Teeth Retainers Cost, Comparison of Different Types of Retainer


After your braces come off, what next? You’ll need to wear a dental retainer if you want to your teeth to stay in their new position.

Clear or metal? There are different options to consider.

There are two main types of teeth retainer your dentist might recommend: a fixed retainer (also known as a bonded or permanent retainer) or one that can be removed such as an Essix or Hawley retainer. There are also special retainer braces which can be used for teeth straightening.

In this article we will guide you through all these options and explain how much retainers cost, both on the NHS and privately.

We’ll also show you how to clean your retaining device to make it last as long as possible.

What’s 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 to maintain the changes made to your teeth once braces have been removed.

Retaining devices can be made from clear plastic, metal wire, or a combination of the two. The different types of retainer function in slightly different ways, but they have the same purpose.

How do retainers work and why do you have to wear one after braces?

The best way to keep your teeth straight after braces

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, and 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 fixed 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 of retainer: fixed or removable, plastic or metal, but they all have the same goal: to stop your teeth becoming crooked again.

Can you use a retainer for teeth straightening?

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 of the best treatment for you.

Spring aligner retainers can help with simple movements of the teeth. They look similar to a normal Hawley device, but they have extra parts that move one or more teeth slightly or help to prevent the teeth from overcrowding or twisting.

Our guide to teeth straightening has more details of the options for getting straighter teeth with and without braces.

If you want to straighten your teeth without fixed metal braces, invisible braces could be a good solution. These systems use clear, removable aligners, which look the same as clear plastic retainers and are almost invisible when worn. Unlike retaining devices though, clear aligner braces are carefully designed to put pressure on certain teeth to move them into the desired position.

If you only need mild or moderate teeth straightening, you might be eligible for “mail-order” aligners from Straight My Teeth. These cost just £999 and can straighten teeth in around 9 months. You don't visit a dentist's office; instead everything is done from home and a dentist monitors your progress remotely. Read more about Straight My Teeth here or visit their website to take a free assessment and find out if you're eligible for this treatment.

What else are removable retainers used for?

There are other things, aside from maintaining straight teeth, that a dentist might recommend a dental retainer for. These include:

  • Stopping tongue thrusting
  • Helping a child to stop sucking their thumb
  • Preventing damage from bruxism (teeth grinding)

Types of retainers

As we’ve mentioned, there are a few different types of retaining devices available. We’ll give you some information about their plus points and downsides and show you what each retainer looks like, but you should listen to your dentist's advice about what’s best for your teeth.

Hawley Retainer

Hawley: plastic and metal

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 customise the colour of the plate or add a pattern.

This is one of the cheapest retainers 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 to some braces treatments that need a head piece. As mentioned earlier, spring aligners can be added to offer minor teeth straightening.

Essix Retainer

These clear plastic devices are hard to notice

If you want a clear retainer that is removable then an Essix type 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 discoloured over time, but you can prevent this with a proper cleaning routine – more on this later.

Vivera Retainer

This is the clear, plastic retainer from the manufacturers of Invisalign braces (sometimes called an Invisalign retainer). It is made from a 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 braces to be able to get a Vivera retainer.

Fixed Retainer

A completely different option is a fixed bonded retainer. Also called a lingual or permanent retainer, this type is only used on the front six teeth, often just on the lower jaw. A strong wire is glued behind the teeth, permanently retaining the shape you achieved with braces. It might need to be replaced every 3-10 years.

Fixed retainers are a little more expensive 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 attached to your teeth does make it difficult to clean and floss properly. Read more about the pros and cons of permanent retainers.

How much do retainers cost?

There are lots of factors that determine the price of a retainer. Which dentist you go to, where the surgery is, and what type you are recommended to use can all affect the cost. Here’s a rough guide to how much different retainers cost with a private dentist:

Type of retainer Material Permanent or removable? Price range Lasts for:
Fixed (bonded) Wire fixed behind teeth Permanent £100 - £400 3 - 10 years
Hawley (metal) Wire and plastic Removable £70 - £150 5 - 10 years
Essix (clear) Clear plastic Removable £50 - £135 6 months - 3 years
Vivera (Invisalign) Clear plastic Removable £300 - £420 (3 or 4 pairs) 1 - 5 years

Note that prices are for a single device, except for Vivera Invisalign retainers which come in a set of 3 or 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 price. There are other factors to consider as well; the cost of a removable retainer may be lower the cost of a permanent one, but how often will you have to replace them?

Can you get retainers on the NHS?

Under 18’s are entitled to free dental treatment on the NHS, and this applies to orthodontic treatment and retaining devices, as long as the work is deemed medically necessary. The only thing that isn’t covered is the cost to replace a retainer that’s lost or broken beyond repair; this is £70.10 per device so £140.20 for a complete set.

Generally speaking, the NHS 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

This guide from the British Orthodontic Society explains more about what's covered by the NHS.

Only private patients get fun options like this

Note that you won’t get to choose which type of appliance you get on the NHS; your dentist will decide which one is best for your needs. You probably won't get any fun customisation options, either.

Most adults are not eligible for braces and retainers on the NHS, except where there is a clear medical need for the treatment. In this case, a consultation or an appliance adjustment falls under the Band 1 charge of £22.70, while treatment with braces (including the first set of retainers) falls into Band 3, costing £269.30.

What does a replacement retainer cost?

Under-18s who get their treatment on the NHS must still pay to replace retainers that are lost or damaged beyond repair. The NHS has set replacement retainer costs, currently £70.10 per device. This is the only time you’ll have to pay for a retaining device if you are under 18 years old.

With a private dentist, often a new retainer costs the same as the original. There might be some saving if you don't need new dental impressions.

Damaged retainers can sometimes be mended. 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 should you wear retainers after braces?

You'll be wearing your device long term

Your teeth will slowly move throughout your life, especially if you had your braces before your wisdom teeth erupted. 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 a retaining device for the rest of your life.

If you have a removable retainer, you’ll probably be asked to wear it nearly all 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.

How to keep your retainer clean

Cleaning your retainer 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 odours. Clear retainers will also become discoloured if you don’t clean them properly.

Removable and permanent retainers need different types of care. Your dentist will show you the best way to clean your retainers, and we also have a full page on how to clean retainers with more detail and some natural products to use. For now, here's a quick overview:

Removable retainers

You can follow these simple steps for the best way to clean plastic retainers as well as metal ones:

Use a specialised cleaning product to keep bad smells and stains away
  • 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, using a soft bristle toothbrush to brush away plaque and bits of food.
  • Use a cotton bud to get into any deep grooves.
  • Some dentists will recommend you soak your device in a retainer cleaning product like Retainer Brite. Follow your dentist’s advice and the instructions on the product packaging.
  • To clean clear retainers that have turned yellow, gently scrub using baking soda, water and a soft toothbrush.
  • Never use whitening toothpaste on your Hawley or Essix retainer! It can be too rough and abrasive, so stick to soap and water.

The video below shows how this looks in practice for Shabrina, who wears clear retainers. She explains what she does for a daily clean morning and night, as well as for a deep clean several times a week. She says the deep clean is important for getting rid of any smells that inevitably build up:

How to clean fixed retainers

Use interdental brushes like these to clean under a fixed wire.

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.


There are several types of teeth retainers you can wear after braces, but they all have the same aim: to keep your teeth in position after they have been straightened. It’s also possible to get retainer braces which provide mild correction.

Whether you decide to get a fixed retainer or a removable Hawley or Essix retainer, the important thing is you follow your dentist’s instructions for using it properly. They will tell you how long to wear your retainer each day and how to clean it properly so it lasts as long as possible.

Remember, if you're looking for a way to straighten your teeth without wearing traditional braces, invisible braces are very effective and hard to notice. Check whether you're a suitable candidate by taking a two-minute assessment from Straight My Teeth right now. Their treatment costs just £999!

Teeth Retainer FAQs

Do retainers hurt?

Retaining devices can hurt sometimes, but usually just for a day or two after fitting. The 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.

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?

Choose a clear device if you'd prefer something less obvious

It is important to wear a plastic or wire retainer after braces, but which retainer 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 good and negative points about each. Weigh up your options, but remember that a removable retainer 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.
