How long must a dentist retain patient's dental records beyond the time that the dentist has last treated the patient?

The correct answer is that a dentist must retain a patient's dental records for seven years beyond the last treatment date. This requirement is consistent with Minnesota state law, which mandates that dental records be retained for a minimum period. Retaining records for this duration is essential for various purposes, including potential legal disputes, continuity of care, and compliance with professional and regulatory standards.

After the seven-year period, dentists may opt to destroy the records, provided that they follow any specific protocols for preservation or destruction that may be outlined by law. This timeframe reflects a balance between the practical needs of dental practices and the rights of patients to access their records even after they have received their last treatment. Being aware of this retention requirement helps ensure that both dentists and patients fulfill their responsibilities related to record-keeping and access to dental information.
