The three best reasons for not visiting a dentist are getting tired, feeling uncomfortable and being unhappy while having some dental-care. When a dentist gives treatment to my teeth, I have to open my mouth wide like the front door of a bus. This makes my jaws stuck and unmovable for a while. One hours of treatment seems like twenty tedious hours for me. Also lying on a dental chair is like sitting on an electric execution chair. The noise of all dental equipment is as horrible as the sound of machine in a slaughterhouse. Wondering which appliances will be put into my mouth makes me nervous all the time. Furthermore, I had a very bad experience of visiting a new dentist five years ago when 23-year-old novice pulled one of my left decayed molars out. Then I was not able to talk or open my mouth for three weeks. Without doubt, if it is not necessary, I will avoid visiting a dentist entirely.
