- Kids in prehistoric times likely did not suffer with tooth decay. The American Dental Association says this is because sugar was not a part of their diet.
- Tooth enamel is the strongest substance in the human body; because it's so durable, healthy tooth enamel protects teeth from cavity-causing oral bacteria.
- Teeth contain stem cells. In fact, according to SingularityHUB, some researchers are using dental stem cells to regrow human teeth. If successful, this technology would mean we can biologically replace lost adult teeth for the first time in history.
- Unlike bones or other parts of the body, teeth are incapable of self-repair. This is why receiving fillings and other dental work is necessary to protect teeth from further damage.
- Tooth decay is actually classified as an infectious disease because it is caused by a particular strain of bacteria passed between multiple people.
Historical Trivia on Oral Hygiene
Even ancient populations understood the importance of oral hygiene. And while their methods and practices were rudimentary compared to those of today, many ancient cultures would go as far as to chew on tree bark or wooden sticks with frayed ends to clean their teeth. The History Channel explains how ancient Egyptians even brushed their teeth using a powdery substance made from pulverized eggshells and oxen hooves. Using these ingredients in powder form, and mixing with water, was slightly abrasive and may have been an effective means of removing remnants left by food.
