Like natural teeth, dentures can attract plaque, become stained, and collect food particles that can cause bad breath. They need to be cleaned daily to remove plaque and calculus. At home, dentures can be cleaned with over the counter cleaners and gentle bushing with a specialized denture brush. Ordinary toothbrushes and commercial toothpastes are too abrasive and can damage the surface of your dentures. When the plaque has hardened to calculus it will need to be removed at a denture clinic, so be sure to clean your dentures properly.
