hi,
recently had a pre root canal treatment on my tooth. it started throbbing/pulsating really bad in the night. the dentist drilled, killed the root and used a dental broach for something. he then patched me up and said to come back within 6 months or so for the root canal when i have raised some funds to pay for it lol.
2 weeks on and my tooth is still causing me transient pain. worse when i bite down and release. it isnt red, it isnt bleeding and there isnt any swelling there. both nerves are certainly dead according to him. why would this be?
