Ah, I figured that would be his answer.
Also remember there's more to brushing than simply brushing the teeth. Brushing your tongue for a minute, maybe more, will give you a cleaner mouth/breath, same with brushing your gums and the roof of your mouth; some people don't like using an electric brush on their tongue but you can turn it off and then brush it.
Plus flossing with also give you better breath and also give your dentist less things to complain about next time he sees you.
