Retainers

People use retainers after orthodontic treatment because teeth naturally tend to return towards their earlier positions over time.

A retainer is made to fit snugly over or behind the teeth; its role is to hold the achieved position rather than move teeth through an active correction stage.

A dirty retainer can collect bacteria. Clean it daily with a soft-bristled toothbrush and water, and do not use hot water, alcohol, or bleach because they can damage the appliance.

Retention protects the orthodontic result by reducing the long-term tendency for teeth to shift. Relapse itself is a long-term problem, so tooth stability and retainer survival are important outcomes.

After teeth have been straightened, the retainer fits over or behind them to maintain that position. Wearing it as prescribed supports the longevity of the orthodontic result.

The retention phase begins after orthodontic treatment. Its purpose is not a short recovery period: it is to keep teeth stable against the natural tendency to move back over time.

Retention can involve different retainers and different wear protocols. Research compares tooth stability, retainer survival, adverse effects such as caries and periodontal disease, and patient satisfaction across these approaches.

Store the retainer in its protective case whenever it is out of the mouth. This helps keep it clean and lowers the chance that it will be damaged, broken, or lost.

Retainers are part of the phase that follows orthodontic treatment, when the aim is to keep straightened teeth from returning towards their original positions.
