Short answer: most people who snore do not have sleep apnea, but snoring that comes with pauses in breathing, gasping, morning headaches or heavy daytime tiredness is worth checking. You cannot tell for sure at home. A sleep study is how it is diagnosed, and a dental exam can be a first step in finding out whether you should have one.
Snoring is common. Sleep apnea is a different matter.
Snoring happens when the tissues at the back of the throat vibrate as air moves past. Plenty of people do it occasionally, especially with a cold, alcohol or when sleeping on their back. Obstructive sleep apnea is a condition where the airway repeatedly narrows or closes during sleep, so breathing briefly stops or becomes shallow many times a night.
The two overlap, but they are not the same. That is why the question is not “do I snore?” but “what goes with the snoring?”
Signs worth taking seriously
Take these together. One alone means little, and several at once are a good reason to ask for a check.
- A partner notices pauses in your breathing, followed by a snort or gasp.
- Waking up choking or gasping, or with a racing heart.
- Unrefreshing sleep. You get a full night in bed and still wake up tired.
- Morning headaches or a dry mouth or sore throat on waking.
- Heavy sleepiness in the day, including nodding off when you sit still.
- Trouble concentrating or a short temper that is hard to explain.
- Needing the bathroom more than once a night.
The most useful question to ask someone who shares your bed: have you ever seen me stop breathing, or snort or gasp awake? It is one of the stronger clues, and many people never hear it about themselves.
A note on breath and rest
Many Eastern traditions treat breathing and rest as the foundation of health. Yoga’s breathing practices, for example, emphasise slow, calm breathing through the nose, and traditional Chinese medicine thinks of sleep as the time the body restores itself. We find that a useful way to think about the topic. Calm nasal breathing and a regular sleep routine are good habits for most people, and a good reason to look at sleep habits as part of overall health.
It is a perspective, not a treatment. Breathing practices and good sleep habits can support well-being, but they have not been shown to treat obstructive sleep apnea, and they should not replace getting it checked.
Who is more likely to have it
Sleep apnea can affect anyone, but it is more common with extra weight around the neck, a narrow airway, getting older, being male, or having a family history. It is also frequently missed in people who do not fit the picture, which is another reason to go by symptoms, not stereotypes.
What screening involves
Sleep apnea is diagnosed by a sleep study, either at home or in a lab, interpreted by a physician. Dentists are often well placed to notice the early signs. We look at the shape of the airway and jaw, the throat, wear on the teeth and how you sleep, and we ask the questions screening checklists use. If the picture fits, we refer you for a sleep study.
If apnea is confirmed, there is more than one way to treat it, and the right one depends on how severe it is. CPAP remains the standard first choice for many people, particularly with severe apnea. For some patients, a custom oral appliance is an alternative, as we describe in our posts on oral appliance therapy and oral appliance versus CPAP. You will find more on our sleep apnea page.
Snoring, and tired all the time?
A short exam and a few questions can tell us whether a sleep study is worth your time. There is no obligation, and many patients are glad they asked.
Frequently Asked Questions
Does snoring always mean sleep apnea?
No. Many people snore without having sleep apnea. What raises concern is snoring that comes with other signs: pauses in breathing that a partner notices, waking up gasping, unrefreshing sleep, morning headaches or heavy daytime sleepiness. A sleep study is the way to tell the difference.
Can I tell if I have sleep apnea without a sleep study?
Not reliably. Symptoms and screening questions can show whether a sleep study is worthwhile, but diagnosing sleep apnea and measuring its severity needs a sleep study. That can often be done at home, and a physician interprets the results.
Why would a dentist be involved in sleep apnea?
Dentists see the mouth, jaw and airway every visit and can often spot signs such as a narrow airway, a scalloped tongue or tooth wear from night-time clenching. For patients diagnosed with sleep apnea, a dentist may also provide a custom oral appliance as one treatment option, alongside the physician managing the diagnosis.
Do breathing exercises or yoga help sleep apnea?
Calm breathing, yoga and good sleep habits can support general well-being and are healthy to practise, but they have not been shown to treat obstructive sleep apnea. If you suspect you have it, they should sit alongside a proper evaluation, not replace it.
What should I do if I think I have sleep apnea?
Start by asking whoever shares your bed what they notice, then book an exam. We will go through your symptoms and examine your airway and teeth, and if it looks likely, refer you for a sleep study. Untreated sleep apnea is associated with other health problems, so it is worth finding out.
