IV sedation at the dentist: what to expect, step by step

Before the day

Most practices start with a consultation to check your medical history and medicines, talk through the treatment and agree whether sedation suits you. It's a good moment to say exactly what worries you.

You'll be told whether to eat beforehand and what to bring. Arrange an adult to come with you, take you home and stay with you afterwards: practices won't sedate you without one.

On the day

A small tube (cannula) is placed in your hand or arm, and the sedative is given slowly. Within minutes most people feel calm and drowsy. Your breathing, pulse and oxygen level are watched throughout.

You'll still have a local anaesthetic to numb the area, often after the sedative has taken effect, so many people don't remember the injection at all.

Afterwards

You'll rest at the practice until you're steady, then go home with your escort. Expect to feel sleepy for the rest of the day. Don't drive, drink alcohol, use machinery or make important decisions until the next day, and follow your practice's written advice.

Questions worth asking the practice

Who gives the sedation: the dentist or a separate sedationist? How much is it per hour, and how long will my treatment take? Can I have sedation for a check-up or cleaning, or only for treatment? What happens if I need more treatment later?
