How many times should you brush your teeth a week?

You should brush your teeth two times a day and there are seven days on the week.. 2x7 is 14 so technically 14 times ;)

in a week*

Twice a day, everyday, two times seven is fourteen so 10-15

Once

3 times

14 cuz 2 times per day and 7 days in a week so you should brush your teeth 14 times per week.

3 times a day so 3x7 = 21

never

just kidding
