25 Quirky Facts About Teeth to Share With Patients

Think you know your dental trivia? Let’s put your knowledge to the test with a quick game—true or false! Ready to dive in? Here are three quick questions:

First, how long does it take for sharks to regrow a tooth—42 days, 6 minutes, or 24 hours? Next, what percentage of Americans floss daily—55%, 69%, or just 30%? And finally, does frowning take less effort than smiling—true or false?

Locked in your guesses? Scroll down to find out how you did!

1. Unique Dental Imprints

You already know that a person’s smile is uniquely theirs—just like their dental imprint. But did you know this uniqueness can be pivotal in investigations? In criminal cases, forensic dentists rely on dental imprints to identify individuals and even solve cases.

2. Hardest Substance

Tooth enamel is the hardest substance in the human body, even stronger than bones. Patients must treat their enamel with care—because once enamel is eroded or worn away, it cannot grow back.

Understanding facts about teeth, such as enamel’s strength, helps professionals highlight the need to protect enamel from damage caused by acidic foods, sugary drinks, and habits like chewing ice.

3. Born with Teeth

Approximately one in every 2,000 babies is born with natal teeth, which are present at birth. Imagine the surprise (and the challenge) for new parents facing an early teether! While rare, these teeth sometimes need removal to prevent complications, as reported by pediatric dentists.

4. Not Everyone Gets Wisdom Teeth

About 25 percent of people never develop wisdom teeth. Consider yourself lucky if you’re one of them. I wasn’t so fortunate—I had all four removed when I was 25 and looked like a purple chipmunk for weeks!

5. Tooth Decay Prevalence

When I was a child, sugar-free sweets weren’t a thing. As you know all too well, tooth decay is the most common chronic disease in children. But many parents don’t know this.

Consider “cavity-free” stickers and sugar-free sweets as rewards for kids. Seeing them proudly show off their stickers is always a reminder of how impactful early prevention can be.

I can’t imagine squeezing in even one extra tooth; my tiny mouth barely has room for the ones I have!

9. Snail Teeth

Some species of snails have over 25,000 teeth, arranged in rows on their tongues. Can you imagine needing a dentist for that many teeth? What a slimy challenge! These teeth, called radula, are made of a material stronger than steel, according to a 2015 study.

Bizarre dental facts, like snails having thousands of teeth, can lighten the mood during a procedure. I find that children and even adults have a chuckle when they hear this.

10. Tooth Fairy Traditions

I love how each culture adds its own twist to celebrating childhood milestones. In Spain and Latin America, a mouse named “El Ratón Pérez” collects children’s lost teeth instead of the Tooth Fairy. Magical facts about teeth, like “El Ratón Pérez,” can leave an impression that stays with a child long into adulthood.

11. Teeth Reveal Age

Forensic scientists can estimate a person’s age by examining the wear and development of their teeth. In fact, a 2018 study in forensic science International showed dental analysis could estimate age with 90% accuracy.

Unique facts about teeth in forensic science, such as wear revealing age, fascinate patients.

12. Teeth and Gender

Certain dental features can help determine gender in forensic studies, though it’s not always definitive. It’s amazing how even subtle differences in molars and enamel can tell us so much.

14. Teeth and Diet

The wear patterns on teeth can indicate the type of diet an individual had, such as vegetarian or meat-based. If teeth could talk (and if it wasn’t for my dentist), mine would definitely reveal my love for caffeine!

15. Teeth and Stress

Enamel hypoplasia, lines on teeth, can indicate periods of stress or malnutrition during tooth development. Even our teeth carry the marks of life’s challenges—what a testament to resilience. Researchers link these lines to historical famines and childhood illnesses.

From diet to stress, many factors shape the fascinating facts about teeth professionals encounter daily.

16. Teeth and Health

Facts about teeth, like oral health’s impact on heart disease, can, essentially, save lives when communicated to patients.

As we know, oral health is linked to overall health; gum disease has been associated with heart disease and diabetes. According to research, treating gum disease can lower heart disease risk by 15%. I often share this fact with people who have poor oral health.

17. Saliva Production

The average person produces enough saliva in their lifetime to fill two swimming pools.

Sharing facts about teeth, like saliva’s protective role, can make dental education more interesting, especially with tweens.

18. Dentures in Space

Astronauts use special adhesives to keep their dentures in place in zero gravity.

One can’t help but imagine if they’d have to chase after their teeth if they didn’t have adhesives!

19. Taste Buds

The average person has about 10,000 taste buds, which are replaced every two weeks. Imagine we were born without taste buds or every food tasted the same. Smokers often lose taste sensitivity over time, highlighting the importance of a healthy mouth.

20. Smile Stats

Smiling activates 12 muscles in your face, and it takes fewer muscles to smile than frown. In fact, it’s estimated that smiling uses as few as 10 muscles, while frowning can engage over 40 muscles.

21. Tartar Buildup

When plaque isn’t removed, it hardens into tartar, which only dental professionals can remove. Sharing this with patients helps them understand the importance of regular cleanings to prevent tartar-related issues.

22. Flossing Myth

Only about 30% of Americans floss daily, even though it’s crucial. You can advise your patients to floss at least once a day.

23. Bruxism

Teeth grinding, or bruxism, can lead to tooth wear, fractures, and jaw pain. Understanding facts about teeth, such as teeth grinding, makes patients aware of the treatment options available.

24. Sharks Regrow Teeth

Sharks can regrow a lost tooth in as little as 24 hours. While it’s unlikely humans will ever match that speed, research into regenerative dentistry is making strides toward helping us restore lost teeth in innovative ways. These forward-thinking facts about teeth show how nature inspires advancements in oral healthcare.

25. Tongue’s Strength

The tongue is one of the strongest muscles in the body and plays a crucial role in speaking and swallowing. Fun fact: your tongue never truly gets tired, no matter how much you talk!

This is one of the facts about teeth that most patients won’t know and are always surprised when they hear it.

The Bottom Line

Nervous patients need distractions, and a lighthearted comment can make all the difference. These moments create connection. Suddenly, the dental chair feels a little less intimidating. Patients might leave saying, “My dentist told me the coolest thing about wisdom teeth today!” That’s free word-of-mouth marketing right there. The next time they’re due for an appointment? They’ll think of you—not because of the reminder text—but because they want to come back.

Facts About Teeth FAQs

1. How do dental professionals identify age or gender through teeth?

Dental professionals use wear patterns, enamel thickness, and the development of teeth to estimate age. Gender can sometimes be inferred from differences in tooth size and structure, though it’s not definitive. These fascinating facts about teeth are used in forensic science to uncover key details about individuals.

2. Can stress leave visible marks on a person’s teeth?

Yes, stress can cause enamel hypoplasia—visible lines or grooves on teeth that indicate developmental disruptions. These facts about teeth remind us that oral health can reflect periods of stress or malnutrition, often dating back to childhood.

3. What’s the significance of saliva in preventing oral diseases?

Saliva neutralizes acids, washes away food particles, and delivers essential minerals to enamel, acting as the mouth’s natural defense system. These critical facts about teeth highlight why reduced saliva production can lead to decay and gum disease.

4. Why can’t tooth enamel regenerate like other tissues in the body?

Tooth enamel doesn’t contain living cells, so it lacks the ability to repair itself. These facts about teeth emphasize the importance of preventative care, as once enamel is lost, it’s gone for good.
