Most of dental interventions can be performed without pain due to modern anesthetics and techniques. However there are still some patients who become anxious when they have to sit into the dental chair. Because of a bad experiment or because of some rumors fear of pain can be so serious that anesthesia of the affected area is not enough, there is need for other procedures.
The idea of this method is that during the process the patient inhales a mixture of dinitrogen oxide and oxygen through a mask placed on their nose and this leads to a pleasant, numb feeling. However the patient knows and feels what happens and they can communicate with the dentist, pain does not bother them. They think that the intervention is pleasant and short, they hardly remember anything after the treatment. The process in itself is not enough for performing the whole surgical treatment but the patient is not afraid anymore of the needle and they won’t have negative memories about the surgery. The effect the of gases inhaled disappears totally after 5 minutes of oxygen inhalation and the patient becomes aware.
