Dental Inhalation sedation uses Nitrous Oxide which is inhaled through a nose piece that is placed on the nose. Nitrous Oxide has a long history of safe use in dentistry.
It suppresses the central nervous system to allow the dentist to perform some dental treatments without minimal physiological and psychological stress to the patient.
Communication is maintained through out the procedure. The patient is never 'knocked out' completely.
It carries a safety margin to ensure that the patient doesn't lose consciousness nor lose any protective reflexes. Complications are rare.
There are a few contraindications:
- medical conditions preventin the inhalation of the nitrous oxide, e.g the common cold, tonsilitis, severe COPD or nasal blockages.
- neuromuscular diseases affecting the respiratory system; e.g multiple sclerosis and myasthenia gravis.
- pregnant women.
- medical or behavioural conditions that limit a patient's ability to understand the procedure.
- Claustrophobia or "fear of the mask'.
There is no "hangover' effect with inhalation sedation. The Nitrous oxide is eliminated from the body in 3-5 minutes. after the nitrous gas has been turned off. Oxygen is given for 5-10 minutes after the treatment.
Recovery is extremely quick and adult patients can safely drive home and with out an escort.
