After braces or aligners, the bone and fibres around each tooth need time to settle. Teeth are under constant biological pressure to move, and retainers are the only reliable counter. How diligently they're worn is what determines how long your Knockhall treatment result lasts.
Types of Retainer Available in Knockhall
Fixed (bonded) retainers sit permanently behind the front teeth as a discreet bonded wire, holding the result with zero patient effort. The trade-off is cleaning: floss threaders or interdental brushes are needed to keep the area healthy.
Essix retainers look just like a clear aligner and are the most common removable choice after aligner treatment. Discreet and easy, but treat them gently with heat and expect a replacement every couple of years.
Hawley retainers use an acrylic plate with a wire across the front teeth. Sturdier and repairable, they last far longer than clear trays at the cost of being more noticeable.
Many orthodontists in Knockhall now provide both a fixed wire for continuous protection and a removable Essix tray for overnight use, combining the strengths of each.
How Long Is Retention?
The current standard is to keep wearing removable retainers indefinitely, tapering from full-time to nights only. Abandoning them after a couple of years — once routine advice — is now recognised as a leading cause of relapse.
Fixed bonded retainers stay in place permanently unless they break, needing no daily decision — which makes them the most reliable long-term method.
If a removable retainer stops fitting after a gap in wear, don't force it — contact your orthodontist. A new retainer, or occasionally a short retreatment, is far cheaper than letting relapse set in.
