If a patient is worried by the sights, sounds or sensations of dental treatment, they may respond more positively with the use of nitrous oxide / oxygen, also called happy gas. Perhaps the safest analgesic in dentistry, nitrous oxide/oxygen can reduce anxiety and gagging in patients and make long appointments easier.
The patient remains fully conscious during treatment. Recovery after treatment is rapid and complete. Nitrous oxide is not effective for patients who are congested or will not breathe through their nose.
