General Anaesthesia

A general anaesthesia involves administering anaesthetic medication through your veins to put you to sleep, so that you will be in an unconscious, relaxed and pain-free state throughout your entire dental procedure.

What is General Anaesthesia?

While your dentist completes your dental treatment, your sleep-like state will be induced, controlled and well looked after by an anaesthesiologist (a provider medical professional) within a specialised medical room.

Why Have Your Dental Procedure Under General Anaesthesia?

Dental Phobia

For patients undergoing a dental surgical procedure, and have feelings of anxiety or a phobic condition, a general anaesthesia can help put you to sleep whilst we take care of your dental treatment.

Invasive Dental Procedures

For some patients, a general anaesthesia may be a rite of passage in confidently completing more invasive dental treatment (for example, wisdom tooth surgery, multiple tooth extractions, placement of multiple dental implants or All-on-4, etc) or even combinations of these.

Single Visit

Dental treatment plans that may otherwise be too excessive for you to complete all in one go can now be fulfilled in one visit with a general anaesthesia.

Certain Medical Conditions

For patients with certain medical conditions such as severe psychiatric conditions, severe learning difficulties, etc, a general anaesthesia may be the solely mode to which they can accept dental treatment safely.

What Does the Procedure Involve?

Stage 1: Initial Consultation

  • Your dentist will take time to explore your concerns and conduct a general health assessment, then discuss a suitable mode of having your dental treatment.
  • If sedation or a general anaesthesia is agreed upon, you will be advised on how long you will need to fast before the procedure, what time to arrive in advance of your procedure, and the post-operative care required (see below).

Stage 3: Post-Operative Care

After your treatment, the anaesthetic effects will continue to linger so you will need to plan ahead. It is necessary for a reliable family member or friend to accompany you home via appropriate transport and take care of you after. You also cannot drive, operate any machinery, drink alcohol, or go to work for the next 24 hours. It is normal not to remember full details about your appointment.

Stage 2: General Anaesthesia and Dental Treatment

  • On the day of your appointment, your medical team will conduct pre-operative checks to ensure you can safely undergo general anaesthesia.
  • You will then lay on a comfortable bed whilst being induced to sleep in a slow and comfortable manner. Once you are in an unconscious, relaxed and pain-free state, your dental treatment will be completed.
