After braces or aligners, the bone and fibres around each tooth need time to settle. During the months of remodelling, retainers hold the teeth precisely where treatment left them. Any orthodontic practice in Sidcup can fit, replace or repair them if you need it.

How Long Do You Need to Wear Retainers?
Modern practice is lifelong retention for removable retainers — daily wear at first, easing to nights only long-term. Stopping entirely, even years later, remains the commonest cause of teeth drifting back.
Fixed bonded retainers stay in place permanently unless they break, needing no daily decision — which makes them the most reliable long-term method.
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.
Types of Retainer Available in Sidcup
Fixed (bonded) retainers are thin wires bonded behind the front teeth — usually the lower six, sometimes the upper too. They're permanent, invisible from the front, and need no daily effort, though they require careful cleaning with floss threaders to keep the gum healthy.
Essix retainers are clear thermoplastic trays much like aligners, removed for eating and cleaning. They're discreet and comfortable but can warp with heat and typically need replacing every 1–3 years.
Hawley retainers are the traditional acrylic-plate-and-wire design. They're more durable than Essix trays, adjustable if minor movement occurs, and can last many years — but they're more visible when worn.
Many orthodontists in Sidcup now provide both a fixed wire for continuous protection and a removable Essix tray for overnight use, combining the strengths of each.
Life After Braces in Sidcup
When braces come off or aligner treatment completes in Sidcup, protecting the result begins. The de-bond appointment, retainer fitting, whitening timing and retention habits all decide whether your result lasts. Below we walk through the de-bond, retainers, whitening timing and long-term check-ups.
The De-bond Appointment
At de-bonding, brackets are removed using an instrument that gently fractures the adhesive bond, leaving enamel undamaged when performed correctly. Adhesive residue is polished off using a rotating buff — taking 10-20 minutes. You may notice mild sensitivity in the days after as enamel previously under brackets is exposed; this is temporary.
