The Chicago Dental Society is an association for dentists in the metropolitan Chicago area (Cook, DuPage and Lake counties). We organize the annual Midwinter Meeting – the leading scientific dental meeting and tradeshow. CDS promotes the art and science of dentistry and improving oral health for all. CDS members have been keeping Chicago smiling for 150 years. Since our founding in 1864, and incorporation in 1878, our mission has been to encourage the improvement of the health of the public, to promote the art and science of dentistry and to represent the interest of the members of the profession and the public that it serves. We count more than 6,100 dentists as members.
