Nitrous oxide sedation for dental anxiety
At Msmiline Cosmetic Dentistry of Pierrefonds, Quebec, Dr. Ramin Mirmooji and his dental associates understand that patients of all ages may be anxious about their upcoming dental appointment. Patients who are honest about their anxiety may find that solutions such as nitrous oxide sedation can ease their worries and help them relax during treatments.
What is nitrous oxide sedation?

Led by Dr. Mirmooji, the team at Msmiline Cosmetic Dentistry may recommend nitrous oxide sedation for patients with dental anxiety. This particular type of sedation is a form of inhalation sedation that uses nitrous oxide, also known as “laughing gas,” to relax patients during dental procedures. Nitrous oxide is one of the safest forms of sedation because it leaves the body quickly, allowing our patients to return to routine activities and drive right after their procedure. During treatment, patients must wear a mask over the nasal area that allows them to breathe in nitrous oxide-an odourless and colourless gas. The effect generally starts within two minutes and can last up to 20 minutes after the mask has been removed if oxygen is not administered to clear the airways of the gas.
When might I consider nitrous oxide?
Many of our patients who ask for nitrous oxide sedation services during their treatment know how it can ease the anxiety of having certain dental procedures performed. In addition to helping those with mild anxiety, nitrous oxide can also be used for those who have difficulty getting numb from local anesthesia or for more lengthy procedures when more comfort would be desired. After receiving nitrous oxide sedation, oxygen will be administered afterward so patients can return to their daily activities-including driving after their appointment.

Nitrous Oxide Sedation FAQs
What is nitrous oxide sedation?
Also referred to as laughing gas, nitrous oxide sedation is a mild sedative option offered to Dr. Mirmooji’s patients who may need some assistance remaining relaxed during dental treatment or procedure. Nitrous oxide is applied using a mask placed over your nose and is mild enough to stay comfortable yet fully conscious. This sedation method is safe, fast-acting, and wears off quickly, making it ideal for reducing anxiety and discomfort during dental visits. Nitrous oxide is a gentle, non-invasive way to help you feel at ease while receiving care.
Is nitrous oxide sedation safe?
Nitrous oxide is very safe when used by a trained dental professional. It has been used in dentistry for many years with minimal side effects. The gas is carefully monitored to ensure you receive the right amount, and oxygen is continually supplied to maintain your safety. After the procedure, the effects of nitrous oxide wear off quickly, allowing you to resume normal activities almost immediately. It’s one of the safest sedation options available in dental care.
How does nitrous oxide sedation make me feel?
Nitrous oxide creates a feeling of deep relaxation and mild euphoria. Many patients feel calm, comfortable, and detached from the procedure, even though they remain awake and aware. You may also experience a slight tingling sensation or warmth. Despite the relaxed state, you can communicate with Dr. Mirmooji and follow instructions during the procedure. This allows you to feel at ease without compromising your ability to cooperate during treatment.
How long does nitrous oxide sedation last?
The effects of nitrous oxide sedation are very short-lived. Once the gas is stopped, the sedative effects wear off quickly, typically within a few minutes. You may feel back to normal almost immediately, making it a convenient option for patients who need to drive or return to their regular activities after their appointment. This quick recovery makes nitrous oxide ideal for patients with busy schedules or those seeking minimal downtime.
Who can benefit from nitrous oxide sedation?
Nitrous oxide is an excellent option for patients with mild to moderate anxiety about dental procedures. It’s also helpful for individuals with a sensitive gag reflex, those undergoing lengthy procedures, or anyone who experiences discomfort during dental visits. Dr. Mirmooji will assess your needs and determine if nitrous oxide sedation is a good fit for you. It’s suitable for adults and children, ensuring a comfortable experience for patients of all ages.
Are there any side effects of nitrous oxide sedation?
Most patients experience no lasting side effects after nitrous oxide sedation. However, some may experience mild nausea or dizziness, which resolves quickly after breathing oxygen. Rarely, patients might feel lightheaded or have a headache. Dr. Mirmooji will ensure your comfort throughout the process and address any concerns. You can easily manage any persistent side affects you may have.
Do I need someone to drive me home after using nitrous oxide sedation?
No, one of the major advantages of nitrous oxide sedation is that it wears off quickly, and most patients can resume normal activities immediately after their appointment. You will be alert and able to drive yourself home. However, if you feel any lingering effects or feel particularly tired, it’s best to have someone with you just in case. Most patients feel fully recovered within minutes of the procedure.
