Praised for its ability to attack and eliminate embarrassing breath odour, the patented TheraBreath formula in Fresh Breath Rainforest Oral Rinse uses the power of oxygen to target bad-breath-causing bacteria deep below the surface of the tongue and at the back of the throat. This refreshing, alcohol-free antibacterial cleanser rinse doesn't burn or sting, so its easy to use every day. TheraBreath Rainforest Oral Rinse is certified kosher, gluten-free and vegan. It is also free of dyes, perfumes, detergents, and other harsh additives that can dry or damage the mouth. TheraBreath Fresh Breath Oral Rinse is our flagship product and has been dentist- and pharmacist-recommended for more than 20 years. TheraBreath Fresh Breath Oral Rinse is an ADA approved product and has become one of the United States' best-selling speciality oral hygiene treatments. Fresh Breath Oral Rinse by Dr. Katz attacks sulphur-producing bacteria, morning breath, and food odour. In fact, clinical studies have verified that TheraBreath is extremely effective at attacking bad breath odour for up to 24 hours. This powerful mouthwash eliminates even the most severe cases of bad breath or halitosis (which is the scientific name for this condition). Dr. Katzs proven oral rinse formula does not contain alcohol, artificial flavours, or colours. It is also pH-balanced to maintain a non-acidic environment in the mouth, which reduces burning and enamel erosion, while preventing tooth sensitivity. This product is safe to use twice daily and is available without a prescription.
