Hey

For the past few days I've had a toothache that would come and go. Its in one of my top molars, and it seems like in the morning its fine, but as the day goes on the ache starts to appear when I am chewing or clenching my teeth, and gets worse by the end of the day. What can this be? I know I clench and grind my teeth as a bad habit sometimes throughout the day, can this be a factor?
