What age do kids get all their teeth?

Most children typically have a complete set of primary (baby) teeth by around age 3, which includes 20 teeth. These teeth begin to erupt around 6 months of age and are usually all in place by the time they reach their third birthday. Permanent teeth start to emerge around age 6, and by the age of 12 to 14, most children will have lost their baby teeth and have a majority of their permanent teeth, including molars, in place. Full adult dentition, including wisdom teeth, generally develops in the late teens to early twenties.
