Is it ethical for a dentist to refuse a patent because the patent does not want to take x-rays during regular teeth cleaning?

Yes, it can be considered ethical for a dentist to refuse treatment if a patient declines necessary diagnostic procedures like x-rays, especially if these are essential for ensuring the patient's oral health and safety. Dentists have a professional obligation to provide care based on best practices, which often include taking x-rays to detect underlying issues. Refusing treatment in such cases can help protect both the patient's well-being and the dentist's professional integrity. However, the dentist should communicate clearly with the patient about the reasons for this requirement.
