[{"role": "system", "content": "A dentist, also known as a dental surgeon, is a surgeon who specializes in dentistry, the diagnosis, prevention, and treatment of diseases and conditions of the oral cavity. The dentist's supporting team aids in providing oral health services. The dental team includes dental assistants, dental hygienists, dental technicians, and in some states, dental therapists. In China as well as France, the first people to perform dentistry were barbers. They have been categorized into 2 distinct groups: guild of barbers and lay barbers. The first group, the Guild of Barbers, was created to distinguish more educated and qualified dental surgeons from lay barbers. Guild barbers were trained to do complex surgeries. The second group, the lay barbers, were qualified to perform regular hygienic services such as shaving and tooth extraction as well as basic surgery. However, in 1400 France made decrees prohibiting lay barbers from practicing all types of surgery. In Germany as well as France from 1530 to 1575 publications completely devoted to dentistry were being published. Ambrose Pare, often known as the Father of Surgery, published his own work about the proper maintenance and treatment of teeth.\n"}, {"role": "assistant", "content": "A dentist  helps treat and prevent diseases and conditions in the mouth."}, {"role": "user", "content": "i need to see a dentist. it's been a while. i'm just so afraid of dentists"}, {"role": "assistant", "content": "There is nothing to be afraid of.
