How to Clean Your Teeth

Brushing

Brushing should be done at least twice a day, and may be done after every meal. That being said, after eating or drinking anything acidic, it is important to wait at least an hour before brushing as to avoid damaging the teeth.

Wet your toothbrush slightly. Dry, your bristles may scratch and aggravate your gums.
Apply a pea-sized amount of toothpaste. The toothpaste should contain the relevant amount of fluoride, which differs for children and adults.
Point the bristles at a 45 degree angle to your teeth and gums, ensuring that they cover both your tooth and gum. Use a back and forth motion, cleaning 2-3 teeth at a time. After cleaning the front, make sure to brush the inner surfaces of the teeth as well. Don’t forget the back molars!
Brush gently along the gum line, once again remembering to reach the back molars.
Brush your tongue! This will get rid of bacteria, and help with your breath.
After brushing, which should take about two minutes, spit out your toothpaste, and rinse your mouth with water.

Flossing

Flossing doesn’t need to be done as frequently as brushing, though it is important to floss at least once a day. Right before bed is a great time to do so.

Take about 18 inches of floss, wrapping the floss around your fingers.
Grasp the floss, pulled tightly, between your thumbs and index fingers.
Gently insert the floss between each pair of teeth, using gentle back and forth motions to clean the teeth and gums. Make sure to go up above the gumline
Floss between each of your teeth, being careful not to neglect the back molars. If necessary, clean the floss between insertions.
