     I'm sure I'm not the only person (my age 15) who hates going to the dentist. Channel 4's late-night

documentary (纪录片) Open wide last Tuesday was excellent for people like me. However, none of my

school friends watched it because they didn't know it was on. Why can't television companies let us know

about such important programmes in advance?

     This pragrammes was important because it showed how methods for helping people with toothache

have developed over the centuries. If you think visiting the dentist today is an uncomfortable experience,

just be grateful you didn't live 200 years ago! Then, the programmes told us, the only cure for toothache

was removing the tooth. There weren't any dentists, so the person who cut your hair also pulled out your

bad teeth, and there was nothing to stop you feeling the pain.

     The programme has also completely changed my attitude to looking after my teeth. My parents were

always saying to me things like, 'Don't eat too many sweets.' And, 'Brush your teeth after meals.' But I

never paid much attention. Now I've seen what damage sugar can do, especially if I don't use a toothbrush

regularly. I'm going to change my habits. Many people would benefit from a repeat of this programme.
