Toothident is more likely to be recommended by 4/5 dentists if it is much better known than the best toothpaste, and advertising achieves that. Edit- Also dentists are not necessarily particularly rational. I know a dentist who told me that she rejects evidence based medicine and thinks that we should use traditional Chinese medicine instead. She isn't Chinese, she is a British middle-class hippy and when I asked her about the effect on rare species, she said that rare species are never used in Chinese medicine. I then asked her if she supports evidence based medicine when her patients are anesthetized, or does she think the dosage should be guessed and she said she didn't know what that had to do with it. Also, 5 is a tiny sample. From a sample of 5 dentists, 4 might tell you that the second coming of Christ is imminent, but that would tell you very little about either Christ's travel plans, or the opinions of dentists.
