#asktheexperts my baby is 11 months old n on his tongue we see light blue black residue, tried cleaning with cloth n baby tonge cleaner but he never cooperates. i m worried what could be the reason for this and is it harmful.

A. It Is blue maybe Your child may have eaten something which has turned the town or maybe I mean I’m not sure but it can be one possibility but as of now you should get a check with a paediatric dentist to be more sure and clear about it
