Well I've never been offered it even as a kid who HATED going to the dentist and made a lot of noise about it. I probably made the noise to my mum and not the dentist, come to think of it, so that can't have helped. But when I went private for my latest round of treatment I had hoped it would be on the menu along with the video specs and paraffin wax hand bath. It was not. So I had to load up on grey market benzos and opioids.
