Introduction Obesity is a global epidemic, increasing the risk of many associated health issues. Aim The aim of this clinical study was to investigate the acceptability and tolerability of an intraoral device, designed to facilitate weight loss. Method Seven healthy obese participants were recruited. The device, which incorporated closed-field magnets with keepers to restrict mouth opening, was cemented to the participants' first molars. The participants were given a commercially available liquid diet for two weeks. The comfort and tolerability of the device were assessed using a quality of life questionnaire during review appointments at 1, 7 and 14 days and two weeks after device removal. Results The participants reached a mean weight loss of 6.36 (SD = 3.79) kilograms, which represents approximately 5.1% of their body weight. The participants had trouble pronouncing some words and felt tense and embarrassed 'only occasionally'. The participants 'hardly ever' reported a change in taste sensation or felt uncomfortable drinking. However, participants indicated that they occasionally had discomfort and felt that life in general was less satisfying. Qualitative analysis showed that the participants were happy with the outcome and were motivated to lose more weight. Conclusion The participants tolerated the device for a two-week period with satisfactory weight loss and were further motivated to continue their weight loss journey.
