Tooth Decay or cavities are one of the most common dental issues that occur in patients. Tooth decay occurs when bacteria form a film, called plaque, on the surface of teeth. The bacteria produce acids from the sugars in food. The acids eat away at and permanently damage the enamel, or outer layer, of the tooth. The acids then start working on the softer dentin layer beneath the enamel.
This breakdown of the tooth can lead to cavities or holes in your teeth. It can also cause toothaches, including pain when you eat and drink hot, cold, or sweet things.
