Docs can you explain, is it true you shouldn't eat 24 hours before visiting the dentist?

To the contrary: A high protein diet will help your body repair after dental procedures. The only caveat to this is if you are to have impressions taken and you have an exaggerated gag reflex. In that case schedule your appointment for early in the am and hold off eating breakfast until after your appointment.

General anesthesia: That's usually true if your are seeing oral surgeon for impacted wisdom teeth extraction and want or need to be under general anesthesia.

False: Only if you are having general anesthesia or IV sedation, you may not have anything to eat or drink for a minimum of 6-8 hours. You can eat right before you go to the dentist, but it is important that you floss regularly and immediately after you finish eating.
