When we perform RCT in a tooth, the Pulp is removed, the Pulp contains Nerve & Blood vessels, and after that tooth becomes dead becomes weak.

Generally, pulp gives nutrition to the tooth, when we remove the pulp the nutrition of the tooth is stopped. So after RCT tooth becomes brittle & tooth can easily fracture.

At this time Dental Crown add support to the tooth which helps to protect the tooth from getting damaged. That way  After Root Canal Crown placement is very important.
