Final answer:
Advertising by dentists is subject to laws and regulations. Unlawful advertising refers to violations of these laws. Unprofessional advertising goes against ethical standards of the dental profession.
Step-by-step explanation:
Advertising by dentists is subject to certain laws and regulations. Unlawful advertising refers to any advertising that violates these laws. This could include false or misleading statements, failure to disclose information, or making claims that cannot be substantiated.
Unprofessional advertising, on the other hand, may not necessarily be illegal, but it goes against the ethical standards of the dental profession. This can include aggressive or deceptive marketing tactics that prioritize profit over the well-being of patients.
It's important for dentists to familiarize themselves with the laws and professional guidelines related to advertising to ensure that their advertisements are both legal and ethical.
