Cavities are hard to see in the early stages, but you might notice a small, white, chalky area on your tooth enamel. As the cavity gets worsen, you may see brown or black spots.

Tooth pain does not always indicate a cavity. While they are a common cause, other factors can cause pain, including tooth issues, such as tooth sensitivity to hot and cold, an abscessed tooth, or a cracked or chipped tooth. Other things, such as gum disease, a sinus infection, even teeth grinding or clenching, can cause pain. Regardless, it's essential to see a dentist if you experience tooth pain, even if you don't think it's a cavity. They can diagnose the cause and recommend appropriate treatment.
