Caring for Your Retainer: Do's and Don'ts
Congratulations — if you've just finished active orthodontic treatment, you've reached an exciting milestone! But before you put braces or Invisalign fully in the rearview mirror, there's one more important step: retainers.
Think of your retainer as the guardian of all the progress you've made. Here's how to care for it properly so your smile stays exactly where it should.
Why Retainers Matter So Much
After braces come off or your last Invisalign tray is finished, your teeth are technically still "settling" into their new positions. The ligaments and bone around your teeth need time to stabilize — and without a retainer, teeth can begin shifting back toward their original positions, sometimes within just a few months.
Wearing your retainer as directed is one of the simplest things you can do to protect your investment in your smile.
Types of Retainers
Removable Retainers
These come in two common types:
Hawley retainers — a wire-and-acrylic design that's durable and adjustable
Clear plastic retainers (similar to Invisalign trays) — discreet and comfortable
Fixed (Permanent) Retainers
A thin wire bonded to the back of your front teeth, typically on the lower arch. These stay in place continuously and don't require remembering to wear anything.
Your orthodontist will recommend the type that's best for your specific case — sometimes a combination of both.
The Do's of Retainer Care
DO wear it exactly as directed
Whether that's full-time initially and then nightly, or just nightly from the start — consistency matters most in the first several months after treatment.
DO clean it daily
Rinse your retainer with water every time you remove it
Brush it gently with a toothbrush (a separate one from your regular toothbrush) and water — avoid toothpaste, which can be abrasive
Soak it periodically in a retainer-cleaning solution or a mixture of water and mild soap
DO keep it in its case when not worn
This is the single best way to avoid losing or damaging your retainer. If it's not in your mouth, it should be in its case — not in a napkin, pocket, or backpack.
DO bring it to dental cleanings
Your dentist or orthodontist can check that it still fits properly and address any issues early.
DO contact your orthodontist if it feels different
If your retainer suddenly feels tight, loose, or uncomfortable, don't ignore it — this can be an early sign that teeth are shifting.
The Don'ts of Retainer Care
DON'T use hot water
Hot water can warp plastic retainers, permanently changing their shape and fit.
DON'T eat or drink (other than water) while wearing a removable retainer
Food particles can get trapped, and sugary or acidic drinks can damage the material.
DON'T wrap it in a napkin
This is the #1 cause of lost retainers — napkins get thrown away, often with the retainer still inside.
DON'T let pets near it
Dogs especially seem to find retainers irresistible. Keep your case somewhere out of reach.
DON'T skip wear "just for a few days"
Even short breaks from wearing your retainer — especially early in the retention phase — can allow teeth to begin shifting. If you've taken a break and your retainer no longer fits comfortably, contact our office rather than forcing it.
What If You Lose Your Retainer?
It happens more often than you'd think. If your retainer is lost or damaged:
Don't wait — the longer you go without one, the more likely your teeth are to shift
Contact our office as soon as possible to discuss replacement options
In the meantime, if you have an old retainer that still fits, wearing it temporarily is better than nothing — but let us know so we can guide next steps
How Long Do You Need to Wear a Retainer?
This varies by patient, but many orthodontists recommend nightly wear indefinitely — or as long as you want to keep your smile in its current position. Think of it less as a temporary requirement and more as a small, ongoing habit (similar to wearing a seatbelt) that protects something you worked hard for.
