About Us

Who We Are

The dental facility was founded in 1979 and follows the same tradition of quality health care, reasonable prices, same-day-service and Ozark hospitality as first established by Drs. Harold E. George and Frederick C. Lauer as the Mid-America Denture Clinic. Dr. Jay Hildreth established Dental Centers' practice in 1995 and purchased Mid-America Dental Clinic in 1997.

Dental Centers with two locations in Mt. Vernon, Missouri at Mid-America Dental & Hearing Center-Highway and Mid-America Dental & Hearing Center-Loop is the Ozark pioneer of the custom, same-day, denture. Today, Dental Centers offers many other non-specialty interest services, including general dentistry with a new family dentistry emphasis, hygiene, crowns, bridges, orthodontics and implants.

A visit to Mid-America is a long-standing tradition for some families. There is free RV parking in the Mt.
