I'm nearing 30 and am now being told that I may have my first cavity. It's in a wisdom tooth.
It looks like a black spot to me and I saw it in my mouth for over a year. Dentist claims it's not a spot, but rather a hole (cavity)
Question is, is it worth filling on a wisdom tooth? Can cavities heal on their own? If it is a cavity that has been present over a year, shouldn't I feel pain?
