10 Fun Facts About Teeth You Probably Didn’t Know
Brooklyn is full of personality, and so are your teeth. In fact, we think teeth are pretty fantastic, which is why we’re so passionate about them. Whether you’re grabbing a slice on 5th Avenue or cheering on your kids at Prospect Park, your smile is one of the first things people notice about you. At Park Slope Dental Arts, we love helping patients of all ages understand not just how to care for their teeth, but also how incredible they really are. Here are ten fascinating facts about teeth. We’re pretty sure a few of these might surprise you!
Let’s Talk Teeth!
Your teeth do much more than chew. They help you speak clearly, shape your face, and show emotion. Each one has a unique structure and function that contributes to how your mouth works as a whole. From the microscopic strength of enamel to the deep roots anchoring each tooth, there’s a lot of science behind every smile.
At Park Slope Dental Arts, we use advanced technology like digital X-rays, iTero® digital scans, and CariVu™ cavity detection to study and protect these structures in detail. “Our technology allows us to identify potential issues as early as possible, which allows us to treat proactively,” says Dr. Edward Lee, co-owner of Park Slope Dental Arts. “However, it also helps us show patients just how amazing their teeth are, by helping them see what we see and allowing us to explain why we do things the way we do.”
Surprising Tooth Trivia
1. Teeth Can’t Heal Themselves
Unlike bones, teeth lack living cells that regenerate when damaged. Once enamel is gone, it’s gone for good. That’s why early detection of decay or cracks is critical. Using tools like CariVu transillumination, our dentists can spot tiny cavities before they spread, allowing us to repair them with conservative treatments that preserve as much natural structure as possible.
2. Your Smile Is Truly “One-of-a-Kind”
No two smiles are alike, not even among identical twins. The shape, spacing, and alignment of your teeth are influenced by genetics and habits, making your dental “fingerprint” truly unique to you. That’s why personalized treatment matters. Whether we’re creating a custom nightguard, a dental implant, or a clear aligner plan, we use digital impressions to capture every detail of your individual anatomy, so everything we do can be customized. You’re an original!
3. Enamel Is the Hardest Substance in Your Body
Enamel’s crystalline structure gives it remarkable durability, even harder than bone. It protects the softer dentin and pulp beneath from bacteria, acids, and temperature changes. However, it’s not invincible. Acidic foods, grinding, and improper brushing can wear enamel over time. Tools like Overjet AI help us monitor subtle enamel changes and identify early erosion before you experience pain or sensitivity.
To keep enamel strong, we recommend:
- Using fluoride toothpaste to remineralize surfaces
- Rinsing after acidic foods like citrus or wine
- Avoiding overly abrasive whitening products or brushing too hard
4. Ancient Toothpaste Was Made of… What?!
Here’s an extra fun tooth fact. Long before minty gels and sleek tubes, people brushed with some pretty strange concoctions. The ancient Egyptians mixed crushed eggshells, pumice, and ashes to polish their teeth. Greeks added vinegar and ground bones. Thankfully, modern dentistry has evolved. Today, we focus on safe, evidence-based care and gentle cleaning techniques like Guided Biofilm Therapy (GBT) with EMS Airflow®, which uses air, water, and fine powder to remove buildup without abrasion or discomfort.
5. Shark Teeth vs. Human Teeth
Sharks lose thousands of teeth in a lifetime, replacing them in rows that rotate forward like a giant, terrifying conveyor belt. Humans, on the other hand, get just two sets (baby and permanent teeth). Once an adult tooth is lost, it won’t regrow. That’s why we offer dental implants as a long-term solution to restore both function and bone health after tooth loss. Implants mimic natural roots and help maintain jaw strength, which is something even sharks can’t claim.
6. Teeth Start Developing Before You’re Born
Fun fact: tooth development begins around six weeks in the womb. Six weeks! The buds for baby teeth form under the gums before birth, while adult teeth start developing underneath them shortly after. This is one reason why prenatal nutrition and maternal health play a role in a child’s oral development. Once those baby teeth erupt, regular dental visits are key. Our board-certified pediatric dentists make those early experiences positive and educational, setting the stage for a lifetime of healthy habits.
7. Flossing May Help You Live Longer
It’s true! Flossing can do more than keep your gums healthy. Research shows that controlling gum inflammation supports your overall health, potentially reducing risks associated with systemic conditions. And as we all know, daily flossing is great for your gums!
At Park Slope Dental Arts, we reinforce the oral-systemic connection through advanced periodontal therapies. OralDNA® saliva testing identifies bacteria linked to gum disease, allowing us to personalize treatment with antimicrobial rinses, probiotics, or LANAP® laser therapy for optimal results.
8. Kids Have 20 Teeth, Adults Have 32
Children’s primary teeth start appearing around six months and usually fall out by age twelve, making room for 32 permanent teeth. This includes four wisdom teeth that often need removal. Monitoring this transition is essential. Our digital panoramic X-rays and growth tracking tools let us evaluate tooth development, alignment, and jaw growth in real time.
When orthodontic treatment is needed to make room or align those 32 teeth, our board-certified orthodontist, Dr. Richard Lee, uses Damon™ Braces, Spark™ Clear Aligners, and Dental Monitoring to track tooth movement remotely between visits.
9. Chewing Helps Your Brain
Score another one for eating! Chewing activates regions of the brain related to memory and alertness. On a related note, it also boosts saliva flow, which neutralizes acids and helps remineralize enamel. Proper chewing depends on stable, well-aligned teeth, which is why we emphasize occlusal balance in all restorative and orthodontic treatments. For patients with TMJ issues or bite instability, we use the Kois Deprogrammer to analyze jaw function and relieve strain, so you can chew more comfortably.
10. A Tooth Can Survive Outside Your Mouth (Briefly)
If a tooth gets knocked out, time is everything. It may be possible to save the tooth if it’s reimplanted within an hour. Handle it only by the crown, gently rinse off debris, and keep it moist in milk or saline, not water. Then get to a dentist right away. Our team provides emergency care and uses digital imaging and biocompatible bonding materials to stabilize the tooth, and we can restore it if reimplantation isn’t possible.
Teach Your Kids Fun Facts About Teeth
Kids love learning cool trivia about their teeth, which can help make dental care more fun. Use these tooth facts to start conversations about brushing, flossing, and regular checkups. In our Brooklyn dental office, our board-certified pediatric dentists incorporate hands-on demos and digital visuals to help kids understand how their teeth grow and change.
