My stupid tooth

 UGH 
What to do?

I have a tooth that has a crown and is running cold-sensitive and a little pressure-sensitive.

My dentist thinks I should have a root canal (through the crown) before surgery. She thinks the nerve may be dying.

I saw a specialist endodontist yesterday- he painted the root with a desensitizer and gave me an Rx for extra strong sensitive teeth toothpaste. He said sometimes you can have a little gum receding on the crown and have sensitivity. He also said my x-rays absolutely did NOT show any infection. 

If I need it done, he could do it Monday, but I honestly would rather wait till maybe 2-3 weeks after surgery. 

I'm afraid if I talk to my surgeon about it they will cancel my surgery or push me back another week, and I just want to get the damn cancer OUT of my body ASAP.

So I feel like I'm going to cross my fingers and if it gets crazy bad in the week after surgery I'll just deal with it. Really hoping the special toothpaste will calm it down. 

In other news, all my blood tests and pre-op tests came back and looked good (to me says the medical technologist/laboratory scientist). 

Might make some chicken soup today and hoping to go to Temple tonight.

Update: on tooth- followed the very kind dentists advice and my tooth has calmed down !
