I did some searching on your question and found a good web site that may answer most to all your questions about bridges. I took a monet to copy a little of it and have listed the link below.
How much do dental bridges cost?
The average cost of a single fixed bridge depends on many factors, from which region you’re in to how many and which type of bridges are needed. Typically dental bridge cost ranges from $500-900 per tooth. Dental insurance typically pays for about half of the cost of the bridge. This is a cost per tooth in the bridge, and doesn’t include the costs for any anchoring crowns on either side of the bridge.
If you do not have any dental insurance or plans to help with the cost of having a bridge, then I have listed a web site that may help you with that.
