In recent years the Tongue Stabilizing Device (TSD) has become a popular treatment option for both snoring and obstructive sleep apnea (OSA). For years the Mandibular Advancement Device (MAD) has been the most popular choice in oral appliance therapy but today TSD’s are rapidly capturing an increasing percentage of the market share.

What exactly are TSD’s? These devices attach to the tip of one’s tongue via suction and rest either on the outside of the lips (recommended) or between the lips and the teeth. They are designed to hold the tongue in the forward position, preventing it from falling to the back of one’s throat. They also pull several muscles in and around the airway tight in order to help widen the airway. Here’s a more in-depth explanation of how TSD’s work.

In comparison, the Mandibular Advancement Device or MAD fits in between the upper and lower teeth. It resembles a mouthpiece used for teeth grinding or a sports guard. This type of device uses leverage action to hold the lower jaw forward. Like the TSD, the MAD also tightens muscles and helps to widen the airway, thereby eliminating snoring.

If you currently use a MAD and have become accustomed to wearing a one, it may take a few days to adjust to a TSD. Most who use this type of anti-snoring device experience some tongue soreness during the initial 3 to 5 days of use. Once adjusted, they are fairly comfortable to wear on a nightly basis.

There are currently two major players in the TSD industry РThe Good Morning Snore Solution and the AveoTSD. The GMSS was created by Dr. Leslie Dort, a Canadian dentist while the AveoTSD was invented by New Zealand dental sleep medicine specialist Dr. Chris Robertson. Both devices have been clinically proven to effectively treat snoring and mild sleep apnea in some cases.

AveoTSD and Good Morning Snore Solutions similarities and differences


  • Both the GMSS and the AveoTSD are made from a safe silicone material that is quite flexible and soft. Being soft and flexible makes it easy on the gums and comfortable to wear.
  • Both devices have been clinically tested and are equally effective at treating snoring.
  • Both are compact and lightweight allowing for easy handling and storage.
  • Both allow you to effectively control snoring without taking up a lot of room in the mouth.
  • Both have a life expectancy of 12 months or greater.
  • Both are easily cleaned using denture cleaning tablets which can be purchased at any pharmacy.
  • Both devices are a one size fits all solution to snoring and do not require any sort of fitting process. Simply squeeze the tip and allow the suction to draw your tongue into the bulb.


  • The AveoTSD offers a longer sleeve to hold the tongue whereas the GMSS features a shorter sleeve.
  • GMSS tongue suction bulb is slightly smaller and more narrow in comparison to the AveoTSD.
  • The tongue retaining tabs are positioned vertically with the AveoTSD while the GMSS retaining tabs are positioned horizontally.
  • Materials are of different thicknesses. The GMSS is constructed of a thinner silicone material in comparison to the thicker material of the Aveo.
  • The GMSS offers a risk-free 30-day money back guarantee while the AveoTSD does not.
  • The Aveo sells for approximately $140 while the GMSS sells for around $100.

Which one should I choose?

There is no denying that both devices can be a great choice when it comes to controlling the sounds associated with snoring. Both have received numerous praises from snoring suffers from around the world. So which one is better? How do you decide which one to purchase?

Overall, the two are very similar in nature and are even constructed from the same material. They both perform the same function, are comfortable to wear and easy to clean. Making a decision can be difficult when you are comparing two very similar products side by side.

The first thing to consider is availability. In some instances, one may find it difficult to locate a distributor who will ship these products to their particular country. While there are a number of reasons why this can be a challenge, the most common reason has to do with law restrictions from one country to another. In the United States, Canada, and the UK you should not have an issue ordering either device.

Personally, I’ve tried both the GMSS and AveoTSD and found both to be equally comfortable and effective. While not affecting comfort, the Aveo was however noticeably thicker in comparison to the GMSS.

In the end, the real difference comes down to the price and guarantee. The GMSS sells for $40 less than it’s opponent and comes with a money back guarantee. Because of these two reasons I favor the GMSS.

A note about treating sleep apnea

Keep in mind that self-treating sleep apnea using an internet ordered TSD is not advisable. Such devices are intended to treat benign snoring or simple snoring. If you are interested in treating a medical condition such as OSA with a mouthpiece, be sure to first speak with your doctor to seek their professional medical opinion. Remember, sleep apnea can lead to serious medical conditions such as high blood pressure and stroke.
