I just learned a little about IN ternal bleaching for teeth stained by childhood medication. Internal, anyone know about that?
not external. apparently a holes are drilled in each natural tooth and a bleaching products goes inside the tooth to bleach the inside. this is for teeth stained from the use of a childhood medication that treated acne. who knew it would turn your teeth gray from the inside. topical products don't work. does anyone know about internal bleaching? what hapens to the hole, cost, results, pain?
