What’s The Difference Between a MAD and TSD Mouthpiece

What Is a MAD and TSD And Which One Should You Choose

The first thing to clarify is the fact they are both snoring mouthpieces. They just work to stop snoring in two entirely different ways…..but they both work.

It is important you understand the difference between the two types because not everyone can use a MAD [Mandibular Advancement Device] or TSD [Tongue Stabilizing Device]. You could waste lots of money and damage your teeth if you order the wrong one.

I can certainly take the confusion away for you in this article so you will know exactly what will suit you and what won’t.

Madibular Advancement Device [MAD]

The vast majority of stop snoring mouthpieces manufactured today are mandibular advancement devices. That’s not to say they are the best but simply the more traditional style.

These are a couple of examples

The MAD mouthpieces work to stop snoring by surrounding the teeth of both the upper and lower rows and moving the lower jaw in a forward advancement.

The lower jaw is know as the mandibular and the effect of moving it forward opens up the air passage in the rear of the throat. This in turn also helps to move the tongue forward allowing air to flow more freely when you sleep and stop the vibrations at the rear of the throat which we more commonly know as snoring.

 Tongue Stabilizing Device [TSD]

Whilst these types of stop snoring devices are not manufactured in large numbers they are still worthy of consideration and at times the only choice for many people.

My wife for example is best suited to this type of device and it works perfectly well for her…and of course me because I don’t hear her snoring all night.

Some Examples

The TSD works by pulling then holding the tongue forward and away from the rear of the throat. This opens up the air passage avoiding the snoring vibrations caused by the narrowing.

The tongue is inserted into the bulb at the front of the mouthpiece and a sucking and slight pressure force is applied to the bulb which in turn holds the tongue comfortably in place.

It does not move the mandibular forward in the same way as the MAD mouthpieces and as a result applies little to no pressure to the teeth or jaw whilst in use.  Many people have found these devices to be more comfortable than most of the MAD mouthpieces.


Which One Suits You Best – What One Not To Use

Mandibular Advancement Devices

Who Should NOT Use

1. The manufactures will tell you NOT to use one of their devices if you have any type of denture, crowns, bridges or have loose teeth. They do have the potential of damaging dental work or loose teeth due to pressure placed on the teeth when in use.


Some people have used them if they have minor dental work at the rear of the mouth, as it is generally the front teeth that come under the most pressure. I am not recommending this course of action…just providing feedback.

2. The manufacture will also tell you NOT to use them for the sole purpose of addressing Sleep Apnea issues.


I have also obtained feedback from some people that have Sleep Apnea who have used them in combination with traditional forms of OSA treatment or as a brief substitute from time to time eg: weekends away on holiday, sleepovers etc. Again I make NO RECOMMENDATIONS, this is just feedback. Please consult you family Doctor before considering this option.

3. If you have any form of Temporomandibular Joint Disorders [ TMJ] then you should NOT use these types of stop snoring mouthpieces.

4. Children should avoid these devices. Their bone structure is still developing.

Who CAN Use

1. Anyone who does not fit into the above should feel confident to try.


Tongue Stabilizing Devices

Who Should NOT Use

1. People with Deviated Septum – a blockage in the nose which restricts airflow through the nose. When you use a TSD you draw the majority of your air through your nose. Depending on the severity of a deviated septum, a person could find it difficult to breath when sleeping. In actual fact my wife still manages to use this type of mouthpiece when she has a mild head cold and blocked nose. She seems to be able to draw sufficient air in through the mouth around the sides of the mouthpiece.

2. Same issues for people with Sleep Apnea as detailed in point 2 above. Maybe a part time application at best.

Who CAN Use

Anyone else can use a TSD other than children. They are growing and their bodies are still developing.

There is no pressure applied to teeth, jaws or gums. They are arguably much more comfortable to use than the traditional MAD mouthpieces and some last longer.

If you don’t have dental or OSA issues it will just be a personal choice.

I use the SnoreMD, relatively new Mandibular Advancement Device however my wife uses the Good Morning Snore Solution, an innovative Tongue Stabilizing Device because she has dental work to contend with. I have tried a number of other MAD devices plus the GMSS TSD but I prefer the SnoreMD.

Conversely my wife had limited options and tried the GMSS first and it was perfect for her.
