I’ve been having a lot of problems with tooth number 8. It started off with sensitivity to hot/cold. My dentist found a small fracture and did a bonding treatment. The hot/cold sensitivity went away but it was sensitive to biting down. And I noticed a lump high up on my gums where my lip and gums meet. Saw a specialist and it didn’t respond well to the cold test so I had a root canal 10 days ago. The lump is still there and my tooth is still sensitive to biting down. Does this mean the root canal failed?
