Although I don't have experience with this exactly, I just wanted to chime in with agreeing you should consider finding another pedi. Babies cut their first teeth anywhere from birth to a year, and some teeth for weeks on end & some seem to sail right through it without many signs or complaints. My daughter's first tooth was showing when she went in for her 6week check-up and I've read of babies born with a tooth already showing. (not common but it happens). My granddaughter teethed (drooling, chewing, mouth soreness, red spots on her cheeks etc) for weeks & weeks before she finally popped out with a tooth at 7-8 months. Babies are all different, I don't know why your doc would say it only happens at 6mos & it only takes a couple of days.
