My 8 month old baby doesn't have any tooth yet, is it normal? what shall i do?

Normal variation: Teeth can be present at birth or not erupt until 15 mo in otherwise normal children. It is not a sign of a dietary deficiency or other worrisome problem.Although average is 1st @ 4-6m and 1/m thereafter, many delay until older. Those that do often get several at the same time.

Teething: Although most children begin teething by 6 months, some are born with 1 or more teeth already erupted, some don't get 1st tooth until age 18 months. Usually if children are slow to teeth, their pedants or grandparents were also slow to teeth. Whether or not teething begins soon, make appt with Dento-Facial Growth & Development Specialist Dentist, a Pedodontist, on or about 1st b'day.
