    In instances where the root canal access cavity is small, it may be possible to restore the tooth with a simple filling.

    This is often the case for front teeth (upper or lower) that have required root canal treatment but are still largely intact (are not broken or fractured, didn't have extensive decay).

    A dental crown provides its protection by cupping over the tooth, thus acting as a splint that holds it together.

    It also distributes forces directed to the tooth more evenly.

    If a very large portion of the tooth has been lost, the dentist may need to place a "post and core" before placing the crown.

    A post and core serves as a foundation that helps to anchor the crown in place.
