In order to practice as a dental hygienist, one needs a degree from a dental hygiene school and a state license. To become licensed, dental hygienists need to pass a clinical and written exam.
The State of California also regulates and licenses dental hygienists in the state. Dental hygienists must complete a 2 or 4 year training program and pass the Western Regional Examination Board (WREB) Dental Hygiene exam (written and clinical parts) before being licensed.
