Hygienist dropped cleaning tool on my front crowns. #8 ended up breaking not long after appt. Dentist tried to fix #8 (see pics) but it does not match along gum line or color. He refuses to do #9 too but will do 8 again if I sign release form. The dentist that originally did my crowns at custom lab said it's too hard to match - do both. Wanted to get thoughts from others with experience. I want my front teeth to look the same, not kind of the same, as I am sure you can understand. Advice?
