HowKathyBatesRetainsHerMovie-StarSmile

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.

AnchorageDevicesProvideMoreAccuracyLessTreatmentTimeforBraces

Braces are a common part of many teenagers’ life experience — but not every bite problem is alike. Sometimes, there’s a need for accurately moving only a few teeth while making sure others don’t. This is where Temporary Anchorage Devices (TADs) can help streamline that effort and even reduce treatment time.

Orthodontics wouldn’t work at all if we didn’t already have a natural tooth movement mechanism in our mouths. That ability rests with the periodontal ligament, a tough, elastic tissue between the teeth and the bone that firmly attaches to both with tiny collagen fibers. Though quite secure in holding teeth in place, the ligament attachment also allows teeth to move in response to changes in the bone and jaw structure.

Braces are made of brackets cemented to tooth surfaces through which tiny wires pass. The wires are anchored, usually to other teeth or groups of teeth, and tightened to apply pressure against the other teeth. The ligament does the rest: as the teeth are “pressured” to move in a certain direction, new bone, ligament and an anchoring substance known as cementum forms behind it to secure the tooth in its new position.

The anchorage teeth are not intended to move. In some situations, though, it’s difficult to keep them from not moving — much like trying to keep a boat anchor from not dragging through sand on the sea bottom. TADs help alleviate this problem: it’s a mini-screw or mini-implant that’s temporarily placed in the jawbone to which the tension wire can be secured. They’re placed in the best positions for isolating the teeth that need to be moved without compromising the position of nearby teeth that don’t.

With the site numbed with a local anesthetic, we install the TAD through the gum tissue into the bone with a special device; their screw-shaped design holds them securely in place. They’re then removed when the orthodontic treatment is complete.

While a simple procedure, precise placement requires collaboration between the orthodontist and the oral surgeon or dentist who installs them. They also need special attention during daily hygiene to keep them clean. Still, with difficult bite situations they can help bring about the right outcome — a straight and beautiful smile.
