Before You Start

Before cleaning, rinse the guard under cool running water to remove loose saliva and debris. Do not use hot water, which can warp acrylic. Remove the guard only when your hands are dry to prevent slipping. Ensure your workspace is clean, and dry the guard thoroughly after cleaning to prevent bacterial growth.

Caution: Do not use household bleach or abrasive cleaners on acrylic night guards. If the guard has cracks or warping, stop using it and consult a dental professional.

Time estimate: 5–10 minutes for routine cleaning; up to 15 minutes for a deeper clean with cleaning tablets.

Step-By-Step: How To Clean An Acrylic Night Guard

Rinse the guard under cool, running water to remove saliva and loose debris.
Gently brush the exterior and interior surfaces with a soft bristle brush for acrylic, using a non-abrasive toothpaste or a cleaner specified for dental appliances.
Apply a small amount of dental guard cleaning solution for acrylic night guard or a recommended cleaner to the brush and continue brushing to lift stains and biofilm.
Rinse thoroughly to remove all cleaner residues; residual chemicals can irritate the mouth if left on the surface.
For a deeper clean, drop a acrylic night guard cleaning tablets into a cup of cool water and soak the guard for the time indicated on the product packaging.
Rinse again after soaking and inspect for any remaining deposits. If needed, repeat the brushing and rinsing cycle.
Pat dry with a clean, lint-free cloth and place the guard on a dry surface or tray to air-dry completely before storing.
Store in a ventilated case or open tray to allow airflow. Avoid sealing wet guards, which can promote bacterial growth.
If you notice persistent odors or discoloration, consider alternating between the cleaning tablet soak and the brushing routine on a weekly schedule.
Perform routine cleanings daily or after each use, following the same steps to maintain hygiene and material integrity.
Schedule periodic check-ins with a dentist to ensure the fit remains optimal and the material integrity is intact.
Keep cleaning materials out of reach of children and pets to prevent accidental ingestion or misuse.
