Why cleaning your retainers matters

Retainers sit closely against your teeth, so any bacteria or plaque on them transfers directly into your mouth. Clean retainers help prevent:

• Bad breath
• Staining
• Bacteria build‑up
• Gum irritation
• Unpleasant taste

‍

Daily cleaning keeps your retainers clear, fresh and comfortable.

‍

How to clean Toothfairy retainers properly

‍

Step 2: Brush gently

Use a soft toothbrush and lukewarm water.Brush the inside and outside of the retainers using small circular motions.

‍

Step 3: Use mild, clear soap

A gentle, fragrance‑free soap helps remove bacteria without damaging the plastic.

‍

Step 4: Rinse thoroughly

Make sure no soap remains on the retainers before wearing them again.

‍

Step 5: Let them air dry

Place retainers on a clean surface and allow them to dry naturally.

This can permanently distort the shape.
