Yes. Retainers are essential after braces.
Why retainers are necessary
Teeth naturally move back: After braces, the bone and gums need time to stabilize. Without a retainer, teeth will relapse toward their original positions.
Memory of the teeth: Teeth have a biological “memory,” especially in the first 6–12 months after braces removal.
Bite stability: Retainers help maintain proper bite alignment, not just straight teeth.
What happens if retainers are not worn
Teeth shift and crowd again.
Gaps may reopen.
The results of months or years of orthodontic treatment can be partially or fully lost.
How long are retainers needed
First 6–12 months: Usually full-time wear (except eating).
After that: Night-time wear long term.
Many orthodontists recommend lifelong night wear to keep teeth straight.
Common misconception
“Once braces are off, treatment is done.”
In reality, retainers are the maintenance phase of orthodontic treatment.
