i havent been to the dentist in like 5 years because i had no reason. my teeth dont hurt and i brush themand use mouth wash.
i thought that it was a good thing but my friend said that ist was bad because you have to get them cleaned every 6 months.
can you feel if you have cavities
No, you generally can't feel cavities, you're teeth will only hurt when a cavity has gotten so bad that you need a root canal. That's one of the big reasons for the check-up every 6 months, because cavities can be caught and treated while they're small, before you need such a painful, and expensive, procedure.
