We know that teeth are very important for us。We use them to enjoy all kinds of delicious food。
But now，many children have a toothache because they don't protect their teeth well。So I want to give some advice about how to protect our teeth well。
First，we must brush our teeth twice a day。Second，we can‘t eat too much sugar。Third，we'd better go to the hospital to check the teeth on a regular basis。 Last but not least，we should change our toothbrush once two months。
Follow my advice，let's protect our teeth。
