生活百科：護(hù)牙系列之四——怎樣正確刷牙

Steps 步驟

STEP 1
Apply toothpaste
擠適量牙膏

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
選好角度

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

STEP 3
Move in circles
轉(zhuǎn)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
清潔牙齒每一面

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
刷門(mén)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
刷舌頭頂端

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!
