Retainers are often prescribed after orthodontic treatment to help keep your new smile in place. Although it might be irritating having to wear yet another device, a retainer is an essential part of your treatment.
Read on to learn more about the purpose of retainers, why they’re crucial, and what to expect in this new phase of your orthodontic journey.
Teeth can shift back even after braces
Retainers keep teeth in place
There are removable and fixed retainers, removable is more common
Retainers can increase chances of tooth decay and inflammation
Keeping retainers clean is important
Retainers are orthodontic appliances that are usually used to retain the changes made by orthodontic treatment. In other words, retainers prevent tooth movement back to their original, crooked places after you get your braces removed [1].
Relapse happens as the fibrous tissues around the teeth pull them back into their original position.
The success of orthodontic treatment depends on teeth staying in the correct position, so using a retainer is at least as important as wearing braces. Unlike braces, however, you probably won’t have to wear them constantly. They also don’t interfere as much with activities or eating.
There are two types of orthodontic retainers: removable retainer and fixed retainer. Removable retainers are far more common than the fixed variety.
Removable retainers might be:
There are also several types of retainers that are fixed and cannot be removed [2]. Sometimes, they are also called bonded retainers as they are fixed to the teeth with adhesive. The most common type is the fixed lingual retainer, which runs across the tongue-side of the lower, front teeth. They are usually worn for longer and sometimes may be permanent retainers.
Many people are reluctant to wear an orthodontic retainer. In fact, as many as half the people prescribed orthodontic retainers will stop wearing them after a couple of years [3].
People who don’t wear their dental retainers risk a return to crooked teeth. Unfortunately, there’s no method of straightening teeth naturally and once that happens, the only solution is going back to braces.
Faced with wearing a retainer, it might make sense to wonder why it took so long to straighten your teeth if tooth movement is so easy. It’s important to remember that, while your braces have been at work for a year or two, your teeth have been growing for your whole life.
Teeth are held in place by ligaments and tissue, not just bone. It’s a bit like your teeth are attached to your jaw by rubber bands. After braces removal, the stretched ligaments want to pull teeth back to where they are. Retainers hold the teeth in place until the ligaments relax into the new position.
Most people wear their retainers for at least a certain amount of time after their orthodontic treatment has been finished—wearing it even once a week can be helpful. Additionally, you may only have to wear your retainer for a limited time.
While some people may have to wear retainers indefinitely, that’s more likely after crossbite correction or other more serious corrections.
If you don’t wear your retainer you risk having your teeth shift. A certain amount of shifting is inevitable and the lower incisors of most people, the lower teeth at the front of your mouth, will shift throughout their lives.
It’s not clear how risky it is to stop wearing your retainer. As much as 80% of people who don’t wear their retainer regularly may not see any significant change. On the other hand, 20% went through all the trouble of wearing braces, only to have all that undone.
About 20% of people who underwent orthodontic treatment saw their teeth shift back due to not wearing a retainer as aftercare
Whether you had traditional metal braces or clear aligners, you’ll be presented with a plan for using orthodontic retainers. You’ll need to wear them until your teeth settle into their new positions. Unfortunately, there’s no general rule for how long that will be since each case is different and will depend on a wide variety of factors.
In general, retainers are worn for one of two lengths of time. First, retainers are worn during the day and taken out to sleep, to eat, or for other reasons. The second is the opposite plan, worn overnight and removed during the day.
Removable retainers are usually not worn 24 hours a day. This is true for both Hawley retainers and clear plastic retainers.
There is no fixed length of time for the use of retainers. Removable retainers are usually worn for a shorter period, though not necessarily. Fixed retainers may be worn for longer periods and may be a permanent retainer. However, fixed retainers have a high degree of failure and may last only a few years.
There are many factors that can influence the length of time required, one of the most important being the severity of the correction.
Some patients that use clear aligners, such as Invisalign patients, are closely monitored by an orthodontist who will judge the patient’s needs. Retainers are required after Invisalign treatment. With some of the less expensive Invisalign alternatives, you don’t work as closely with a dentist. However, you will have to wear retainers after using invisible braces, like Byte.
Invisalign aligners and clear aligner treatment are usually used for less severe corrections, particularly cosmetic changes to the front teeth. As a result, you may end up wearing retainers for a shorter period. Other factors, like Byte’s Hyperbyte tool, may also influence the need for retainers. You can learn more about that in our Byte Aligner review.
Most likely, you’ll have to wear your retainers for 24 hours a day for at least the first two weeks. After that, you’ll be wearing retainers at night for at least a while. There is no set length of time for continuing to wear clear retainers. Although, Byte mentions that in order to maintain their guarantee, you must continue to order a new retainer every year
Remember, clear aligners are a type of orthodontic treatment and require the same type of maintenance as traditional braces. Almost certainly, it will be a clear plastic retainer rather than wire or Hawley retainers. Find out more in our nighttime clear aligners review.
It’s ironic but true that orthodontic treatment actually makes you more vulnerable to tooth decay and gum inflammation. As with braces, retainer wear provides bacteria with all sorts of opportunities to hide, while also providing spots for food debris to collect.
The result is greater plaque buildup, which can lead to cavities, gingivitis, and worse. The only way to prevent those issues is good oral hygiene and also keeping your retainer clean.
Whether you’re using plastic retainers or wire retainers, the first step to keeping it clean is to take it out before eating. This is particularly true when eating or drinking sugary foods.
A Hawley retainer may seem less vulnerable as they don’t fit as closely to the teeth. However, it’s important to remove them as well.
Otherwise, simply brushing your retainers with water and toothpaste is probably enough to keep them clean [4]. While all sorts of special cleaning agents are available, they don’t seem to be any more effective.
Keeping fixed retainers clean is just as critical, though it is often much more difficult. A fixed or permanent retainer is usually lingual retainers, plastic or multi-strand metal wires that are bonded to the palatal or lingual side of the teeth [5].
The process of fixing a wire-bonded retainer is complex and fiddly, so fixed retainers can be fragile. At the same time, it’s important to clean around the bonded retainer and between the teeth it is fixed to. While dentists recommend flossing for everyone, it’s particularly important for folks with a fixed retainer. As with braces, a floss threader can make cleaning a bonded retainer much easier.
Here are the answers to common questions.
There are many different types of retainers, each designed to meet different needs. However, they all have the general purpose of keeping teeth where they were moved, retaining the changes that were made. While they can make dental hygiene more difficult, retainers are an important part of orthodontic treatment and shouldn’t be neglected.
