Nitrous oxide is the main form of sedation dentistry we offer. Also called laughing gas, nitrous oxide is a gas that produces a relaxed, euphoric feeling. You will inhale the nitrous oxide, which is mixed with a high percentage of oxygen, through a nose mask during your dental treatment. You will remain awake and able to respond to any questions or instructions from our dentist, but you will feel more comfortable and at ease. Nitrous oxide is very safe, and the effects will wear off within just a few minutes after we end the gas flow.
