If you’re seriously considering IV sedation, there’s a good chance the question underneath all your other questions is this one: is it actually safe? That’s a completely reasonable thing to want a straight answer to before you agree to have any medication delivered into your bloodstream. Here’s what’s actually true.
The short answer
Yes. IV sedation is a well-established technique that’s been used safely in dentistry and medicine for decades. When it’s provided by a trained, licensed dentist with proper monitoring in place — which is the standard of care in Alberta and across Canada — serious complications are rare. The dentists and staff administering it are specifically trained and licensed for it, and monitoring your vital signs throughout the procedure is a routine, expected part of every appointment, not an extra precaution.
That doesn’t mean risk is zero — no medical or dental procedure is completely without risk — but it does mean the profession has had a long time to refine how this is done safely, and the systems in place reflect that.
Why IV sedation has such a strong track record
It’s used across medicine, not just dentistry
IV sedation isn’t a dental invention. The same general approach — sedating a patient through an IV line while monitoring their vital signs — is used for procedures across medicine, from colonoscopies to minor surgeries. Dentistry adapted a technique that already had a long history of safe use elsewhere, and dental-specific training and licensing were built on top of that foundation.
Monitoring is built into every appointment
Throughout an IV sedation appointment, your dental team monitors your vital signs continuously using standard sedation monitoring equipment, so they can see exactly how you’re doing at every moment and respond immediately if anything needs adjusting. This kind of monitoring — along with having appropriate emergency protocols and training in place — is considered standard of care for sedation dentistry, not an optional add-on. It’s one of the biggest reasons the safety record for properly administered IV sedation is as strong as it is.
Your provider’s training and licensing matter
Not every dentist is licensed to provide IV sedation — it requires specific additional training and certification beyond general dental licensing, along with ongoing requirements to maintain that certification. Dr. Hartley is licensed by the Alberta Dental Association to provide sedation dentistry. When you’re researching any provider for IV sedation, their sedation licensing (not just their general dental license) is one of the most meaningful things to check.
“But what if something goes wrong?”
It’s a fair question, and one that anxious patients often think about more than they say out loud. The honest answer is that dental offices offering IV sedation are required to have monitoring and emergency protocols in place specifically to catch and manage the rare situation where something doesn’t go as expected — that’s the entire point of the monitoring equipment and staff training discussed above. A licensed sedation provider isn’t just hoping nothing happens; the whole setup is built around being able to respond quickly if something does.
We won’t get into the specifics of what that equipment or those protocols look like here — partly because it varies by office and partly because it’s simply more than most patients need or want to know in detail. What matters is that it exists, it’s a licensing requirement, and it’s something you’re welcome to ask your dentist about directly at your consultation.
What actually affects your personal level of risk
Your individual risk with IV sedation depends on factors that are specific to you — things like your general health, any medications you’re currently taking, and your medical history. This is exactly why every patient goes through a health history review before IV sedation is scheduled, not after. Certain health conditions may affect your sedation options, and your dentist will review your history with you at consultation to make sure IV sedation is the right and safe choice for your situation specifically — or recommend an alternative if it isn’t. (More on that in Am I a Candidate for IV Sedation?.)
Being upfront with your dentist about your full health history, including anything you might not think is relevant, is the single biggest thing you personally control here.
Questions worth asking before you book
If safety is on your mind — and for most people considering IV sedation, it is — these are reasonable questions to bring to a consultation:
- Is the sedating dentist specifically licensed for IV sedation, not just general dentistry?
- What monitoring is used during the procedure?
- What happens if my health history changes between now and my appointment?
- Who do I contact if I have concerns after I get home?
A good sedation provider will answer these directly and without making you feel like you’re being difficult for asking.

Frequently Asked Questions
Is IV sedation riskier than oral sedation or nitrous oxide?
IV sedation involves a deeper level of sedation than oral sedation or nitrous oxide, which is exactly why it requires additional dentist licensing and more intensive monitoring during the appointment. For patients who are good candidates for it, it’s considered a safe option with that monitoring in place.
Is IV sedation safe for older adults?
Age alone doesn’t rule someone out, but it is one of many factors your dentist considers as part of your health history review. This is decided individually at consultation, not by a blanket age rule.
How do I know if my dentist is actually licensed for IV sedation?
Ask directly — a dentist offering IV sedation should be able to tell you their specific sedation licensing status without hesitation. In Alberta, sedation licensing is issued by the Alberta Dental Association and is separate from general dental licensure.
What if I have a reaction during the procedure?
Your team is monitoring your vital signs throughout the procedure specifically so they can identify and respond to any changes right away. This is a routine part of every IV sedation appointment, not something that only kicks in if there’s a problem.
