ProDen PlaqueOff
A genuinely simple, well-researched daily dental supplement: one natural seaweed ingredient, no brushing battle, and a strong clinical and vet-recommendation pedigree. It scores well on transparency and trust but sits in a higher price tier per gram than some local plaque powders, and the single-ingredient kelp is high in iodine, so it is worth checking with your vet before starting a pet with thyroid concerns. Use it alongside a complete diet, dental chews and regular check-ups rather than as a replacement, and follow the weight-based scoop dosing on the label. Not veterinary advice.
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.

Pros & cons
What works

Watch-outs

Who it's for
Best for
- Owners who want a fuss-free, brush-free daily way to support dental hygiene
- Dogs and cats prone to tartar and plaque build-up between professional cleans
- People who prefer a single-ingredient, naturally sourced supplement with clinical backing
