Cavities are a common dental issue that refers to the presence of holes in teeth, caused by decay. Typically, the surrounding area of the cavity will appear dark brown or gray.

Bacteria in your mouth, found in plaque, are the main culprits of cavities. These bacteria interact with carbohydrates and sugars in your food, creating an acidic environment that dissolves the protective enamel on the outer layer of your tooth.

Once the enamel is compromised, the softer dentin layer is exposed, leading to the formation of a cavity. If left untreated, the decay process will quickly progress and spread deeper into the tooth. It’s essential to maintain good oral hygiene, such as brushing and flossing regularly and avoiding sugary foods, to prevent cavities and other dental problems.
