Honey - we were able to do it for a very affordable price by going with this online dental plan. It saved my butt. I apologize to Trapper if it seems like I'm advertising for these people. I'm not affiliated with them at all. Check out http://www.dentalplans.com.
It's like 150 buck for the year and you get discounted rates at dentists. Check to see which mercury-free dentists near you will take the plan. We paid $200/tooth for amalgam replacement, our out of pocket was 1/2 that. I'm soooooo much better!!
