Nitrous Oxide

Nitrous Oxide/Laughing Gas at Evergreen Dental Group in Kirkland, WA

For years, nitrous oxide has provided dental patients with light sedation benefits during their treatment appointments. At Evergreen Dental Group our patients can elect to have nitrous oxide (also known as “laughing gas”) during any procedure. Our ultimate goal is to help you maintain the best comfort level possible, even if it means reducing sensitivity during a preventive cleaning.

Benefits of Laughing Gas

Nitrous oxide is easy to use, safe for all ages, and has very few contraindications. After reviewing your medical history with you, a soft nosepiece is placed over your face to breath through during your appointment. The scented piece mixes pure oxygen with a light level of nitrous gas, providing you with benefits like:


  • A warm, relaxed sensation from head to toe
  • Quick onset and reversal
  • Light sedation that keeps you comfortable yet fully conscious
  • An extremely affordable comfort option
Nitrous Oxide/Laughing gas helps you relax at Evergreen Dental Group in Kirkland, WA

Laughing gas takes just a few minutes to achieve full strength, and is reversed in just 5 minutes of breathing 100% oxygen after your procedure. Our patients can drive themselves home or even return to work if they like!
