Dental disease affects the majority of adult dogs and cats — estimates suggest over 70% of dogs and 80% of cats over the age of 3 have some degree of periodontal disease. Plaque accumulates on tooth surfaces within hours of a meal; if not removed, it mineralizes into calculus (tartar) within days and provides a substrate for bacterial biofilm that causes gingivitis, periodontal bone loss, and ultimately tooth loss. Daily dental care is essential, but many pet owners struggle to maintain tooth brushing compliance.
Ceva Clenz-A-Dent Plaqueoff (formerly known as ProDen PlaqueOff) is a sprinkle powder made from a specific strain of natural seaweed (Ascophyllum nodosum) that works systemically — added to food daily, it is absorbed into the bloodstream and is then secreted in saliva, where it modifies the bacterial biofilm adhesion properties on tooth and gum surfaces. This makes plaque softer and easier to naturally remove through chewing and normal oral activity, reducing the need for brushing.
How It Works
Unlike topical dental products that must be applied directly to the teeth, Plaqueoff works from the inside out. The active component of Ascophyllum nodosum is absorbed systemically after ingestion, reaches the saliva, and alters the biochemical properties of dental plaque — making it less adherent to tooth enamel and gingival tissue. Clinical studies have demonstrated reductions in plaque and tartar accumulation with daily use.

Supplement Advisor's Note
Clenz-A-Dent Plaqueoff is one of the few dental supplements with genuine peer-reviewed evidence behind it — multiple studies have demonstrated its efficacy in reducing plaque and tartar when used daily. It is most effective as a preventive tool and as a complement to professional dental cleanings, not as a substitute for them. For cats and dogs that refuse tooth brushing — the majority — it offers a practical, palatability-neutral alternative that pet owners can realistically maintain long-term. Allow 4–8 weeks of consistent use before assessing results.
Frequently Asked Questions
How long until I see results with Plaqueoff?
Most pet owners notice softer tartar and improved breath within 3–8 weeks of daily use. Teeth with heavy existing tartar may require a professional cleaning first to provide a clean starting surface.
Is Clenz-A-Dent Plaqueoff safe for cats?
Yes — it is formulated for both dogs and cats. Cats typically receive one scoop daily added to wet food, which masks any mild seaweed taste.
Does this replace tooth brushing?
Tooth brushing remains the gold standard for home dental care. Plaqueoff is a highly effective complement or alternative when brushing is not feasible — particularly for cats or resistant dogs.
Is the product the same as ProDen PlaqueOff?
Clenz-A-Dent Plaqueoff and ProDen PlaqueOff share the same active ingredient (Ascophyllum nodosum) and mechanism of action. Ceva distributes Clenz-A-Dent through veterinary channels.
