Dr. Mark Cohen, the LA Gum Doctor, received his advanced training in Periodontics & Dental Implants at the University of California, Los Angeles, during an era where biology and technology converged and an exciting new Periodontal profession was born. In this era, dental implants, Biologics (healing proteins), which grow new healthy gum and bone, and dental lasers which eliminate Periodontal (gum) disease in a minimally invasive procedure were developed and flourished.
