my son is 6 year 11 months old bt uske teeth ab tak ni nikle is it normal

A. Dear parent, the first permanent tooth to erupt in the mouth is lower front teeth which occurs around 6-7 years. Many children whose milk teeth erupt late show delayed eruption of permanent teeth as well. However, individual variations are common. You can visit your nearest pediatric dentist for a regular check up. A dental check up is recommended every 6 months for children.
