Oral Appliance Therapy vs CPAP: Which Sleep Apnoea Treatment Is Right for You?
If you’ve been told you snore loudly, wake up gasping, or feel exhausted no matter how early you get to bed, you’re not alone — and you’re not stuck with only one treatment option. Most people assume a sleep apnoea diagnosis means a CPAP machine for life. In reality, a custom-fitted oral appliance, made and monitored by a dentist trained in dental sleep medicine, is a proven alternative for many patients — and for some, it’s the more comfortable, more consistently-used option.
At Doncaster Dental, we work alongside a visiting sleep physician to diagnose and manage snoring and obstructive sleep apnoea for patients across Doncaster, Templestowe, Bulleen and the wider Manningham area. Here’s how the two main treatment paths compare, so you can have an informed conversation with your dentist or sleep physician about which one fits your life.
How Do You Know If It’s Snoring or Sleep Apnoea?
Not everyone who snores has sleep apnoea — but loud, frequent snoring accompanied by any of the following is worth having assessed:
- Choking or gasping sounds during sleep
- Excessive tiredness during the day, even after a full night’s sleep
- Morning headaches or a sore, dry throat on waking
- Trouble concentrating or noticeable memory lapses
- Low mood, anxiety, or a drop in libido
A sleep study is the only way to confirm a diagnosis and grade its severity. We can arrange this as part of your sleep apnoea assessment at our Doncaster Road practice.
CPAP: The Long-Standing Gold Standard
CPAP (Continuous Positive Airway Pressure) delivers a steady stream of air through a mask worn overnight, keeping the airway open by gentle pressure. It’s highly effective, especially for moderate to severe sleep apnoea, and remains the first treatment most sleep physicians recommend.
Where it falls down for many patients is comfort and consistency. A mask, hose and machine every night is a big adjustment — dry mouth, mask leaks, noise, and simply feeling too claustrophobic to wear it are common reasons people stop using CPAP within the first year, even when it’s working.
Oral Appliance Therapy: A Smaller, Quieter Alternative
A custom oral appliance is worn like a mouthguard or orthodontic retainer. It gently holds the lower jaw slightly forward, which keeps the airway from collapsing during sleep — no mask, no hose, no machine noise.
Because it’s made from a precise mould of your own teeth and adjusted over several visits, it tends to be far better tolerated night after night than CPAP, which is one of the main reasons dentists and sleep physicians increasingly recommend it, particularly for mild to moderate obstructive sleep apnoea or as an option for patients who’ve tried CPAP and can’t stick with it.
Comparing the Two Side by Side
| Oral Appliance Therapy | CPAP |
Comfort | Small, custom-fitted, worn like a mouthguard | Mask + hose + machine — bigger adjustment |
Best suited to | Mild to moderate sleep apnoea | Moderate to severe sleep apnoea |
Noise | Silent | Machine hum; some find it disruptive |
Travel | Compact, easy to pack | Requires the full machine setup |
Typical adherence | Higher — easier to wear consistently | Often lower long-term due to comfort issues |
Who provides it | A dentist trained in dental sleep medicine | A sleep physician / CPAP provider |
Which One Is Right for You?
This isn’t a decision to make alone — it depends on the severity of your sleep apnoea, confirmed through a sleep study, and your own comfort and lifestyle. For milder cases, or where CPAP hasn’t been tolerated, an oral appliance is often the more realistic long-term solution simply because people actually wear it. For more severe cases, CPAP may still be the safer first-line treatment, sometimes alongside an oral appliance. In rare, specific cases where neither option is suitable, surgical referral is available as a last resort.
The best starting point is a conversation with our team — we’ll talk through your symptoms, arrange a sleep study with our visiting sleep physician if you haven’t had one, and explain honestly whether oral appliance therapy is likely to suit you before you commit to anything.
Frequently Asked Questions
Structured for FAQPage schema — each Q&A below can be dropped directly into the page’s JSON-LD.
Can a dentist actually treat sleep apnoea?
Yes. Dentists trained in dental sleep medicine can fit and monitor custom oral appliances that treat mild to moderate obstructive sleep apnoea, working alongside a sleep physician who confirms diagnosis and severity through a sleep study.
Is an oral appliance as effective as CPAP?
For mild to moderate obstructive sleep apnoea, oral appliance therapy can be similarly effective, and because it’s more comfortable for many people, it’s often used more consistently than CPAP. For severe sleep apnoea, CPAP is generally still considered the first-line treatment.
How long does it take to get a custom oral appliance?
After a sleep study confirms diagnosis, the appliance is custom-made from an impression of your teeth and typically requires a few follow-up visits to fine-tune the fit and jaw position for maximum effectiveness and comfort.
Will my health fund cover oral appliance therapy?
Coverage varies by fund and policy level. Our team can help you check what your extras cover includes before you begin treatment.
What happens if oral appliance therapy doesn’t work for me?
If symptoms don’t improve, we’ll reassess with your sleep physician — options include adjusting the appliance, moving to CPAP, or in rare and specific cases, a surgical referral.
