My teeth have been a problem for me ever since I was a teenager. I seemed to get cavities very easily, had some staining and, worst of all, my teeth were very sensitive to hot and cold. It was so bad that sometimes just breathing the winter air would cause a twinge of pain in my mouth.
Today the cavities have been repaired and thanks to a monthly whitening treatment, my teeth are bright. But until recently, I was still having issues with sensitivity. Cold was the big problem for me. I could sip a cup of hot coffee or eat a hot meal without a problem, but sipping chilled water or eating ice cream was close to unbearable.
