Hello According to the picture, there is enough to structure, so maybe there is no need for post

I undertand your concern , based this xray post is not necessary i think , but its just one sided view , the buccal view could have been possible to asses with a clinical picture. and based on my fellow dentist's suggestion i blv post wud hv b necessary . in that case yes, one post per root makes it 3posts. for which the charge varies. may be you can take a second opinion from another dentist if cost is bothering you

Hi we can't say exactly whether this tooth requires post or not it has to be examined clinically also

Talking about charges, we cannot comment on the charges. You can get a crown/cap after RCT. Post is not necessary.

Not necessary. Your tooth has definite structure which can be left normally as it is. You should go for crown after RCT.

No need of post

In which city??
