I think my dentist sees me as a bit of a cash cow. I'm part way through having 4 crowns and 4 implants (separate teeth) done.
I've said no to a couple of things, like I have a big old gold crown on a tooth which isn't bothering me but he can see one of its roots has infection he can see on X-ray. He wants to change it for an implant just because it needs changing. I forget how much that one would cost but I'm more concerned about the time it takes. It's months per tooth, usually he has to add artificial bone which takes time to be assimilated. I've told him I've got enough being worked on so he has to wait until I have more properly working teeth. He thinks "why wouldn't you want them fixing?". My response - "cos I can't be assed."
A denture probably beckons at some point, or I'll have a gap, soddit!
