About Dr. Harold Katz

Dr. Harold Katz is the founder of The California Breath Clinics and the developer of the TheraBreath line of oral care products. He is an internationally recognized expert in the fields of bad breath, taste disorders, tonsil stones, and dry mouth. Known as the 'Bad Breath Guru' due to his numerous television appearances, he has helped millions of people around the world.

 

Dr. Harold Katz graduated from the University of California, Los Angeles (UCLA) with degrees in Dentistry and Bacteriology. Dr. Katz began his breakthrough research into the causes of bad breath in the early 1990s after he was unable to help his teenage daughter with her bad breath. Despite brushing and flossing several times a day, her bad breath problem persisted. Dr. Katz's background in bacteriology soon helped him to realize that bad breath can be caused by a group of sulphur-producing bacteria that live and multiply within the tongue's surface and in the throat.

 

Armed with this newly discovered knowledge, Dr. Katz began to experiment with formulas that would reduce the sulphur-producing bacteria that cause bad breath. And so the TheraBreath product range was born.
