I think dentists have improved all round since I was a kid. They definitely seem to have an emphasis these days on making the patient feel at ease as much as possible and reducing any pain, discomfort, etc, as much as they can.
A far cry from the dentist I went to age 10 who stood in front of me with a large needle and said, "This is going to hurt like hell and it's your own fault for not brushing hard enough." It did, too.
Somehow, that induced a fear of dentists in me that lasted until just recently. Go figure.
