Extreme Sensitivity during filling

[Agonzalez]

I went to the dentist yesterday to get fillings done on teeth 20 and 21. He had to give me 4 different shots to numb me and even then I still felt extreme sensitivity during the procedure on one of them. It didn’t hurt but I was coming out of the chair because it was so sensitive every time he used the drill. Why didn’t the tooth respond to the numbing medication? The tooth wasnt infected, he said it had some decay underneath the filling that was already there. I’ve attached the sheet so you can see exactly what was done. Thank you!
