Personally I don't have dental insurance; its the only thing not covered in my policy. :/
So every time I go to the dentist, I pay for it myself. It's not a big thing though; just routine checkup; cleaning and polishing as I see fit. So it doesn't cost me a lot; maybe around $50.
I brush my teeth twice a day; in the morning and before going to bed. I also use mouthwash after lunch.
And I visit my dentist every 2 months.
I also do not smoke so I don't have staining in my teeth.
