Two people can snore equally loudly and have very different nights. In one, air keeps flowing and the only casualty is a partner's sleep. In the other, the airway closes over and over, breathing stops for seconds at a time, and the brain jolts awake to restart it. The first is simple snoring. The second is obstructive sleep apnoea, a medical condition that deserves a proper assessment.
Noise is not the dividing line, breathing is
Snoring is the sound of relaxed soft tissue at the back of the mouth and throat vibrating as air passes. The airway narrows but stays open. It can be loud enough to drive someone to the spare room and still be harmless to the person snoring.
In obstructive sleep apnoea (OSA), the narrowing goes further. The airway partly or completely collapses, airflow drops or stops for ten seconds or longer, and oxygen levels fall until a brief arousal reopens the throat, often with a snort or gasp. This can happen many times an hour, and the person usually has no memory of it. Over time, repeated drops in oxygen and broken sleep are linked with high blood pressure, heart problems, poor concentration and a higher risk of accidents.
So the useful question is not how loud the snoring is. It is whether the breathing keeps stopping.
Clues you can notice at home
Only a sleep study can confirm OSA, but the pattern of symptoms gives a good hint about which side of the line you are likely on.
| What you or your partner notice | More typical of simple snoring | More typical of sleep apnoea |
|---|---|---|
| Silences followed by a gasp or snort | Not present | Often reported by a partner |
| How you feel on waking | Usually rested | Unrefreshed, even after a long night |
| Daytime sleepiness | Little or none | Can be marked, including when driving |
| Morning headache or dry mouth | Occasional | More common |
| Waking to urinate at night | Not usually | Can happen several times |
| Wider health links | Mainly disturbs others | Associated with blood pressure and heart strain |
Quiet snoring with good energy during the day points towards simple snoring. Loud nightly snoring with pauses, gasping or heavy daytime tiredness points the other way. Blood pressure that is hard to control is another reason to ask about OSA.
When to see your GP
Make an appointment if a partner has seen you stop breathing, if you are sleepy enough during the day that it affects work or driving, or if loud snoring comes with morning headaches and broken sleep. If you ever feel drowsy at the wheel, do not drive until you have been assessed.
Your GP can arrange a sleep study, often done at home with a portable monitor. It counts how many times an hour breathing is reduced or stops, reported as the apnoea-hypopnoea index. That number, together with your symptoms, decides if you have OSA, how severe it is, and which treatments make sense.
The dentist's role starts after the diagnosis
Dentists do not diagnose sleep apnoea. They do sometimes raise the question, because worn teeth from night-time grinding, a scalloped tongue or a crowded airway can be noticed during a check up. If you wake with a sore jaw as well as snoring, our articles on teeth grinding and night guards explain how those problems overlap.
Once a doctor has confirmed OSA, a dentist can make a custom oral appliance called a mandibular advancement splint. It fits over the upper and lower teeth and holds the lower jaw slightly forward, which brings the tongue forward and helps keep the airway open. It is usually considered for mild to moderate OSA, for people who cannot get on with a CPAP machine, and for some people with heavy snoring and no apnoea. CPAP generally remains the first choice for severe OSA. Our guide to oral appliances for sleep apnoea covers fitting, adjustment and suitability in more depth.
Shop-bought snoring devices and what they can miss
Over-the-counter boil-and-bite devices are widely available and much cheaper than a custom appliance. Some people with simple snoring find them helpful. They are less retentive, are not designed to be adjusted step by step, and are not a treatment for diagnosed apnoea. The bigger risk is that they quieten the snoring enough to stop anyone worrying, while the breathing pauses carry on. A custom appliance costs considerably more because it is laboratory made, adjustable and reviewed over time. CPAP machines are prescribed and set up through a sleep service. Our current deals page lists consultation options, and you can ask for a quote at your appointment.
Common questions
Will losing weight stop me snoring?
For some people, yes, or at least it helps. Extra weight around the neck narrows the airway, so weight loss can reduce snoring and lessen the severity of OSA. It works best as part of a wider plan rather than on its own.
Does sleeping on my side help?
Often. Lying on your back lets the tongue and soft palate fall backwards, so side sleeping reduces snoring for many people and can help some with position-related apnoea. It does not replace an assessment if you have warning signs.
My child snores. Is that the same thing?
Occasional snoring is common in children, for example with a cold. Loud snoring most nights, pauses in breathing or restless sleep can be linked with enlarged tonsils or adenoids and should be checked by a GP or paediatrician.
Where to go from here
If you snore but wake refreshed, simple snoring is the likely explanation. If the snoring comes with pauses, gasping or daytime exhaustion, start with your GP and a sleep study. When a diagnosis is in place, the team at Lumi Dental in Melrose Park can talk through whether a custom oral appliance may suit you.
