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. 

Retainers keep your smile in place when active treatment is complete and adults need to wear their retainers for life, but adolescents may be able to stop wearing them after about 10 years.

Multiple types of retainers exist, including these:

These are plates that sit on the roof of the mouth, and wires wrap around the front of the teeth to keep the plates in place. You can remove these retainers when you eat, or you may only wear them at night.
These retainers look a little like aligners. They wrap all the way around the teeth. Similarly, you remove them when you eat, or you might only wear them when you sleep.

These retainers sit behind the teeth, so they're not visible. But they never come out. You've probably heard of traditional and plastic retainers before. But permanent retainers might seem a little unusual to you.

Retainers keep your smile in place when active treatment is complete and adults need to wear their retainers for life, but adolescents may be able to stop wearing them after about 10 years.

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 met these criteria:

  • 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 the following:

The wire can come loose and poke and prod your teeth.
You can't push floss between your teeth while wearing a permanent retainer. The wire blocks access. It's also hard for dentists to clean between your teeth when you're wearing a retainer like this.
Permanent retainers can rub on the tongue, and the chafing can be incredibly uncomfortable.

Wearing Retainers After Braces

Retainers aren’t just something you wear after you get your braces off. They’re part of your orthodontic treatment. Braces have moved your teeth into their ideal positions, and a retainer will keep them there (“retaining” your corrected smile and bite). 

If you don’t wear your retainer after completing your treatment, your teeth may move or “shift” back to their old position, or to new incorrect positions. This can erase all of the work and time you’ve put into wearing and caring for your braces.

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.

How Long Do You Have to Wear a Retainer

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 positions. 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 chances of teeth shifting are 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 clear teeth 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 do the following:

Remove Them
Take out the device when you're preparing to eat or when you're going to drink something other than water.
Clean Them
Nasty buildup can make your device both look and taste bad. A brushing under cool water can help you keep the retainer clean.
Protect Them
Keep your retainer in a case when it's not in your mouth. It's very easy to forget these devices and throw them away.
Replace Them

If the devices feel loose or worn, or if they are cracked or damaged, you'll need a new retainer.

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 products 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 spots, 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.

Retainer Treatment Timeline Frequently Asked Questions

How long do you have to wear a retainer after braces?
Your orthodontist will likely instruct you to wear your retainer full time (only removing to eat and perform your daily hygiene routine) for four to six months immediately after braces treatment. To ensure your teeth stay in place, you may have to wear your retainer on a part-time basis for months, years, or even the rest of your life.
Can I stop wearing my retainer after 6 months?
While many individuals will not need to wear a retainer on a full-time basis after 6 months, part-time retainer use will be needed to ensure teeth don’t shift or migrate over time.
How many years do you have to wear a retainer?
How long you’ll have to wear your retainer after braces depends on your teeth and your treatment plan. Some people may only have to wear a retainer for a few months. Others may have to wear a retainer part-time indefinitely.
How long can I skip wearing my retainer?
To ensure your teeth don’t have a chance to move back from their corrected positions, it’s important not to skip wearing your retainer. Skipping wearing your retainer once or twice isn’t likely to cause problems, but repeatedly not wearing the retainer as advised could allow for teeth to shift significantly.
