In college, I went to a dentist in Santa Barbara exactly as you describe--he even offered sugary beverages from a fridge when you left the office. I remember on my first cleaning he said I had 6 cavities! Up until that point, I'd only been to my local dentist and I'd never had any cavities. I ended up getting a second opinion from another dentist and he didn't think think I had any cavities. And here I am 20+ years later and I've still never had a cavity... I've had similar experiences with veterinarians...
