Well I am having trouble also with a tooth, I tried everything, quit using fluoride toothpaste for already 6 months, using soap on a daily basis , baking soda for neutralizing acids and still the pain is gettng stronger and strognger so I have to go to dentist in 2 days. He will try to save my tooth with laser so I will not get a root canal.
I already have 4 root canals and I am 32 yo. I guess nothing will ever work, you ust have to accept the fate.
But try to go to laser dentist usually with laser there is not necessary to remove too much teeth structure.
So I am doing that.
I am so scared that I wil get a root canal. And I do not want to pull it out also.
