“What’s Behind Her Smile? Health, Looks, and Self-Esteem”, Francisco A. Gallego, Cristian Larroulet Philippi, Andrea Repetto2024-04 (, )⁠:

This paper examines how improving dental health affects economic, social, and psychological outcomes. In a randomized experiment, we provide a low-income group free dental care, including prostheses, and find:

statistically-significant and persistent impacts on men’s and women’s dental and self-perceived mental health.

For women, treatment generates improvement in self-esteem, a higher likelihood of smiling when photographed, short-run improvements in employment and earnings, and improvement in partner interactions. Heterogeneity analyses suggest that treatment effects on labor market outcomes are larger for women with more severe visible dental issues at baseline.

We find no impact for men in these dimensions.
