Understanding Cavities and Prevention

The video discusses the issue of cavities, primarily caused by the bacterium Streptococcus mutans, which converts sugars into acid, leading to tooth decay. Despite regular dental hygiene, cavities can still occur. Scientists are exploring solutions like introducing beneficial bacteria in toothpaste and developing mouthwashes that target S. mutans. These methods show promise but require further research. The video also promotes Brilliant's problem-solving courses, which enhance logic and math skills.

What is a common misconception about the main cause of cavities?
