Prescription Fluoride Toothpaste was a life changer for me. The tube is like $20 but lasts about a year (you don't use much). It took a few months of nightly use, but It drastically changed my cold sensitivity. I can bite into ice cream and popsicles now, something that always hurt as a kid. You also might want to consider a different dentist, as there is a large range of ability with them.
