How Long Do You Really Have to Wear a Retainer?

You’ll have to wear your retainer for at least 10 years after you get your braces off or finish your aligner treatment. Many people wear their retainers for the rest of their lives.

During the first three months after braces or aligners, you should wear your retainers most of the time. After that point, you can likely transition to wearing them only at night.

What are retainers?

Think of a retainer as protection. You've invested in your smile with braces or aligners. Your retainers ensure that your teeth stay in the right place.

Multiple types of retainers exist, including:

What is a permanent retainer?

A permanent retainer is glued to the back of your teeth. Your orthodontist installs it, and it never comes out unless someone else removes it and dissolves the glue.

Experts say permanent retainers are typically recommended for people who had teeth that were:

• Very rotated.
• Crowded.
• Spaced far apart.

Teeth like this are very tempted to take up their old positions, and they need the constant presence of a retainer to keep them in line and in place.

A permanent retainer may also be recommended for people who struggle to follow instructions. You can't take it out, so you're not tempted to take a break from it. If you know you won't wear a removable retainer as instructed, a permanent version may be smart.

But permanent retainers also come with some serious drawbacks, experts say. They include:

Do you have to wear them for life?

Whether you choose a permanent retainer or a removable version, that appliance will be part of your routine for at least 10 years, if not the rest of your life.

Braces and aligners work by applying consistent pressure that stretches the network of tissues that connect your teeth to your jaws. The bones in your teeth remodel and change shape based on that pressure. But some spring in the tissues remains.

The first two weeks are critical. When constant pressure is removed, teeth are tempted to take up their old positions. During this time, you'll wear your retainer all the time to protect your investment.

But even when those weeks pass, you'll need to entice your teeth to keep their new position. It's best to wear your retainer at night, every night, to protect your teeth. But if you had your dental work done when you were a teenager, and you wore your retainer for 10 years after treatment, you may be able to stop wearing the device, if your dentist approves.

If you had your teeth adjusted as an adult, you'll wear your retainer for life. Your chance of a tooth shift is simply greater, and teeth tend to move as we age. To protect your investment, your retainer should be part of your life moving forward.

How Many Hours Per Day Should You Wear a Retainer?

If you recently finished a treatment regime with braces or aligners, the first two weeks following treatment are critical. During this time, you may need to wear your retainer for up to 22 hours per day, taking them out only to eat and care for your teeth.

After about two weeks, you can generally transition to wearing your retainers only at night, while you sleep.

How Many Days Per Week?

You’ll need to wear your retainers every day. While missing a day or night here and there won’t cause dramatic issues, it’s important to make them part of your regular routine.

Take care of your removable retainers.

Retainers you can pop in your mouth and remove again are easy to wear and clean. But they're also easy to neglect, and doing so could come with serious consequences.

To take care of your retainers, you must:

Retainers aren't cheap. Researchers say a standard, wire retainer can cost up to $340. Some companies offer a retainer as part of your treatment package. But replacement tools usually come with a price tag.

Take care of your retainers, and they're likely to keep your smile as gleaming as possible. If you notice that your teeth keep moving, despite wearing your retainers, a conversation with your dental team is appropriate.

You might need a new retainer that keeps your teeth in the right spot, or you might need to wear your retainers for longer each day. Your team can tell you more about what you need to do.

What Happens if You Don’t Wear Your Retainer?

If you don’t wear your retainer, your teeth will eventually shift back to their old positions. This is particularly true in the months and even years directly following treatment with aligners or braces.

After you have consistently worn your retainers for at least 10 years, your teeth might be fixed in their new positions. But if they begin to shift again, you’ll need to return to regularly wearing your retainer.

Many people, particularly those who have braces or aligners in adulthood, need to wear their retainers for the rest of their lives.
