About Us

The BigMouth Project

The BigMouth Project is a significant collaborative initiative aimed at gathering and leveraging data from thousands or more individuals residing in the United States. Our primary objective is to enhance oral health outcomes through the collective data we gather.

Our mission is to expand the range of dental information available, enabling researchers to explore potential correlations among various health factors across different regions of the country. To support and advance dental research, we utilize specific data points.

By bringing together a diverse range of dental data, we strive to facilitate a deeper understanding of oral health and contribute to the overall improvement of dental research.

Explore the Dental Institutions Engaged in the BigMouth Project

Numerous dental institutions have enthusiastically joined the BigMouth initiative, contributing to the growth and enrichment of our existing database. These institutions actively input their own data, making it accessible to all BigMouth participants.
