SleepDoctor Oral Device

Tax included.
The SleepDoctor Oral Device is a mouthpiece that treats sleep apnoea and loud snoring. It works by holding your jaw in the right position to keep your airway open, providing effective relief from snoring and sleep apnoea.

How does the SleepDoctor Oral Device work?

The SleepDoctor Oral Device is a boil-and-bite mouth guard for snoring and sleep apnoea.

The fully adjustable design holds your jaw in the right position while you sleep. This opens your airway and helps you breathe easily and quietly. The SleepDoctor Oral Device moulds to fit around your teeth, helping you take control of snoring and sleep apnoea.

  • Soft, inner plastic gives a secure, comfortable fit
  • Harder outer plastic protects against general wear and tear
  • Fully adjustable screw mechanism
  • Portable and easy to care for
  • Open design lets you sleep with your mouth open
How it works

When you sleep, your muscles relax, including the ones in your throat. This relaxation can cause your airway to narrow, making it difficult for your lungs to inhale and exhale the amount of air you need.

If your airway narrows, the air you breathe is pulled through it faster. This causes the soft tissue in the airway to dehydrate and vibrate. The sound this makes is what you hear as snoring. For some people, the airway becomes so narrow that the walls of the airway stick together and close up. This usually happens for around 10-30 seconds at a time, but can occur for longer. This is known as an apnoea.

The SleepDoctor Oral Device treats snoring and mild-to-moderate sleep apnoea by holding your jaw forward during sleep. This helps to keep your airway open, stopping it from collapsing during the night and helping you to breathe easily.

Oral devices are a recommended treatment by the NHS for loud snoring and sleep apnoea.


The SleepDoctor Oral Device is BPA and Latex-free.
