Who Discovered Periodontal Disease?
Glad you asked...
From what I know, Dr. Grace Rogers Spalding was the first dentist who specialized in periodontal disease. It is thought to be that Hesi-Re of Egypt was the first to discover periodontal disease. People have traced dentistry efforts back to prehistoric times.
