Nitrous Oxide or Laughing Gas

  • Nitrous oxide, or “laughing gas,” is a safe and effective inhaled sedative used in dentistry to reduce anxiety and pain during procedures. It is administered through a nasal mask and allows the patient to remain conscious, but in a state of calm euphoria, and is a quick-acting and fast-recovering sedation method. The process involves the patient breathing a mixture of nitrous oxide and oxygen, with the concentration being adjusted throughout the procedure.  

How it Works

  • Conscious Sedation: Nitrous oxide keeps the patient conscious, so they can respond to the dentist’s instructions, unlike general anesthesia where the patient is asleep.
  • Relaxation and Anxiety Relief: It slows down the nervous system, inducing a sense of calm, euphoria, and detachment, which helps manage dental anxiety.
  • Pain Reduction: It raises the pain reaction threshold and can decrease pain, especially when combined with local anesthesia.
  • Increased Cooperation: It can help reduce movement, improve cooperation, and increase tolerance for longer appointments.
  • Quick Onset and Recovery: The effects begin quickly, and once the gas is turned off, the patient recovers within minutes after being given pure oxygen for a few minutes to clear the system.

Who is it For?

  • Anxious Patients: It is ideal for both children and adults who experience stress or anxiety about dental treatment.
  • Patients with a Strong Gag Reflex: It can be effective in controlling a hyperactive gag reflex.
  • Special Needs Patients: It is helpful for patients with intellectual disabilities or other special healthcare needs that make it hard to sit still.
  • Patients with Low Pain Tolerance: It is useful for those who are more sensitive to pain during procedures.

Contraindications

  • Individuals in their first trimester of pregnancy.
  • People with respiratory illnesses or Chronic Obstructive Pulmonary Disease (COPD).
  • Those with a B-12 deficiency.

After the Procedure

  • After the dentist removes the nasal mask, the patient receives 100% oxygen for about five minutes to flush the gas from their system.
  • Recovery is very quick, typically within 15 to 30 minutes.
  • The patient can usually drive and go about their day after the procedure.
