OK, thank you, PPs.

Crowns...wow. Glad you got that second opinion!

My DD had/has it on all four back baby molars. She has had cavities in all four and had them filled. Not really a big deal, she handled the fillings just fine with novacaine. FWIW, the first dentist we went to tried to convince us to crown all four teeth under sedation as a preventative measure. We got a second opinion and I AM SO GLAD I DIDN'T take such a drastic measure. Also, none of her six-year-old molars (permanent teeth) were affected.

I'm 41 and have this on both of my lower adult canine teeth and I've never had a cavity. The dentist has always watched it closely and I'm pretty diligent when brushing this area. I don't know if it was on my baby teeth or not, but on the up side, they're her baby teeth so they won't be around forever.

The other day I noticed that my 2yo's lower corner teeth both had a small pit on the surface (where there used to small white spots). I started to freak out, thinking they were somehow cavities, despite using children's fluoridated toothpaste on her daily since her teeth came in (we live in an area w/out fluoridated water). I brought her to the dentist and they said that based on the symmetrical location of the pits on opposing teeth and the lack of any decay, it's basically a birth defect in the form of an enamel abnormality. Probably due to an illness or fever I had when pregnant.

Did anyone else's children have this, and if so, did it set them up for cavities? Did it affect their adult teeth as well? TIA.
