Patients can revoke their consent for denture delivery even after starting the procedure. Informed consent is an ongoing process that allows patients to make informed decisions about their care, and they can change their minds at any time. If patients decide to revoke their consent for denture delivery, they should inform their dentist as soon as possible. The dentist will then work with the patient to understand the reasons behind their decision and discuss any alternative options that may be available. It is important to note that revoking consent may have consequences, such as the need to reschedule the appointment or potentially delay treatment. Patients should discuss their concerns with their dentist to ensure they fully understand the implications of revoking their consent.
