Prior to the Affordable Care Act / Obamacare, you had up to 18 months of COBRA eligibility, meaning you could stay on your employer's plan but paid all premiums (expensive). During that time you frantically look for a job that includes healthcare coverage. Failing either of those, you might find junk insurance, or you simply go without and hope for good health. If your income is / remains low enough you might qualify…
I went through layoff six months ago. ACA definitely has helped with health insurance. If you are unemployed (no income), you are most likely to get subsidy as it is income based. Our premiums after subsidy is little bit higher than what we were paying when I was employed. I wish there was something similar to ACA for dental insurance. Most dental insurance plans on open market are expensive and with ridiculous terms…
It may be worth looking at how much you're paying each month in premiums and comparing that to the annual out-of-pocket cost for preventive / cleaning visits plus perhaps a filling or two. You may find that all the insurance is really doing is smoothing those payments out without saving you much money unless you have a "years of neglect" situation that you're still working through.
It's probably also worth asking your dentist if they have "self-pay" rates comparable to what they're getting from the insurance companies. If they bill $120 but accept $80 from insurance, will they take $80-90 cash from you instead of that $120? Also, for more expensive procedures like crowns, it's very likely that your dentist's office will let you do installments to spread the cost over at least several months. That doesn't really help when you don't have current income and aren't sure when you will have it, but it does relate to smoothing out your expenditures the way insurance premiums do.
