Interesting facts about dentistry and teeth

Do you have an affinity for dental facts? Look no further. We’ve found a few interesting truth bombs about your teeth and gums. 

A bright and clean smile can be very welcoming, and it’s the first thing strangers look for when you meet. But besides the aesthetics, your teeth, mouth and anything related is very important for your overall health. 

Particularly your teeth. Without those chompers, you wouldn’t be able to chew your food – and would probably be in loads of gastric distress. 

Here are some interesting teeth and dentistry facts to chew on. 

Keep your teeth clean.

Brushing just once or twice a day isn’t enough. The sugar in the stuff we eat can get stuck in the nooks and crannies and start to erode the surface of the teeth. You should be rinsing your mouth after meals. 

  • If you drink more than two glasses of soda a day, Children’s Dental Village says that you would have more tooth decay, fillings and tooth loss than other people. Try freshwater instead. Soda has more than ten teaspoons of sugar.
  • When you don’t floss, you kiss up to 40% of your tooth surfaces. Brushing and flossing your teeth must be done twice a day. 

Fun dental facts

Did you know that the hardest substance in your body is tooth enamel? But, that doesn’t mean you should be opening bottle caps or biting through thick plastics. You stand a chance of cutting into your very fragile gums or cracking a tooth!

Teeth suddenly crack because of:

  • Teeth grinding (the pressure weakens the teeth, and eventually they crack).
  • Large fillings that weaken the tooth’s integrity.
  • Chewing or biting hard foods: ice, nuts, or candy.
  • Blows to the mouth can also crack the teeth, Healthline says. These include blows from a car accident, sporting injury, fall, or even a fistfight!

Surprisingly enough, an abrupt temperature change in the mouth can crack your teeth! — for instance, from eating something extremely hot and then trying to cool your mouth with ice water, you can crack your teeth! 


Teeth are dentin that is covered with enamel. The dentin expands and contracts slower than the enamel. So, when you expose a tooth to a sudden temperature change, the junction between the dentin and enamel is stressed, resulting in crack formation.
