Wow this is so good to know. My DH is a gagger and can hardly get thru x-rays. He usually ends up throwing up, at least once, when getting a cleaning. Needless to say getting him to the dentist is like pulling teeth. Baahahaha!
Oh My God. I just remembered one child we had in our office for a cleaning. She was fine until the first rinse, when she realized the pumice was gritty in her mouth? She barely got out the words "it's sandy" before puking all over the hygienist. Next visit, salted her.
