For how long must advertised fees be available at or below the advertised amount?

• A. For 60 days after the final advertisement.
• B. For at least 90 days following the final advertisement.
• C. For 120 days after the final advertisement.
• D. For 30 days after the final advertisement.

Answer: (B)

The question tests advertising rules for professional fees and how long a price claim must remain available. When a dentist advertises a fee, the rule requires that the advertised amount or a price at or below it must be kept available for at least 90 days after the final advertisement in that campaign. This ensures the price is reliable and verifiable for potential patients and helps prevent bait-and-switch practices where a price is promoted briefly and then raised or withdrawn.

If the duration were shorter, such as 60 or 30 days, a patient might not have a real chance to act on or verify the advertised price. A longer period, like 120 days, isn’t the mandated minimum, though it could be acceptable if explicitly stated by the governing rules. The 90-day timeframe strikes the right balance by giving a stable window for consumers to review pricing while not unnecessarily constraining advertising.
