Three years ago, I had root canal work on #19 and a crown.  I am now experiencing some pain in that area.  I went to the dentist and he referred me to an endodontist.  My problem is I cannot afford 900.00 to have this tooth redone.  I understand that the entire process of having the crown removed and redone must be done and it is a very expensive procedure.  What else can I do?  Can the infected root canal be treated?
Should I have the tooth removed altogether before it becomes very painful?

Dr. Asensio:A tooth that had root canal treatment in the past and is reinfected can be retreated. However, retreatment long term success is lower than the original 90 to 95%. If you can get it done do it. Your own tooth is better than no tooth at all and it beats the alternatives in longevity and cost. For example the best alternative is an implant to replace the lost tooth . This is several time more than the cost to save it. Keep in mind that i do not know why it failed in the first place. This should influence your final decision. I would suggest for you to go and consult with the specialist( Endodontist) to see what he would suggest once he/she sees your particular situation.
