Why is chewing gum good for your teeth?

Question

On the back of my gum bag it said that chewing gum within 20 mintues after eating will help reduce cavities or something along the lines of that.

Answer 1

Chewing gum can help rub off and dislodge bits of foot that otherwise might linger and provide food for bacteria. That bacteria can damage your teeth. It’s the same thing for dogs chewing on bones and toys.

Edit: bits of “food” for most of us not “foot”
