It’s been a long road with your braces, but now they’re finally off. Hopefully the first glimpse of your new smile more than made up for the time and effort they required.
But while braces removal is a big milestone, it’s not the end of your treatment—not, that is, if you want to keep that new smile! You’ll now need to wear an appliance called a retainer for a few years or, in some cases, from now on.
Orthodontic retainers are a must after braces for the same reason braces work in the first place—your teeth can move. While the teeth attach to the jawbone via the roots, they’re firmly held in place by an elastic gum tissue network called the periodontal ligament. This tough but elastic tissue lies between the teeth and gums and attaches securely to both with tiny fibers.
While the ligament provides stability, it’s also dynamic—constantly remodeling to allow the teeth to move in response to biting pressure and other mouth factors. Orthodontists use this mechanism when moving teeth to better positions. The braces apply pressure on the teeth in the desired direction and the periodontal ligament responds as the teeth move.
Afterward, however, the ligament can still retain a kind of “muscle memory” for a time of the teeth’s old positions. Free of the pressure once supplied by the braces the teeth have a tendency, especially early on, to “rebound” to where they were.
A retainer helps prevent this by exerting just enough pressure to “retain” the teeth in their new positions. In the beginning this may require wearing the appliance around the clock, but you may be able later to reduce wear time to just a few hours a day. Rebounding is unpredictable, so you should continue to follow your orthodontist’s recommendations on retainer wear.
Wearing a retainer may seem like a drag, but it’s absolutely essential. Being diligent about it will help ensure that the beautiful smile you and your orthodontist worked so hard to obtain stays with you for years to come.

After months of wearing braces, the big day has arrived — they’re finally off! Your teeth have been realigned and your smile is dazzling. You’re finished with orthodontic treatment, right?
Not quite — because if you want to keep your new smile you have one more treatment phase to go — wearing a retainer. Without this phase there’s a distinct possibility you could lose all the time, effort and expense of braces because your teeth could revert to their previous position.
To understand why, we have to consider how teeth can move in the first place. Although it may seem like your teeth are rigidly fastened to the jawbone, they’re actually held in place by the periodontal ligament, a strong, elastic gum tissue that lies between the teeth and the bone. Tiny fibers from the ligament attach to the teeth on one side and to the bone in a similar manner on the other side.
When pressure is applied to the tooth as happens with braces, the bone around the side of the tooth in the direction of the force will begin to dissolve (resorb), allowing the tooth to move in that direction. New bone will then build up on the other side to stabilize the tooth. Once the pressure is removed (when we take the braces off), there’s a tendency for the teeth, bone and gums to “remember” the old position and try to revert back.
The answer is a removable mouth appliance known as a retainer. Custom-designed to fit the teeth’s new position, the retainer helps hold the teeth in place until the bone completely sets around them. In the beginning, you may need to wear the retainer around the clock and then later only at night while you sleep. While you may only need to wear it for a few months (especially if you’re an adolescent or young adult) some patients may need to wear some form of retainer indefinitely. Your orthodontist will advise you how long depending on your individual situation.
While retainers may seem like an inconvenience, they’re extremely important for keeping or “retaining” the teeth in their new and better position. Following through on this important phase of treatment will help ensure you’ll keep your new smile for a long time to come.

Whether they come as removable devices or wires permanently attached behind the front teeth, orthodontic retainers have a crucial job to do in your mouth. Here's the skinny on what you ought to know about them.
1) Retainers keep your new smile looking the way it should.
After having braces to move your teeth into the desired position, a retainer is needed to keep them from moving right back where they were! In time, the periodontal (“peri” – around; “odont” – tooth) structures, which are constantly renewing themselves, will adapt to their new positions, and the teeth will stabilize.
2) There are different types of retainers.
Once upon a time, retainers were made of pink plastic and bent wire, and were removable. They're still available — but a common alternative today is to have clear retainers that fit onto your teeth covering them entirely or to have thin wires bonded to the inside of the front teeth They don't show, and you don't have to worry about putting them in and taking them out. If you prefer, ask us whether this type of retainer would work for you.
3) It takes several months for your teeth to become stable in a new arrangement.
Teeth must be held in position long enough for the bone and ligament that attaches them to the jaw to re-form and mature around them. A retainer helps avoid trauma as the teeth and associated structures are adjusting to relocation, allowing the process to end slowly and gently.
4) Even when they're stable, your teeth are always in a “dynamic” state.
There is some “memory” inherent in bone and gum tissue, which tends to cause teeth to shift back to their former positions for a long period of time after treatment. But teeth aren't held in place just by bone and ligament — a balance between the forces of the lips, cheeks and tongue also helps them stay put. This balance changes over a period of time.
5) The movement of teeth is unique to each person, and is not predictable.
Contrary to what orthodontists used to believe, there is no “right” position for the teeth that assures they will stay in place permanently. In time, the position of the teeth may change due to a slow “uprighting” movement of the front teeth in the lower jaw, which causes them to crowd as they move toward the tongue. Other factors may also cause a gradual movement of the teeth. But remember to always follow our recommendations; they will help keep your smile looking its best.

We'd like to take a moment to clarify why it is so important to wear the retainer(s) given to you after your orthodontic treatment. These devices, which literally “retain” your teeth in their new and improved positions, are not just for kids. Anyone who has recently had their teeth moved through orthodontics needs to wear them for the prescribed length of time. Here's why:
Though your teeth may now look perfectly aligned, research has shown that there is no “right” position for your teeth to be in that can assure they don't move again — no matter what age you are when treated for malocclusion (“mal” – bad; “occlusion” – bite). In fact, most people will see changes to their bite and tooth alignment as they get older, with or without orthodontic treatment.
For one thing, there is a natural tendency for bottom front teeth to undergo a gradual “uprighting” with age. This can cause them to crowd as they move toward the tongue. And it happens regardless of whether wisdom teeth are present.
In the case of teeth that have been straightened recently, a type of “memory” of their original position may cause them to drift back to it. This tendency gradually lessens, but it may be a problem for up to 18 months.
That's why it's crucial to follow our instructions for wearing retainers. Keep in mind that the plan we have given you is designed to achieve the best possible results in your individual case. Some people will need to wear retainers 24 hours per day, some just at night, and still others on an as-needed basis. You may have received a removable retainer or one that is secured to the back of your teeth. The important thing is to secure the results you've worked so hard to achieve.
