Under the supervision of a dentist, a dental hygienist or a prophylactic dental assistant provides professional hygiene treatment. Both these professions have received adequate
training. These treatments should be done at regular intervals, the frequency varying from 4 months to a year.

Your dentist will be in charge of the billing.

Nowadays, you will find dental hygienists who work indepedently; they work in their own office, and they are not allowed to do anaesthesia. (X-rays?).

Their bills should be detailed, mentioning the position number according to the SSO tariff.
