I am not questioning that I need a root canal, I am fine with that, I am just wondering if a crown is really necessary. I am from Brazil and talked to multiple people that did root canals there and none of them got crowns, it’s not very common practice there unless your tooth is really really bad, they usually just do a regular filling. I am living in the US so I am thinking this is a little weird (plus I didn’t get a good vibe from my dentist’s office/the staff is kinda unprofessional). I have no pain right now so I am looking into my options. I asked for them to send my x-rays in case I wanted to see another dentist and they sent me only 6 (I was told by another office that usually they should do more than that).

X-rays: https://imgur.com/a/GqrtjJK (they fixed the little cavities already, the root canal and crown would be on the last tooth on the right superior side)

Can they tell by only looking at this that I need a crown? I don’t want to seem stupid and I regret I didn’t take better care of my teeth but also I want to make sure I really need to do this (not a financial issue, just trying to understand).

Thank you!
