Manage Your Dental Anxiety With Nitrous Oxide

Nitrous oxide is a 100% safe and effective method for managing pain and easing dental anxiety during treatment for both kids and adults. Also known as laughing gas, this colourless odourless gas is used to induce mild sedation that wears off quickly, so you can get back to your day after your appointment.

Contrary to popular belief, nitrous oxide does not put patients to sleep, but rather eases them into a relaxed state. In this state, sensitivity to pain is greatly reduced, as is the gag reflex and extreme anxiety

The benefits of dental sedation

Sedation and sleep dentistry are useful options that help us serve patients from all walks of life with many different challenges to overcome. Some of the benefits of sedation dentistry are as follows:

Overcoming Dental Anxiety

Sometimes the fear and worry can feel worse than the treatment itself. Dental anxiety shouldn’t stand between you and the dental treatment you need. If you have mild or extreme dental anxiety or fear is keeping you from seeking dental treatment, please speak up! We can help.

Make Time Fly By

For long procedures that leave you sitting in the chair with your mouth wide open for a long time, sedation will keep you relaxed and comfortable. Your procedure will be over before you know it. If you require IV sedation, it will feel like an instant has passed.

Tailored for Your Personal Needs

Do you have a sensitive gag reflex? Chronic restlessness or restless leg syndrome? Does local freezing just not work for you? Sedation is really helpful in many different cases, ensuring that treatment is available to everyone.

What Happens During Nitrous Oxide Sedation?


Before moving forward with nitrous oxide treatment, your doctor will discuss your medical history with you to determine if nitrous is a safe option. There are a few reasons why nitrous oxide treatment may not be the best idea for you. Avoid nitrous oxide if the following conditions apply to you:

  • You’re in the first trimester of pregnancy
  • You experience respiratory problems
  • You have a vitamin B-12 deficiency
  • You have a history of substance abuse
  • You suffer from mental illness

Quick and Efficient

Once your doctor has determined that nitrous oxide is right for you, they will begin the treatment. The administration of nitrous is simple; the doctor places the mask snuggly over your nose and mouth and asks you to breathe and relax.

One reason nitrous oxide is such a popular option is how quickly the effects wear off. After treatment, the doctor will administer at least 5 minutes of 100% oxygen to ensure that the nitrous has been exhaled from your system.



Your face may still feel numb if a numbing medication was also used, but the relaxation effects of the nitrous oxide will be gone after the mask is removed. Once you’ve finished your dental treatment, you can safely return to work and eat.


The Cost Of Nitrous Oxide Treatment in London

The cost of nitrous oxide treatment will vary depending on your insurance coverage. The good news is, many insurance plans fully cover this procedure. With most plans, expect to pay anywhere from $0 to $80 and up. Without insurance, you can expect to pay $250 or more.

We suggest contacting your insurance provider to get a quote before visiting our dental clinic.

What Our Patients Have To Say

Zak Jawad

I don't normally write a review but I would like to say that Dr.Weal was extremely patient and careful while extracting my wisdom teeth, especially being a first time client. During the extraction he took his time and made sure I was just as comfortable as if I were getting my teeth cleaned! Dr.Weal even reached out to see how I was doing during my recovery process. I would recommend him and his team to anyone looking for a dentist.
