Final answer:
Licensed dental professionals typically need to take courses in Infection Control, Law and Ethics, and Basic Life Support or CPR every two years to renew their licenses.
Step-by-step explanation:
All licensed dental professionals are required to complete specific continuing education courses as a part of the criteria for license renewal. These courses often include topics related to Infection Control, Law and Ethics, and Basic Life Support (BLS) or CPR training. While the exact requirements can vary by state, these three courses tend to be standard for ensuring that dental professionals stay up-to-date with current practices and maintain a high standard of patient care.
