答案和解析

It’s very important for us to have healthy teeth. It shows whether a person is healthy or not. Our school did a survey about the students’ dental health recently. According to the survey, about 49.09% of the students have got cavities.
Here are some causes. Many teenagers often forget to brush their teeth after eating snacks. Some like to drink soda drinks which can hurt teeth easily.
To improve dental health, we should eat fewer snacks, drink fewer soda drinks and brush teeth regularly so that we can keep our teeth clean and healthy.
Let’s pay more attention to dental health and try to avoid dental problems.
