Children’s teeth begin developing in the womb. Your babies’ first teeth may begin to erupt as early as 4 months, and by and large, all 20 primary teeth have erupted by 3 yrs. of age, although pace and order of eruption varies.
Permanent teeth generally begin to appear around your child’s 6th birthday, and continue until their 21st birthday with the eruption of their wisdom teeth. This is why regular wellness visits are crucial for the health of your child’s permanent teeth.
