How do you clean calculus off dentures?

To clean calculus off dentures, soak them in a solution of equal parts white vinegar and water for about 30 minutes to help dissolve the buildup. After soaking, gently scrub the dentures with a soft-bristle toothbrush or a denture brush to remove any remaining deposits. Rinse thoroughly with water before placing them back in your mouth. Regular cleaning and maintenance can help prevent calculus buildup in the future.
