Dentists use portable dental units to provide exams, extractions and restorative care. Hygienists offer oral hygiene education and first time cleaning for children. Essential to a successful clinic, non-medical volunteers manage the lines of patients, assist in record keeping, keep track of children and help with instruments and charting. Volunteers are moved by the sense of service, and by how much more they receive from the children themselves. Following the clinic, volunteers may join an optional trek or cultural tour of local sights.
