@donna61--Depending on the type of bridge and how much dental preparation determines the cost. Usually, you can figure on five hundred dollars up to nine hundred dollars per tooth.
Check with your local dentists, some of them will work with you on a sliding scale, ours did.
Also, a part of the bill might be covered by your insurance plan if you have cosmetic dentistry as part of your coverage. Any remaining balance would be your responsibility. I would call and ask your insurance carrier if they cover cosmetic dentistry.
