Question: I think I may have a cavity.  What does a cavity look like?  I notice a little black spot on my tooth the other day and have not been able to brush or floss it off.   It does not hurt but I worried that I have a cavity.

Reply: You can search images of dental cavities to get a feel for what one looks like.  However with that said. If you think you have a cavity it is best to go see a dentist to confirm what is really wrong with your tooth.

Also in case you are thinking it dose not hurt so what is the point in seeing a dentist, you should know that cavities do not always hurt and when they do you may have bigger issues then just a cavity. That is why you should see a dentist before having any dental pain issues. Go see your dental as soon as possible so that you can get your tooth taken care of.
