1. It was discovered that ancient humans also cared for their teeth.
While ancient oral hygiene methods and practices seem rudimentary compared to those we use today, people back then had definitely figured out that there is a connection between oral hygiene and strong, healthy teeth.
Ancient people tried many different methods to keep their teeth clean. Some would go so far as to chew tree bark or wooden sticks with frayed ends to clean their teeth. Ancient Egyptians brushed their teeth using a powder made from pulverized eggshells and ox hooves mixed with water.
2. The toothbrush like we know, wasn't around until the 1700s.
A man in England named William Addis attached boar bristles to a bone handle to create the first mass-produced toothbrush. In the 1930s, brushes with nylon bristles and ergonomic handles were developed. These products seem primitive compared to modern toothbrushes, but they were highly innovative then!
3. Did you know that the Tooth Fairy's cost has gone up just like everything else?
Today, the Tooth Fairy needs a lot more silver than she did in 1900 when she left an average of twelve cents per tooth. In 1998, she left an average of one dollar. In 2013, the going rate for a tooth reached an average of $3.50. In 2018, it was not uncommon for kids to find a $5 bill under their pillows! How much do you get?
4. North Americans use over 4.5 million kilometres of dental floss yearly!
But we're still not flossing enough! Only 30% of North Americans report flossing once a day.
5. The average human produces more than 23,000 litres of saliva in their life.
That's enough drool to fill two swimming pools! Gross.
6. Teeth help us learn about the past.
Teeth are the hardest part of any mammal, which means they are the part most often fossilized. The size, number, shape, and organization of the teeth are different in every species of mammal, making them very useful in the classification of organisms (taxonomy). Without teeth, the fossil record would be quite a lot harder for us to understand.
7. Out of all the world, the US has more cavities than anywhere.
On the other hand, in some countries (like China), people eat such small amounts of sugar that entire cities are completely cavity-free.
8. If you hear the phrase 'Long in the tooth', it means 'old'.
This expression originated with horses. As horses age, their gums recede, making it seem like their teeth are growing. The longer the teeth look, the older the horse.
9. Snails have teeth — a ton of them!
Snails and slugs eat with a jaw and a flexible band of thousands of microscopic teeth called a radula. The radula scrapes up, or rasps, food particles and the jaw cuts off larger pieces of food, like a leaf, to be rasped by the radula.
10. According to Louisiana law, you'll be charged if you bite someone.
If you bite them with your natural teeth, it's assault, but if you bite them with dentures, it's aggravated assault. This is because simple assault is committed with your person, and aggravated assault is committed with a dangerous weapon (which dentures are, if you're using them for biting people).
