May and Buddy went to the dentist yesterday. Good news - No Cavities!
May has discoloration on her front permanent teeth. When I asked the dentist about it, he said it happened as each tooth was forming when she was an infant, probably in the first year of life. Possible causes are too much amoxicillan or eating toothpaste resulting in too much flouride. I asked if drugs in utero could cause it, and he said it was possible, but didn't know of studies confirming that.
