Fluoride / potassium nitrate topical for Prevention of Dental Caries "I could only use this for a couple of days. It may say 'sensitive' on the label and be designed for helping reduce sensitivity, but it actually made a few teeth so much more sensitive I couldn't put ANYTHING in my mouth without causing excruciating nerve pain. Before it was just extreme temperatures causing a little twinge. This new feeling was so bad, even my tongue just touching the teeth caused shooting pain. I was able to calm the tooth back down through a miracle combination of Flonase and Sudafed to empty my sinuses and relieve any congestion from the cold weather, brushing with plain water, and finishing with a dry mouth rinse. Still hurts from an existing filling, but it's not as bad now."
