I was in a car accident a few years back. I broke my front tooth and the dentist bonded the corner where it broke. Well the past 6 years it breaks again at least twice a year. The last time I went to have it repaired was in the beginning of dec 2003. Well I am not sure that it is related but the last few days when I wake up my teeth are fine when my mouth is closed. However as the day goes on it seems like when I bite down my bottom fron teeth are hitting the back of my top front tooth. It is annoying and is starting to cause pain in my front tooth. I have no idea why this is happening and I thought if I ignored it, it would go away. No such luck, I made an appt. With the dentist and I feel like I am going to the dr for a paper cut. Does anyone have any suggestions why my teeth are doign this, is it normal? It hasn't happend to me ever before. Thanks!
