Q. I broke my front tooth completely in half when I was about 8 yrs. old (I’m 39 now). A root canal was performed on the tooth, and bonding was done to repair the break. The tooth has a grey look to it now, and I went to the dentist today to check into having the bonding redone. The dentist told me that he would never do bonding on the tooth to change the cosmetic appearance, because of the fact that I had the root canal. He said the bonding would still look grey. He suggested a crown, but I’ve read that it’s very difficult to do a color match with a crown when only doing one front tooth. What would you suggest?,
