Retainers are the final — and permanent — phase of any orthodontic treatment. Teeth are under constant biological pressure to move, and retainers are the only reliable counter. Practices across Saint Lythans usually supply both a fixed wire and a removable tray for belt-and-braces protection.
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.
Because a fixed retainer removes the compliance question entirely, it's the surest safeguard against long-term drift.
A retainer that no longer seats is a warning sign — get it checked promptly. Catching movement early usually means a fresh retainer, not a full course of retreatment.
Looking After Retainers in Saint Lythans
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.
Treat a lost or broken retainer as time-sensitive. Any orthodontic practice in Saint Lythans can help, and catching a problem early is always far cheaper than dealing with relapse later.
