I’ve been on the receiving end of two toothy disasters, first with a hockey stick to the face. It pushed one of my front teeth back in my mouth, severed the nerve and broke the jaw around the root. The dentist had to take the nerve out and root canal the tooth, then he splinted the tooth to the ones either side until the jaw fixed up and it was right as rain! until….
I smashed it out along with the one next to it in a silly clumsy low speed crash into a tree. Apparently teeth with root canal fillings are more brittle than live ones. This was all a bit more fundamental than the first time around.. loads of messing about with crowns, then post crowns, a denture then implants. Brutal amount of money but I’ve now got better teeth than when I started, silver lining and all.
fingers crossed its a simple/cheap fix for you!
