You can't correct a poor bite with braces or clear aligners overnight: Even the most cut-and-dried case can still require a few years to move teeth where they should be. It's a welcome relief, then, when you're finally done with braces or aligner trays.
That doesn't mean, however, that you're finished with orthodontic treatment. You now move into the next phase—protecting your new smile that took so much to gain. At least for a couple of more years you'll need to regularly wear an orthodontic retainer.
The name of this custom-made device explains its purpose: to keep or “retain” your teeth in their new, modified positions. This is necessary because the same mechanism that allows us to move teeth in the first place can work in reverse.
That mechanism centers around a tough but elastic tissue called the periodontal ligament. Although it primarily holds teeth in place, the ligament also allows for tiny, gradual tooth movement in response to mouth changes. Braces or aligner trays take advantage of this ability by exerting pressure on the teeth in the direction of intended movement. The periodontal ligament and nature do the rest.
But once we relieve the pressure when we remove the braces or aligners, a kind of “muscle memory” in the ligament can come into play, causing the teeth to move back to where they originally were. If we don't inhibit this reaction, all the time and effort put into orthodontic treatment can be lost.
Retainers, either the removable type or one fixed in place behind the teeth, gently “push” or “pull” against the teeth (depending on which type) just enough to halt any reversing movement. Initially, a patient will need to wear their retainer around the clock. After a while, wear time can be reduced to just a few hours a day, usually during sleep-time.
Most younger patients will only need to wear a retainer for a few years. Adults who undergo teeth-straightening later in life, however, may need to wear a retainer indefinitely. Even so, a few hours of wear every day is a small price to pay to protect your beautiful straightened smile.

The straightening process for a crooked smile doesn't end when the braces come off. There's one more crucial phase to undergo to make sure we don't lose the progress you've achieved: wearing an orthodontic retainer.
Although often viewed as a nuisance, retainers are important because they prevent realigned teeth from reverting to their old positions. This is possible because the periodontal ligament, the gum attachment that allows us to move teeth in the first place, can contain “muscle memory” that naturally tries to draw teeth back to where they once were.
A retainer prevents this from happening: During wear the subtle pressure they exert keeps or “retains” the teeth in their new positions until they're firmly established, usually after several months. While most patients initially wear a retainer around the clock, this will gradually taper off until they're worn primarily during sleep hours.
While retainers come in many different styles and sizes, most fall into one of two categories: removable or non-removable (bonded). The first type, a custom-made appliance a patient can easily take in and out of the mouth, has its advantages. Removing it makes it easier to clean the teeth. They're also adaptable to reduced wear schedules for eating, brushing and flossing, or for special occasions.
But a removable retainer may be noticeable to others. Its removability can also lead to problems. Out of the mouth they're prone to be lost, resulting in additional replacement costs. And immature patients may be easily tempted to take them out too often—or not wear them at all.
A bonded retainer solves many of these potential problems. Because the retainer wire is securely bonded to the back of the teeth, it's not visible to others. And because it can't be removed except by an orthodontist, there's virtually no chance of losing it or haphazard wear.
On the other hand, bonded retainers can occasionally break, requiring repair or replacement. And flossing is more difficult than with a removable retainer, although a little training from a dental hygienist can make that easier.
The choice of retainer depends on the individual and their priorities. But whether removable or bonded, a retainer is absolutely essential for protecting your new, hard-earned smile.

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.
