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.

Finally: Your braces are off! Break out the taffy, bubble gum, corn on the cob... and... whoa!!... the retainer?
Yes, the retainer. As the name implies, this simple device will ensure that your pearly whites remain in the new, desired position you've worked so diligently to achieve. Here's why:
The same physiological properties that allow your teeth to move when you're wearing braces are always at work — braces simply direct that movability in controlled ways. Teeth are not set into your jaw bone like posts fixed in concrete; rather, the root portion is attached to the bone by elastic periodontal (peri – around; odont – tooth) ligaments that permit micromovement of teeth all the time. The periodontal tissues are living; therefore, they are always changing and “remodeling” (just as hair grows, skin peels, etc.) When a light orthodontic force is placed on a tooth the following processes occur:
- on the pulling or tension side, the periodontal ligament will activate bone-forming cells (osteoblasts) to deposit new bone to fill in the area from where the tooth was previously, and
- on the pressure side, the periodontal ligament will activate bone-resorbing cells (osteoclasts) to remove bone allowing the tooth to move in that direction.
Visualize drawing your hand forward through water: The water parts in front of your hand and fills in behind it.
Once your teeth are in their desired position and your braces are removed, your teeth will tend to return to their old position if they are not stabilized or “retained” in their new one long enough for the bone and ligament to re-form and mature around them. This can take several months. In addition, orthodontic treatment stretches collagen fibers in gum tissues to some extent, contributing to the forces that tend to shift teeth back in the direction from which they came. The gum tissues will continue to exert this pressure until these tissues remodel. This can take longer than the bone and ligament stabilization, as collagen cells reorganize at a much slower rate.
Types of Retainers
The type of retainer you will use, how frequently and for how long will depend on your unique situation. The most familiar type of retainer is removable and one you may not have to wear all the time, at least after the first couple of months. In cases where the retainer is going to be needed for a long-term period, a common alternative is to have thin retainer wires bonded to the inside surfaces of the front teeth so they don't show.
Considering how much time, effort, and sometimes expense is required in improving your smile, the retainer is your assurance that it was all well spent. Even people getting a comparatively simple pedicure/manicure don't leave the salon without letting the polish dry!
