Based on the information provided, it appears that upper second bicuspid and third molar are the abutment teeth for 4 units fixed bridge. The second bicuspid appears to be afflicted with failed root canal treatment. The first consideration is if the second bicuspid is restorable? If yes, redo root canal or peiapical surgery may save the tooth. Seeing an endodontist is advised. Second consideration, third molar is generally not a good candidate for bridge abutment. Third consideration, it's a long span bridge, prognosis is questionable. Forth consideration, if opposing lower arch has second or third molar, the occlusion is difficult for most dentist to manage. In conclusion, if the second bicuspid and third molar are very solid, and lower arch has no third molar occlusion, if there is no second lower molar, it would be even better.the prognosis of fixed bridge is fair. You need to see a highly competent prosthodontist to proceed the restoration. Seeing an endodontist is also advised.

hi,Thanks for the reply to my question see my dentist in the morning and made an appt. with an endodontist but won't see me till the 25 of this month I am not sure of a redo will resolve the probelm as this tooth is not that great anyway and the  3rd molar has not that much there as the infection seems to be desapating the teeth still fill very tight  but the bridge feels a little lose so i am leaning to getting it pulled and get a partial upper denture also a partial lower since I am missing the 2 bottom teeth on that side but would an xray show if there was a break or crack in the root of the tooth and if there is a gap I just can't justify in my head to pay another 4 thousand and have it fail again just can't keep on affording this.Again Thanks

seen my dentist and prescribed me very expensive antibotics said maybe I had a crack in my tooth and it would mend back together still have 2 white very small bumps looks like still infection there(kinda small zit size)don't sound right to me that a crack in the tooth would mend its self still says the xray didn't show anything I have an appointment with endodonist the 22nd someone tell me the plain truth should I believe him or when I see the endo and they say it was a failed root canal should I chance it and have them redo or get it took out if it failed 1 time how can I be sure it won't fail again please HELP
