Dallas County Dental Society (DCDS) has roots back to 1908 when it was a study club named the Dallas Dental Society. In 1915 the members voted to merge with another local study club called Dallas County Dental Society. The new organization retained the name of the larger Dallas County Dental Society and became the chartered local component society of the Texas Dental Association (TDA.) It is also known as the TDA 5th district component society within the Northeast Division.

DCDS is classified as a 501(c)6 not-for-profit corporation under the rules of the Internal Revenue Service.
