To become an oral hygienist, one typically needs to complete a two-year associate degree program in dental hygiene or a four-year bachelor’s degree program. These programs typically include classroom instruction and supervised clinical experience, and cover topics such as oral anatomy, tooth cleaning techniques, and oral health promotion. After completing an accredited program, individuals must pass a national board examination and a clinical board examination in order to become licensed to practice as an oral hygienist.
It’s worth to mention that some states may have different requirements for licensure, so it’s always best to check with the state’s dental board for specific requirements.
