11 Things You Didnâ€™t Know About Teeth!
Your teeth may have been a small source of income as a child. You brush and floss them daily to stay healthy. They help you eat, talk and smile.
Here are a few things you probably didnâ€™t know about teeth.
1. Every personâ€™s teeth are different, just like our fingerprints.
2. By age 3, the average child has their full set of 20 primary teeth (often referred to as baby teeth). The average adult has 32 teeth, which includes wisdom teeth.
3. Baby teeth usually fall out in the same order they came in.
4. Up to 35% of people are born without wisdom teeth.
5. Humans are more primitive than you thought! We have four different types of teeth (incisors, canines, premolars, molars) in order to help us bite, tear and grind our food.
6. Straight teeth are not the beauty ideal in every culture. In Japan, some people will get crooked veneers to cover up straight teeth.
7. Your mouth produces more than 25,000 quarts of saliva in a lifetime.
8. Toothpaste as we know it today was first produced in 1873 and sold in a jar. Before that, people used charcoal or ground chalk mixtures.
9. Flossing daily is just as important as brushing your teeth to help get plaque out from between teeth. Your toothbrush misses 35% of your toothâ€™s surfaces!
10. If you floss once a day, you will use about 5 miles of floss over your lifetime.
11. At an auction in 2011, John Lennonâ€™s tooth sold for more than $31,000. In 1816, Sir Isaac Newtonâ€™s tooth sold for todayâ€™s equivalent of $35,700. Unfortunately, the Tooth Fairy brings an average of just $3 per tooth.
