Nitrous (Laughing) Gas

The most commonly employed technique used by our Van Nuys dentistry in conscious sedation dentistry is inhalation sedation with nitrous oxide and oxygen (N20-02) or "laughing gas". It is estimated that approximately 35% of U.S. dentists use this technique to relieve pain and dental anxiety.

The goal sought when laughing gas is used is to eliminate dental anxiety, making the patient more comfortable while the sedation dentist is able to more effectively complete the planned dental care procedure while the patient is sedated.

A small rubber inhaler will be placed over the patient's nose and adjusted so that the patient is comfortable. At this time, the patient will be breathing 100% oxygen.  The signs and symptoms that most patients experience when receiving laughing gas include an initial feeling of lightheadedness, which gradually leads to an all-over feeling of warmth. Many persons mention a comfortable "vibrating" or "humming" sensation. It is common to feel one's fingertips and hands become "numb."  This same sensation may develop in the mouth.

At the conclusion of the sedation dentistry treatment, the patient will once again receive 100% oxygen (for a minimum of one to five minutes). At the end of this time, the person should feel absolutely back to normal.

Laughing gas inhalation sedation is highly effective in the management of mild to moderate levels of dental anxiety. It also is an excellent technique in persons who are extreme gaggers; laughing gas usually eliminates or minimizes gagging in most patients.
