Dr. Katz is the founder of the California Bad Breath Treatment Center in the United States, and he has successfully helped tens of thousands of people overcome their bad breath problems through his TV channel, and is known as the "bad breath buster" in the United States. Dr. Case began his career as a medical formula to remove anaerobic bacteria that cause bad breath, and later specialized in oral hygiene products, which consistently ranked first on Amazon in the U.S. and had the highest brand recognition of any product of its kind.
 
Dr. Case Breath Freshener is only available in one universal form, with a unique OXYD-8 oxygenating formula that destroys the breeding conditions for anaerobic bacteria and inhibits the source of bad breath for a longer lasting effect than conventional practices by masking the taste. In addition to containing OXYD-8 oxygenation technology, its main ingredient is zinc gluconate, which is added to the breath freshener to help eliminate bad breath and delay the accumulation of dental calculus. Although zinc is not the best choice for bad breath removal, it is safe, does not cause tooth staining, and can be used for a long time.

Dr. Case Breath Freshener uses a catheter-type bottle mouth design on the packaging, which needs to prevent leakage when used, and the price of 30ml is 55 yuan.
