Hello doctor,I had a root canal five months back and it has caused a lot of problems. The root canal left a gap between the molar and the tooth beside it. Food got stuck inside and it was causing pain. I came back and she said it was the tooth next to my root canal which was causing the gap. Now that tooth had a filling in it so she offered to redo it so the gap would disappear. After the new filling, the gap was still there so she put some kind of hardening fluid in between the gap and told me not to floss on that tooth. A few weeks later and the gap is back and now my tooth with redone filling is very sensitive. I am starting to feel like this is a lost cause and I do not know where to go from here.
Hi, Welcome to Chat Doctor forum. Your case has become a bit complicated. It would have not gone this bad if the filling of the adjacent tooth would have been done before taking size for the cap, then the gap would have adjusted and you would not be having any food sticking complaint. But do not worry, there is an end to every pain and suffering. You might have to go for these stages of treatment now. First of all, an X-ray of the adjacent tooth that is feeling sensitive should be taken and assessed. The following could be the treatment options you could have. If there is some internal carious activity detected that is causing sensitivity and has not touched the pulp or root of the tooth, then again you have to go for deep filling with some regenerative  ChatDoctor.  If there is some carious activity that has touched the pulp of tooth then you would be going for root canal treatment and capping as done before. Then cap will be placed and it will fix your gap. You can have an option of capping at sensitive tooth after deep filling if caries has not reached pulp. Cap size will be adjusted to fill the gap and you will be relieved. It would be great if you can provide me with some of your clinical pictures of teeth and X-ray of both RCT treated and sensitive tooth. Then I could suggest better which option will suit you.
