A post and core crown is a type of dental restoration required where there is an inadequate amount of sound tooth tissue remaining to retain a conventional crown. A post is cemented into a prepared root canal , which retains a core restoration, which retains the final crown. After the preparation is complete the space that exists inside the root canal , called the post space , is available to place the post.

It is desirable to leave sufficient root filling material in the apical area to maintain an apical seal. Appropriate gutta-percha. While a dental core can be created for any tooth, a post and core can only be placed for a tooth that has already had root canal treatment. Posts can be made of metal or fiber-reinforced resin and are cemented in the canal space of the tooth to aid in replacing the missing tooth structure.

There are some cases when a root canal is needed when most of the tooth structure is able to be preserved.

The dentist then cleans and shapes the root canals to make space for the filling, and possibly, a post to support the tooth. The endodontist fills the root canals with a rubber-like substance. A root canal is performed when the endodontist removes the infected pulp and nerve in the root of the tooth, cleans and shapes the inside of the root canal , then fills and seals the space. Afterwar your dentist will place a crown on the tooth to protect and restore it to its original function. Post-root canal discomfort can be managed with over-the-counter medications such as ibuprofen ( Advil , Motrin ) or acetaminophen ( Tylenol ). Additionally, it is important to avoid chewing on the tooth until all of the tenderness is gone.

This will promote healing of the surrounding tissues. The pain shouldn’t last forever. The shape of the empty canal is then refined via the use of root canal files or a dental drill.

As a worst-case scenario, a perforation (a hole out the side of the root ) may be created. Very small instruments are used to clean the pulp from the pulp chamber and root canals and to shape the space for filling. After space is cleaned and shape the endodontist fills the root canals with a biocompatible material, usually a rubber-like material called gutta-percha. For that reason, in nearly every case, a crown or “cap” is used to protect the tooth and prevent damage. Crowns are usually placed in a second procedure, once your tooth and mouth have a chance to heal.

A post crown always requires a root canal to have been completed before it can be carried out. That’s because the post extends deep down into the root canal of the tooth in order to get extra grip for the core. This is unlike a pin, which simply screws a couple of millimetres into the dentine of the tooth to help hold a filling.

During mechanical preparation of the post space , the root canal filling material may be dislodged creating voids in the obturation and the filling material may be twisted or vibrated. In these cases, the swelling will subside in the days and weeks following the root canal , and the pain will resolve on its own. A root canal has two meanings: the first refers to the inner tooth situated between the tooth roots and the pulp.

The second refers to the tooth treatment aimed at the removal of infected material and elimination of a toothache.
