This is my first time to have a tooth filled here. It's not a big place. There are many people waiting in line. I suggest going early. It's full of partitions. I don't like this. Maybe it's because I will get off work soon in the afternoon. The cleaner began to clean the floor. It's too early. After all, there are still many dental patients in it. The clean dust is so dirty that the dentist always asks questions. Our patients are looking at their teeth. Can't we concentrate?
