Dr. Littman used to be my general dentist. We asked Dr. Littman for a referral for an orthodontist for my teeth, and he said that he could do it himself. BIG MISTAKE! My work was never finished, he added procedures along the way and billed for them, and the "permanent" wire he put in the back of my teeth became dislodged very quickly from two of the teeth it was glued to. Also, according to every dentist I've seen since Dr. Littman, he put on way too much cement when glueing the wire to my teeth.
