10 Fun Dental Facts You Probably Didn’t Know!

At Metro City Dentistry, we’re passionate about oral health—but that doesn’t mean it has to be boring! In fact, the world of teeth is filled with surprising, strange, and downright fun facts that will make you look at your smile a little differently. Whether you’re a parent trying to engage your child in brushing or just someone curious about dental trivia, we’ve got something that will make you say, “I didn’t know that!”

Here are 10 fun dental facts you probably didn’t know:

  1. Tooth Enamel Is the Hardest Substance in the Human Body

Move over bones—your teeth are the real powerhouses. Tooth enamel, the outer layer of your teeth, is the hardest substance in the human body. It’s even harder than your femur! But while it’s incredibly strong, it can still wear down or decay without proper care, which is why regular brushing and dental checkups are so important.

  1. Humans Have Two Sets of Teeth—Just Like Sharks (Sort Of)

Most people know we have baby teeth and adult teeth. But did you know that sharks also grow multiple sets of teeth during their lives—sometimes thousands? While we don’t replace our teeth as often as sharks do, we do start life with 20 baby teeth and eventually grow 32 permanent ones.

  1. Your Teeth Are as Unique as Your Fingerprints

No two people have the same set of teeth—not even identical twins! This makes dental records a powerful tool for forensic science. So yes, your smile really is one of a kind.

  1. The First Toothbrushes Were Made from Twigs

Before plastic toothbrushes and electric brushes came along, people used “chew sticks” made from twigs. These early tools were frayed at one end and chewed to help clean teeth. While not as effective as modern tools, they were an important first step in dental hygiene.

  1. There Are More Bacteria in Your Mouth Than People on Earth

Your mouth is home to over 6 billion bacteria, compared to about 8 billion people on the planet. Don’t worry—not all bacteria are bad! Many of them play essential roles in digestion and maintaining a healthy balance in your mouth. But some do cause plaque and cavities, so good oral hygiene keeps the bad ones in check.

  1. Flossing Can Extend Your Life Expectancy

Believe it or not, flossing does more than just prevent cavities and gum disease—it may also reduce your risk for heart disease. Studies show a connection between gum inflammation and systemic health issues, like cardiovascular problems. Daily flossing keeps your gums healthy and might even help you live longer!

  1. People Used to Believe Tooth Worms Caused Cavities

In ancient times, people thought toothaches were caused by tiny worms burrowing into the teeth. This myth was widely believed in cultures across the globe until the 1700s when modern dental science started to emerge. Thankfully, we now know bacteria and sugars—not worms—are the real culprits behind cavities.

  1. Some Snails Have Thousands of Teeth

If you think your dental checkups are complex, consider the garden snail—it can have over 14,000 teeth! Some species even have up to 20,000. These tiny teeth are arranged in rows on their tongue-like organ called a radula.

  1. Smiling Can Actually Boost Your Mood

Smiling does more than make you look friendly. It can actually trigger the release of mood-boosting chemicals like dopamine and serotonin. Even if you don’t feel happy, smiling can trick your brain into thinking you are. So go ahead—flash those pearly whites!

  1. George Washington’s Dentures Weren’t Made of Wood

This is one of the most persistent dental myths. George Washington did wear dentures, but they were not wooden. Instead, they were made of materials like ivory, metal, and even human or animal teeth. Let’s just say modern dental prosthetics have come a long way!
