What is the appropriate response when covering for a dentist and a patient reports a toothache?

Scheduling an appointment for a limited exam is the appropriate response when a patient reports a toothache while under the care of another dentist. This option demonstrates proper dental ethics and patient care, as it recognizes the patient's need for immediate attention and offers a proactive approach to their concern.

By scheduling a limited exam, the covering dentist can assess the situation, determine the cause of the toothache, and provide necessary recommendations or treatment. This approach not only addresses the patient's discomfort but also ensures continuity of care and maintains the trust the patient has in the dental practice.

The other responses do not adequately address the patient's needs or the ethical responsibilities of a dental professional. Advising the patient to wait until the original dentist returns fails to attend to the patient's immediate concern, which is not in line with the standard of care expected in dentistry. Ignoring the call disregards the patient's need for support and can lead to further complications, while suggesting the patient go to an emergency room is unnecessary and may not be the most efficient method to deal with a dental issue that could potentially be handled in a dental office setting.
