Will there be a change in tooth color after treatment?

Yes, tooth discoloration can occur after root canal treatment. Tooth discoloration can occur due to the medications and materials used during treatment, the deterioration of the remaining pulp tissue within the tooth, or certain filling materials (such as zinc oxide-eugenol or mineral trioxide aggregate-based sealants). Over time, these materials can darken the tooth. This discoloration can usually be corrected with internal whitening treatments or a crown.
