Throughout your life, you will have two sets of teeth: primary (baby) teeth and secondary (permanent) teeth. The primary teeth appear around ages 6-8 months, and all 20 are in place by age 3.
Your front teeth are called incisors. The sharp “fang-like” teeth are canines. In the primary teeth, the side and back teeth are molars. As your child grows and the permanent teeth erupt (come in), these baby molars are replaced by premolars, also known as bicuspids. The permanent back teeth are molars, which appear around ages 6, 12 and 18. Between the ages of 12 and 14, all of the primary teeth will be replaced by permanent teeth and all the molars, with the exception of wisdom teeth, will be erupted. The total number of permanent teeth is 32, though few people have room for all 32 teeth, which is why wisdom teeth are usually removed.
Permanent or adult teeth are the ones you keep for life.
