Dental anxiety can turn even the simplest dental appointment into a source of stress. At McLevin Dental Clinic in Scarborough, Ontario, we understand how fear of the dentist can prevent patients from seeking the care they need. Thats why we offer sedation options designed to make your visit calm and comfortableone of the most commonly used being nitrous oxide, better known as laughing gas.
In this blog, well explain what laughing gas is, how it works, who its suitable for, andmost importantlywhy its considered a safe and effective method of managing dental anxiety.
What Is Laughing Gas?
Laughing gas is the common name for nitrous oxide, a colorless, odorless gas used in dentistry to promote relaxation and reduce anxiety. It is inhaled through a small mask placed over the nose and works quickly to induce a calm, light-headed, or slightly euphoric feelinghence the nickname.
Nitrous oxide is not meant to put you to sleep. Instead, it helps you feel relaxed and comfortable while staying awake and able to respond to instructions during your dental procedure.
How Does Laughing Gas Work?
Laughing gas works by slowing down the bodys reaction time. It interacts with your nervous system to produce a sense of ease, reducing your awareness of fear or discomfort.
The process is simple:
A soft mask is placed over your nose.
You breathe in a mixture of nitrous oxide and oxygen.
Within minutes, you begin to feel more relaxed, and anxious thoughts fade.
Once the procedure is complete, pure oxygen is administered for a few minutes to flush the nitrous oxide from your system.
You return to your normal state almost immediately after the mask is removed.
What Does Laughing Gas Feel Like?
The effects of laughing gas vary slightly from person to person, but most describe it as:
Light-headedness
Tingling in the hands or feet
Warmth or floating sensation
A sense of calm and detachment
Mild euphoria or giggling (in some cases)
These effects typically subside within a few minutes after the gas is turned off.
Is Laughing Gas Safe?
Yes, laughing gas is considered one of the safest and most widely used forms of dental sedation. It has been used in dentistry for over 150 years and is well tolerated by most patients, including children and adults.
At McLevin Dental, we follow strict protocols to ensure your safety:
The gas is carefully administered and monitored by trained professionals.
The amount of nitrous oxide is precisely adjusted for your comfort.
Oxygen is always administered alongside the nitrous to maintain safe breathing levels.
After the procedure, oxygen flushes the gas out of your system completely, with no lingering sedative effects.
Because the effects wear off quickly, most patients can resume normal activities, including driving, shortly after the procedure.
Who Can Benefit from Laughing Gas?
Laughing gas is an excellent choice for patients who experience:
Mild to moderate dental anxiety
Fear of needles or injections
A sensitive gag reflex
Difficulty staying still during treatment
Anxiety about specific procedures like cleanings, fillings, or impressions
Sensory sensitivity to sights, sounds, or smells in the dental office
Its especially popular for children, as it helps them stay calm without the need for deeper sedation.
Who Should Avoid Laughing Gas?
While nitrous oxide is safe for most people, it may not be recommended for individuals who:
Are pregnant in the first trimester
Have chronic respiratory conditions such as COPD
Have a history of severe vitamin B12 deficiency
Cannot tolerate a nasal mask due to congestion or facial differences
Have certain neurological conditions or psychological sensitivities
Before recommending laughing gas, our team performs a full health assessment and discusses your medical history to ensure its appropriate for your specific needs.
Laughing Gas vs. Other Sedation Options
At McLevin Dental, we tailor sedation options to each patient. Laughing gas offers several advantages:
Fast-acting and reversible: Youre back to normal minutes after treatment.
No needles: Sedation is delivered through inhalation, not injection.
Safe for all ages: From children to seniors, nitrous oxide is gentle and versatile.
Customizable: The amount of gas can be easily adjusted during treatment.
For patients with higher levels of anxiety, oral sedation or IV sedation may be more suitable. We will help you choose the best option based on your comfort level and the procedure involved.
