Dental anxiety, also known as odontophobia, is a common fear that can lead to avoidance of dental appointments. However, some people experience such extreme anxiety that they fall asleep during dental procedures.
There are a few reasons why someone might fall asleep during a dental appointment. One possibility is that the person is simply exhausted. Dental appointments can be stressful, and the person may be feeling overwhelmed. Another possibility is that the person is taking medication that makes them drowsy. Finally, some people may have a condition called syncope, which can cause them to faint or lose consciousness during stressful situations.
