Anti-snoring aids: choosing safely

Nasal strips or internal dilators aim to widen the nostrils and are most relevant when airflow is restricted near the front of the nose. They do not open a narrowed throat. A mandibular advancement device holds the lower jaw forward to create more room behind the tongue; poor fit can cause jaw discomfort, tooth movement, excess saliva, or dry mouth.

Position trainers discourage back-sleeping and may suit snoring that clearly changes with posture. Chin straps do not treat an obstructed airway and may be unsuitable when nasal breathing is limited. Obstructive sleep apnoea can present with snoring, witnessed pauses, and gasping, so masking the noise does not show that breathing is adequately treated.

Start by identifying the likely site of obstruction. Note whether congestion, mouth opening, back-sleeping, alcohol, or weight change affects the sound, and ask a sleep partner about pauses or gasping. Treat persistent nasal symptoms according to their cause; allergic rhinitis and chronic sinusitis can both present with congestion, but they may need different management.

Check that any product has clear fitting, cleaning, storage, and replacement instructions. Stop using it if it causes breathing difficulty, choking, significant pain, mouth injury, or a change in your bite. A dentist should assess teeth, gums, jaw joints, and fit before prolonged use of a jaw-advancing device, particularly when there are dental problems or dentures.

Book a clinical assessment before relying on an aid when snoring comes with witnessed breathing pauses, choking, gasping, morning headaches, unrefreshing sleep, concentration problems, or substantial daytime sleepiness. Also seek advice if the snoring began after a new medicine or if nasal blockage is persistent or mainly on one side.

Get urgent medical help for ongoing breathing difficulty while awake, blue or grey lips or skin, chest pain, collapse, or unusual difficulty waking the person. Anyone who is sleepy enough to lose concentration should avoid driving and hazardous work until the cause is assessed and alertness is restored.

Ask where your airway seems to narrow, whether you need an overnight breathing test, and whether a nasal, positional, or jaw-advancing aid is a sensible match. For an oral device, ask who will fit it, how your bite and jaw will be monitored, and what symptoms mean you should stop using it.
