The worse thing about a 'Root Canal' treatment is its terrible reputation. That's because the 'root' cause of an undetected root canal infection often produces tremendous internal pressure and pain, beyond the point where anesthesia can be very effective. However, with regular dental visits and today's technology, catching and correcting a root canal infection early, is actually quite simple and painless. We simply identify the fact that a tooth's nerve has died, clean out any infection that's begun, and fill the resultant space to prevent further problems.
