Nitrous Oxide

Using Nitrous Oxide

The reason for using nitrous oxide (“laughing gas”) is for its calming effect. Since it doesn’t numb the teeth, anesthetic is often still necessary. Nitrous oxide simply relaxes you.

You will breathe nitrous oxide in through a small mask that covers your nose. It takes just a few minutes for you to notice the effects. People most often describe the feeling as being relaxed, unconcerned, slightly numb all over, and disconnected from what’s happening around them.

Your dentist can adjust the dosage of the nitrous oxide gas to fit your needs. You can also control its effects by your breathing. The more deeply you breathe through your nose, the more you’ll feel its effects. There are no long-lasting effects of nitrous oxide; you can safely drive after a dental appointment.

Your dentist won’t use nitrous oxide if:

  • You’re pregnant
  • You have an inner ear infection
  • You have asthma

Let the staff know if you’d like to try nitrous oxide to feel more relaxed during your dental appointment.
