Dentist 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 the 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 on shows like The View and the CBS Early Show, he has helped millions of people around the world neutralize their bad breath.

Dr. Katz is a graduate of the UCLA School of Dentistry and holder of a separate degree in Bacteriology, also from UCLA. In the 1970s he established a thriving dental practice in Beverly Hills, California, minutes from bustling 20th Century Fox Studios.

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. Dr. Katz's background in bacteriology soon helped him to realize that bad breath did NOT come from the digestive system as some were claiming at that time. Instead, Dr. Katz discovered that bad breath is caused by a group of sulfur producing bacteria which live and multiply within the tongue's surface and in the throat.

Armed with this newly discovered knowledge, Dr. Katz began to experiment with oral rinse that would reduce the sulfur producing bacteria that cause bad breath. The resulting products were the beginning of the TheraBreath brand. In 1993 he founded the internationally acclaimed California Breath Clinics where he treated and studied patients with chronic bad breath, taste disorders, tonsil stones and dry mouth issues.
