What is a retainer?
A dental retainer is a device that fits over or behind your teeth to keep them in position. These appliances are most often used after treatment with braces.
Retaining devices can be made from clear plastic, metal wire, or a combination of the two. The different retainer types function in slightly different ways, but they have the same purpose.
What does a retainer do?
Let’s be honest, wearing braces isn’t something you do for fun. You’ve worked hard and probably endured some discomfort to get a smile you’re happier with. The last thing you want is for your teeth to start moving out of position again. That’s where your teeth retainer comes in.
After your braces have been removed, your teeth will naturally start moving back to their original position. It’s also common for our teeth to shift as we get older and when wisdom teeth come through. Wearing a retainer after braces helps to hold your teeth in the correct alignment.
Both removable and permanent retainers will keep your teeth straight for years to come, as long as you keep wearing them as your dentist advises!
You can get a retaining device for the upper or lower teeth only, or for both – usually corresponding to where your braces were placed.
Braces vs. retainers: What’s the difference?
Braces are designed to move misaligned teeth into a better position to improve dental health. They can be fixed onto your teeth with brackets, or you can use removable aligner braces like Invisalign. Treatment with braces can last anywhere between 6 months and 3 years, depending on the amount of movement required.
Retaining devices are worn after braces and are usually intended to keep your teeth straight rather than move them. There are many different types: permanent or removable, plastic or metal, but they all have the same goal: to stop your teeth from becoming crooked again.
Can retainers straighten teeth?
Some mouth retainers can straighten crooked teeth if only mild correction is needed. For example, if you have previously worn braces and your teeth have started moving again. Your dentist or orthodontist will be able to advise you if this is an option for you.
Spring retainers, or spring aligners, can help with simple movements of the teeth. They look similar to a normal Hawley retainer, for teeth but they have extra parts that move one or more teeth slightly or help to prevent the teeth from overcrowding or twisting.
Invisalign is one popular type of clear aligner, but if you’re looking at cheap retainers for teeth, we’re guessing you don’t have a huge budget. In that case, at-home aligners like Candid could be a good option. Candid, at around just $2,000 is much more affordable than Invisalign, but they don't sacrifice quality of treatment. We recommend Candid because your treatment is monitored exclusively with specialist orthodontists, and they include advanced AI technology as part of your treatment, that helps your orthodontist speed up treatment time and make it more effective.
In cases where teeth are severely misaligned, Invisalign (like Vivera) or traditional braces might be more effective.

While they may look similar, retainers, mouth guards, and night guards are all used for different reasons. Retainers are what help keep your teeth in position after orthodontic care, while mouthguards are designed to keep the teeth safe from injury. Mouthguards are made of flexible plastic that protects the jaw and teeth during physical activity and sports. Alternatively, night guards are more firm than a mouthguard and made for patients that clench or grind their teeth at night. Nightguards protect the teeth and jaw from pain and damage caused by the grinding.

Types of retainers: Permanent retainer vs. removable
As we’ve mentioned, there are a few different types of teeth retaining devices available. We’ll give you some information about their plus points and downsides and show you what each retaining device looks like, but you should listen to your dentist's advice about what’s best for your teeth.
Hawley retainers, also called wire or metal retainers, can be used on both your upper and lower teeth. They are fully removable and you should take them out for eating and drinking sugary drinks. The plate (the part that touches your gums and palette) is made from acrylic plastic, and there are wires that sit over and across your teeth. Some dentists might offer to customize the retainer color or add a pattern.
This is one of the cheapest options available and they can last for many years if cared for properly. One obvious downside of Hawley retainers is that they are very noticeable, especially if used on the upper teeth. Once you transition to only wearing them at night, though, this isn’t such an issue.
You may also hear a Hawley device called a ‘wrap-around retainer', but it’s different from some braces treatments that need a headpiece. As mentioned earlier, spring retainers can be added to offer minor teeth straightening.
If you want a clear retaining device that is removable then an Essix retainer could be suitable. This is formed to completely cover your teeth and sit above your gum line.
Some people prefer this type because they are less noticeable than wire retainers. Essix retainer costs are similar to the Hawley style, but they may not last as long.
You’ll need to remove your device for eating and clean it regularly. It might become discolored over time, but you can prevent this with a proper cleaning routine – more on this later. If you want to know more about this option, read our full Essix retainer article here.
This is the clear, plastic retainer for teeth from the manufacturers of the Invisalign retainer (sometimes called Invisalign braces). It is made from super strong material so it’s less likely to break than other plastic devices.
To get one fitted, a laser scan is taken of your mouth, so if you don’t like the feeling of teeth impressions being taken, this could be a great option. You don’t have to have had Invisalign to get one of these.
A completely different option is a permanent bonded retainer. Also called lingual or fixed, this type is only used on the front six teeth, often just as a bottom retainer on the lower jaw. A strong wire is glued behind the teeth, permanently retaining the shape you achieved with braces. You may find yourself replacing yours every 3-10 years.
Permanent retainers cost a little more than basic removable ones, but the fact that they are completely hidden is a plus for many people.
While there’s no chance of losing this type of device, having the wire fixed to your teeth does make it difficult to clean and floss properly.
How much does a retainer cost?
Teeth retainers cost anywhere from $100 to $500 per set without insurance. Depending on your dentist, orthodontic retainer costs can vary quite a bit. The cost can also depend on location, and what type you are recommended to use. Here’s a rough guide to how much different dentist retainers cost with a private dentist:
Note that prices are for a single device, except for Vivera Invisalign retainers which come in a set of 4.
Follow-up treatment or checks may be needed after you have your appliance fitted, so make sure you check whether this is included in the retainers price. There are other factors to consider as well; the cost of a removable retainer may be lower than the cost of a permanent one. However, how often will you have to replace them?
Can you buy retainers online?
Yes, you can buy a replacement retainer online if you can't get to a dentist or want to save money on in-office retainer prices. There are various online services that send you an impression kit which you use to make a mold of your teeth at home. Send this off, and soon you'll receive your clear retainers in the mail.
While you can find this online service available for multiple types of retainers, it's best to go to the orthodontist or dentist, or company with whom you completed treatment, as this will facilitate the process of getting your new retainer.
What does Medicaid cover?
Children under 18 in families below a certain income level are entitled to free dental treatment, either from Medicaid or from the Children's Health Insurance Program (CHIP). This applies to orthodontic treatment and orthodontic retaining devices, as long as the work is deemed medically necessary. The only thing that may not be covered is the cost to replace a retaining device that’s lost or broken beyond repair, which can cost anywhere from $70 to $500, depending on whether it's an individual or a set.
Generally speaking, Medicaid will not cover treatment for:
- Slightly protruding teeth
- Minor misalignments that don’t affect function
- Over- or under-bites where you can still use teeth normally
- Anything that won’t cause future health problems
Our guide to Medicaid and Medicare explains more about what's covered by Medicaid depending on what state you live in.
How much is a replacement retainer?
Whether or not you or your child qualify for a free replacement retaining device depends on your insurance and the state you live in. To find out if you or your child can get a replacement retainer for free, call the number on the back of your health insurance card.
With a private dentist, a retainer replacement often costs the same as the original. There might be some savings if you don't need new dental impressions for your retainer replacements.
Damaged devices can sometimes be fixed. If yours has been damaged or broken, seek advice from your dentist.
It’s worth noting, Vivera retainers cost more but come in a set of three or four. This means that if you lose your device, or break it, you can just switch to one of the others rather than having to rush to the dentist.
How long do you have to wear a retainer after braces?
Your teeth will slowly move throughout your life, especially if you had your braces before your wisdom teeth grew in. It’s quite common for people to notice their teeth have moved after braces, years after receiving orthodontic treatment. To make sure your teeth stay straight, you should be prepared to wear an orthodontic retaining device for the rest of your life.
If you have a removable retainer, you’ll probably be asked to wear it nearly all of the time for the first six months, except while eating of course! After that, you can normally start to wear your device only overnight. Your dentist will instruct you on how long to wear your teeth retainer each day according to your treatment.
By its very nature, a permanent retainer stays in place the whole time. You don’t have to remember anything except your normal cleaning routine – a plus if you are worried you might forget to put your device in each day or night.
In the following video, an orthodontist describes the importance of wearing a retainer after braces:
How to clean your retainer
Cleaning your device is just as important as cleaning your teeth. Otherwise, food debris can get stuck and encourage plaque and bacteria to build up, increasing the risk of tooth decay and gum disease and creating bad odors. Clear retainers will also become discolored if you don’t clean them properly.
Removable and permanent retainers need different types of care, possibly including the use of a special cleaner. Your dentist will show you the best ways to clean, but here are some guidelines.
You can follow these simple steps for the best way to clean plastic retainers as well as metal ones:
- Rinse your device with warm water after removal and before putting it back in.
- Clean it twice a day with dish soap or castile soap. You can use a soft-bristled brush to gently scrub, Hawly retainers, but using a brush on Essix and Vivera retainers isn't recommended.
- Some dentists recommend soaking your device in a retainer cleaning product like Retainer Brite. Follow your dentist’s advice and the instructions on the product packaging of the cleaner.
- To clean clear retainers that have turned yellow, gently scrub using baking soda, water, and a soft toothbrush.
- Never use whitening toothpaste on your Vivera, Hawley or Essix retainer! It can be too rough and abrasive, so stick to soap and water.
You can learn more about Retainer Brite and how to clean your device by reading our full retainer cleaning guide.
How to clean permanent retainers
Bonded retainers can’t be removed for cleaning, so the process is different. It might take a little getting used to but it will be part of your daily routine in no time.
Dental floss or interdental brushes are vital to maintaining your dental health when you have fixed retainers behind your teeth. If you use floss you will need to use a threader to pass it between your teeth, under the bonded wire. Interdental brushes may make it easier to get to any plaque build-up; have a try and see what works best for you. Of course, you should still brush your teeth as normal too.
How to fix a cracked retainer
Cracked retainer? Even with excellent care, your retainer, permanent or removable, will probably break at some point. If you're wondering how to fix a broken retainer at home, unfortunately you can't. In order to ensure safe and effective retaining, you need to go to your orthodontist or dentist to have it fixed (or order a replacement retainer online if you go through an online service).
There are several different types of retainers you can wear after braces, but they all have the same aim: to keep your teeth in position after they have been straightened.
Whether you decide to get a permanent retainer or a removable Hawley or Essix retainer, the important thing is to follow your dentist’s instructions for using it properly. They will tell you how long to wear your device each day and how to clean it properly so it lasts as long as possible.
It's also possible to get retainer braces that provide mild correction, but if teeth straightening is your main concern, you should probably consider clear aligners instead. For an affordable and convenient at-home option, find out if you're eligible for Candid with their Smile Assessment now.
Teeth Retainer FAQs
Do retainers hurt?
Retaining devices can hurt sometimes, but usually just for a day or two after fitting. The retainer pain should not be really bad and you can take your usual painkillers to manage this type of pain. If it continues or gets worse you should go to the dentist as soon as possible.
Forgetting to put your retainer in for a few days can make wearing a retainer painful. This is because your teeth have already started to move slightly and you're forcing them back into place.
If parts of the retainer are irritating your tongue, cheeks or gums, mention it to your dentist. Often, this is easily solved by using a nail file to remove any sharp edges.
Can I keep my teeth straight without a retainer?
The short answer is, no. It’s completely normal for your teeth to move over time and this movement can be unpredictable. To guarantee your time with braces was worth it, you will need to keep wearing your appliance forever.
What’s the best retainer after braces?
It is important to wear a plastic or wire retainer after braces, but which one is best for you depends on what your dentist advises. There are a few factors to consider, such as cost, how easy they are to keep clean, how noticeable they are, and whether you are prone to losing things!
You may be offered a choice of metal vs. clear retainers, and there are positive and negative points about each. Weigh your options, but remember that a removable one can easily be changed if you don’t like it. Ask your dentist what they recommend for you, and why.
Why do my retainers smell bad?
Your device is exposed to all the food, plaque and bacteria in your mouth so – just like your mouth – it will start to smell if you don't clean it properly. Soak it in a specially designed cleaning product like Retainer Brite every couple of days to keep smells and stains at bay. After each cleaning, make sure you store it in the retainer case with the lid open until it dries.
How much do retainers cost?
The retainer cost can be anywhere from $100 to $500 give or take a bit on either end. The cheapest retainers for teeth are usually Hawley retainers with Essix, Vivera and lingual retainers costing more. Vivera retainers can cost up to $1,000, but that's because you have to purchase a set of four.
How long do you wear retainers?
Most orthodontists instruct patients to wear retainers full-time for the first few months after you get your braces off, and then let you switch to nighttime wear indefinitely. If you have a permanent retainer, you don't have to worry about that, because you'll be wearing it all of the time.
What happens if you don't wear your retainer?
If you don't wear your retainer, your teeth will begin to shift back to their original original position, also called a relapse. This can begin to happen even if you don't wear your retainer for a couple of days, which is why you may notice that it is a bit too snug or uncomfortable. If your retainer fits without being painful, you can resume wearing it. However, if the retainer doesn't fit without being painful, you'll need to visit your orthodontist.
How long do retainers last?
Permanent retainers can last indefinitely, although top bonded retainers generally fail after three years. Bonded bottom teeth retainers can last much longer due to less daily wear and tear. Hawley retainers can last for anywhere from 1 to 20 years, depending on how well you care for yours, and plastic clear retainers can last for a couple of years at most.
Why do my teeth hurt when I wear my retainer?
If your teeth hurt when you wear your retainer, as yourself how many days have gone by since the last time you wore it. Retainers hurting teeth is something that happens when teeth begin to shift back to their original position, also known as relapse. And if you're wondering how to make your retainer fit again, there's no safe or effective way to do that without visiting your dentist or orthodontist for an adjustment or a new retainer altogether.
