The Canadian Agency for Drugs and Technologies in Health (CADTH) has looked at the evidence available to address the question: What is the evidence that weight loss can affect the fit or stability of dentures?
They searched PubMed, the Cochrane Library, University of York Centre for Reviews and Dissemination (CRD) databases, ECRI, EuroScan and the international health technology agencies. The search covered the years 1999-2009 and was limited to studies in the English language.
They found no literature relating to evidence that weight loss can effect the fit or stability of dentures.
CADTH is an independent, not-for-profit agency that delivers timely, evidence-based information to health care leaders about the effectiveness and efficiency of health technologies. It is funded by Canada’s federal, provincial, and territorial governments.

does losing weight effect how dentures fit , I have lost weight, and my dentures are very lose , do your gums shrink with weight loss
As review above noted they could not find any scientific evidence to link weight loss with ill fitting dentures. Most dentures become progressively looser over time as the ridge of the jaw bone on which they sit shrinks in time.
I think they are wrong I too have recently lost weight and my dentures are not fitting well.
