When I was about 10, I needed a lot of work on my teeth. I had always brushed my teeth, I couldn't understand the problem. The dentist gave me a shot and started to work on my mouth, I jumped out of the chair. He asked what happened, I said I felt it! He thought I was over reacting, but gave me another shot. I ended up having four shots to get the work done. Every time I have dental work done, I end up needing four shots. Yet I never use it for the cleaning. I have had fillings and root canal and as long as they give me four shots, it's a go. My jaw gets so sore, I need to take breaks or it is unbearable for days after. I need work done on my teeth now, but I can't afford it. Hopefully, I will be able to soon. My two sisters had braces, my brother and I never needed them, but we've all had problems w/ teeth thru the yrs.
God bless. Alice.
