What the research shows
What we read, what it says and what it doesn’t. We name our sources, quote them carefully, and say where the evidence stops.
What we rely on.
Three public sources carry most of this page.
Why people snore.
The NHS puts it simply: snoring is caused by things such as your tongue, mouth, throat or the airways in your nose vibrating as you breathe, and these parts relax and narrow when you are asleep. [5]
What makes it more likely
- Being overweight
- Smoking
- Drinking too much alcohol
- Sleeping on your back
- Blocked or narrow airways in the nose
- The tongue partly blocking the throat
- The mouth falling open during sleep

What people try first
The NHS suggests losing weight if you are overweight, sleeping on your side, and avoiding smoking, heavy drinking and sleeping pills. It also mentions that partners can use earplugs. [5]
When to see a doctor
See a doctor if lifestyle changes aren’t working, if snoring affects your quality of life, or if you notice daytime sleepiness, pauses in breathing or gasping during sleep. [5]
It is aimed at one cause: the jaw and tongue drifting back. It does not change the others. That is why we say snoring has more than one cause.
In one sleep-center study, women snored more than they said.
The study looked at 1,913 patients, average age 49, referred to a sleep disorders center at a university hospital. Snoring volume was measured with a calibrated digital sound meter during a full-night sleep study, and patients also rated their own snoring on questionnaires. [1] [6]
Snoring measured in a sleep study, and snoring people said they had
Women (675)
Men
Severe or very severe snoring, women
Average maximum snoring intensity, in decibels
What the principal investigator said
“We found that although no difference in snoring intensity was found between genders, women tend to underreport the fact that they snore and to underestimate the loudness of their snoring,” said Nimrod Maimon, MD, MHA, of Ben-Gurion University of the Negev. According to the authors, there is a social stigma associated with snoring among women. [6]
Why it matters here
It is why we speak plainly about this. Nobody is failing at anything by snoring, and hiding it is common.
These patients had been referred to a sleep center, so this doesn’t mean 88% of all women snore. It shows how often women in this group underreported it. The study is about snoring, not about any product.
The 2015 guideline, and what it doesn’t say.
In 2015, the American Academy of Sleep Medicine and the American Academy of Dental Sleep Medicine issued a joint guideline. A task force of three sleep physicians and two dentists reviewed 51 articles. [2] [7]
What it recommends
That sleep physicians prescribe oral appliances, rather than no therapy, for adults who request treatment of primary snoring: snoring without a more serious breathing problem in sleep. [7]
What it also says
For adults with sleep apnea, the guideline suggests that a qualified dentist use a custom, titratable appliance rather than a non-custom device, and that dentists follow up to watch for changes in the teeth and bite. [7]
What that means for Silentrin
The guideline describes oral appliances as a category, usually made by a dentist and prescribed after a diagnosis. Silentrin is not that pathway. It is molded at home, in one size, adjusted by you, with no dentist follow-up built in.
That is why we tell you to get an oral health check before you start, to stop and see your dentist if something changes, and to see a doctor if snoring comes with gasping or heavy daytime sleepiness. It is also why we describe Silentrin as the jaw-forward principle applied at home, not as a replacement for a dentist’s care.
Myths, and what we know.
Myth. Snoring is a men’s problem.
What we know. In the 2019 study, women snored about as loudly as men (50 dB and 51.7 dB), and 88% of the women were measured snoring. Women were more likely to say they don’t. [1]
Myth. Nasal strips, tape and pillows all do the same thing.
What we know. They act on different targets: the nose, the lips and the angle of your head. A jaw-forward mouthguard acts on the position of the lower jaw.
Myth. A mouthguard forces your jaw forward.
What we know. Silentrin starts at neutral. You move forward one small step at a time, the same mark on both sides, and you move halfway back toward neutral if your jaw or teeth are sore.
Myth. Only a dentist-made device is worth trying.
What we know. For adults with sleep apnea, the 2015 guideline suggests that a dentist use a custom, titratable appliance rather than a non-custom “boil and bite” device. For snoring alone, the guideline does not compare the two, and a 2020 review by the authors of the German guideline found that a direct comparison of custom-made and thermoplastic devices in isolated snoring had not been done. [8] Silentrin is not custom-made. It is a home test of the principle, with 60 nights to decide. See above
Myth. If you snore, it’s your nose or your weight.
What we know. Those are causes, and so is the jaw and tongue drifting back, alcohol, back sleeping and more. Snoring has more than one cause. [5]
Myth. One size means it won’t fit me.
What we know. Molding shapes the lining to your own teeth, but every mouth is different and it may not fit everyone. If it doesn’t fit you, the 60-night guarantee applies.
What it costs, and what insurance covers.
A dentist-made device typically starts around $1,500. The Hush is $49.99.
Typical cost of a device, in dollars
A dentist-made appliance is made from impressions of your teeth and adjusted by a professional. Silentrin is a different device: it applies the same jaw-forward principle at home, molded and adjusted by you, with 60 nights to decide.
Where the evidence stops.
The research above is about the jaw-forward principle, mostly in dentist-made devices. Here is what it does not cover.
- We have not tested Silentrin in a clinical study. What we describe is how it is designed to work.
- It may not stay in all night or work for every sleeper: every mouth is different.
- Long-term data on wearing it every night for months or years is not available. Watch for changes in your bite and see your dentist.
- It comes in one size and may not fit everyone. If it doesn’t fit you, the 60-night guarantee applies.
- Snoring has more than one cause. A jaw-forward mouthguard is not the answer to all of them.
Glossary.
- Oral appliance
- A device worn in the mouth during sleep. Dentist-made ones are custom. Silentrin is one you mold yourself.
- Mandibular advancement
- Holding the lower jaw (the mandible) slightly forward. Devices that do this are often called mandibular advancement devices.
- Titratable
- Adjustable in small steps. Silentrin’s key moves the lower tray one step at a time.
- Neutral
- The starting position of the lower tray, with no forward push. You start here.
- Boil-and-bite
- A material softened in hot water, then shaped by biting into it. That is how Silentrin takes the shape of your teeth.
- Primary snoring
- Snoring without a more serious breathing problem during sleep. The 2015 guideline uses this term.
- Sleep study
- An overnight test in a sleep center that records breathing, sleep and sound. In the 2019 study, snoring volume was measured this way.
- Airway
- The passage air travels through, from the nose and mouth to the lungs. It can narrow behind the tongue during sleep.
