I know about MUSC. I looked into them early on. They charge $275 to walk in the door of the dental school. Price tags rapidly increase from there. In general MUSC is savagely expensive for anything. If you so much as walk in there and say hello you'll walk out with a bill for $10,000. I had a seizure several months ago and ended up unconscious in a parking lot. I was ultimately taken to MUSC. I basically laid in a bed there for 3 days. No surgery or anything like that. They sent me a bill for $50,000. I laughed. They may as well have sent a bill for 800 billion.
I've worked in two different fields. At times as a tech in electronics at the industrial and manufacturing level, mostly in designing and building communication systems like broadband networks and satellite communication systems. And there were times that I worked in media production designing graphics, animation, 3D models, building sets and props, video/audio production, and web design.
At the moment I work for a small business as a tech consultant for solar power installations and energy monitoring systems. Low pay and no benefits. I make it a goal to apply for a job every day. I monitor job posts daily. There just isn't a whole lot going on right now. Well, there are tons of job postings but most pay even less than I make now. If I could get a government job I would take it asap. I've actually applied for one recently.
I looked into dental insurance and it seems to be mostly a scam. You pay for insurance that doesn't really cover any actual dental care.
I know there are risk in the DIY route, but as far as I can tell it's either that or nothing.
