Finishing your last set of clear aligners feels like a huge win—and it is. But keeping that new smile in place takes a bit more effort. This next phase, known as retention, is just as important as the orthodontic treatment itself.
Without a retainer, your teeth may slowly shift back to where they started. All that progress? Gone. That’s why it’s important to treat your retainer like part of your orthodontic treatment plan, not an afterthought.
At Smilebliss, we make post-treatment care easy. Whether you’re a teen getting your first orthodontic retainer or an adult maintaining long-term results, we’re here to support you every step of the way.
Orthodontic retainers help lock your teeth into their new positions after aligner treatment. Even though your teeth look straight, they’re still settling into place. The tissues and bone around your teeth need time to adjust. A retainer gives them that time.
If you skip wearing your retainer, teeth can gradually shift back—especially during the first few months after treatment. This is called relapse. And the longer you go without a retainer, the more likely you’ll need to restart treatment.
Think of the retainer as a seatbelt for your beautiful smile. You wear it to keep everything safely in place.
There is one main type of orthodontic retainer we recommend after aligner treatment: a removable retainer.
These look like your clear aligner trays and are usually made of smooth, durable plastic. You can take them out to eat, drink, and brush your teeth. They’re custom-made devices and designed to maintain the shape of your final teeth alignment.
In the first few months after treatment, wearing your retainer full-time is typically recommended—usually 20–22 hours a day. This means removing it only when you eat or brush your teeth.
After a few months, you’ll likely switch to nighttime wear. For many people, this becomes a lifelong habit. That’s not a bad thing. Wearing your retainer while you sleep keeps your teeth stable and your smile looking great.
The general timeline looks like this:
Consistency is more important than duration. Skipping a few days now and then might not seem like a big deal, but it can add up over time.
Just like your clear aligners, orthodontic retainers need regular cleaning to stay clear, fresh, and bacteria-free.
Following these simple care habits helps reduce bacterial growth and prevents issues like staining, odor, and tooth decay.
Retainers don’t last forever. Depending on the material and how well you care for them, most need to be replaced every 6–24 months.
Watch for:
If any of these happen, it may be time for replacement aligners or a new retainer. Using a retainer that doesn’t fit properly can do more harm than good.
A healthy, straight smile isn’t just about wearing retainers—it also means keeping your teeth clean and your habits consistent.
Brushing and flossing every day helps prevent plaque and food particles from building up under or around your retainer. It’s important to rinse your clear aligners or orthodontic retainers daily and stay on top of your cleaning routine to avoid bacterial growth.
Be mindful of what you eat. Sticky candy, chewing gum, and certain hard foods can damage your retainer or cause it to fit poorly. Staying hydrated throughout the day also helps; drinking water not only keeps your mouth fresh but helps rinse away bacteria that could otherwise cause odor or buildup.
Stick to your orthodontic treatment plan closely, and don’t ignore small changes. If your retainer feels off or doesn’t fit like it used to, schedule a check-in. Good oral hygiene, combined with consistent care, helps prevent gum disease and keeps your new smile looking and feeling its best.
