Funny. > I strongly prefer 5 to 10 somewhat inconvenient minutes over having a numb jaw for a whole day. I am not sure you'd say the same after 3-4 hours of treatment. I've done some root canal treatments here and there, which can take a long time. I'll take a numb jaw for a couple of hours afterwards over being in pain for 3 hours. But I guess you're right, for 5-10 minutes of pain, it isn't worth it.
