Original Activated Breath Rinse uses Smart-Zinc™ Technology to target the root cause of bad breath. The dual-solution system activates on use, stopping odour-causing bacteria and keeping the mouth fresh for a full 24 hours with just two rinses a day. Developed by Dr Marvin Cohen, a dentist recognised for his expertise in halitosis research, this rinse reflects years of clinical insight into oral malodour.

The formula works instantly to eliminate unpleasant odour and helps maintain a clean, fresh mouth overnight, so you wake up without morning breath. Recommended by dental professionals, Original Activated Breath Rinse offers a science-led approach to long-lasting breath freshness.

SmartMouth™ uses patented zinc ion technology that activates the moment you mix Solution 1 and Solution 2. This reaction creates billions of zinc ions that neutralise the sulfur gases responsible for bad breath, which is important because those gases come directly from bacterial activity in the mouth. By targeting the source rather than masking the smell, the formula keeps your breath fresh through the day and night with consistent twice-daily use.

SmartMouth™ was founded in 1993 by Dr Marvin Cohen, a leading expert in the science of halitosis, who set out to create a lasting solution to bad breath. After years of research into the root causes of sulphur gas production, he developed SmartMouth’s patented zinc ion activated technology, designed to stop odour at its source. Each rinse uses this clinically tested system to keep breath fresh for hours while supporting everyday oral hygiene. Through this science-led approach, SmartMouth™ helps you feel confident, comfortable, and fresh every time you speak, smile, or start your day.
