Braces made new misalignments and gaps in my teeth about as much as it straightened them. Though his assistant or whoever always does braces. He replaced mercury fillings with this new white stuff which was nice, but he screwed up a couple times, continually on one tooth resulting in the necessity to drill out the nerve, took a long time and many tries for him to numb the right nerve, and eventually broke the tooth in half, and the temporary he had to bust out by shattering it with these big pliers, and the permanent is like a bubble, hardly resembles my actual teeth. Another tooth he attempted to fill he chipped and just left it, never repaired it. Other then that the fillings were pretty good. He also got me a great deal with my insurance.
