Hi Penny,
So sorry to hear about your problems and I’m not sure what to suggest. Is there any way you can get a second opinion from another dentist at the veterans hospital or elsewhere, or can you talk to your current dentist about your concerns? At the very least they should be able to remake your crowns so they look more acceptable and should explain why things have not gone to plan, and how they intend to treat your dental problems so you know what to expect in the future.
Sorry not to be more useful.
