Dental Health Research: Glendale and Los Angeles County
Plain-language looks at public data on dental health where our patients live: how many people see a dentist, how many have lost their teeth, what is in Glendale's tap water, how often people end up in the ER for tooth problems, and how Medi-Cal members use their dental benefits. Every figure names its source and the period it covers, and the data behind each page is free to download.

We only use public data from government agencies. Scripts download the source files, compute every figure and check the headline numbers a second time against a different table or file before a page goes up. Population data only: these pages describe communities, not anyone's health, and they are not medical advice.
Journalists, researchers and neighbors are welcome to reuse the data. Each page has a CSV download under a Creative Commons Attribution 4.0 license; please link back to the page you used.
