Four years of working on my own businesses coupled with an 8 hour-a-day, full-time job took its toll on my dental health by last summer.  I have to wear a bite guard at night because I clench my teeth, and the stress had shown itself in an unseen crack that was becoming impossible to treat without a root canal. I've gone to my regular dentist, Dr. Hallman, since I was 10 and I just love him and his staff. I was going back and forth to him and the root canal guy because after the root canal, I was still feeling discomfort and I was told the whole point of a root canal is not to feel anything anymore.  It was ultimately over a year of back and forth until they redid everything and finally saw the crack.  A couple of months ago, Dr. Hallman was putting the finishing touches on the crown.
