I want to change my work place for children's stomatology. I think it is very specific. And almost all children are scared. They can cry and resist. What is the most typical to calm them? Or maybe not typical but works?

In one job description I've read that you can become dental nurse even if you don't have experience. Is it true? They mean experience in medicine at all?

Dental Nurses normally work with dentists and other oral hygiene professionals providing care to patients and providing the administrative support to their organizations. Among other responsibilities they manage patient’s appointments and records, prepare surgery material and sterilize it after being used in procedures, operate suction devices during treatment, prepare materials and compositions e.g. fillings, perform material stock control.
Dental Nurse might work in private practice clinics or public health organizations and hospitals.

• Building a relationship with patients
• Managing patients appointments
• Making sure all equipment is sterilized and ready before procedures and treatments
