    Silent Treatment Tongue Training Device Review

    Updated March 2026·By George Sanders·Medically reviewed content

    Need is truly the mother of invention. It is when spouses Shelley Rowarth and Michael Rowarth, both the co-inventors, could not sleep because of the intense snoring of the latter. Michael, a professional toolmaker with all-embracing involvement in product design, worked hard to address the issue of how to stop snoring.

    He also engaged in using a variety of anti-snoring equipment available on the market. None of them worked as he wanted, so Rowarth Design Limited was born.

    Tongue Restraining Device (TRD), the principle of the Silent Treatment, can aid people who snore, as well as those suffering from sleep apnea. They are cost-efficient and less burdensome as compared to CPAP machines. TRDs work by clipping the tongue forward during sleeping time. This position maintains the tongue from blocking the air passage.

    The Silent Treatment

    Silent Treatment is a boil-and-bite type of apparatus. It does not exert force for the lower jaw to be forward as this can put an intense strain on the jaw.

    The Silent Treatment is held fixed by an impression only of the side teeth. Its tongue pad presses on the upper surface making the teeth keep in place. The tongue pad is wrapped with tiny spurs, tailored to connect with the papillae on the tongue, akin to Velcro. The tongue is thus kept in place.

    One added advantage of Silent Treatment is its dependence on muscle memory. It acts as a guide for tongue muscle. The muscle then remembers the position it's been kept to adopt in times of sleep, and after a short period of time, you will only utilise it once every week to aid in retaining muscle memory.

    The prototype of the Silent Treatment is extraordinary. It utilises the impression of the teeth as a crucial role in the design but does not force the jaw into another place. It is trademark-protected internationally, and a patent application is on its way.

    Be that as it may, it is not guaranteed that it can work for everyone. If the tongue is not the primary issue on the person's snoring and apnea disorder, or if their mouth is small, the Silent Treatment will not meet your expectation. However, they guarantee a full refund on the product.

    Fitting and Adjustment

    The manuals and guides are crystal clear. You have to ensure that the Silent Treatment is correctly in place with your mouth during the custom mould. It is recommended to utilise a mirror to lead your position.

    During the device fitting, bring water to a boil and boil it for about sixty seconds. After that, the Silent Treatment is ready for moulding after it comes out of the boiling water.

    In general, an adjustment would cost you about 3-4 days. The initial night is crucial; you will surely have a hard time swallowing while it is intact. There would be saliva build-up. But the Silent Treatment holds the tongue resolutely. In the second and succeeding nights, you will slowly get used to it.

    Conclusion

    Silent Treatment will be efficient for the right individuals. The right people will surely have the patience and time to get used to it while practising. The adjustment period makes it a bit complex to get helpful reviews of its efficiency.

    The device is not approved by FDA because it is made in New Zealand. Though the company is trustworthy and based on reviews, all transactions are honest and worry-free.

    While it is true that this product can be an efficient product at times, it is not for all people. It is best recommended for better efficiency to utilise AirSnore's excellent solution as compared to the Silent Treatment because the mouthpiece in AirSnore moulds itself and is a bit elastic with very soft bristles that will not give any uneasy feeling to users.
