What common condition can lead to difficulty in wearing complete dentures?

Sjögren's Syndrome is an autoimmune condition that primarily affects the body's moisture-producing glands, leading to dry mouth (xerostomia) and dry eyes, among other symptoms. The reduction in saliva due to this syndrome can significantly impact the ability to wear complete dentures comfortably. Saliva plays a crucial role in creating the suction that helps keep dentures in place, and without sufficient saliva, individuals may experience difficulties such as poor retention, discomfort, and the potential for increased irritation or ulcers in the mouth.

In comparison, while gingivitis, tooth decay, and periodontitis can cause oral health issues, they are not primarily associated with the challenges of wearing dentures related to moisture levels. Gingivitis and periodontitis involve gum inflammation and periodontal disease, which primarily affect the supporting structures of natural teeth rather than the fit of dentures. Tooth decay affects individual teeth but does not directly correlate with the challenges encountered in wearing complete dentures. Thus, Sjögren's Syndrome stands out as the condition most closely linked to issues with denture wear due to its direct effect on saliva production and oral moisture.
