Monkeys eat raw plants and tough fruit, which naturally cleans their teeth. Humans eat soft food which sticks to the teeth and provides a place for bacteria to grow and produce the acid which rots our teeth. Brushing prevents this.

Reply:Humans will survive without brushing if they live in the jungle or in a zoo. But to survive in society, they%26#039;ll need to brush. Otherwise they won%26#039;t be able to mate and hunt for moolah against other humans who are perceived to be cleaner and more hygienic.
