The Saturday Emergency and the Unlicensed Assistant
Dr. Chen practices solo in a suburban office. On Saturday morning a patient calls with a swollen face, fever of 101.8°F, and difficulty swallowing after a lower molar extraction three days ago. Dr. Chen is out of town and cannot return until Monday. His only staff member on call is Marcus, a dental assistant with six months of experience who is not certified in radiography and has never placed or removed sutures. Marcus offers to "open the office, take an X-ray, and pack the socket with dry gauze" so the patient has somewhere to go. The patient has no primary care physician and asks whether Marcus can just prescribe an antibiotic.
1. What scope-of-practice limits apply to Marcus if he goes to the office?
Read the worked answer
Marcus may perform only delegated duties within a dental assistant's scope and only under the required level of supervision. Taking radiographs requires the appropriate radiography certification/permitting in Texas; he is not certified, so he may not expose radiographs. Diagnosing the swelling, prescribing antibiotics, or performing surgical procedures such as suture placement/removal are outside his scope entirely. Packing a socket with dry gauze as a temporary comfort measure may be permissible as a basic first-aid action if the dentist has authorized it and it does not involve diagnosis or treatment decisions, but it is not a substitute for evaluation.
2. Difficulty swallowing with facial swelling and fever is a red flag. What is the appropriate disposition?
Read the worked answer
This presentation suggests a spreading odontogenic infection with possible airway involvement; difficulty swallowing plus fever and swelling is an emergency. The patient should be directed to an emergency department or urgent care capable of airway management immediately, not wait two days for the office to reopen. Dr. Chen should be contacted by phone, and he (not Marcus) should make the referral decision and, if he chooses to prescribe, do so himself after a documented discussion or direct evaluation consistent with his licensure. Marcus's role is to convey the referral and help the patient get to definitive care.
3. If Dr. Chen wants to authorize antibiotic therapy by phone, what considerations govern that decision?
Read the worked answer
Prescribing is the dentist's act, not the assistant's. Dr. Chen must make a clinical judgment based on an adequate history (he cannot rely on Marcus's unlicensed assessment of swelling), document the rationale, and recognize that antibiotics are adjunctive-the source control (incision/drainage or extraction) is definitive and may require urgent referral. He should not direct Marcus to relay a prescription as if Marcus were evaluating the patient. If Dr. Chen cannot adequately assess, the safe course is ED referral rather than a phone prescription that delays definitive care.
