$2.5k for a Molar

to save or not save? seeked a second opinion today after my toothache bothers me so much the past weekend.. the dentist still tells me the same thing.. that my wisdom tooth is causing all the pain and needs to be extracted asap, and to save my molar either i do a root canal procedure or extract it out as well.  To do the root canal will costs $2.5k.. is it worth it?  sooner or later, we will all go 'boh geh' so is it worth it to spend 2.5k on a molar now? or have it extracted and become boh geh sooner?  i am in a dilemma.. actually i am more worried about the procedure itself, need to complete the procedure in 6 different times, means i have to see the dentist for 6 times before the whole procedure will be completed.  This is what really puts me off actually.. and even though i know i need to extract out my wisdom tooth via surgery i am still delaying it.. because the entire surgery will take 45 min to an hour and my mouth aches even for 5 min for opening too wide for too long.. how to tahan 45 min??   I hate going to the dentist!
