Well. I've contacted a few dentists, and I've begun to look into this thing called carecredit.
Don't do credit cards or ask for loans for that kind of work. That's the worst idea. Credit cards will ruin your credit, even if you make minimum payments each month. Not many people know that only making minimum payments can negatively affect your credit score. Besides that, with interest rates so high, both will only end up costing you more in the long-run. Ask your dentist about a payment plan. Most dentists in the US offer payment plans for people who can't pay it all off right away.
I'm going to have to respectfully disagree, at least in part, with this.
Ever since the advent of "Care Credit" a lot of dentists here in the United States are no longer willing to work out direct payment plans with their patients, but they do accept Care Credit. Which is rather understandable. Dentists are not in the loan-business. They have their own expenses they have to pay and having a lot of outstanding accounts-receivable can harm their cash-flow.
The advantage of Care Credit is that, IF you pay off your balance within the prearranged time, there are NO interest charges. (That time will vary based on how much is charged.)
For example, I recently charged a dental bill of $200 to have a tooth bonded to my Care Credit card. That amount qualifies me for a 6 month interest-free repayment plan. However, my minimum monthly payment was set at $25. Now, obviously, if I only paid $25 each month, I wouldn't have it paid off within my six months, and I would have gotten hit with quite hefty interest charges. However, I paid $100 each month for two months, and didn't pay any interest.
The caveat here: make sure you don't charge more than you KNOW you'll be able to pay off within the prearranged time-frame as, if you fail to do so, the interest charged will be at a very high rate, and will accrue from the date of the charge, not the end of the grace period.
I do understand that, once you've decided to take the plunge and get this work done, you want to get it finished as soon as possible. But everything takes the time it takes and I'm sure there are priorities here, as well as other things that don't have to be done immediately.
"Free" dental clinics are a possibility. I have to put "free" in quotes because they usually aren't completely free. But they are a darned sight cheaper than a regular dentist. Dental schools are also a great possibility.
I don't know what state you live in, but you could look here:

Please keep in mind that "Rome wasn't built in a day" so it may take you a while to finish getting all the work you need done. But be proud of yourself for having made a start. You WILL get there.
(And stop beating yourself up about this being "all my fault." What's done is done. What's important now is that you're moving forward and getting help.)
