Root canals are needed when decay and bacteria spread to the inside of the tooth, attacking the pulp inside the tooth. Pain occurs when you feel the nerve being attacked or when the tooth is dead and bacteria starts to spread out beyond the tip of the tooth. Since all of this is happening on the inside of the tooth, you won’t necessarily feel discomfort right away, but pain can come on unexpectedly and quickly. We are here for you and always willing to help you to feel better quickly!
