That's actually something I've been looking into. Lactobaccilli levels are higher in breastfed children. That's one of the bacteria involved in tooth decay. Strep mutans is like the fire but lactobaccilli acts like fuel. It doesn't do much to start cavities on it's own but once it is introduced it really accellerates the process. Is that the sort of bacterial infection you are talking about?
I've had NO success in getting professional opinions on the topic. I have some studies and what not but when I tried to contact dentists with my questions I get no replies.
I'm glad you had a support system.
It is my middle child who suffered such severe decay that he lost almost all of his natural teeth. I still nursed him until he was almost 5 though

I breastfed my daughter (youngest) until she was almost 4 and night nursed her into well into her 2nd year without any tooth decay at all, so there is hope. There has *got* to be a way to still breastfeed our children naturally without having to put their teeth at risk, right?
I did night wean my son at about 3 and a half years old because I just didn't feel it was an acceptable risk anymore. His decay was so bad by then
I still think you would be a wonderful support to parents going through this. There are so many options, it's great to hear insight from those who followed a different path and especially if they found success!
