I floss pretty much every day now. Last time I went to the dentist he said I was in the top 5% of people if I did, which made me feel all proud!
Before I started flossing, every time I went to the dentist, I got five minutes of the high pitched tooth angle grinder thing, whereas if I do floss, the appointment takes no time. A small amount of time with the floss each day is quite satisfying, whereas 5 minutes of the angle-grinder is quite uncomfortable, even if it is just twice a year.
If you have trouble doing it, check out youtube for ‘how to floss your teeth’ videos, it is fiddly but once you have the hang of it you can do it pretty quick. Also, I find branded floss is better than non-branded cheap ones, cheap ones tend to fall apart in your mouth.
