Dental anxiety is far more common than most people admit. Fear of injections, dental sounds, gag reflex, or past experiences can make even simple dental procedures stressful.
Nitrous oxide sedation commonly known as laughing gas offers a gentle, safe, and effective way to help patients feel relaxed and comfortable during dental treatment, without putting them to sleep.
At Tricity Smiles Dentistry, nitrous oxide sedation is used as part of a patient-first, comfort-focused approach, helping patients receive dental care calmly and confidently.
What Is Nitrous Oxide Sedation?
Nitrous oxide is a mild inhalation sedative mixed with oxygen and administered through a small nasal mask. It works quickly to reduce anxiety and discomfort while keeping the patient awake, responsive, and in control throughout the procedure.
Key characteristics:
Rapid onset (within minutes)
Adjustable levels during treatment
Effects wear off quickly once stopped
No needles involved
Patients often describe a feeling of calm, lightness, or mild euphoria.
Who Can Benefit From Nitrous Oxide Sedation?
Nitrous oxide sedation may be recommended for patients who:
Experience dental anxiety or fear
Have a strong gag reflex
Feel nervous about injections or dental instruments
Need longer or multiple dental procedures
Find it difficult to stay relaxed during treatment
It is one of the most widely used and safest forms of dental sedation.
Is Nitrous Oxide Sedation Safe?
Yes. Nitrous oxide has been used safely in dentistry for decades and has an excellent safety record when administered by trained dental professionals.
Why it’s considered safe:
Non-invasive
No loss of consciousness
Easily adjustable and reversible
Continuous oxygen delivery and monitoring
Minimal & Temporary Side Effects
Nitrous oxide is generally very well tolerated. When side effects occur, they are usually mild and short-lived:
Slight dizziness or light-headedness
Mild nausea (uncommon)
Tingling in hands or feet
Temporary warmth or heaviness
These effects typically resolve within minutes after breathing pure oxygen at the end of the procedure.
What Does Nitrous Oxide Feel Like?
Most patients report:
Deep relaxation
Reduced awareness of time
Less sensitivity to sounds and sensations
Ability to communicate normally
You remain fully conscious and can respond to instructions at all times.
