6 Anti-Snoring Myths Your Dentist Wants You to Stop Believing

Anti-snoring devices work brilliantly for many people, but a fair bit of confusion still surrounds them. Here are six myths dentists hear all the time, and what's actually true.

Myth 1: Any mouthpiece will do, so buy the cheapest one

It's tempting to grab the least expensive option online and hope for the best. The trouble is that snoring devices work by gently repositioning your jaw or tongue to keep your airway open, and how well that's achieved depends heavily on fit and design.

A device that's too loose won't hold your jaw in place through the night. One that's too tight can cause jaw ache or damage your teeth over time. Dentists tend to recommend spending time comparing options properly rather than choosing on price alone. Our guide to the best anti-snoring mouthpieces tested and compared looks at fit, comfort and build quality side by side, which makes the decision much easier.

Myth 2: A custom-fitted device is just an expensive version of a boil-and-bite

Boil-and-bite mouthpieces, the ones you soften in hot water and mould yourself, can work well for some people, especially as a starting point. But they're not the same thing as a device fitted by a dentist.

A dentist takes an impression of your mouth and creates a mouthguard shaped precisely to your teeth and jaw. This tends to feel more secure, distributes pressure more evenly, and can usually be adjusted in smaller increments as your jaw gets used to it. If snoring is a regular problem rather than an occasional nuisance, it's worth looking at dentist-recommended anti-snoring mouthpieces before settling on an off-the-shelf version.

Myth 3: If your jaw aches, the device must be working harder

Some discomfort in the first week or two is normal as your jaw and muscles adjust. But ongoing pain, clicking, or a bite that feels different in the morning are not signs of a device "working." They're signs it doesn't fit properly or has been adjusted too far, too fast.

Dentists advise stopping and getting the device checked if discomfort persists beyond the initial adjustment period. A well-fitted mandibular advancement device should feel snug, not painful, and you shouldn't wake with sore jaw joints or teeth.

What a properly fitted device should feel like

• Secure without pinching or digging in
• Comfortable enough to fall asleep in within a reasonable time
• No lasting soreness in your jaw or teeth the next morning
• A bite that feels normal once you remove it

Myth 4: An anti-snoring device means you don't need to see anyone about it

Buying a mouthpiece can feel like a simple, private fix, and often it is. But snoring devices are designed to reduce the noise and mild airway narrowing of ordinary snoring. They are not a treatment for sleep apnoea, and using one without a proper check can mean a more serious condition goes unnoticed.

It's worth seeing your GP before or alongside trying a device if you or your partner notice any of the following:

• Loud, frequent snoring accompanied by gasping or choking sounds
• Pauses in breathing during sleep
• Persistent daytime exhaustion, even after a full night's sleep

These can be signs of obstructive sleep apnoea, which needs proper diagnosis and, often, a different kind of treatment altogether. A dentist can still be involved in fitting a device, but usually alongside a diagnosis from a sleep specialist, not instead of one.

Myth 5: All snoring comes from the same place, so one device suits everyone

Snoring can be caused by a blocked nose, a collapsing tongue, a narrow throat, or a combination of these. A mandibular advancement device, which moves your lower jaw slightly forward, helps most when the tongue is the main culprit. It won't do much if your snoring is mostly down to nasal congestion or allergies.

This is one of the reasons dentists like to ask questions about your snoring pattern before recommending anything.

Myth 6: You should see results the very first night, or it isn't working

It's reasonable to hope for a quieter night straight away, but many people need a short adjustment period before a device feels comfortable enough to keep in overnight. Some also need small adjustments to the jaw advancement setting to find the right balance between effectiveness and comfort.

Give a new device a fair trial of a couple of weeks before deciding whether it's right for you. If it still feels wrong after that, it's better to have it reviewed or try a different design than to give up on the idea altogether. Our reviews hub is a good place to compare alternatives if your first choice hasn't worked out.

A sensible way forward

Anti-snoring devices can genuinely improve sleep for you and anyone sharing your bed, but they work best when you go in with realistic expectations and the right information. Choose a device suited to the actual cause of your snoring, expect a short adjustment period, and don't ignore ongoing discomfort.

Most importantly, if your snoring is loud and irregular, involves breathing pauses, or leaves you exhausted during the day, speak to your GP before relying on a mouthpiece alone. A quieter night's sleep is worth pursuing properly, not just quickly.
