Last month, I had both a front tooth filling and a back tooth cavity filling done during the same appointment. The process was smooth, and my dentist was great—but a few days later, I started feeling something I hadn’t expected: noticeable tooth sensitivity after the filling. Cold drinks, hot coffee, even just breathing through my mouthit all triggered a sharp twinge. I called my dentist, and they assured me it was common, especially with deeper fillings or if the tooth nerve had been irritated. They recommended a sensitivity toothpaste and avoiding super cold or sugary foods for a bit.
