Dr. Harold Katz, founder of The California Breath Clinics,
is the recognized expert in the fields of bad breath, tonsil stones, and dry
mouth. Known as the 'Bad Breath Guru' from 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 UCLA and 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 techniques while working with some of Hollywood's biggest rising stars.
Dr. Katz began his own breakthrough research into the causes of Bad Breath in
the early 1990s, after he was unable to help his own teenage daughter with her
severe and chronic breath problem. Highly advertised commercial mouthwashes were
making her breath more offensive, and despite immaculate oral hygiene (brushing
5-6 times daily with the most popular toothpastes & flossing several times a
day), the problem persisted. His background in Bacteriology assisted him in
realizing that Bad Breath is caused by a group of Anaerobic Sulfur-Producing
Bacteria which breed WITHIN the tongue's surface and throat. Under certain
conditions, these bacteria initiate the production of the Volatile Sulfur
Compounds found in Bad Breath and Taste Disorders. Bad Breath DOES NOT come from
the digestive system, as some highly advertised products falsely
Armed with this knowledge, Dr. Katz began to experiment with new formulas that would attack the Anaerobic Sulfur-Producing Bacteria within the mouth. In 1993 he founded the internationally acclaimed California Breath Clinics, where he treated and continued to study patients with chronic breath problems, tonsil stones, and other troublesome oral care issues that did not have simple, effective over the counter treatments. The resulting products - refined over and over since their introduction - are nothing short of astonishing. Clinical tests of Dr. Katzs' patients have repeatedly resulted in a complete elimination of over 98% of the Volatile Sulfur Compounds that cause bad breath within the mouth.
In 2002, Dr. Katz published his breakthrough Bad Breath
Bible, the definitive guide to the causes and cures of most bad breath
and unpleasant mouth taste problems. The guide has gone on to dozens of
re-prints and is now in it's second edition, with over 1,000,000 copies in
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 in the US and internationally, and over ONE MILLION PEOPLE worldwide have used his TheraBreath System formulas to eliminate Halitosis and regain their lost confidence.
