What does toothpaste do when I’m brushing? Why is it better than not using toothpaste?
In: Chemistry
Brushing alone gets debris off. With toothpaste, it gets the bacteria off. It binds to (and sometimes kills) the bacteria, so you spit it out. Fluoride strengthens enamel, too, by giving it protection against the acidity of bacteria, which erodes teeth and forms cavities.
