What should dental assistants do if a patient shows signs of over-sedation?

When a patient exhibits signs of over-sedation, the appropriate response is to immediately call for additional medical assistance. This is critical because over-sedation can lead to serious complications, including respiratory depression, loss of protective reflexes, or even loss of consciousness. By seeking additional medical help, dental assistants can ensure that the patient receives the necessary care from qualified personnel who are trained to handle such emergencies.

In contrast, administering more sedative would be counterproductive and potentially dangerous, exacerbating the situation. Continuing with the procedure disregards the patient's safety and well-being, which is not acceptable. Taking no action until the procedure is completed could lead to worsening symptoms and increased risk to the patient’s health.

Thus, the most responsible and safe action in the event of over-sedation is to alert medical professionals who can intervene appropriately.
