A black eye is an injury that looks worse than it really is. A black eye, or shiner, can be caused by any damage near the eye or eyebrow. Even a small bump or knock can cause a spectacular black eye.

A dentist is someone who looks after other people's teeth. They clean your teeth properly, and fix up holes in people's teeth. They can also make your teeth look better by straightening or whitening them. Sometimes going to see the dentist can be painful or scarey, so if you don't want a dentist trip to be bad, you should look after your teeth and brush them every day.
