Conscious sedation is a mix of nitrous oxide (N2O) and oxygen (O) that is administered through a nasal mask with personalised concentrations according to need. The analgesic and sedative effect is already felt after a few breaths with a relaxing sensation. The patient however stays completely conscious and vigilant during the treatment. At the end of the treatment, pure oxygen is administered for 5 minutes and this allows the patient to leave the dental office alone and able to drive.

Conscious sedation is suitable for adults as well as babies. It allows any type of treatment to be carried out: fillings, root canal treatments, surgery, and implantology. Even annoying retching, for example when taking impressions, are practically eliminated with conscious sedation.

Conscious sedation is an extremely safe method in that the mix breathed in is:

  • inactive
  • non-toxic
  • there are no nitrous allergies
  • it is not metabolised by the body
  • it does not alter the patient’s protective reflexes such as swallowing and coughing which are still present.


    Conscious sedation is a technique that has been used for more than forty years in the United States and North Europe where it has developed a notable success thanks to its simplicity and versatility.

    The method is not, however, recommended for patients that have difficulty breathing through the nose, for babies less than 3 years old and in some disabled people who cannot voluntarily breathe through the nose. Other side effects are: vitrectomy in the first two months post operation, in the case of rebuilding the eardrum, and in patients that take drugs.
