ProDen PlaqueOff
ProDen PlaqueOff is a Swedish-made oral-care supplement built around a single clinically studied kelp ingredient, Ascophyllum nodosum (marketed as A.N ProDen). You sprinkle the fine powder onto your pet's normal food once a day and it works systemically through saliva to make tooth surfaces less hospitable to plaque-forming bacteria, helping reduce tartar build-up and bad breath over a 3-8 week period. In Australia the range is brought in by Troy Laboratories under the "Troy ProDen PlaqueOff" name and is sold mainly as dog and cat powders in 40g and 180g tubs. It is one of the most recognised, vet-recommended dental supplements on the market, with a long track record and VOHC recognition behind the original formula.
