Step-by-step explanation:
In most states in the United States, a dental hygienist must be at least 18 years old to practice. This is because dental hygienists are licensed healthcare professionals who assist dentists in providing oral care to patients. Being 18 years old or older ensures that individuals have reached the legal age of adulthood and are capable of making responsible decisions in their professional practice.
It is important for dental hygienists to meet the age requirement, as they may encounter situations where they need to make critical judgments about patient care. For example, they may need to assess the oral health of a patient and determine the appropriate treatment plan. By being of legal age, dental hygienists are more likely to possess the maturity and experience necessary to handle these responsibilities effectively.
Additionally, some states may have additional requirements for dental hygienists, such as completing an accredited dental hygiene program and passing a licensing examination. These requirements vary by state, so it is important to check the specific regulations in the state where one plans to practice.
