Dental Sedation in Mississauga, ON

If dental visits make you feel nervous or if your child needs extra comfort during treatment sedation dentistry can make all the difference. At Trio Dentistry in Mississauga, we offer safe and effective nitrous oxide sedation to help patients feel relaxed, in control, and comfortable throughout their appointment.

Whether you’re struggling with dental anxiety, have a sensitive gag reflex, or are undergoing a longer procedure, our gentle sedation option helps make dental care easier for everyone.

What Is Dental Sedation?

Dental sedation uses medication to help patients relax during dental procedures. At Trio Dentistry, we use nitrous oxide, commonly known as laughing gas, which is a mild and fast-acting sedative inhaled through a small nosepiece.

Nitrous oxide helps reduce anxiety and discomfort without putting you to sleep. You’ll remain awake, able to respond, and recover quickly after treatment.

Who Can Benefit from Sedation Dentistry?

Sedation is helpful for a variety of patients, including:

  • Anxious patients who have dental fear or past traumatic experiences
  • Children and teens who feel overwhelmed in the dental chair
  • Patients with special needs who require extra care
  • Individuals with a strong gag reflex
  • Those undergoing lengthy or multiple procedures in one visit


We personalize sedation care to meet each patient’s medical history, age, and comfort level.

Sedation Option Offered at Trio Dentistry

Nitrous Oxide (Laughing Gas)

Nitrous oxide is a light, colorless gas that takes effect within minutes and helps patients feel calm, detached from anxiety, and more accepting of treatment.

Benefits include:

  • Fast onset and offset (you can return to normal activities after the appointment)
  • Safe for both children and adults
  • Adjustable levels during treatment
  • Does not require fasting before the appointment


This makes it ideal for pediatric patients, anxious adults, and anyone needing a stress-free visit.

Who Administers Sedation?

Sedation at our clinic is provided by our general dentist trained in sedation techniques. You can feel confident knowing that your safety and comfort are in expert hands.

Our team follows strict protocols and undergoes continued training to ensure that sedation is delivered with precision and care.

Safety Is Our Priority

At Trio Dentistry, we take sedation seriously and follow thorough protocols to keep you or your child safe:

  • Pre-screening and medical history review to assess sedation suitability
  • Continuous monitoring of breathing, heart rate, and oxygen levels during treatment
  • Emergency protocols in place and ready for rare complications
  • Post-treatment instructions and follow-up to ensure a smooth recovery


Your comfort matters, but your safety always comes first.

What to Expect with Nitrous Oxide

Here’s how your sedation appointment will go:

  1. Preparation: We place a small mask over your nose to deliver nitrous oxide.
  2. Sedation begins: Within minutes, you’ll feel lighter, calmer, and more relaxed.
  3. Treatment proceeds: Dental work begins while we monitor and adjust sedation as needed.
  4. End of procedure: Nitrous is turned off, and you breathe oxygen to clear the effects.
  5. Recovery: You’ll feel normal again within minutes and can typically drive yourself home.


We’ll provide detailed instructions and answer any questions before the appointment begins.

Sedation Dentistry for Children

We take extra care when working with children. For young or anxious kids, laughing gas provides a gentle introduction to dental treatment. It helps reduce fear, increase cooperation, and prevent the development of long-term dental phobia.

We explain everything to kids using our Tell-Show-Do technique and allow them to feel in control. Parents are welcome to stay in the room and comfort their child during care.

Does Insurance Cover Sedation?

In many cases, dental insurance does not fully cover nitrous oxide, but it’s often a modest, affordable add-on. We:

  • Provide transparent pricing upfront
  • Offer direct insurance billing
  • Help assess whether sedation is covered for children or special circumstances


Our team will make sure you know all your options.
