from 6 to 11 years of age have had sealants applied to their molars (back teeth). Sealants are designed to reduce the incidence of cavities by filling in or eliminating the pits or crevices found in all molars, where decay-causing bacteria can hide and your brush can't reach. But do they really work?
Now, the research is in, and the answer is clear — YES!
Two major studies, each of which reviewed the results of thousands of patients over several years, recently came to the same conclusion: Dental sealants are effective at reducing cavities, and their benefits can last for four years (or more) after application. In general, the studies showed that kids who didn't get sealants were twice, three times, or even more likely to get cavities, compared to kids treated with sealants.
Sealants themselves are protective coatings made of plastic resins or glass-like materials. They are applied in liquid form, and then hardened by a special light. When “painted on” to the chewing surface of a molar, sealants fill in the tiny crevices, or “pits and fissures,” that are found there. Uneven tooth surfaces form a perfect breeding ground for the bacteria that cause tooth decay; worse yet, the bristles of a tooth brush can't usually reach them. That's what makes these areas highly susceptible to tooth decay.
Applying sealants is a quick and painless procedure that doesn't require any numbing shots or drilling. Many kids start getting sealants when the first permanent molars come in, around age 5 to 7; they may have more sealant treatments when additional molars emerge, between the ages of 11 and 14.
Sealants are recommended by the American Dental Association and the American Academy of Pediatric Dentistry, and have only a modest cost per tooth. On the other hand, having a cavity filled generally costs substantially more, and may result in more trouble (and expense) down the line — so sealants can make sense economically, as well as preventively. This is especially true for those at high risk for tooth decay.
