DD is 2 yrs old and has just been diagnosed with severe childhood caries. Her 4 top front teeth need crowns and my dentist has already noticed decay on one of her molars. I understand that there are many factors that play into her tooth decay but want to know if you think I need to stop night nursing. We are already brushing a lot with fluoridated toothpaste and zylitol. I have cut out sweets, sugars, dried fruit, etc. In your opinion, do you think I need to night wean? Is it possible her teeth are predisposed to cavites and that she may have problems even after I night wean?
