Dr. Harold Katz

Dr. Harold Katz, creator of the TheraBreath systemDr. Harold Katz is the founder of The California Breath Clinics and the developer of the TheraBreath line of premium 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 eliminate their bad breath problems.

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. There, he perfected his dental techniques while working with some of Hollywood's biggest stars.

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 severe and chronic bad breath. Standard mouthwashes were making her breath more offensive and despite brushing and flossing several times a day, the problem persisted. Dr. Katz's background in bacteriology soon helped him to realize that bad breath did NOT come from the digestive system as some popular, highly advertised products 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 and toothpaste formulas that would destroy the sulfur producing bacteria that cause bad breath. The resulting products were the beginning of the TheraBreath System. 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. Clinical tests of Dr. Katz's patients, treated with TheraBreath, repeatedly resulted in a complete elimination of over 98% of the volatile sulfur compounds that cause bad breath.

In 2002, Dr. Katz published his breakthrough book, "The Bad Breath Bible", the definitive guide to the causes and cures of bad breath and taste disorders. It has proven to be wildly popular and is now in its second edition with over 1,000,000 copies in print and millions of downloads.

Since the introduction of TheraBreath products in 1994, no one has helped more people fight bad breath than Dr. Katz. Tens of thousands have been successfully treated through his California Breath Clinics and over 6 million people in 98 countries have used the TheraBreath System formulas to eliminate bad breath and halitosis and regain their lost confidence.
