May possibility na mahirapan syang mag-breastfeed. Pati ikaw, mommy. Mahihirapan kang mag-breastfeed kasi masasaktan ka sa tooth nya. If worried ka talaga mommy, dalhin mo na sya sa dentist nya. Pero, I think tutubuan pa rin naman sya ng normal permanent teeth nya once na matanggal itong natal teeth nya.
I know a few people who have babies born with 2 teeth already. They just leave it as it is. I haven't heard na nagka problem naman sila with the baby. But if you are not comfortable, you may go to a pedia dentist and see what's best to be done.
