Primary (baby) teeth

Upper and lower sets of primary (baby) and secondary (permanent) teeth, showing cuspids, bicuspids, incisors, molars, and wisdom teeth

An infant's first teeth are called baby teeth or primary teeth. They usually start to come in (erupt) between 6 months and 12 months of age. A total of 20 primary teeth erupt by about 3 years of age. Children begin to lose their primary teeth between the ages of 6 and 11 years. They are replaced by secondary, or permanent, teeth.
