After braces come off, the most critical phase of orthodontic treatment begins — the retainer phase. Skipping it can undo 1–2 years of work.
Why a retainer is needed
Teeth have a "memory effect" — they tend to return to the old position, especially in the first 6–12 months after braces. A retainer holds teeth in the new position and prevents relapse.
Retainer types
- Fixed (lingual wire) — a thin wire bonded to the back of the front teeth. Invisible, cannot be forgotten. Usually on 6 front teeth.
- Clear tray (Essix) — similar to an aligner. Worn overnight.
- Hawley retainer — acrylic with wire. Long-lasting but visible.
Often combined: fixed on front teeth + removable at night.
How long to wear?
- First 6 months: full-time (removable type) — off only for meals
- 6–12 months: nighttime only
- After 1 year: 3–4 nights per week, lifelong
Fixed retainers last 5–10 years without removal. They can stay longer if in good condition.
Retainer care
- Fixed: daily cleaning with superfloss or interdental brushes
- Removable: cool water, weekly effervescent tablet
- Do not use hot water — plastic warps
- Remove during sports
If lost or broken
Contact your orthodontist immediately — teeth start shifting within 48 hours. Delay leads to relapse.
