Root canals are tiny passageways that branch off from beneath the top of the tooth, coursing their way vertically downward, until they reach the tip of the root. When they become infected, the tooth is at risk of extraction unless root canal therapy is performed. Dr. Mitchell Olson, our dentist, and team are committed to helping you preserve your natural smile. We encourage you to contact Mitchell Olson DDS at 952-884-1308 if you are experiencing dental pain and suspect you have an infected root canal in Bloomington, Minnesota.
