Are you prone to snoring or suffer from mild sleep apnoea?
For mild to moderate apnoea a device called Mandibular Advancement Device is very effective in treating snoring.
It is like a double mouthguard that goes over both the upper and lower teeth. The upper and lower mouthguards clip together, so that the jaw is held forward during the night and this helps keep the airway open.
For severe form of obstructive sleep apnoea you may need alternate treatments and is best to talk to your GP.
