Just like other forms of sedation dentistry, IV sedation will relax you and make you completely comfortable. IV sedation also eliminates your anxiety and pain. If you have a bad gag reflex or difficulty sitting in a dental chair for long periods, IV sedation will help you with that, as well. You’ll be so relaxed that you may be unaware of the sights, smells, and sounds of the dental office, but still able to respond to verbal cues from the dentist. Patients remember little to nothing of their appointment by the next day.IV sedation gives your dentist optimum control of the amount of medication administered – your level of sedation can be increased or decreased quickly and comfortably.
