3 Fun Facts About Teeth

Wendy J. Woudstra

People today tend to know a lot about their oral health, but the humans of ages past relied entirely on conjecture for answers about their teeth. Here are some fun facts about teeth that our ancestors certainly did not know.

Cavities Are Not Caused by Tooth Worms

In medieval times, most people thought dental cavities were made by tiny tooth worms. These little worms were thought to bore holes in teeth and then hide, out of sight, beneath the surface. The wiggling they did inside the tooth was believed to cause the pain of toothaches.

Today, of course, science has told us the truth about cavities, namely that they are really tooth decay caused by enamel-eroding bacteria in the plaque that builds up around teeth. When we eat sugary or starchy foods, the bacteria feed on the remnants left on our teeth, while simultaneously creating an acid that eats away at enamel.

Thankfully, we also know a lot more about preventing and treating tooth decay today than our medieval ancestors did; with preventative dental care, good oral hygiene, and a tooth-friendly diet, we can keep our teeth healthy for a lifetime. You can learn more about maintaining good oral health in the Colgate Oral Care resources.

Everyone Has the Same Number of Teeth (Mostly)

The great philosopher Aristotle believed that men had more teeth than women. Even though he was married, he must never have counted, because men and women both develop 20 primary or baby teeth, and when their permanent teeth come in, both sexes receive 8 incisors, 4 canines, 8 premolars, and 10 secondary molars.

Things get complicated, however, when it comes to the third molars, often called wisdom teeth. While most people grow wisdom teeth between the ages of 17 and 21 years old, in about 35 percent of the population, wisdom teeth never develop. Some scientists believe that in the future that percentage will continue to grow until humans no longer grow wisdom teeth at all.

Your Primary and Permanent Teeth Start to Develop Before You're Even Born

You may not realize that although you don't have any teeth visible when you're born, the tooth buds of your 20 primary teeth, as well as the 32 permanent teeth you will one day develop, are already present in your jaw. The only exception is your wisdom teeth, which don't begin to develop at all until adolescence.

All these fun facts about teeth serve as reminders that you can never know too much about taking care of your teeth and gums. Daily preventative care and regular visits to the dentist will ensure that you have a healthy smile for years to come.
