牙齿 (yá chǐ): 歯

Yesterday when I was eating fish, I accidentally got a fish bone stuck in my tooth, so I hurried to see the dentist this morning.

She brushes her teeth carefully every morning and evening, so her teeth are white and healthy, and she looks especially good when she smiles.

My little brother is very afraid of getting a filling; as soon as he hears the sound of the drill, he tightly closes his mouth and refuses to let the dentist examine his teeth.

Grandma is getting older, and several of her teeth are loose, so when she eats an apple she can only cut it into small pieces and chew slowly.

If you don't wear a protective mouthguard during sports, your teeth can easily get injured if you happen to bump your face.
