John Cosby

Dr. John Cosby, DMD

General Dentistry



Dr. Cosby graduated with a Doctor of Dental Medicine degree from Washington University, St. Louis, Missouri in 1972. Following graduation, he entered the United States Navy and was commissioned a Lieutenant in the naval dental corps. He completed a U. S. Navy General Practice residency at Portsmouth Naval Hospital, Portsmouth, Virginia and was then assigned a staff position at the U. S. Naval Hospital at Roosevelt Roads, PR., attaining the rank of Lieutenant Commander in 1975. His experience and training in the Navy gave him the skills and experience to perform many dental procedures outside the scope of a typical general dentist, skills that he still uses today. In 1976, he established his general dentistry practice, Northeast Dental Associates, in his home town of Columbia, SC. His practice includes general and cosmetic dentistry, endodontics, oral and periodontal surgery, and comprehensive fixed and removable prosthodontics. In 1993, he was elected to the South Carolina Board of Dentistry and served the Board thru 1999 when he was elected President of the Board. Through this experience, he developed a passion for public protection and advocacy. He became involved with many other organizations that lead to numerous leadership positions, especially in the area of dental licensure testing. (To see a full list of Dr. Cosby’s achievements, please click here) In 2004 Dr. Cosby opened his second private practice, Blythewood Village Dental Associates. Dr. Cosby enjoys providing his patients with optimum, comprehensive dental care in his modern “state of the art” dental facilities. Dr. Cosby is married to his wife, Carolyn, and has two daughters, Mrs. Sarah Salters (Jeff) and Mrs. Lauren Ditzler (Rusty) and five grandchildren. In his free time, he loves to fish, travel, play golf, and spend quality time with his family and grandsons.

"Dr Cosby did a full-mouth dental restoration for me in 1996. I am now 85 and still enjoying the benefits of his work. I have had very few problems, even though the work is now 27 years old. Thanks for the ability to still eat most anything I want. "

Data Transparency and Trust: Understanding WebMD Doctor Listings and Reviews

We know that finding the right doctor or provider is important to your health. That’s why we want to ensure you have confidence in the provider profiles and listings you see on WebMD Care. Our provider data is sourced from the physicians themselves as well as publicly available databases. Any doctor or provider who claims their profile by verifying themselves can update their information and provide additional data on their specialties, education, accepted insurances, conditions they treat, and procedures they perform.

All the physician and provider reviews on WebMD Care are provided by users just like you. Knowing these reviews provide insight into how other patients feel about a doctor, we maintain internal policies and protocols to ensure the quality and accuracy of all reviews. Providers are not able to remove or modify reviews on their own. Reviews can only be removed after an internal review by our customer service team.

We value your input and encourage you to reach out to our support team if you encounter any issues.
