"Does not work on dirty teeth", in the dentist's own words. What, then, is the point of a dentist? If one's teeth were constantly fresh, clean, and pristine, a dentist would be a pretty superfluous thing, wouldn't it? It just seems to me that a dentist who won't work on dirty teeth is something like...a racecar driver who won't drive in a car with wheels. Neither of them will perform their profession in any way that can be mistaken as adequate, and more to the point, their performance can be mimicked by any person with a pulse. You know, because they aren't actually doing anything. To sum this up, dentist is poor, although I have no proof of dentistry. I can do as good of a job without any sort of degree, since it takes no schooling to tell someone that you refuse to do your job.
