You don’t usually see hundreds of people excitedly rush to their dentist’s office. But nearly 700 people visited the BGW Dental Group on Thursday evening for an open house celebration at the practice’s new facility in Gainesville. The facility at 1215 Vine St. combines the practice’s two former locations into one complete with 16 patient rooms, four private consultation rooms, two surgical suites, two private recovery areas, two sterilization labs and more.
