Sleep Apnoea

Designer Smiles is renowned as the top sleep clinic in Sydney, where patients can undergo sleep studies and consultations with sleep specialists to address sleep apnea.
We understand the impact that sleep apnea can have on your quality of life. Sleep apnea is a common sleep disorder characterised by pauses in breathing during sleep, often accompanied by loud snoring and restless sleep. Left untreated, sleep apnea can lead to serious health problems such as high blood pressure, heart disease, and stroke. That's why we're dedicated to providing effective treatment options to help you breathe easier and enjoy a better night's sleep.


  • Apnea Hypopnea Index>5 in a PSG study with daytime symptoms. Apnoea = period of complete cessation of oronasal airflow for minimum of 10s; period of more than 50% reduction of oronasal airflow with a decrease of more than 3% of ongoing saturated O2 = hypopnea.
  • recurrent sleep-induced collapse of the pharyngeal airway leading to hypoxaemia, hypercapnia, with arousal from sleep required to re-establish airway patency
  • Obstructive: continued/raised diaphragm EMG activity and/or thoracoabdominal wall movement; thoracoabdominal paradox may be present
  • Central: absent diaphragm EMG and thoracoabdominal movement
  • Mixed: components of both

Understanding Sleep Apnea

Sleep apnea occurs when the muscles in the throat relax excessively during sleep, causing the airway to become partially or completely blocked. This results in interruptions to breathing, leading to drops in oxygen levels and disruptions to sleep patterns. Common symptoms of sleep apnea include:

  • Loud snoring
  • Pauses in breathing during sleep
  • Excessive daytime sleepiness
  • Morning headaches
  • Difficulty concentrating
  • Irritability

If you suspect that you or a loved one may have sleep apnea, it’s important to seek diagnosis and treatment promptly to prevent potential complications. Looking for a sleep apnea test in Sydney? Visit Designer Smiles for accurate diagnosis and tailored treatment plans.


Comprehensive Treatment Options

At Designer Smiles, we offer a range of effective treatment options for sleep apnea tailored to your individual needs. Our experienced team will work closely with you to determine the most appropriate course of action based on your symptoms, medical history, and personal preferences.

Custom Oral Appliances: Oral appliances are a popular treatment option for mild to moderate sleep apnea. These custom-made devices are worn during sleep to help keep the airway open by repositioning the jaw or tongue.

Continuous Positive Airway Pressure (CPAP) Therapy: CPAP therapy is a highly effective treatment for moderate to severe sleep apnea. It involves wearing a mask connected to a machine that delivers a continuous stream of air to keep the airway open during sleep.

Lifestyle Modifications: In addition to medical treatments, making lifestyle changes such as losing weight, quitting smoking, and avoiding alcohol and sedatives before bedtime can also help improve symptoms of sleep apnea.

Designer Smiles is recognised as the best sleep clinic in Sydney, offering comprehensive services for sleep disorders.

Dr Sarkis is the maestro of cosmetic dentistry….for years I suffered with 2 slightly darker front teeth due to a childhood accident. I’ve had composite veneers before but nothing compared to the composite veneers Dr Sarkis did……now I feel so confident smiling again……Dr Sarkis I can’t thank you enough…

Monica McKenzie

Quite literally the best dentist I’ve been to in a lifetime. Dr Natasha Koelmeyer specifically is just a wonderfully kind and gentle Doctor. Must also mention that the head specialist here is also second to none. Their knowledge (goodness they know their stuff) their approach, their kind and gentle manner - my daughter actually enjoys going to the dentist. They’ve got a really considered patient centric mentality. I wouldn’t go anywhere else, every single person there including the reception staff is a star. Thank you Designer Smiles!

Michelle Lacasse

My journey with Dr Sarkis began about 10 years ago. I did not realise that I had lacked self confidence and shone away from "my true smile". Dr Sarkis was honest, reassuring and professional throughout my process and not only was he able to achieve that perfect smile but achieve same without compromising the health of my teeth and gums.The ongoing care at Designer Smiles is 5 star whether it is a routine check, clean minor or major dentistry. Thank you Dr Sarkis and also your team.

Christina Vergotis

I found Designer Smiles from one of their YouTube videos showcasing the Icon treatment to fix white spots on teeth. Dr. Sarkis Nalbandian's consultation provided me with a thorough plan and showed me how their practise could give me predicable results for my concerns. I knew I was in safe hands. I had Kristy Gupta perform both of my procedures and she was very professional and so kind. I am very happy with my results!

Winsome Kain

I cannot express how grateful I am for Sarkis and the team at Designer Smiles. Around 11 years ago my life changed when Sarkis first transformed my smile with composite veneers. This month, with my original teeth in tact I returned to have my composite veneers upgraded to porcelain. I was amazed that Sarkis and his team could do this without an injections, no pain and whilst still keeping my original teeth in tact. I absolutely love the result and I would highly recommend that anyone that is unhappy with their smile in any way, must visit designer smiles

Matt Williams

Started my treatment with the team at Designer Smiles in 2019. Had other dental treatments including Maxillofacial, expanders, straightening and gum grafting but out of all the procedures and surgeries Dr. Sarkis was the key as he was applying the ‘finishing product’ which included composite veneers. I am gobsmacked by the incredible job done. He talks the talk and definitely walks the walk. And his support team there are simply incredible and make you feel part of a family not just another dental clinic to take your money. Can not recommend highly enough. Customer for life here!!
