Bad Time and confused!

I am a 20 year old college student that has been going to the same dentist since I was 6. Growing up I had no problems with any dental work being done because my dentist did a good job in making sure I was comfortable. For example he always hid the needles and explained what he was gonna do when he did it. But this last time I went to the dentist I must say it was the worst experience ever and it makes me never want to go to the dentist not even for my 6 month cleaning. I went in because I had a filling to crack and fall out and I needed it replaced. Well my dentist saw some tooth decay. So he determined that a refill was necessary. To begin the procedure the dentist numbed my mouth. When he came back he began to drill my tooth and I felt it. Startled I jumped and he stopped and gave me more numbing medicine. And i didn't feel anything. Its been two days since the procedure and my mouth is sore and it feels like I have a sore in my lower jaw. What should I do?
