Re: tooth decay info
This article on KellyMom discusses tooth decay. The closest I can find is this quote: "...the antibodies in breastmilk counteract the bacteria in the mouth that cause decay". However, it's good to keep in mind this point: "...when a small amount of sugar was added to the breastmilk, the mixture was worse than a sugar solution when it came to causing tooth decay. This study emphasizes the importance of tooth brushing and good dental hygiene."
My thinking is that breastmilk itself will not cause existing cavities to be worse. However, those cavities are hard to clean, making it hard to get all the food particles and sugar and whatnot cleaned out. So if the decay is just a little discoloring, or a very small cavity, then night nursing (after thoroughly brushing those teeth!) will not be harmful. But if you're combating larger cavities, then nursing may become troublesome.
DS1 had nasty caries that required his 4 upper incisors be capped. I night nursed throughout the whole ordeal, and I don't think it made things worse. He had a larger cavity on one of his molars that we and his dentist kept an eye on for months before it was filled (waiting for him to be old enough to not require IV sedation). I night nursed during that whole time and the cavity never got worse; I did, however, make darn sure to brush that sucker really good every night and morning!
Good luck with those baby teeth, and hoping your little one's teeth aren't as soft as my DS1's!
