Nitrous Oxide

2013315113446418_imageNitrous oxide, or NO2, is a colorless gas with a slightly sweet taste and odor that is used for its calming effect. Mixed with oxygen, nitrous oxide is inhaled through a soft nose piece or mask attached to hoses to the nitrous oxide and oxygen tanks. Dentists typically use a mixture that is 25- to 40% nitrous oxide. The gas begins to work in three to five minutes and can help you relax, ease your fear and make you feel more comfortable, especially during lengthy dental procedures. In most people, nitrous oxide produces a sense of security, a feeling of warmth and a pleasant, floating sensation. You may also feel some or all of the following:

  • Tingling in your hands and feet
  • A feeling of numbness in your tongue, thighs, hands or feet
  • A feeling of heaviness or lightness
  • Changes in the way you hear sounds
  • Sleepiness
  • Euphoria
  • Nausea
