Hlo dr.My baby is 1 year and 9 months old, and her 2 center teeth in the bottom haven't come in yet. She had 2 teeth at the time of birth, which fell out when she was 1 month old, but those teeth haven't grown back yet."

A. Those were prenatal teeth so don’t worry about it the new ones will come the milk teeth will come when the time is right the entire set of teeth can be seen between the age of three months to 3 years so you have left with enough time right now there is no problem nothing to be worried
