"Sleep dentistry" is a popular term, not a medical one. It can mean anything from sedation, where you are relaxed and drowsy, to a general anaesthetic, where you are unconscious. Which option is right depends on your health, your treatment and the setting, and is decided with your dentist and anaesthetist.
The options
The Better Health Channel describes several ways to make dental treatment more manageable. They differ in how deeply they affect you and in who can provide them.
| Option | What it involves | Usually provided by |
|---|---|---|
| Local anaesthetic | An injection numbs the area being treated. You are fully awake. | Your dentist |
| Relative analgesia (“happy gas”) | You breathe a gas mixture through a small nose mask that helps you relax. You stay awake. | Your dentist |
| Anti-anxiety tablets | A tablet taken before treatment to reduce anxiety. | Prescribed by your dentist or doctor |
| IV sedation (conscious or “twilight” sedation) | Medicines through a drip make you relaxed and drowsy. You may drift off and may remember parts of treatment. | A dentist with sedation training and endorsement, or a medical practitioner such as an anaesthetist |
| General anaesthetic | Medicines make you unconscious for the treatment. | A specialist anaesthetist, with the dentist |
Local anaesthetic is usually still used with sedation or a general anaesthetic, to numb the area and help with pain afterwards.
Who it may be suitable for
Sedation or a general anaesthetic may be considered when:
- dental anxiety is so severe that treatment cannot otherwise go ahead
- treatment is extensive or complex, such as removing impacted wisdom teeth
- a strong gag reflex makes treatment very difficult
- a person has a disability or medical condition that makes treatment in the chair difficult
- a young child needs a lot of treatment.
Not everyone needs sedation or a general anaesthetic, and not everyone is suitable for it in a dental practice. Your dentist and anaesthetist will assess you first. For some people, treatment in a hospital or day surgery is the safer choice.
Where treatment takes place
Dental sedation and general anaesthesia may take place in a hospital, a day surgery, or a dental practice that has the facilities, equipment, monitoring and staff required by Australian guidance. ANZCA publishes standards for the facilities and monitoring needed wherever anaesthesia or sedation is given. In Victoria, mobile anaesthetic services that work in dental practices are regulated by the Department of Health.
Your anaesthetist’s role
When an anaesthetist provides your sedation or anaesthetic, their only job during the procedure is you. They:
- review your health and medicines beforehand
- explain the plan, the alternatives and the risks, and check that you agree
- give and adjust the medicines and monitor your breathing, heart rate, blood pressure and oxygen throughout
- look after you as you wake up, and decide with the team when you are ready to go home.
The dentist concentrates on your dental treatment.
Preparing for dental sedation or anaesthesia
- Follow your fasting instructions exactly. For IV sedation and general anaesthesia the rules are usually the same as for an operation. Read fasting before anaesthesia.
- Tell your dentist and anaesthetist about all your medicines, including weekly injections for diabetes or weight management.
- Arrange a responsible adult to take you home and stay with you.
- Wear loose, comfortable clothing with sleeves that roll up easily.
- Do not drive, drink alcohol or make important decisions for at least 24 hours afterwards.
Risks
Common effects include drowsiness, feeling sick, and a sore or numb mouth. Less commonly, sedation can slow your breathing, which is why you are monitored throughout. Serious complications are rare. Your anaesthetist will explain the risks that are relevant to you. See risks and side effects.
