Disclosed is a method for filling a root canal in a tooth. The method includes positioning a fiber in the root canal of the tooth, filling at least a portion of the root canal with an unset hydrogel composition, such that the unset hydrogel composition contacts at least a portion of the fiber, setting the hydrogel composition, thereby forming a set hydrogel, and removing the fiber from the set hydrogel, thereby leaving a channel in the set hydrogel. Methods and kits for repairing teeth are also described.
