My first reason why you should brush your teeth is so you don’t get “BAD BREATH”! After you gorge a lot of breakfast your breath can get a bit smelly, and you don't want that now do you. So after breakfast before you go to school brush your teeth and you won't have bad breath many more.
Another reason you should brush your teeth is so your teeth won't rot. If you brush your teeth you can abolish these rotten teeth and get nice teeth once again. Having bad breath is bad, but having rotten teeth is really bad so you should brush your teeth.
My last reason why you should brush your teeth is so you don't have to go and get them fixed. Do you want to spend a lot of money on getting your teeth fixed? Well you should brush your teeth so you don't have to get them whitten because they are rotting.
If you brush your teeth you can have a lovely gigantic smile. So I hope you brush your teeth everyday It's good to have nice teeth.
