A weight loss device that is fitted to teeth to stop the mouth from opening has been designed in a bid to fight obesity.

The tool was developed by medical professionals from the University of Otago in New Zealand. The research team said it created the tool in a bid to fight the obesity on a global scale.

Called the Dentalslim Diet Control, it is fitted by dentists and uses magnets – as well as locking bolts – to prevent people opening their mouths.

Once fitted, users can only open their mouths 2mm wide.

Low-calorie liquid diets

The University of Otago tweeted: ‘Otago and UK researchers have developed a world-first weight-loss device to help fight the global obesity epidemic. An intraoral device that restricts a person to a liquid diet.’

The device was tested on seven obese women for two weeks. They were given a low-calorie liquid diet during this time.

Published in the British Dental Journal, findings revealed the participants lost a mean amount of 6.36kg, amounting to just over 5% of their body weight.

However some of the woman reported feelings of discomfort and trouble speaking. Another admitting to consuming foods, such as chocolate, by melting them down.

Not a quick fix

Speaking about the device, Professor Paul Brunton described the main barrier to successful weight loss is ‘compliance’.

‘This [device] helps them establish new habits, allowing them to comply with a low-calorie diet for a period of time,’ he said.

‘It really kick-starts the process. It is a non-invasive, reversible, economical and attractive alternative to surgical procedures.

‘The fact is, there are no adverse consequences with this device.’

However researchers insisted the device is not intended as a long-term solution.

‘To clarify, the intention of the device is not intended as a quick or long-term weight-loss tool; rather it is aimed to assist people who need to undergo surgery and who cannot have the surgery until they have lost weight,’ a follow-up tweet from the university read.
