Root canals get a bad rap. We ask that you don’t believe the rumors; the dreaded root canal isn’t actually dreadful at all! Root canals are needed when either decay or an injury infects the inner tooth (the pulp). In the earliest stages of infection, you may not feel any pain at all, but when it progresses, you could experience swelling or the formation of a dental abscess. Root canals remove the infection and prevent it from spreading. Thanks to laser root canals, this process is faster, more comfortable, and, in many cases, more thorough than conventional root canals. Pulp capping is an alternative to root canals that is used when the infection has yet to penetrate the pulp. Pulp capping can also prevent a large dental filling from getting too close to the nerve.
