This is general information, and every patient’s situation is different. Please contact your dentist or our team for guidance specific to you.
Not knowing what to expect is one of the biggest sources of anxiety about any medical or dental procedure. So here’s the appointment laid out in order, from the days before to the morning after, including exactly who’s keeping an eye on you throughout.
Before your procedure day
At your consultation, your dentist reviews your health history and confirms IV sedation is right for you, then talks you through your pre-appointment instructions — including not eating or drinking anything for at least 6 hours beforehand, and arranging a ride, since you won’t be able to drive yourself home. If your dentist gives you different guidance for your specific situation, follow that instead. We’ve put together a full pre-appointment checklist here: What to Bring to Your IV Sedation Appointment: Pre-Op Checklist.
When you arrive
Come in comfortable, loose-fitting clothing, and bring the person driving you — they’ll need to be reachable, and often present at the office, for when you’re ready to be discharged. Your team will confirm your health history and answer any last questions before starting anything.
Getting the IV started
A small IV line is placed in your hand or arm — this feels similar to a routine blood draw, a brief pinch rather than ongoing discomfort. Many patients say this is the part they were most nervous about and the part that turns out to be the least eventful.
During the procedure — who’s watching you, and how
This is usually the question underneath the question for anxious patients: am I actually being looked after while I’m not fully aware of what’s happening?
The answer is yes, continuously. Throughout your procedure, your dentist and trained staff monitor your vital signs the entire time, so they always know how you’re doing and can adjust your sedation level as needed. This monitoring is a routine, required part of every IV sedation appointment — not something that only happens if there’s a concern. You’re never left alone; someone trained specifically in sedation monitoring is with you for the full procedure.
Most patients feel deeply relaxed and drowsy during this part, and many doze off entirely. It’s common to have little to no memory of this portion of the appointment afterward.
When it’s over
Once your procedure is finished, you’ll be moved to a recovery area where staff continue to check on you as the sedation starts to wear off. You’ll stay until your team is confident you’re ready to be discharged into the care of whoever drove you — this isn’t a fixed number of minutes, it depends on how you personally respond.
Getting home and the rest of your day
The person who drove you will receive your post-operative instructions, since you may not fully retain them yourself right away. Plan to go straight home and rest for the remainder of the day. You’ll likely feel groggy or drowsy even after the deepest effects wear off within the first hour or so — that grogginess is normal and expected, not a sign anything went wrong.
Don’t plan to make important decisions, sign anything important, or return to work or driving for the rest of the day. If anything feels off once you’re home, your dental office wants to hear from you — don’t hesitate to call.
The next morning
Most patients feel back to fully normal by the following morning. Recovery time varies by person and by procedure, so if your dentist gave you different guidance for your specific situation, follow that instead of this general timeline.

Frequently Asked Questions
Am I ever left alone during IV sedation?
No. Someone trained in sedation monitoring is with you throughout the entire procedure, watching your vital signs continuously.
How long does the whole appointment take, start to finish?
It varies by procedure. IV sedation itself is often chosen specifically because it allows longer or more complex treatment to be completed in a single visit — your dentist will give you a time estimate specific to your treatment plan at consultation.
Will I feel any pain while the IV is being placed?
Most people describe it as a brief pinch, comparable to a routine blood draw, rather than ongoing discomfort.
What if I wake up or become aware during the procedure?
Your sedation level is monitored and adjusted throughout by your dental team specifically so this doesn’t happen unmanaged — if you show any signs of discomfort or awareness, they can adjust accordingly in real time.
Can I go back to work the same day?
No — plan to rest for the remainder of the day. Most patients feel fully normal by the next morning, but always follow your dentist’s specific guidance for your procedure.
