Hi, I've had huge problems with my teeth since my daughter was born. They were really painfull but the dentist couldn't find any holes or reasons for it. Finally I went to see another dentist and he asked me if I was bulimic and I laughed at him and said no I've just had a baby and still eating for 2, lol. The dentist laughed and asked how bad my morning sickness was. I threw up all day everyday for 31 weeks and the dentist said that the acid from my stomach had eaten away the enamel from my teeth. I was horrifed and exclaimed that I had brushed my teeth religiously to get rid of the stomach acid in my mouth which I then found out had actually made it worse, lol. I felt like a complete idiot !! that I didn't know this stuff before. Anyway he put me on to a product called Tooth Mousse which comes in all sorts of flavours (I have Melon). It's about $30 and can be bought at the dentist and you use it similar to toothpaste and it helps to rebuid the enamel on your teeth. It's worked for me.
