I got a filling in an upper wisdom tooth 9 days ago. I have had a dull ache on that side off and on since. I have also had a couple of times where my tooth seemed very sensitive to cold. It hurts a little to chew on that side. Sometimes the pain seems to be coming from at tooth two teeth down. I have great teeth, only three small cavities before this for 57 years. When the filling was done, the tooth was not numbed properly at first and it hurt a lot when he first started drilling--he had to inject more anesthetic. Is this something that will get better over time?
