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.
If your child is nervous about the dentist, I know how tight a parent’s stomach can get as the appointment gets closer. Laughing gas is one of the gentlest ways I know to help anxious patients relax, and I want you to understand exactly what it is before you say yes.
Key takeaways
- Nitrous oxide (laughing gas) is a mild inhalation sedative given through a small nasal mask; you stay awake, responsive and in control.
- It works within minutes, can be adjusted during treatment and wears off quickly once pure oxygen is given at the end.
- It helps patients with dental anxiety, a strong gag reflex, needle fear or longer procedures, following a routine medical assessment.
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.

A patient’s experience
One parent told us her son used to grip the armrests before the chair had even tilted back. With a light mix of nitrous oxide and oxygen he stayed awake and chatty through his treatment, and afterwards he asked if he could have the ‘funny air’ again next time.
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.
