Short answer: A dental powder is a complementary feed you sprinkle over your pet's food once a day, measured by body weight from the pack. It supports normal oral hygiene from the inside, helping to reduce plaque build-up between cleans. Start with about a quarter serving and build up over a week or two, choose a cat-labelled powder for cats, and ask your vet first if your pet has a thyroid condition or takes medication.
What a dental powder does
Dental powders are complementary feeds: foods for healthy animals, not medicines. Our kelp-based powder uses Ascophyllum nodosum, a Nordic kelp, with other botanicals, to support normal oral hygiene and help reduce plaque build-up between cleans. It works alongside brushing, not instead of it.
In the Petdentist® range
- Petdentist® Advanced Natural Plaque Remover Powder. A Nordic kelp base with botanicals, served by body weight.
- Petdentist® Probiotics Powder for Cats & Dogs. A 90 g bottle with a 3 g scoop. Read the dog evidence and the cat evidence first.
- Petdentist® High Fibre Probiotic + CoQ10 Powder. A 500 g tub of fibre-based powder with a 10 g scoop. It contains bran, so it is not gluten-free.
How to choose
- Species. The pack must name your pet's species and give a serving for it. For cats, choose a powder labelled for cats, with no essential oils, phenols or high-iodine kelp.
- Age. Complementary feeds are designed for healthy pets. For puppies, kittens, and pregnant or nursing animals, follow the pack, and ask your vet if it gives no guidance.
- Size. The serving depends on body weight, so weigh your pet rather than guess.
- Diet. If your pet eats a veterinary diet or must avoid certain ingredients, read the full ingredient list with your vet.
How to serve it
Serve once a day over, or mixed into, food, using the scoop provided and the serving for your pet's body weight on the pack. Follow the pack, not a guess. Start with about a quarter serving for the first few days and build up to the full serving over a week or two, so digestion can adjust. For cats, mix the serving into a small portion of wet food first, then offer the rest of the meal. Use the same meal every day, and keep the pack sealed, cool and dry.
What a powder cannot do
A powder cannot disturb plaque along the gumline the way a brush or wipe does. It cannot remove tartar that has already hardened or reach below the gumline. It is not a medicine and is not a response to any symptom. If you notice red or bleeding gums, a broken tooth or breath that suddenly worsens, see your vet before trying any product.
Safety notes, including kelp and cats
- Kelp and iodine. Kelp is naturally rich in iodine, and thyroid conditions are common in older cats. If your pet has a thyroid condition or takes thyroid medication, ask your vet before using any kelp-containing powder.
- Health conditions and medication. Ask your vet first, and take the pack with you.
- No xylitol, onion or garlic. Every Petdentist® product is xylitol-free. Never share human supplements or sweetened foods with pets.
- Tummy changes. If stools stay loose for more than a couple of days, or your pet vomits or goes off their food, stop and speak to your vet.
- Never withhold food to persuade a cat to accept a powder. A cat that is not eating needs a vet.
When to see your vet
If you notice loose or wobbly teeth, swelling, discharge, bleeding that does not settle, reluctance to eat, dropping food, drooling, pawing at the mouth or any change in behaviour, please contact your veterinary surgeon promptly. Home care supports professional care — it never replaces it.
Where it fits: Step 2, Support
Powders are Step 2 of the Petdentist Daily System: the daily addition to food that works between cleans. Step 1, cleaning along the gumline with a soft brush or textured wipe, still comes first.
