Retainer

A retainer is the final and often underestimated phase of any orthodontic treatment. Once fixed braces are removed or aligner therapy ends, the teeth are straight, but the surrounding tissue and jawbone need time to stabilise. Without securing them, the teeth would almost always shift again – the retainer locks the result in place.

There are two basic types. The fixed retainer is a thin wire bonded to the inner surface of the front or canine teeth, remaining permanently in the mouth. The removable retainer is a clear tray or an acrylic plate with a wire, usually worn at night. The two are often combined. Your orthodontist or dentist takes an impression or scan and makes the retainer to fit you individually.

A retainer is essentially needed after every active tooth correction – in adults just as much as in adolescents. Experts assume teeth have a lifelong tendency to drift, which is why long-term or even permanent wear is now often recommended.

Pay attention to regular check-ups: a loosened bonded wire or an ill-fitting tray can quietly allow teeth to move back. Good oral hygiene around the wire, careful cleaning of the tray and consistent wear are essential. Costs depend on the design, material and follow-up care – clarify the approach and any ongoing costs with your practice in advance.
