Need just a little extra help taking the edge off before your cleaning or filling? Nitrous oxide—better known as laughing gas—helps kids and adults feel warm, calm, and relaxed within minutes, and because it wears off right after your appointment, you can even drive yourself home.
What is nitrous oxide (laughing gas)?
Nitrous oxide is a sweet-smelling, colorless blend of nitrous oxide and pure medical oxygen. It is administered through a small, soft silicone nose cushion that rests gently over your nose while you recline comfortably in the dental chair.
As you breathe normally through your nose, the gas enters your system within 2 to 3 minutes, calming the central nervous system, naturally elevating your pain threshold, and inducing a warm, peaceful wave of physical relaxation and mental calm. Unlike deeper sedation methods, you remain 100% awake and able to communicate with our team—and once your procedure is complete, a 3-to-5-minute flush of pure oxygen clears the gas completely from your body so you can safely drive yourself home.
Works in 2–3 minutes
No pills to take ahead of time and no needles required. Relaxation begins within a few gentle breaths and can be adjusted moment by moment during your visit.
Awake, calm & in control
You breathe naturally on your own, remain fully conscious, and can easily answer questions or let your dentist know how you are feeling at any time.
Drive yourself home
After 3 to 5 minutes of breathing 100% pure oxygen, the sedative effects vanish completely with zero grogginess—no adult escort or recovery day needed.
We believe that dental nervousness should never stand between you and a healthy, confident smile. Nitrous oxide inhalation sedation can be added affordably to virtually any appointment at our Everett dental office—from routine teeth cleanings and pediatric checkups to fillings, root canals, crowns, and tooth extractions.
To make your entire treatment plan as manageable as possible, we accept most major PPO dental insurances and offer convenient monthly financing through CareCredit®. Our friendly front-office team will gladly review your coverage and provide transparent cost estimates before treatment begins.

Who benefits most from laughing gas sedation?
Because nitrous oxide is ultra-gentle, non-allergenic, and rapidly reversible, our dentists frequently recommend it for patients who experience:
- Mild-to-Moderate Dental Anxiety: Melts away physical tension and racing thoughts triggered by dental sights, sounds, or vibrations.
- Nervous Children & Teens: Helps young patients feel safe, calm, and cooperative during pediatric dental visits without lingering drowsiness.
- Sensitive Gag Reflex: Relaxes throat and oral reflexes so X-rays, digital scans, and back-molar treatments feel effortless.
- Fear of Needles or Numbing: Naturally dulls pain receptors so local anesthetic numbing is barely noticeable.
- Busy Schedules Requiring Zero Downtime: Ideal for adults who cannot take a full day off work or arrange a designated driver.
What happens during a laughing gas appointment?
From the moment you settle into the chair until you walk out the door, nitrous oxide sedation is designed to be effortless, predictable, and tailored to your comfort:
You recline comfortably while we place a lightweight, breathable nose hood gently over your nose—leaving your mouth completely free.
We begin with a refreshing flow of pure oxygen and gradually introduce nitrous oxide, fine-tuning the exact percentage to match your comfort needs.
As you breathe normally through your nose, a warm, light tingling sensation and a calm sense of detachment wash over you in just minutes.
Once you are completely relaxed, our dentist numbs the treatment area gently (if needed) and completes your care while monitoring you continuously.
When your procedure finishes, you breathe 100% pure oxygen for 3 to 5 minutes—clearing all nitrous oxide from your lungs so you leave feeling clear-headed and refreshed.

Frequently asked questions
Answers to nitrous oxide (laughing gas) questions
- Severe Nasal Congestion: Because you must breathe through your nose for the gas to work, a heavy cold, sinus infection, or blocked nasal passage will prevent effective inhalation.
- Pregnancy: Elective nitrous oxide sedation is generally avoided during pregnancy, particularly during the first trimester.
- Certain Respiratory or Medical Conditions: Patients with severe chronic obstructive pulmonary disease (COPD), recent inner-ear or retinal surgery, or vitamin B12 / MTHFR deficiency should consult with our dentists during their medical history review.
