Feeling nervous before a dental visit is more common than you might think. In fact, dental anxiety affects millions of Canadians every year. If you’ve been putting off your dental care because of worry or fear, sedation dentistry could be the solution you need. Whether you’re looking for a dentist in Peterborough or have already found a dental home you trust, understanding your sedation options can help you feel more at ease before you even sit down in the chair.
Two of the most common options available today are nitrous oxide and IV sedation dentistry. Both are safe and effective, but they work differently and suit different needs. Let’s break it down so you can make an informed choice.
What Is Nitrous Oxide?
Nitrous oxide, often called laughing gas, has been used in dentistry for well over a century. It’s a colourless, odourless gas that you breathe in through a small mask placed over your nose. Within a few minutes, you’ll start to feel calm, relaxed, and a little floaty.
You remain fully awake and can respond to your dentist at all times. That’s what makes this option so popular for routine appointments like cleanings, fillings, and minor procedures.
Benefits of Nitrous Oxide
- Works quickly — effects start within minutes
- Wears off fast — you can usually drive yourself home
- Easy to control the dosage during treatment
- Safe for children and adults
- No needles involved
What Is IV Sedation Dentistry?
IV sedation dentistry involves delivering sedative medication directly into a vein, usually in your arm or hand. It takes effect almost immediately and produces a deeper level of relaxation than laughing gas. Most patients have little to no memory of the procedure afterwards.
You’ll still be able to breathe on your own, and a trained dental professional will monitor your vital signs throughout. This type of sedation is often used for longer or more complex procedures, or for patients who have significant anxiety that doesn’t respond well to lighter options.
Benefits of IV Sedation
- Deeply relaxing — many patients feel as though they slept through the procedure
- Ideal for complex or lengthy dental treatments
- Can be adjusted throughout the appointment
- Great option for patients with a strong gag reflex
- Helpful for those with very high dental anxiety

Which Sedation Option Is Better for Dental Anxiety?
Choosing which sedation option is better for dental anxiety really depends on how you feel about dental visits and what kind of treatment you need.
Nitrous oxide tends to be the right fit if you:
- Have mild to moderate anxiety
- Are you coming in for a shorter, routine procedure
- Need to drive yourself home after the appointment
- Prefer a lighter touch when it comes to sedation
IV sedation may be a better choice if you:
- Experience intense fear or panic around dental visits
- Need multiple treatments done in one sitting
- Have a strong gag reflex that makes dental work difficult
- Have had little success with lighter forms of sedation before
Your dental provider will assess your health history, the nature of your treatment, and your comfort level before recommending the best approach for you. There is no one-size-fits-all answer. What matters most is that you feel safe and cared for.
What to Expect Before and After Sedation
Before Your Appointment
If you’re having nitrous oxide, you can typically eat a light meal a few hours beforehand. IV sedation requires fasting usually for at least six hours to reduce any risk of nausea. Your care team will give you clear instructions ahead of time.
After Your Appointment
With nitrous oxide, the gas is cleared from your system quickly once the mask is removed. Most people feel normal within 10 to 15 minutes and are cleared to drive. With IV sedation, you will need a trusted adult to drive you home and stay with you for a few hours. It’s also best to rest for the remainder of the day.
Is Sedation Dentistry Safe?
Yes, when administered by a trained dental professional, both forms of sedation are considered very safe. Your care provider will review your full medical history and any medications you take before recommending a sedation option. Any dental clinic near you that offers sedation dentistry should have the proper training, equipment, and protocols to monitor your safety throughout the entire appointment.
It’s always a good idea to ask questions before your procedure. A trustworthy dental team will take the time to explain everything and address any concerns you might have.
