Is it possible for tooth decay or gum bleeding to have any affect on the breastmilk for a mom?

Possibly.: Bleeding gums have been linked to many other health issues including problems with pregnancy. I know of no study having been done regarding breast milk, but I do know that bleeding gums allow the oral bacteria to enter the circulation and be distributed throughout the body. The bacterial waste products are responsible for inflammation. Do these enter the milk?Get the gums treated to reduce worry.

Yes: Tooth decay and bleeding gums can be caused by bacteria in the mouth, which if it becomes an infection can affect the mother in many ways. Best to see your dentist and not risk possibly infecting your child.

Probably not: Probably not. However, active and untreated dental decay in the mother will increase the chance for your infant developing dental decay in the future. The cavity causing bacteria are transferred to the baby early on so get those cavities treated, improve the oral health of your mouth, and decrease the risk level for your baby.
