Sleep dentistry with General Anaesthesia in Brisbane
What is general anaesthesia?
General anaesthesia is a medically controlled, sleep-like state created with a combination of medicines. These medicines are given just before and during your procedure, usually through a drip and sometimes together with inhaled gases. While the anaesthetic is working, you are fully asleep and unaware of the treatment.
How does it work?
When you are under general anaesthesia, you do not simply feel drowsy – your brain temporarily stops recognising pain signals and reflex responses. This means you will not feel or remember the dental procedure while the anaesthetic is active.
Who looks after your anaesthetic?
Your anaesthetic is administered by a specialist doctor called an anaesthetist. At Dental Nook’s partner hospital facilities, the anaesthetist works with a trained support team. Their job is to keep you safe, comfortable and stable from the beginning of the anaesthetic through to your recovery.
How will I be monitored during dental treatment under general anaesthesia?
Throughout your procedure, the anaesthesia team will:
- Continuously monitor your vital signs such as heart rate, blood pressure and oxygen levels
- Manage your breathing
- Provide pain relief related to the treatment and early recovery
When is general anaesthesia used for dental care?
General anaesthesia can make dental treatment possible for adults with special needs, severe anxiety, strong gag reflexes or complex treatment plans that are difficult to complete in the dental chair. Medication is given via injection or a mask, you drift off to sleep within moments, and your dentist completes the planned work while a team of doctors and nurses supervises you closely in theatre and in the recovery area.
General anaesthetic dentistry at Dental Nook
It is a precisely controlled, temporary state designed to allow you to receive the dental care you need in the most comfortable and stress-free way possible.
When you have treatment under general anaesthesia, you gently fall asleep and remain fully unaware of what is happening. Your brain does not react to pain signals or reflexes during this time, so you do not feel any pain throughout the procedure
General anaesthesia is a medically controlled state in which you are fully unconscious, have no memory of the procedure, and your reflexes are suppressed, allowing dental treatment to be carried out safely, comfortably and free from pain or distress.
General Anaesthetic Dentist for Nervous Patients in Brisbane
For some patients, even routine dental care feels overwhelming. In these situations, general anaesthesia (GA) can be an appropriate sleep dentistry option. It is often recommended for people who have:
- A strong dental phobia
- Severe, ongoing dental anxiety
- A history of traumatic dental experiences
Under GA, you are fully asleep and unaware of the procedure. This deeply unconscious state can continue for several hours after your treatment is finished.
Because you are completely asleep, our dentists can safely complete treatment on several teeth or areas of the mouth in one session, something that is often difficult or impossible with a local anaesthetic alone.
Most patients can return home later the same day, but you must have a responsible adult with you to escort you to and from the hospital and stay with you for at least eight hours after your procedure.
Getting Ready for Dental Treatment under General Anaesthesia
Fasting instructions
-
Morning surgery (around 7:00 am – 8:00 am)
Do not eat or drink anything after 2:00 am. Most people simply avoid food and drink once they go to bed the night before. -
Midday surgery (around 11:00 am – 12:00 pm)
Your last food or drink should be before 7:00 am on the same morning.
Smoking
- Try not to smoke for 24 hours before your procedure. Smoking slows healing inside the mouth. If you need help stopping, speak with your GP before your appointment.
Other important preparation
- Make sure you have arranged an escort home as required by the hospital and anaesthetist.
- Do not wear contact lenses for treatment under GA. Contacts can harm the eyes during surgery. Glasses are fine.
- Bring any usual mobility aids, such as walking sticks or frames.
- If you feel unwell, develop a cold, or your health changes the day before, contact the hospital to let them know.
- Have a bath or shower on the morning of your procedure.
- Wear loose, comfortable clothing with sleeves that can be rolled up easily.
- Choose flat, comfortable shoes (no heels).
What not to wear or bring
- Remove all make-up, nail polish and any removable piercings.
- Avoid moisturisers or lotions on your skin so staff can clearly monitor your colour and oxygen levels.
- Leave jewellery at home or somewhere safe – it should not be brought to the hospital.
- Avoid bringing large bags or suitcases, as storage space is limited.
- You may bring a small book or magazine to help pass the waiting time.
After Your General Anaesthetic Dental Treatment
- When your procedure is finished, you will be moved to the recovery area while still asleep.
- You will wake up there and may notice an oxygen mask on your face – this is routine. Extra oxygen helps your body clear the anaesthetic more quickly.
- If teeth have been removed, it is normal to have gauze or a dressing in your mouth and to notice a small amount of blood.
- In recovery, the team will regularly check your oxygen levels, blood pressure and pulse. A small clip on your finger will automatically monitor your vital signs – this is standard practice.
If you have any questions about your recovery, follow-up care, or sleep dentistry for children, please speak directly with your treating dentist or anaesthetist at Dental Nook.
