A dental restoration treatment that is sometimes done after a root canal is called a post and core. During the root canal, an essential portion of the tooth is removed, and the post and core can help keep the dental crown in place. The dental crown is placed on top of the tooth to protect it from infection or damage.

During the procedure, the pulp-filled cavity in the root of your tooth is removed.
The pulp contains the connective tissues, nerves, and blood vessels.
In some cases, there may not be enough parts of the tooth that is intact for restoration. In this case, the post and core are performed to maintain the dental crown in place for reconstruction.
The root canal must be cleared of all original pulp-filled cavities, but the root must still be present.
It is recommended only to use the post and core procedure when more than 50% of the tooth’s original is removed. It should not be offered if there is not enough remaining tooth to hold a crown.
There are two types of post and core procedures: Prefabricated, a pre-made unit, and Cast when the one-piece unit is fabricated and custom made at a dental laboratory.
Pros – allows you to keep your tooth and eliminate the options for extraction.
Cons – do not strengthen teeth and may stress or weaken your teeth over time.
The post and core’s sole purpose is to salvage an existing tooth and help with restoration if the tooth has lost a significant internal structure.
