When must a dental hygienist update a patient's medical history?

A dental hygienist must update a patient's medical history at every appointment or when significant health changes occur to ensure the safety and effectiveness of the patient's dental care. This practice is critical because a patient's health can change frequently, and these changes can impact the way treatments are administered or the types of procedures that are appropriate. For instance, new medications, changes in medical conditions, or the development of allergies can influence how a dental hygienist proceeds with patient care.

By updating the medical history regularly, the dental hygienist ensures that they have the most current and relevant information to make informed decisions about treatment and to manage any potential risks. This approach aligns with professional standards and promotes patient safety, highlighting the importance of comprehensive and accurate record-keeping in the dental field.
