You’ve invested a lot of time and money in orthodontic treatment to improve your smile. If you’re not careful, though, your teeth could actually move back to their old positions. The reason why is related to the same natural tooth-moving mechanism we use to straighten teeth in the first place.
Teeth are held in place by an elastic, fibrous tissue called the periodontal ligament lying between the teeth and the jawbone and attaching to both with tiny collagen fibers. The periodontal ligament allows for incremental tooth movement in response to pressure generated around the teeth, as when we chew (or while wearing braces).
Unfortunately, this process can work in reverse. Out of a kind of “muscle memory,” the teeth can revert to the older positions once there’s no more pressure from the removed braces. You could eventually be right back where you started.
To avoid this, we have to employ measures to hold or “retain” the teeth in their new positions for some time after the braces come off. That’s why we have you wear a dental appliance called a retainer, which maintains tooth position to prevent a relapse. Depending on what’s best for your situation, this could be a removable retainer or one that’s fixed to the teeth.
Patients typically wear a retainer around the clock in the immediate period after braces, and then eventually taper off to just nighttime wear. Younger patients must wear one for several months until the new teeth positions become more secure and the chances of a rebound diminish. For older patients who’ve matured past the jaw development stage, though, wearing a retainer may be a permanent necessity to protect their smile.
Retainer wear can be an annoyance, but it’s an absolute necessity. Think of it as insurance on your investment in a new, more attractive smile.

A lot of time and effort goes into straightening your smile. But there’s a possibility it might not stay that way—and all that hard work could be lost. The same natural mechanism that enables your teeth to move with braces could cause them to revert to their old, undesirable positions.
So for a little while (or longer for some people) you’ll need to wear a retainer, an appliance designed to keep or “retain” your teeth where they are now. And while the removable type is perhaps the best known, there’s at least one other choice you might want to consider: a bonded retainer.
Just as its name implies, this retainer consists of a thin metal wire bonded to the back of the teeth with a composite material. Unlike the removable appliance, a bonded retainer is fixed and can only be removed by an orthodontist.
Bonded retainers have several advantages. Perhaps the most important one is cosmetic—unlike the removable version, others can’t see a bonded retainer since it’s hidden behind the teeth. There’s also no keeping up with it—or losing it—since it’s fixed in place, which might be helpful with some younger patients who need reminding about keeping their retainer in their mouth.
There are, however, a few disadvantages. It’s much harder to floss with a bonded retainer, which could increase the risks of dental disease. It’s also possible for it to break, in which case it will need to be repaired by an orthodontist and as soon as possible. Without it in place for any length of time the teeth could move out of alignment.
If you or a family member is about to have braces removed, you’ll soon need to make a decision on which retainer to use. We’ll discuss these options with you and help you choose the one—removable or bonded—that’s right for you.
