Annual Dentist Check-Up

I usually don't mind going to the dentist once a year for a check-up. I think I haven't had cavities since I lost my milk teeth. So unlike other people I know I go to the dentist quite relaxed and without feeling queasy. But this time he found a cavity!! In order to fill it he anaesthetised half of my mouth by giving me several injections! This was actually the most painful part. The rest was alright since I couldn't feel anything for the next 4 hours. I had to be careful not to bite my tongue or my cheeks. So when it is time for my next annual dentist check-up I will probably not be that relaxed any more.
