I have one girl that will be 3 tomorrow and one that will be 2 in July. I am tandem nursing them. I recently took them to the dentist because I noticed a little tooth decay at the top of the milk teeth. The dentist said that they needed to be put under for surgery and tooth colored caps to be put on the 4 milk teeth for both of them. I never give juice, rarely give candy always brush teeth before bed and when they get up. The only thing that explains the decay is breast milk pooling in their mouth while going to sleep or nursing at night. Has anyone else experienced this or know of a way to prevent more cavities. They rarely fall asleep with out nursing. Should I wean them?
