If you want to keep your teeth straight after getting your braces off, you need to wear a retainer. This device keeps your teeth in proper alignment for years to come. For best results, always follow your provider’s recommendations for wearing a retainer.
Even after braces made your teeth straight, they aren’t completely firm in their new position. This doesn’t happen until the gums, bones and muscles get used to the change. Everyday habits like chewing and grinding apply forces to your teeth and can move them. Shifting teeth can also lead to malocclusion. This is when your upper and lower teeth don’t align with your mouth closed.
Your braces kept your teeth in a straight position for a long time. Once the braces come off, nothing is keeping your teeth from moving back to their previous position. Wearing a retainer helps keep your teeth in the correct place, so they don’t move. Think of it this way: Braces straighten your teeth, but your retainer keeps them that way. They help your teeth “retain” their position.

A general dentist or an orthodontist fits you for your retainer. Orthodontists are dentists who have special training in the correct alignment of teeth.
The two main types of retainers are:
Many dental providers use a combination of fixed and permanent retainers to keep teeth straight. You could have both types at the same time. The purpose of all types of retainers is to make your alignment last for years.
Fixed retainers (also called permanent retainers) stay on your teeth with a glue-like bonding agent. You can’t remove this type of retainer yourself. These are often used on the front, lower or upper teeth to keep them from coming apart or shifting over time.
Removable retainers can go in and out of your mouth. Traditional (Hawley) retainers have a piece of wire attached to plastic (or acrylic). Clear retainers (Essix) are also plastic but don’t have any wires. Both are custom-made to fit your teeth.
The process for making the retainer for your teeth depends on which type you get.
For removable retainers:
Note: Many dental offices take digital impressions. Digital impressions are an alternative to the traditional impressions mentioned above. During this process, your dental provider simply uses a handheld wand to capture images of your teeth and gums. Next, a computer software program stitches those images together, creating a three-dimensional model of your mouth.
For fixed retainers:
When your provider takes off your braces, your teeth are perfectly aligned. Using a retainer keeps your teeth in the correct position so the results last. With the long-term use of a teeth retainer, all the hard work you put into getting and wearing braces pays off.
It’s normal for teeth to move over time. If you don’t wear your retainer, your teeth will shift and move. They can become crooked, crowded or misaligned. Or you can develop an overbite. That’s why most dental providers prescribe the use of a teeth retainer after braces come off.
When you get your retainer after your braces come off, it shouldn’t hurt. The fit should be snug yet comfortable over your teeth.
You could feel discomfort if:
If you do feel pain, it’s probably from your retainer nudging your teeth into the correct alignment. If you wear your retainer as directed by your dental provider, and it’s in good condition, you shouldn’t feel any pain or discomfort.
Your dental provider will likely recommend you wear the retainer day and night (full-time) for at least four to six months. After that, you’ll need to wear the teeth retainer at night (part-time) for the rest of your life.
If you stop wearing your retainer and your teeth move, going back to wearing the retainer might move the teeth back to their aligned position. But don’t wait too long — the more your teeth shift, the harder it is to get the retainer to fit right.
Prevent your retainer from getting damaged or lost so it’ll last a long time. You can keep it in great condition by cleaning it at least once a day.
Follow these tips so you don’t break or lose your retainer:
These guidelines can help keep your retainer clean:
Talk to your dental provider about care instructions specific to your retainer. They can show you how to clean it.
Fix a broken retainer right away. Broken wires can poke and irritate your gums or lips. There’s likely nothing you can do at home to fix your retainer. See your dentist or orthodontist if your retainer breaks.
If you can’t find your retainer, contact your dental provider to get a new one made. Don’t delay — the longer you go without wearing a retainer, the more your teeth can shift.
The typical price for a removable retainer is anywhere between $100 and $500. Clear retainers tend to cost more.
Some insurance carriers provide partial coverage for orthodontic treatment, while others don’t. Check with your insurance provider for the specifics of what your policy covers.
No, retainers don’t straighten teeth like braces do. Teeth retainers can’t apply the constant, steady force needed to move teeth into their correct positions.
If you forgot to wear your retainer for a few weeks and your teeth have shifted, wearing it may help nudge your teeth back into their correct position. You’ll probably feel some discomfort as the retainer slowly pushes your teeth back into alignment. This usually only works for subtle, short-term changes.
If your retainer is too snug or no longer fits, your teeth have probably shifted. There’s nothing you can do to make your current retainer fit. Your dental provider can adjust it or make a new retainer.
Bacteria can grow on a retainer just like it can grow inside of your mouth. The bacteria that cause bad breath can also create a nasty smell on your retainer. That’s why cleaning your retainer every day is so important. If your retainer starts to smell, scrub it with soap, water and a soft toothbrush. Ask your dental provider if you can soak it in a special cleanser made for retainers.
