Hi, I’m Dolphin. I’m very happy because a young dentist is brushing my teeth. September 20th is Love Your Teeth Day. I think our teeth need care. Teeth are our good friends. Remember to brush our teeth at least twice every day. If we clean and protect(保护) them well, they will be very helpful to us. Our smile will be more beautiful if we have white and firm teeth. How do we brush teeth? Here are some tips:

★Brush our teeth after meals and keep them clean. Brush three minutes every time.

★Brush our teeth in a right way. Brush back and forth on each tooth, and don’t forget to brush the inside of each tooth.

★Put the head of our toothbrush(牙刷) upward and keep it dry. And then germs(细菌) can’t grow on it.

★Go to the hospital and visit the dentist in time.
