Posting for traffic really. My back molar is driving me mad. Two back cusps have broken off leaving the tooth sharp in my mouth. Dentist said it needs a root canal and a crown. Dentist has attempted root canal twice. First time one nerve in tooth was still ‘live’ and causing pain despite 4 lots of anaesthetic. He then put temporary filling on. Came back 6 weeks later and he couldn’t get the tooth numb! 4 lots of needles again. Put another temporary in. It’s fallen out twice and had to be put back in. It’s now fallen out again and back of tooth near tongue is sharp. What on Earth are my options now? Dentist talked about pulling it but it’s got long roots and curved roots so I’m really scared about that option. If they can’t get it numb how the hell am I going cope with having it pulled??! AIBU to be completely fed up with this tooth?!
