Make sure you are escorted home by a responsible party. It is recommended that you stay home for the remainder of the day.
Stay in the presence of a responsible party until you are fully alert again.
Avoid any tiring or laborious activity (including driving) for the rest of the day.
Do not consume a heavy meal right away. If you feel hungry, you are better off with light foods like a piece of toast.
If you are feeling sick and experiencing nausea, lie down. A soft drink can help as well.
Do not consume alcohol or take medications for the remainder of the day, unless otherwise directed by the dentist.
Take further medications as directed by your dentist.
If anything, unusual occurs, call your dentist.
