The California Dental Association (CDA) is a community of dentists committed to enhancing the professional lives of our members—27,000 of the best and brightest in dentistry. Together, we champion better oral health care for all Californians. Since a small group of dentists founded CDA nearly 150 years ago, we’ve grown to become the single largest membership in the American Dental Association and a constant trusted resource for California dentists and their patients. CDA supports dentists in all stages of their careers through dedicated resources, including education, practice support, advocacy and protection.
