Dental Cleanse contains Chlorhexidine Gluconate and Grapefruit Seed Extract - ingredients with antibacterial, antimicrobial, anti-inflammatory and antioxidant properties, effective in the elimination of the bacteria that cause bad breath and gingivitus. A drink of water treated with Dental Cleanse attacks this bacteria thus helping to prevent and heal gingivitus, remove plaque and tartar, and in turn, freshen breath. Using Dental Cleanse early in your pet's life provides for preventative oral care and excellent, long-term, dental hygiene. Using Dental Cleanse daily reduces the frequency and difficulty of professional cleanings. Dental Cleanse is safe for dogs and cats of any age.
