My husband has a bridge (rugby accident... yikes), and you literally can't tell. When I look at him, I honestly have no idea which tooth it is. However, he went to one of the top cosmetic dentists in San Francisco to have it done, and it cost a fortune. He also had to have gum surgery so it would look natural with his bridge. :(
More recently, he had a tooth break right at the gum line, so they couldn't cap it. This time, he opted for an implant. Now, that wasn't cheap either, but it functions and looks just like a real tooth, and will last his whole life. As you know, bridges can complicate your dental care (for instance, if you have to get a filling on one of the supporting teeth, you can end up having to replace the bridge, which is no fun). So... if you're thinking of getting a new bridge, you may want to ask about implants. The process is pretty long to get them (they have to place the post, and then the jaw has to heal completely, which takes about 2 months). But you'd never have to worry about them again.
Good luck. Dental care is so expensive, and so little fun. :-/
