Sedation Dentistry

We are a professional sleep dentistry service led by Dr Alexander Lam.

We provide dental anaesthesiology care, working with dentists to provide relief for patients who are anxious or uncomfortable having dental treatment, and who are undergoing procedures they find unpleasant.

Dr Alexander Lam performs Intravenous Sedation.  He understands your procedure and how to ensure your safety and comfort during your dental appointment.  

Dental Intravenous Sedation is also known as twilight, moderate or conscious sedation, and if you need dental sedation or sleep dentistry in South Australia, then you have come to the right place.

Adelaide Sedation Dentistry services many dental practices all over Adelaide including specialist Periodontic, Implant Surgery, Oral and Maxillofacial Surgery and Prosthodontic practices.

Any surgical or invasive procedure carries risks. Before proceeding, you should seek a second opinion from an appropriately qualified health practitioner.

If you feel anxiety at the thought of a visit in the dental chair, talk to us about sedation dentistry.

Most forms of sedation used in dentistry allow you to remain conscious but relaxed, helping to ease the tension of undergoing dental procedures. 

Methods of Sedation

There are several methods of sedation available:

Nitrous oxide is a common sedation technique. A small mask is fitted over your nose, and you inhale a sweet-smelling gas while the procedure is taking place. Nitrous oxide causes a relaxed feeling during your dental procedures. The effect wears off just minutes after the mask is removed, allowing you to immediately resume your normal activities.
Intravenous, or IV, sedation consists of a sedative administered directly into your bloodstream. IV sedation is good for shorter procedures. Administering the medication directly into your bloodstream means immediate results. You may feel as if you were asleep during your procedure, and you will need a companion to accompany you, as grogginess is normal following IV sedation.
Oral sedation can be used for mild to moderate dental anxiety. You will be given a medication to be taken approximately an hour before your appointment. Oral sedation will leave you feeling very relaxed, and you may not even remember all of the procedure. You will need to be accompanied to your appointment by a friend or family member as oral sedation can take several hours to wear off.

You will be monitored during your appointment to ensure that you are safe during the procedure.

Benefits of Sedation

Sedation dentistry offers several benefits:

  • It allows you to complete dental work in fewer visits.
  • It helps alleviate anxiety and leaves you relaxed after your procedure.
  • It can keep you from remembering the sounds and smells often associated with dental anxiety.
  • If you are interested in sedation dentistry or have questions or concerns, please contact our clinic for more information. We will be happy to help you decide what’s right for you.

For Patients

If your dentist has recommended a dental procedure that makes you really nervous, or if you have a dental phobia, now there's help for you in the comfort and safety of your own dentist's rooms. You don't need to experience the stress of a full anaesthetic in a hospital. All you need to do is to ask your dentist to contact us at Adelaide Sedation Dentistry. We can then arrange to meet with your dentist and discuss how we can work in his or her practice to provide gentle, safe "twilight anaesthesia" to relieve your anxiety.


Monday - Saturday. Please call or email for availability on a particular time/day. As Dr Lam is quite busy, it is best to have some flexibility in your booking times.  

For Dentists

IV sedation is a safe, effective way to complete dental treatment on anxious, phobic, difficult to anaesthetise or gagging patients. It is also a great way to relieve the discomfort of long or uncomfortable procedures, such as extractions, third molar removal, endodontic, implant and other surgical procedures.

It can be used reliably for procedures up to two hours duration. On some patients, sedation times of three to four hours can be achieved, depending on patient safety (relating to doses required), cooperation and comfort. This will result in longer recovery times.

This is how our team works to ensure clinical excellence:

  • Careful patient selection. As a guideline, we work principally with patients aged from 12-70 years, who are in good health (ASA1 and ASA2).
  • Thorough patient preparation and post-operative care.
  • Meticulous patient monitoring. Patients' vital functions are monitored via Clinical Observations, Blood Pressure, Pulse Oximetry, ECG and End Tidal CO2.
  • Titration of sedative drugs. Small tailored doses of sedative drugs are administered throughout the procedure to maintain exactly the right effect for the patient.
  • Intravenous analgesia prior to uncomfortable stimuli.
  • Intravenous dexamethasone if indicated. We ensure postoperative comfort for every patient.
  • Oxygenation of the patient.
  • Adelaide Sedation Dentistry always has emergency equipment and reversal drugs on hand.

No special equipment or training is required by the practice staff beyond what AHPRA requies as standard- that is: all staff require the normal CPR (including defibrillation) and life support training, such as the Applied First Aid Course by St John’s Ambulance or Australian Resuscitation Council's Advanced Life Support Course. 

Oxygen is required in the surgery (all patients receive oxygen supplementation), however it can be supplied by Dr Lam by prior arrangement.

If you would like to use Dr Lam to provide Sedation Services for your practice or to find out a suitable practice to send your sedation patients, please contact us and we would be delighted to make arrangements.
