Help! Canker sore turned into a deep, painful hole!

[nervousreality]

I had a canker sore for about 2 weeks in the beginning of October, and it kept coming back, but around the beginning of November, it began developing into what looked like a cut/hole. I’ve tried benzocaine and rinsing with hydrogen peroxide, but nothing has helped. The hole seems to be getting worse. It is painful to eat or even speak. I can’t tell if this is a sign of something bad, or if it’s just a cut that won’t heal! Please help!

Have your dentist prescribe Kenalog in Orabase (Dental Paste) 0.1%. The medicine may not be covered by insurance if you're in the US. Also have you dentist round and smooth some of the teeth cusps to minimize further trauma.
