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.

Undergoing regular dental cleanings is an essential part of periodontal (gum) disease prevention. While a daily habit of brushing and flossing cleans bacterial plaque from most tooth surfaces, it’s difficult to remove from places your brush or floss can’t access well. That, as well as hardened plaque deposits known as calculus, must be removed by a hygienist or dentist with a technique known as scaling.
Scaling is traditionally performed manually using specialized hand instruments known as scalers. Although hand scalers are quite effective, they must be used carefully to avoid damage to gum tissue or, during deeper cleaning known as root planing, the tooth roots. A different method for plaque removal known as ultrasonic scaling has grown in popularity as an alternative to manual scaling.
Ultrasonic scaling uses equipment emitting vibrational energy that crushes and loosens plaque and calculus, and disrupts growing bacterial colonies in biofilm. Plaque particles are then washed away using water irrigation. The most recent models of ultrasonic scalers have matched the effectiveness of hand scaling in removing plaque and calculus in shallow gum pockets, and surpassed the manual technique in cleaning out pockets greater than 4 mm. In experienced hands, they’re kinder to tooth structure and other tissues. Water irrigation also improves healing by removing bacteria and scaling by-products, which also makes the area easier to view by the hygienist.
On the other hand, any type of power scaler must be used with caution with patients who have pacemakers, and are not recommended for those with hypersensitive teeth or teeth that are in the early stages of de-mineralization. The technique may also produce an aerosol of finely misted particles (with possible contamination) that requires added measures to contain them.
For most patients, though, ultrasonic scalers are an effective tool for plaque and calculus removal. As ultrasonic devices continue to evolve, patients will ultimately benefit from greater comfort and reduced treatment times.
