Finishing braces or Invisalign is a milestone, but the teeth aren’t done moving. The fibers and bone around newly straightened teeth need time to settle, and teeth tend to drift back toward where they started, a process called relapse. A retainer stops that. Planning for retention is the last step of orthodontic treatment, and it decides whether your result lasts.
This page covers why retainers matter, the retainer we recommend, how long you will wear one, how to care for it, and what to do if it is lost or cracked.
Why Teeth Shift After Treatment
Moving teeth means remodeling the bone and stretching the ligaments around them. When braces or aligners come off, those tissues are still adapting, and the elastic fibers around the teeth pull them back toward their old positions. Growth and normal aging also cause gradual change over a lifetime, which is why many adults who had braces as teens notice crowding creep back in.
Wearing a retainer as directed is the simplest way to keep the result you invested in. Skip it for a few weeks early on and a retainer that fit perfectly may feel tight or stop fitting, and lost movement can mean going back into treatment.
Vivera Retainers at Leiker Orthodontics
At Leiker Orthodontics, we recommend Vivera retainers. Vivera retainers are clear, removable and custom-made from the same technology behind Invisalign aligners. As a Platinum Invisalign Provider, our practice works with this system every day.
- Durable: Vivera retainers are made from a proprietary thermoplastic designed to resist cracking and wear better than ordinary clear retainers.
- Precise fit: they are built from a digital model of your finished smile, so they fit your teeth closely.
- Discreet: the clear material is hard to notice when you smile or talk.
- Easy to maintain: you take them out to eat and clean them, then put them back in.
We capture that digital model with our iTero 3D intraoral scanner. A small handheld wand replaces impression putty, which many patients, especially those with a sensitive gag reflex, appreciate. Your retainer is part of your treatment plan, so ask at your consultation how it’s handled in your case.
How Long Do You Need to Wear a Retainer?
Retention has two stages:
| Stage | Typical wear | Why |
|---|---|---|
| Right after treatment | Most of the day and night, as directed | Bone and fibers around the teeth are still settling and relapse risk is highest |
| Long-term | Usually nights only, as directed | Teeth keep changing slowly for life, and nightly wear holds the result |
Your exact schedule depends on how your teeth moved and how your bite finished, and Dr. Leiker will set it at your debond appointment. The honest long-term answer is that if you want your teeth to stay straight, plan on wearing a retainer at night indefinitely.
Why Bite Stability Starts Before the Retainer
A retainer holds what treatment created, so a stable bite at the end of treatment makes retention easier. Dr. Brad Leiker trained at the Roth/Williams Center for Functional Occlusion in a two-year program focused on functional occlusion, TMJ health and comprehensive orthodontic care. Our practice treats with that functional jaw-positioning philosophy. The goal is a bite that fits together in harmony with the jaw joints, not just straight front teeth, so your result has less reason to drift once treatment ends.
Caring for Your Retainer
- Clean it daily with a soft toothbrush and mild, non-abrasive soap or a retainer cleaner. Toothpaste can scratch clear plastic.
- Keep it away from heat. Hot water, dishwashers and a hot car in a Texas summer can warp the plastic.
- Use the case. Most lost retainers are wrapped in a napkin at a restaurant or in the school cafeteria. If it isn’t in your mouth, it belongs in its case.
- Keep it away from pets. Dogs love chewing retainers.
- Brush before you put it in, especially at night, so you aren’t sealing food against your teeth.
- Bring it to your checkups so we can confirm it still fits.
Lost, Cracked or Tight Retainer?
Call us as soon as you can. The longer you go without a retainer, the more your teeth can shift, and a delay of even a few weeks can mean a new retainer no longer fits the way it should. If your retainer suddenly feels tight, keep wearing it and let us know. Tightness usually means teeth have started to move and need the retainer back in regularly.
Retainers, Nightguards and Grinding
A retainer keeps teeth in place, while a nightguard protects them from clenching and grinding. If you grind your teeth at night, mention it at your visit. Leiker Orthodontics also makes custom nightguards, and Dr. Leiker can recommend the right appliance for your situation.

Retainer Questions
Do I have to wear my retainer forever?
To keep teeth straight long-term, most people should keep wearing a retainer at night indefinitely. Full-time wear is usually needed only for the first stage after treatment.
What happens if I stop wearing my retainer?
Teeth tend to drift back toward their original positions. Small shifts can sometimes be corrected by getting back into a retainer quickly. Larger relapse may need more treatment.
What is a Vivera retainer?
Vivera is a clear, removable, custom-made retainer from the makers of Invisalign. It’s the retainer Leiker Orthodontics recommends.
How should I clean a clear retainer?
Brush it gently each day with a soft toothbrush and mild, non-abrasive soap or a retainer cleaner. Rinse it in cool water, never hot, and store it in its case.
