My daughter has 4 teeth now she iw 11 months and I don't know if I should brush or not.and what oral hygiene to maintain for her.

A. Teeth can errupt at any time from birth  But most of the baby have their 1st teeth between 5-15 months of age  Teeth eruptions is a natural process  No need to do anything for that  Don't give any medication for that unless fever and exessive crying.  Just do gum massage with ur little finger thrice a day   Give teether if possible, Clean teether every time before use.  It will help  r
