Throughout your life, you will have two sets of teeth: primary (baby) teeth and secondary (permanent) teeth. At age 6-8 months, the primary teeth appear; all 20 are in place by age 3.
The first permanent teeth, usually molars and incisors, will begin to emerge around age 6. The next teeth to erupt are the second permanent, or 12-year molars. Except for wisdom teeth, all permanent teeth are generally present between ages 12 and 14.
Last to erupt are the wisdom teeth. These third molars typically begin breaking through from age 17 and on. The total number of permanent teeth is 32, though few people have room for all 32 teeth. This is why wisdom teeth are usually removed.
Your front teeth are called incisors. The sharp “fang-like” teeth are canines. The next side teeth are referred to as pre-molars or bicuspids, and the back teeth are molars. Baby teeth are as vitally important as your permanent teeth. Baby teeth may be present in the mouth for up to 12 years. They function in the same way as permanent teeth and should be regarded as important as the ones you keep for life. So it is essential that both baby teeth and permanent teeth are brushed and flossed regularly and that periodic check-ups by a dentist are followed.
