Q. Hi, I only have 1 back molar tooth on the bottom rear (the 1 behind it & ahead of it had to be extracted). Are there any problems down the road if I don’t do anything about it – or should I be getting a bridge? I’m told a bridge will run around $3,000.00 but that’s a lot of money! Please let me know if there would be any problems leaving it as is? Thank you!
