NOTICE: Temporary closure for non-emergency patients

Based on recommendations from the CDC, Missouri Dental Board, and St Charles County Health Department, we will be closing our office to non-emergency patients on 3/18/2020 until 4/1/2020. Dr. Blalock will be available for emergencies during that time. Please call the office at 636-441-7440 to leave an emergency voice message.

It has been recommended that people who are experiencing dental pain avoid crowding the hospital emergency rooms and urgent cares to make room for caring for patients experiencing coronavirus symptoms. Dr. Blalock will be available to the community for virtual visits for patients experiencing dental pain.

Emergency Virtual Visits can be made online and can be made 7 days a week.

The cost for a virtual visit is $29.
