W:What does it look like?Am I all right?
M:Well There is definitely one hole.W:How did that happen?I brush my teeth 3 times a day.
M:Don't worry.It's not your fault.Holes are just a natural occurrence for most people.I'd like to take x rays of Your mouth to see if there are others.
W:How long will that take?
M:Oh It should just be a few minutes.We'll try and get them filled before you leave today.
W:Does it hurt much?
M:Oh,no,don't be scared.It's not going to hurt.and It will only take an hour or so.
W:well Okay.But can you put me to sleep first?
M:That's totally unnecessary.I'm telling you it won't hurt that bad.Besidesthe medication that it takes to make a person unconsciousis more dangerous than the minor attention your whole will require.
W:I'll try to bear it,but i'm very scared of the pain M:That's natural.But I promise youthis should be very easyand in the long run.This is definitely the best thing.If you wait till later,it will just get worse.
W:All right.I suppose you know better than I do.
