68 most interesting dental facts that will blow your mind

As it turns out, most people only know a fraction of things about the dental world. Reading through these facts might help you realize this too. It may aid your oral health to learn a couple things. Plus, your new party trick could be shooting out teeth-related trivia.

Hyperdontia is a condition that causes too many teeth to grow in your mouth

Yes, this is the disease of your nightmares. Often causing many orthodontic problems, hyperdontia makes you grow extra teeth. In extreme cases, teeth can cover the whole roof of the mouth.

Regular dental cleanings can prevent heart attacks

Diabetes, high blood pressure, and heart disease can all be linked to poor oral hygiene. While regular dental cleanings are recommended by the ADA at least once a year, many Americans neglect to do this. So get your teeth cleaned before you need to visit a cardiologist!

Tooth buds appear before a child is born

The substance which eventually makes up your teeth forms in the sixth week of fetal development. The hard tissues appear around 3 to 4 months into the pregnancy. So even though a baby has no teeth, primary and secondary dentition is all queued up and ready to go when the right time comes!

75% of Americans store their toothbrush too close to the toilet

Toilet water can disperse as far as 6’ into the air when you flush. Meanwhile, as many as 3 out of every 4 Americans store their toothbrush closer to the loo. What’s more, 52% don’t close the lid when flushing. This means that your toothbrush is likely to have fecal matter on the bristles! It could cause the spread of infectious diseases.

Teeth can be implanted to help restore eyesight

A part of a canine or premolar tooth can be implanted upon the eye to help those with sight defects regain vision. The procedure was first conducted in the 1960s in Rome, but the method has been perfected since then.

Dental fillings are believed to be 13,000 years old

Yes, that’s right. Tooth decay has been around as long as we have. And it seems like ancient humans did not simply sit around with this problem on their hands. Scientists have recently found evidence of dental fillings being done in the hunter‐gatherer period in Italy. It was a little more brutal, though, as the earliest anesthetic wasn’t in use before 1846.

The Crocodile Bird cleans the crocodile’s teeth

Its real name is the Egyptian Plover and it eats leftover food particles and parasites. This is an example of symbiosis, a relation between two animals that is beneficial to both. You could say that the crocodile bird is a sort of a private dentist in the reptile kingdom.

Tooth enamel is the hardest biological material

Even though it is very thin, enamel is the hardest natural substance. In fact, it is harder than gold, silver, and steel! It is a lot more brittle, though, so it still wouldn’t make very good construction material.

A snail’s mouth is no larger than the head of a pin, but it can have over 25,000 teeth

Snails are the toothiest animals on earth. Their dentition may not be exactly the same as ours, but it serves the same purpose: it helps them eat. The umbrella slug goes through about 750,000 throughout its lifetime.

Spinach can minimize tooth sensitivity

When spinach breaks down in your mouth it merges with saliva to make calcium oxalate crystals. Those are commonly used in dental treatments, allegedly minimizing sensitivity by targeting dentin.
