True... tooth decay isn't something that goes away. Could have been cold or heat sensitive.
To finish my story, I had a choice between root canals and caps or extraction. I just let him pull them. I don't think I could afford the other option. I have one more to go and I'm hoping that one will be filled. I was shocked when I found out the cost of pulling a tooth. I can only guess what a root canal and cap would be.
