Tooth decay

Tooth decay, also called dental caries or cavities, occurs when bacteria in your mouth produce acids that attack tooth enamel and the softer dentin underneath. These harmful bacteria feed on sugars and starches from food and drinks, and their acidic byproducts gradually erode the tooth's structure, creating holes that can become painful and lead to infection if left untreated. Regular brushing, flossing, and limiting sugary foods help prevent this process by removing bacteria and reducing the fuel they need to thrive.
