The White Patch and the Six-Month Wait
Hygienist Carlos is seeing Mr. B, age 58, a 30-pack-year smoker, for periodontal maintenance. Mr. B mentions a painless white patch on the left lateral tongue that has been present for 6 weeks and has not healed. Carlos documents a 1.5 cm leukoplakia with induration. The dentist looks briefly and says, “We'll watch it and recheck in six months; don't scare him.” The practice has no oral pathology referral protocol. Mr. B has no primary care provider and asks Carlos, “Should I be worried?” Carlos knows that persistent leukoplakia in a smoker warrants prompt evaluation and that delay can affect outcomes. He is due to finish the appointment in 10 minutes.
1. What are Carlos's professional and legal obligations regarding referral of this lesion?
Read the worked answer
Carlos cannot diagnose cancer, but he must recognize an abnormal finding and act on it. A persistent, indurated white patch on the lateral tongue in a 30-pack-year smoker is a red flag that warrants prompt evaluation by an oral and maxillofacial surgeon or oral medicine specialist, not a six-month watch. Carlos's scope includes exposing and documenting abnormalities and reporting them to the dentist; professional ethics require him to advocate for the patient's safety rather than simply follow a convenience-based delay.
He should tell Mr. B that the lesion needs prompt evaluation and explain that this is not a diagnosis of cancer but a reason to have a specialist look at it. He should document the size, location, duration, induration, tobacco history, and the fact that the dentist was informed. He should not ignore the dentist's instruction, but he also should not mislead the patient. The standard is prompt referral, not reassurance that everything is fine.
2. How should Carlos respond to the dentist's instruction and document the encounter?

Carlos should respectfully tell the dentist that he is concerned about the persistent indurated lesion and ask the dentist to examine it again and document a plan. He should request that a referral be made or that the dentist document the decision to wait and the clinical rationale. If the dentist refuses, Carlos should follow any escalation policy, such as involving the office manager or another dentist, and should give Mr. B the referral information directly. He should not say, “The dentist said it's nothing.”
The record should include a clear description of the lesion, the patient's tobacco history, the duration, the fact that the dentist was notified, the referral recommendation, and the patient's response. Carlos should note that Mr. B has no primary care provider and may need help finding a specialist. Documentation should be factual and timely, not altered later.
3. What should Carlos do if the dentist refuses referral and tells him not to mention the lesion to Mr. B?
Read the worked answer
Carlos should not comply with an instruction to conceal a significant clinical finding. That would mislead the patient and could expose both Carlos and the dentist to disciplinary and civil risk. He should tell the dentist he cannot agree to withhold the information, document the instruction and his objection, and give Mr. B the referral recommendation in a factual, non-alarming way. He can say, “I saw an area that has been there for six weeks and should be looked at by a specialist; I am not diagnosing it, but it should not wait six months.”
If the dentist continues to block referral, Carlos should escalate within the practice and consider contacting the Georgia Board of Dentistry for guidance. He should ensure Mr. B leaves with written referral information and a follow-up plan. The patient's safety and the duty not to mislead take priority over the dentist's instruction.
