Hi Sadie, I just wanted to say I am sorry you are dealing with this pain. I know it is hard that your friends and family don't get how much pain can be caused by the tooth but know that there are many others in the same position as you and we get it!
I am finally getting a root canal tooth extracted tomorrow at noon after having 2 dentists and a root canal specialist tell me they want to keep treating it. The pain and cost are just not worth it in the end. I hope you get things sorted soon!
