Otago University and United Kingdom researchers developed the world-first device, which uses magnets to lock the mouth almost shut, to help fight the global obesity epidemic.
DentalSlim Diet Control is an intra-oral device fitted by a dental professional to the upper and lower back teeth.
The device was being widely ridiculed after being shared on social media, with Twitter users calling it "creepy" and "bizarre".
But Dunedin researchers who developed the device are defending the invention, saying those panning the weight loss tool have misunderstood its intention.
Lead researcher Prof Paul Brunton said it was not intended to be used for general weight loss purposes, but instead for specific cases where there was a clinical need to lose weight quickly.
