How much does a dental bridge for one tooth cost?

800-1500, depending in location and geographical location of the lab that makes the bridge.

I had a 5 unit (3 abuntment, which is anchoring teeth, and 2 false teeth) bridge installed back in 2006 and mine cost ~$700 per tooth. When all was said and done I think mine cost around $3600. I'm sure prices have gone up. Remember though, that even with one tooth, they have to use a tooth on both sides to anchor it. It's the same concept as a bridge on the road. You have land on two sides followed by the bridge. I would expect at least $2000. The best thing to do is call several dentists in the area and explain what to need and just ask for an estimate so you will have a general idea.
