To safely whiten dentures, start by using a mild approach to avoid damaging the material. Create a paste with baking soda and water, and gently brush the dentures with a soft-bristle toothbrush. Soaking dentures in a solution of equal parts white vinegar and water for 30 minutes can also help lift stains without harsh chemicals. Additionally, using a diluted hydrogen peroxide solution can brighten them; just be sure to rinse thoroughly afterward. Avoid using regular bleach or abrasive cleaners, as they can harm the dentures.
