I feel exactly the same way. When I had a dental plan, it seems I got too much dental care, and now that I have no plan, I can't get any. They won't even let you pay on installment here (B.C. Canada) you have to pay cash or put it on your credit card. I don't have one so I just do without.
I had a problem a while back that I dealt with by swishing my mouth with energized water, and it seems to have gone away. You can try it if you're having a problem and can't afford to get it fixed yet. Eventually, I'll have to get mine fixed properly, but in the meantime I have a chance to save some money to pay for it. Anyway, try the link below and see if it helps. Pat.
