Wondering what do cavities look like? Cavities typically appear as dark spots or holes on the surface of teeth, often accompanied by discoloration or visible decay. In more advanced stages, they may manifest as pits or craters. Regular dental check-ups can help detect cavities early on, preventing further damage and discomfort. Remember, maintaining good oral hygiene practices such as brushing, flossing, and regular dental visits can help keep cavities at bay.
