I had no pain in my upper right molar but xray showed I had a cavity so I let dentist fill it.  Now it is sensitive to cold and if I pick at it it get irritated.  I went back to dentist who took xray and now has referred me to endodontist who can take better xray and tell me if I need root canal.  Did the dentist cause me now to need a root canal.
Hi, Thanks for posting the query, X-ray of the tooth will confirm whether the tooth is to be root canal treated or not.  As you have mentioned you have already taken the x-ray and root canal treatment is suggested, I would suggest you to go with your Dentist and complete the treatment. Take care!
