You've probably got the kind of teeth that don't need cleaning much.
The last time I saw a dentist was when I was about 27. He said 'If you're going to have problems with your teeth, you'd have had them by now'. I'm 40 soon, rarely clean my teeth and don't have a problem. Money for old rope if you ask me (ymmv).......
