Baby teeth and adult teeth begin growing when a baby is still in the womb. Baby teeth begin at 6-8 weeks of development and the adult teeth begin around week 20. When a tooth begins to grow under the gums, it is called a tooth bud (good vocabulary word). Humans have 4 types of teeth: incisors, canines, premolars, and molars. By the age of 3 years, most babies will have all their baby teeth. They will begin to lose their baby teeth around the age of 6, with the adult teeth replacing the baby teeth. They will continue to get new teeth until their wisdom teeth (which are molars) come in. Wisdom teeth typically come in around the age of 15-20 years old.
Ask your parents if they know how old you were when your first tooth came in and when you lost your first tooth.
Dental history (for the older students and those who are interested)
Write a short essay on dental history. Talk about how dental care and the materials use in dental care have changed over time. Here are a couple of sources to help you get started:
The Dental Center has an intermediate-level of dental history on their website with links to other dental history websites.
The American Dental Association also has a page of dental history that is much more in-depth and covers from ancient times to 20th century innovations and technology.
