I don't have dental insurance, but I still go every 6 months now. I went a LONG time without going at all. Then DW finally made me go, and I had gum disease.
It used to hurt so bad going to the dentist, but now that I've been treated, it's not bad at all. I get a deep cleaning twice a year (down from 4x per year) and I almost fall asleep in the chair every time now. Doesn't hurt at all. My hygienist is super impressed with how my teeth and gums have healed. I still hate getting fillings, but that's pretty rare now.
It is important to take care of your teeth, your oral health affects much of the rest of your body. And as far as discussing it on an RV forum, I'm often curious how full-timers deal with things like this. For me it's easy, my dentist is right down the street, and I know him personally. For full-timers, I would think even that simple stuff would become much more complicated.
