Interesting Tooth Facts

Here are some fascinating facts about human teeth that highlight just how unique and important they are:

1. Teeth Are As Unique As Fingerprints

Just like fingerprints, everyone has a unique set of teeth. Even identical twins don’t have identical dental patterns, which is why dental records can be used for identification.

2. Teeth Don’t Heal Themselves

Unlike bones, teeth can’t regenerate or heal once damaged. This is why cavities need fillings and why good dental hygiene is so crucial.

3. Tooth Enamel Is the Hardest Substance in the Body

Enamel, the outer layer of your teeth, is harder than bone and the hardest substance in your entire body. Despite this, enamel can still be damaged by acids, grinding, and poor oral hygiene.

4. Humans Have Two Sets of Teeth

Humans are “diphyodonts,” which means we have two sets of teeth: primary (baby) teeth and permanent (adult) teeth. Most people lose their last baby tooth by age 12 or 13.

5. Plaque Contains Millions of Bacteria

Dental plaque is a biofilm of bacteria that grows on teeth and gums. In just one milligram of plaque, there are about 100 million bacteria! Regular brushing and flossing keep this bacterial buildup under control.

6. Teeth Start Forming Before Birth

Although they don’t emerge until about 6 months after birth, a baby’s primary teeth start forming during the second trimester of pregnancy.

7. We Spend 38.5 Days Brushing in a Lifetime

On average, if you brush for the recommended two minutes twice a day, you’ll spend about 38.5 days of your life brushing your teeth!

8. Saliva Protects Teeth

Saliva helps protect teeth by washing away food particles, neutralizing acids, and providing essential minerals like calcium and phosphate that help keep enamel strong.

9. Ancient Cavemen Had Fewer Cavities

Early humans had much fewer cavities because they had diets rich in natural, unprocessed foods. Modern diets high in sugar contribute to the formation of plaque and cavities.

10. The Tooth Fairy’s Inflation Rate

The Tooth Fairy’s rate per tooth has increased over the years! In the U.S., the average payout for a lost tooth is now over $4, compared to just $1 or less a few decades ago.

11. Some People Are Born Without Wisdom Teeth

Not everyone develops wisdom teeth (third molars). Some people don’t have them at all, likely due to evolutionary changes in jaw size and diet over thousands of years.

12. Dental Implants Are Nearly as Strong as Natural Teeth

Dental implants, which are used to replace missing teeth, are incredibly durable. They can last for decades and function almost like natural teeth.

13. Ancient Civilizations Invented the First Toothpaste and Toothbrushes

The Egyptians created the earliest form of toothpaste around 5000 BC, using ingredients like crushed eggshells and ashes. Ancient toothbrushes included “chew sticks,” which were twigs with frayed ends.

14. Your Mouth Produces a Swimming Pool’s Worth of Saliva

Throughout a lifetime, the average person produces between 20,000 and 25,000 liters of saliva – enough to fill two large swimming pools. This saliva plays a crucial role in maintaining oral health.

15. Brushing Harder Doesn’t Clean Better

Contrary to what some think, brushing harder doesn’t make your teeth cleaner. In fact, brushing too hard can wear down enamel and cause gum recession. It’s best to use a soft-bristled toothbrush and a gentle, circular motion.

Our teeth are incredible tools, and understanding their unique properties helps us appreciate the importance of taking good care of them!
