Prayed, praying, and will pray. I am NO stranger to Dentists and teeth problems.
In Marine Corps Boot Camp, I received a root canal a week while there. I had great dental care when I was a kid, and I had one tooth that had a problem going in. I still have a difficult time believing I had as many teeth that needed root canals, but it was not for me to question why.
Years later, I began having problems with every tooth the Navy had worked on, and my current dentist was shocked. He said they left bits of tools in my canals, and that he had to re-do every root canal I had done while in the Marines. Thankfully, I had great insurance, and was able to have all my teeth repaired, but oh....OH.....what a mess,and what a painful time.
I said all that to say, I'm with ya, and I empathize with you, and yes, my prayers are with you.
