Often people ask us how long they need to wear their retainer after having orthodontic treatment. There are many factors that may influence how long someone needs to wear their retainer, but the best blanket recommendation we can make is to wear your retainers for as long as you want your teeth to stay straight.
The Purpose of Retainers
Regardless of whether you had traditional braces or Invisalign treatment, you will still need to wear a retainer in order to maintain the results achieved through orthodontic treatment. Without consistent wear for the rest of your life, you risk the chance of your teeth returning to their pre-orthodontic position.
A simple way of understanding why this happens is to think of your teeth as having a memory of their own. Typically, it takes about a year for teeth to become stable in a new position. During this time period, your teeth are especially likely to want to shift back to their old position because bone has not yet fully formed around their new position to keep them stable. A retainer helps train your teeth to stay in their new ideal position while this process takes place.
Timeline of Retainers
For the first 3-6 months of being braces free, you should aim to wear your retainers 22 hours/day. When your orthodontist feels confident that you are achieving some stability, they will give you the go-ahead to transition to nighttime only wear. You should continue wearing your retainer every night until you have been in retainers for about a year. After a year has passed, you should be okay to wear your retainer every other night for the rest of your life.
If you ever feel that your retainer feels tight, you should resume wearing it every night until the retainer slightly loosens into a more comfortable position. As you age your teeth will begin to naturally shift forward. This process doesn’t happen instantly, but over time it can have a noticeable effect on your smile. Wearing your retainers regularly will help prevent this from happening.
Types of Retainers
There are three main types of retainers that your orthodontist may have you wear. It’s important to understand that none of these retainers are made to last a lifetime. With regular wear, they will slowly become less effective. So in order to wear retainers and preserve your straight smile for the rest of your life you will need to have them replaced periodically.
Bonded (Permanent) Retainers
Bonded retainers are made by forming a wire along the back of your teeth and securing it so that it holds your teeth in their desired position. Bonded retainers can be made for both the upper and lower teeth but may not be recommended for both depending on your bite. These retainers generally require more daily maintenance and need to be both flossed around and brushed around daily. Bonded retainers can last anywhere from 2-5 years depending on how well they are cared for.
