Dr. Katz has been on countless televsion shows like the CBS Early Show, The View, and he’s helped millions of people around the globe get fresher breath. Some of his main areas of expertise are halitosis, dry mouth, and tonsil stones. He went on The Lionel Show on December 11, 2009 to talk about “The Horrors of Holiday Halitosis”. It’s definitely not a joking manner, especially if you’re standing under a mistletoe.
