生活百科：护牙系列之四——怎样正确刷牙

Steps 步骤

STEP 1
Apply toothpaste
挤适量牙膏

Apply toothpaste to your brush. You only need a pea-sized dab of paste to do the job.

Adults should always use toothpaste with fluoride to fight tooth decay.

STEP 2
Angle brush
选好角度

Hold the toothbrush against your gums with the bristles at a 45-degree angle.

STEP 3
Move in circles
转圈刷

Move the brush in small circles using short gentle motions, making sure that you get under the gum line as much as possible. But don't brush too roughly—it may cause your gums to bleed.

STEP 4
Brush all surfaces
清洁牙齿每一面

Make sure you brush the top, front and back surfaces of each tooth. Don't forget your back molars. You should brush your teeth for 2 to 3 minutes.

STEP 5
Behind front teeth
刷门牙后面

To brush behind your front teeth, use the front tip of your brush and angle the bristles at a 60-degree angle. Brush gently up and down.

STEP 6
Brush top of tongue

Before rinsing your toothbrush, gently brush the top of your tongue to help get rid of bacteria and freshen your breath.

It's recommended that you replace your toothbrush every 2 weeks to 3 months—or whenever you've been sick—to keep harmful bacteria from building up.

STEP 7
Rinse mouth
漱口

Rinse your mouth out with mouthwash or water and smile, baby!
