How do you get clean teeth?

Brush, floss.... Brush after every meal, floss twice a day, use mouthwash twice a day, and see your dentist every 6 months!
Brush and floss. You should brush and floss properly (for at least 2 minutes) after each meal and all snacks. Rinse your mouth out when this is not possible. Eat healthy and visit your dentist regularly for check-ups and cleanings.
