Willingness to pay and its determinants for missing tooth replacement among older adults: A cross-sectional study in Japan

While the absence of depressive symptoms emerged as the strongest predictor of whether individuals expressed WTP to replace missing teeth among older adults, wealth emerged as the most influential factor in determining the amount they were willing to pay for both anterior and posterior teeth. WTP is largely explained by economic, psychological, and social factors. These findings suggest that promoting oral health may require integrated strategies addressing financial barriers, mental health support, and social engagement.
