Not bad. Sometimes our teeth are formed with cavities already inside of them and it doesn't take much for the for bacteria to enter those cavities and to cause them to Decay and grow. sometimes a small little cavity can go in pretty deep so the sooner you can get it looked at and possibly treated the better.
Go to a dentist for an inexpensive exam and X-rays to make sure and get definitive answers.Source(s): HATE going to the dentist? Watch THIS: https://www.youtube.com/watch?v=s3vTwwqKyMw
