What is a root canal filling made up of?

Gutta percha: Usually gutta percha is used for endodontic treatment. The access can be filled with glass ionomer or composite.

Isonadra gutta: It is a tree sap. Isonandra gutta, a handsome tree native to borneo, java, and sumatra, is tapped to release a milky, rubbery sap that is concentrated to form the wondrous material known as gutta-percha. It is used for its soft property when heated which allows it to be stuffed into small spaces.

Root canal filling: Root canal filling consists of a sealer with either gutta percha or a synthetic cone within it. Sealers vary in what they are made from some being calcium hydroxide based, others zoe and some resin.

Gutta percha: Gutta percha has been the standard of care for a very long time. Now a new synthetic material (resilon) is being marketed as a better material due to its superior properties. The gold standard remains unchanged, but, resilon is showing promise as an alternative. Time will tell which is the superior material.
