Always clean your dentures over a basin of water or a damp towel to avoid breakage if you drop them. Hold them gently between your thumb and fingers, and brush them using a denture brush and denture cleaner or soap - all readily available at any drugstore. Use only lukewarm water and avoid gritty pastes or powders. You should clean your dentures after every meal.
