Here's mine: Gel Kam. Gel Kam is available in most drugstores for sensitive teeth. A great product!
I was having pain in a tooth and saw my dentist. He can't take x-rays because I've had brain tumors so he bangs on my teeth and pokes around with sharp instruments to try to locate the pain and see if it is a cavity or not. I DREAD the dentist!
Long story short, he wasn't sure what was causing the pain and recommended Gel Kam. It worked like a charm. Pain is gone. CP is happy!
Post your great but little known products!
