Providing your Social Security Number (SSN) to your dentist is a common practice in the United States. It is used to verify your identity, prevent fraud, and for insurance purposes.
The Health Insurance Portability and Accountability Act (HIPAA) of 1996 requires healthcare providers to protect the privacy of their patients' health information. This includes their SSN. Dentists are required to comply with HIPAA regulations and take steps to protect your SSN from unauthorized access or disclosure.
