Why There Are Different Levels

Sedation is not a single setting. The American Dental Association describes sedation and general anesthesia as a continuum, running from minimal sedation to general anesthesia. Its guidelines state that, at every level, the dentist must have the training, skills, medications, and equipment to provide care safely. The right depth depends on your anxiety, your health, and how long and complex your treatment will be.

Level 1: Nitrous Oxide ("Laughing Gas")

You breathe nitrous oxide through a small mask over your nose, and you stay awake while feeling relaxed. The Cleveland Clinic says you typically feel calm within three to five minutes, your dentist adjusts the dose throughout, and pure oxygen at the end flushes it out, so you are able to drive afterward. It suits mild to moderate nervousness.

Level 2: Oral Sedation

Oral sedation is a prescription medication taken about an hour before your procedure. It can leave you very tired, and you may even fall asleep, though your dentist can wake you when needed. Because the effects linger, arrange for someone to take you home.

Level 3: IV Sedation

The Cleveland Clinic calls IV sedation the deepest form of conscious sedation available in a dental office, and it is best for severe anxiety or long procedures. Medication goes directly into your bloodstream through an IV line, your heart rate and blood pressure are monitored, and the dose is adjusted as needed. 

You may fall asleep and remember nothing afterward, and sedation may reduce the number of appointments you need. IV sedation is typically for teens and adults, and your medical history is reviewed first.

Level 4: General Anesthesia

With general anesthesia, you are completely unconscious and have no memory of the treatment. The Cleveland Clinic notes that it may be arranged for a young child or someone with severe dental anxiety and that providers must have advanced training. 

For children and teens who cannot complete treatment awake, learn more about general anesthesia dentistry and pediatric sedation.

Frequently Asked Questions

Will I feel pain under sedation?

Dentists typically use local anesthetic and sedation to numb your teeth and gums once you feel relaxed.

Do I need a ride home after sedation?

Yes, for oral sedation, IV sedation, and general anesthesia. You should not drive for 24 hours after oral or IV sedation. Nitrous oxide usually does not require one.

Is sedation dentistry safe?

It is safe when provided by properly trained providers who review your health first, so ask about their training and monitoring.
