Is dental crowning after a root canal necessary?

Read this

by John I Ingle - “crowns should be placed on endodontically treated posterior teeth that have occlusal intercuspation with opposing teeth of the nature that places expansive forces on the cusps. Since crowns do not enhance the clinical success of anterior endodontically treated teeth, their use on relatively sound teeth should be limited to situations where esthetic and functional requirements cannot be adequately achieved by other more conservative restoration”

Meaning in simple terms

If RCT is done In Posterior teeth i.e 2 Premolars and 2 Molars and

if they have opposite teeth, then you must get a crown after the Root Canal, otherwise due to force by opposite tooth RCT treated tooth will fracture, and then it will be a waste of your time, money, and doctor’s time.

if there is no opposite tooth then you should not because then there will be no force on the RCT treated tooth.

In case of RCT in Anterior teeth i.e canine, lateral incisor and central incisor. There is no need for a crown in them until and unless there is esthetic demand by the patient or functional demand by your teeth.
