If you're really into a dentist that likes to socialize, then he is perfect, otherwise, I feel like a lot of the time is wasted by small talk and conversation that is unrelated to dentistry or the patient. It's probably his way of trying to be personable but a lot of times, that overshadows the real reason why you would go to a dentist--to get cleanings in a thorough and comprehensive manner as well as assessment of your overall condition. When he does the cleaning, it's always in a hurried manner like he's just doing it to get it over with. I had a cleaning that was done in 15 minutes! My previous hygienist usually spends about 45 minutes for cleaning and she is very thorough. I moved so could no longer use her.
About Hygienist: He does the cleaning himself, the office reception also plays the role of a hygienist assistant.
