Your dentures will act as your real teeth, but they can’t be cleaned the same way. Hard-bristled toothbrushes and regular toothpaste can leave small scratches on your dentures. This can tarnish their appearance and decrease their lifespan. Food particles and plaque can get trapped in the small crevices, leading to unpleasant odors. It’s best to use a soft-bristled toothbrush and mild hand soap or dishwashing liquid to clean them. You can also purchase OTC cleaning solutions designed for denture wearers.
