A cavity is painful when it passes through the enamel and exposes the dentin to irritants in the mouth, such as debris, bacteria, and acids.
This is the clearest way to determine if a patient has a cavity. Acids in the mouth eat away at a tooth, creating these holes. A cavity will keep growing until it completely destroys a tooth or until it compromises the pulp chamber of a tooth, placing it at danger of infection.
When dental caries (tooth decay) progresses, it creates cavities in the teeth where bacteria thrive. These bacteria release foul-smelling gases that cause persistent bad breath.

Dentin contains tiny tubules that connect to the nerves of the tooth, and when it is exposed, it can result in sensitivity to hot, cold, sweet, or acidic foods and beverages. The sensation can be sharp and uncomfortable, making eating and drinking a painful experience.
