Cavities, also known as dental caries, are small holes that can form in your teeth. Consider your teeth sturdy, protecting castles from microscopic critters known as germs. These bacteria enjoy eating sugary and sticky things such as candies and cookies; when they do, they release acids that can damage your teeth. These acids chip away at the solid walls of your teeth, causing microscopic gaps similar to cracks in a castle wall.
If we don't properly care for our teeth by regularly brushing them with toothpaste and a toothbrush, these openings might grow larger and evolve into cavities. Cavities are uncomfortable, so be a tooth-protecting knight or princess and clean your teeth regularly to keep your castle solid and healthy!
