I get that many people fear the dentist, but it never is a number that is so great that it takes a toll. I like to think that for every tough patient that will ruin your day, you'll have one patient which will make you love it.
if you're getting so many patients who hate coming to the dentist, figure out why that's the case. are you working in an area where more people are coming for emergency treatment rather than preventative care. are you having trouble calming down nervous patients? can you add benzos to your management? are you taking the fear people have of the dentist in general too personally? I find that I still keep in touch with a lot of my dental classmates and we talk teeth all the time. This topic has never come up though.
