The question of whether dentists can rip off patients is a complex one. There are many factors to consider, including the individual dentist's ethics, the patient's financial situation, and the specific dental services being provided.
On the one hand, there are certainly some dentists who have been known to engage in unethical or fraudulent practices. These dentists may charge excessive fees for their services, perform unnecessary procedures, or use substandard materials. In some cases, they may even commit insurance fraud.
