Hi...its not always necessary to giv crown for rc treatd tooth....but it depends on the remaining tooth structure..if its a weak tooth definitly u need a post n  crown...ther are other options like overlays ,in which remaining tooth z preserved instead f cutting it..can be done in posterior tooth....everything depends on the tooth number n position...cant do overlays in front tooth...

Depends what size of decay was to start with If tooth was decayed a lot, you certainly need crown Else tooth may fracture , so rct ll be a waste

Hello mam....    Your Root canal treated tooth is more prone to vertical fracture of root  and will brittle if not properly capped by crown..Also it may cause food lodgement in that area which too cause affect fillings of root canal...so ,It is mandatory to cap Your RC treated tooth with crown...

Crown protects the RCT treated tooth in multiple ways. It protects from getting fractured, filling dislodgement and food obstruction. So go for a crown.

It depends on tooth decay and width of canal. If tooth decayed more and width of canal is more then you should instantly go for crown. Likelihood rct tooth should covered with crown,because rct tooth become brittle. Tooth will fracture easily.

This is mandatory to place a crown over rct tooth otherwise tooth will fracture in future.

its very important to get crown on rct treated tooth because after rct tooth become brittle so it may break
