With the exception of nitrous oxide, all other dental sedation methods require that you have a driver present to drive you home after the procedure. This is because the sedation effects will last longer than the procedure itself. Depending on the level of sedation you receive, it may also be advisable to have someone monitor you for the first 24 hours after your procedure. After receiving dental sedation, it is important to take it easy, drink plenty of water, and start out by eating stomach-friendly foods.
