How it works
During sleep the tongue and soft tissues fall back and narrow the airway. An oral appliance holds the lower jaw a few millimetres forward, which carries the tongue forward with it and keeps the space behind it open.
It is worn only at night. It is not a mouthguard and it is not the device sold in pharmacies: it is made to your teeth and adjusted in small controlled steps.
Who it is for
- People who snore heavily, with or without diagnosed apnea
- People with diagnosed mild to moderate obstructive sleep apnea
- People with any severity of apnea who cannot tolerate CPAP
- People who travel constantly and will not carry a machine
It is not the first choice for severe apnea, where CPAP remains the better treatment. See snoring and sleep apnea for where the boundary sits.
How the treatment runs
- Assessment, including your sleep study result if you have one, and an examination of your teeth, gums and jaw joint. Enough healthy teeth are needed to hold the appliance, and active gum disease has to be dealt with first.
- Impressions and a bite record, which set the starting jaw position.
- Fitting, usually two to three weeks later, with instruction on how to insert, remove and clean it.
- Titration. Over the following weeks the advancement is increased in small steps until snoring settles and you feel rested. This gradual part is what a pharmacy device cannot do.
- Confirmation. Where apnea was diagnosed, a repeat sleep study with the appliance in place confirms it is working.
- Review, ongoing, to check the fit, the bite and the jaw joint.
The honest downsides
Extra saliva at first. Morning jaw tenderness for the first couple of weeks. A risk of slow changes to the bite over years of use, which is why the reviews exist. And it needs wearing every single night to do anything at all.
