Not exactly sure what you're asking but, you can already look at dentist's websites and see some information about their practice, and I imagine some have pricing for those services. That may not be what you are referring to.
What may be an option is this; it's like an discount plans for dental work, you can sign up for it online. I checked into it for a family member. Sorry, I don't think I'm allowed to put a link for them here. There are several, and thru reputable companies. There were actually several dentists in our town who participated in the plan. You pay a yearly fee, and for that you recieve a discount on dental services of all kinds. I felt it was very worth it myself. Prices around $100 year per person. They vary by company.
For instance on one was for an Adult Cleaning, usual: $75, plan: $39
Root Canal, Molar usual: $829, plan: $492
That name was with a large national well known insurance company.
That's just an example of 2 things, there are lots more. Even dentures. Some, I think Braces.
I have such a phobia about keeping my teeth, I'd probably look into anything to afford to keep my teeth healthy. But dental work is so expensive, a lot of people cannot afford it.
You can just do a search online for dental insurance plans and find quite a few. Wouldn't hurt to check into them.
