Why we snore
Snoring occurs when air flows past narrowed points in the throat during sleep and sets the soft tissue vibrating. During sleep the muscles relax, the tongue falls back and the throat becomes narrower. When the air then passes through this narrow point, the soft palate begins to flutter, producing the typical sound.
Several factors encourage snoring:
- Sleeping on the back, where the tongue falls back especially easily.
- Excess weight, because tissue also gathers in the throat area.
- Alcohol or sedatives in the evening, which relax the muscles further.
- Obstructed nasal breathing, for example with a deviated septum or a cold.
- Age, because tissue loses tension over the years.
When snoring is harmless and when it is not
Plain snoring without breathing pauses is medically harmless in most cases. It mainly disturbs the sleep of others but has no health consequences for the person snoring. This is known as primary snoring.
The situation is different when snoring comes with pauses in breathing. In obstructive sleep apnoea (OSA), the throat collapses completely during sleep again and again, so that breathing stops for seconds at a time. The body briefly wakes each time to draw breath, often without the person noticing. Signs of this include:
- Observed breathing pauses reported by a bed partner.
- Loud, irregular snoring with gasping for air.
- Marked daytime tiredness and difficulty concentrating despite enough hours of sleep.
- Restless sleep, morning headaches or a dry mouth.
Untreated sleep apnoea can put strain on the cardiovascular system. This is why the distinction between harmless snoring and a possible sign of OSA matters so much.
What a snoring appliance is
A snoring appliance, known technically as a mandibular advancement device, consists of two connected splints for the upper and lower jaw. It holds the lower jaw in a slightly forward position during sleep. This draws the tongue forward with it, the throat stays more open, and the air flows more smoothly. The tissue vibrates less, and snoring becomes quieter or stops.
The appliance works purely mechanically and only for as long as it is worn. It does not remove the cause of snoring; it improves the conditions in the airway night after night.
How it differs from a night guard
A snoring appliance is often confused with a night guard, but it serves a quite different purpose. A night guard protects the teeth from the mechanical consequences of nightly grinding and clenching and relieves the muscles. It does not move the jaw.
The snoring appliance, by contrast, deliberately moves the lower jaw forward to keep the airway open. A standard night guard therefore does not help against snoring, and a snoring appliance does not replace protection against bruxism. Anyone with both problems needs a professional assessment of how the two can be combined. You will find an overview of the different appliance types in our comparison of dental splints.
Who it suits
A snoring appliance is mainly an option in these situations:
- For primary snoring that disturbs sleep but occurs without breathing pauses.
- For mild to moderate obstructive sleep apnoea, after a medical diagnosis.
- When a CPAP machine is not tolerated, or as an additional option when travelling.
The appliance is not suitable for severe sleep apnoea, which usually requires other methods. We also check the conditions carefully in the case of markedly loose teeth, advanced periodontitis or jaw joint complaints. If there is a functional disorder of the jaw, we clarify this beforehand as part of TMJ treatment.
Why sleep apnoea must be assessed medically first
This is the crucial point: if sleep apnoea is suspected, it must first be assessed by sleep medicine. Only a sleep study shows whether breathing actually stops during sleep and how severe the disorder is. This diagnosis is made by a physician, not by the dental practice.
We then make the snoring appliance in coordination with the treating physician. This ensures that the appliance matches the diagnosis and that the success of the treatment can be reviewed medically. An appliance without a prior assessment can mask a serious problem without treating it.
How the fitting works
Once the indication is clear, fabrication begins with an impression or a digital scan of both jaws. From this the laboratory produces an individually fitted appliance made of firm resin. When it is fitted, we set the forward position of the lower jaw gently at first and increase it step by step, until the snoring eases and the appliance sits well. This careful adjustment protects the jaw joint and improves comfort.
In the first weeks, some getting used to it and occasional morning tension in the jaw are normal. With diagnosed sleep apnoea, the treating physician checks whether the appliance improves breathing during sleep sufficiently.
Care and limits
Clean the appliance daily with a soft brush and cool water, and store it dry. At the regular check-ups we examine the fit, the material and the response of the jaw joint. It is important to see the limits realistically: the appliance keeps the airway open for as long as it is worn, but it removes neither excess weight nor other causes.
When medical help is needed
Seek medical advice if someone describes breathing pauses during your sleep, if you are very tired during the day despite enough hours of sleep, or if morning headaches and restless sleep persist. This should be assessed by sleep medicine. If you are unsure whether a snoring appliance is an option for you, book an appointment. We discuss your situation and coordinate the next steps with the medical diagnosis.
