I have no pain so tooth is dead I presume. My dentist just retired and I have seen new one about this and another problem . She spent a while talking about the other problem on other side of mouth and I am having root canal treatment today for it. The dead tooth with missing filling one she dismissed and said ..no hope might as well extract or words to that effect.
I would rather not lose the tooth tbh and wondered if I was being unrealistic.
Dentist here. Agree a second opinion can do no harm. I've not seen you so cannot advise fully, but teeth that are too broken down to get a good result on root canal and a crown are usually best removed due to risk of ongoing infection.
