Hi popo,

I just got some fillings done today. I have a couple of questions about this:

1) It took only a bit of novocaine to numb the upper part of my mouth, but it took a lot more to numb the bottom. I had to make the dentist stop and use more novocaine twice. So, why does it take so much more for the bottom?

2) Despite hitting the limit for the novocaine, I was still feeling some pain, so the dentist used a lower speed drill which was not as painful. Why are higher velocity drills more painful?

Thanks!
