Want to know pain?

If you ever need to know pain, do not take good care of your teeth. I had nagging headaches for weeks. Recently, eating become painful as my teeth get more sensitive. I went to the dentist and had a filling done. Thinking it is ok now, I had food and an intense shooting pain went right through my head. My greatest regret is not taking good care of my teeth. Pain is unbearable and debilitating. Back to the dentist again and found a bigger hole that does not show up in x-rays.
