What is Nitrous Oxide (Laughing Gas) Sedation?
You inhale a controlled mix of nitrous oxide and oxygen through a small comfortable nose mask. Within minutes you feel calm and relaxed. When the mask comes off, the effect wears off quickly, and you can drive yourself home.

How nitrous oxide actually works
You breathe a controlled mix of nitrous oxide and oxygen through a small nose mask. Within two to three minutes you feel a warm, calm, slightly floaty sensation. You are fully awake the whole time. You can talk to us, you remember the visit, and you can drive yourself home minutes after we switch you back to pure oxygen at the end. Nitrous is the lightest, safest sedation option in dentistry, used in millions of appointments every year for both adults and children.
Why we offer it as a default option
Roughly one in three of our patients tells us at some point that they are nervous about the dentist, and many more under-report. Anxiety is the number one reason people delay care and let small problems become large ones. Nitrous removes the barrier without committing you to IV sedation or general anaesthesia. We offer it for routine cleanings, fillings, root canals, extractions, and especially for kids who are getting comfortable with the chair. If you are anxious, tell our receptionist when you book and we will plan the time.
Safety and who should not have nitrous
Nitrous oxide has been studied for over a century. Its safety profile in dental settings is well established. Patients who should not have it: anyone in the first trimester of pregnancy, patients with severe COPD or recent middle-ear surgery, patients on bleomycin chemotherapy, and patients with a vitamin B12 deficiency. We screen for these on your medical history before we use it. If nitrous is contraindicated for you, we use other comfort tools: longer appointments, headphones, topical anaesthetic before the freezing needle, and frequent check-ins.
Nitrous for children, our approach
For children, nitrous is often the difference between a successful first restoration and a long history of avoidance. We start with the lowest effective concentration, talk through what they are feeling, and use it for short appointments only. Most kids tolerate it well and many describe it as a tingly, warm feeling. Parents stay in the room. If a child cannot or will not accept nitrous after a calm introduction, we step back and rebook rather than push. Comfort builds trust and trust pays off across a lifetime of dental visits.
Combining nitrous with local anaesthetic
Nitrous reduces anxiety and softens the gag reflex. It does not numb teeth on its own. For any procedure that needs anaesthesia we still use a local injection, usually with a topical gel first so the needle is barely noticeable. The combination of topical, local anaesthetic, and a low dose of nitrous handles the vast majority of dental procedures comfortably. For longer surgical cases, deeper sedation (oral conscious sedation or IV sedation by a visiting anaesthetist) is occasionally the right choice, and we coordinate that with our surgical referral network.
Cost and insurance
Nitrous oxide sedation is typically $75 to $150 per appointment depending on the length of use. Many private dental insurance plans cover it for procedures where sedation is clinically justified, particularly oral surgery and longer treatments. CDCP covers nitrous when needed for specific procedures. We confirm coverage before billing.
