Why We Never Use Plastic: The Cobalt Chrome Advantage

Most anti-snoring devices are made from thick plastics. Recent major scientific studies reveal that wearing plastic in the mouth night after night comes with hidden health risks. Here is why the Somnowell is uniquely crafted from surgical-grade Cobalt Chrome.

Zero Microplastic Shedding

The Problem: Nighttime jaw movement causes plastic splints to shed thousands of microscopic plastic particles.1 2 These swallowed microplastics have recently been found to cross biological barriers, triggering gut inflammation3 and correlating with higher cardiovascular risks.4

The Somnowell Solution: Cobalt Chrome is cast metal. It cannot splinter or shed, keeping your digestive and cardiovascular systems completely free of dental microplastics.

Superior Oral Hygiene

The Problem: Dental plastics have rough, porous surfaces that act as a breeding ground for harmful bacteria, leading to bad breath and gum irritation.5

The Somnowell Solution: Cobalt Chrome is non-porous and impervious to bacteria. It stays incredibly clean, protecting your oral microbiome.

No Toxic Chemical Leaching

The Problem: Plastic intraoral devices can expose the mouth to chemical remnants and unpolymerized monomers, causing localized tissue irritation. 6

The Somnowell Solution: Our medical-grade alloy is biocompatible, hypoallergenic, and completely free from all plastics, BPA, and chemical coatings.

“it is worth every penny”
- British former Rugby Player Jonathan Davies OBE

“Having tried and tested over the counter plastic devices, I realised that I needed a more comfortable and long term solution to my snoring issue. The Somnowell device is seamless and I can hardly notice that I am wearing it. My snoring has been eliminated and my wife and I now benefit from high-quality sleep! I would recommend this device to anyone who suffers from snoring - it is worth every penny. There are over 300 Somnowell Practitioners in the UK. I ordered my device through Dr Matthew White at The Whites Dental Centre, Cardiff.”

Mrs J. from Nottingham:

"Having snored very loudly and sounding like a pneumatic drill for many years, I have given my husband many a sleepless night... This custom made piece of metalwork is easy to tolerate and it works!".

Doctify Review:

"My jaw is slightly receding and bringing it forward stops my snoring. It has been a huge relief to my husband and it is also a lot less embarrassing not to be snoring when away from home. I would recommend it unreservedly.".

Doctify Review:

"The Somnowell is the only device that will stop a heavy snorer In their tracks, enabling me and my fiance a great nights sleep!".

“has certainly worked for me!”
- Michelle Norman as seen on Channel 5

“When I started my snoring journey I was using the snore lab app on my phone, this would record my snoring and give me accurate readings on how loud my snoring was. I peaked at 146 (the average person has a reading of 25) My reading is now 17 all thanks to the Somnowell Mandibular advancement device and a stone and a half weight loss. I wear it every night. I now sleep back in my own bed with Ken and I don’t snore. Its unbelievable. If your burdened with snoring I’d definitely recommend Somnowell. The Somnowell Chrome device has certainly worked for me!”

Sharon:

"I switched from the CPAP to the Somnowell device. I have Sleep Apnoea, which means I stop breathing in my sleep. I was using a CPAP machine which is a big, bulky, noisy thing ... then I discovered the Somnowell. It has changed my life.".

Mr B:

"Changed my life - was suffering from sleep apnoea with all the accompanying issues (tiredness, stress, mood swings) and the Somnowell device is like a magic wand that made the condition disappear.".

Richard:

"He suffered from Obstructive Sleep Apnoea (OSA). He didn't like using the Continuous Positive Airway Pressure Machine (CPAP)... The data shows a significant reduction in his snoring levels—dropping from an 'epic' score of 110 before using Somnowell to a much quieter/light level of 3 after using it.".

“from Pneumatic drill to dormouse”
- Mrs J. from Nottingham, England

“Having snored very loudly and sounding like a pneumatic drill for many years, I have given my husband many a sleepless night. I decided to invest in a somnowell device. I have had a bulky plastic device previously which was uncomfortable and just did not work. This custom made piece of metalwork is easy to tolerate and it works!
With these devices you get what you pay for and this, I believe, is well worth the investment.
I do occasionally snore just a little if I have had alcohol or am exceptionally tired- but absolutely nothing like the previous level of noise I made.
I was also concerned that the device might damage my veneers but this is not the case.”

Jonathan Davies OBE:

"Having tried and tested over the counter plastic devices, I realised that I needed a more comfortable and long term solution to my snoring issue. The Somnowell device is seamless and I can hardly notice that I am wearing it.".

Michelle Norman:

"When I started my snoring journey I was using the snore lab app on my phone... I peaked at 146... My reading is now 17 all thanks to the Somnowell... I now sleep back in my own bed with Ken and I don't snore. Its unbelievable.".

A Managing Director from Hampshire:

"14 years, over 4,000 nights - Somnowell has transformed my sleep and energy.".
