Retainers are the final — and permanent — phase of any orthodontic treatment. Relapse begins quickly once active treatment stops, which is why retention never truly ends. Orthodontists in Underhill typically fit them the same day braces come off.
The Retainer Wear Schedule
Guidance has shifted in recent years: removable retainers are now recommended indefinitely — full-time for the first 3–6 months, then nights only, then several nights a week for life. The old 'stop after two years' advice caused many relapses.
Fixed bonded retainers stay in place permanently unless they break, needing no daily decision — which makes them the most reliable long-term method.
Should your retainer feel tight after time away from it, that's early drift; see your orthodontist rather than forcing it back on. Acting quickly avoids a bigger, costlier correction later.

Retainer Replacement and Emergency Care in Underhill
Essix retainers need replacing every one to three years on average — heat from dishwashers, hot drinks or a hot car warps the plastic. Clean them with a soft brush and cold water, never abrasive toothpaste, and use cleaning tablets occasionally.
If you lose or break a retainer, contact an orthodontist in Underhill promptly — most can make a replacement Essix within a few days from a scan. In the meantime, wear your old one if it still fits: even a damaged retainer beats none.
After Your Braces Come Off in Underhill
When braces come off or aligner treatment completes in Underhill, protecting the result begins. The de-bond appointment, retainer fitting, whitening timing and retention habits all decide whether your result lasts. This guide covers everything that happens after active treatment ends.
Ongoing Check-ups After Treatment
Regular 6-monthly dental check-ups don't stop mattering once treatment ends — your dentist will still check a fixed retainer wire is intact, the gum around it is healthy, a removable retainer still fits, and there's no early sign of teeth moving. Get in touch with your orthodontist promptly if a removable retainer stops fitting easily, a fixed wire looks like it's shifted, or you notice any change in tooth position.
