What should I do about my dentist? I don't want a different one.?

My dentist keeps badgering me to get this crown or that implant even though I keep telling him that I can't afford it. Then, he badgers me to start saving my money so I can get my first crown in one year, a second crown the second year, and so on. I have temporaries instead of crowns. They last two or three years. I tell him I'll just get another new temporary, if necessary. He says that's not good enough. I have debts I want to pay off before I get the crowns and implant he says I need. He says, "You're health is more important than paying off debts". I have to have my teeth cleaned every six months, which is when he starts badgering me again. He is such an excellent dentist, and I do not want to change to a different dentist. But, enough is enough! Why can't he understand that some of his patients are not rich like he is!?
