Should i go to a general dentist or a endodontist for a root canal?

Either: This all depends on the complexity of the root canal treatment and the skill, judgement and experience of the general dentist performing the procedure. A general dentist can do these procedures if they have continued extensive training in endodontics and have developed the skill and judgement over time.

Either: A general dentist often can do the root canals, but many don't want to anymore. They may refer you in some instances if the dentist feels that the root canal is best done by a specialist. Decision often is made depending upon the difficulty and time management.

Go to someone good: It doesn't matter whether you have your root canal treatment done by an endodontist or by a general dentist. What matters is their competence. An endodontist has more formal training. However, there are plenty of incompetent endodontists, and plenty of superior general dentists who can deliver great results. See a reputable dentist you can trust, and they'll recommend a course of action.
