Which Dogs Is It For?
Dogs of every size from 12 weeks old whose breath makes you turn your head, whose back teeth are going yellow-brown, or who simply won't let a toothbrush near them. Small breeds, flat-faced dogs and seniors tend to build up plaque fastest, so they benefit most from a daily routine.
Bad breath isn't "just dog breath". Most of the time it comes from plaque, a sticky film of bacteria that builds up on the teeth after every meal. This powder works on it at every meal, sprinkled on the food.
Not for cats. If your dog is pregnant, nursing, on medication, under treatment or has a thyroid condition, ask your vet first.
The 6 Things This Formula Was Built For
Six everyday goals, one sprinkle a day:
✓ Fresher breath, with kelp, probiotics, rosemary and green tea
✓ Less plaque build-up, with kelp (Ascophyllum nodosum)
✓ Less tartar build-up: sodium hexametaphosphate helps keep plaque from hardening
✓ A balanced mouth, with two friendly probiotic strains
✓ Cleaner-looking teeth, month after month
✓ No brushing battle: sprinkle it on the food, once a day
Not a toothbrush, not a chew, not a water additive. A fine powder that disappears into the food.
How It Works
Plaque starts within hours of every meal. Food leaves a sticky film on your dog's teeth, and the bacteria living in it multiply fast. Those bacteria make the sulphur compounds behind that sour "dog breath" smell. Left alone, plaque hardens into yellow-brown tartar within days, mostly on the back teeth where you can't see it.
Brushing works, if your dog lets you. Most don't. Dental chews disappear in seconds and only scrape the teeth they touch.
This works while your dog eats. Kelp (Ascophyllum nodosum), the brown seaweed at the heart of the formula, helps reduce plaque and tartar build-up. Sodium hexametaphosphate, a mineral, binds the calcium that turns soft plaque into hard tartar. Probiotics support a balanced mouth, and rosemary and green tea help keep breath fresh. One sprinkle on the food, once a day.
What to Expect — Your First 90 Days
Here's what dog parents typically tell us. Every dog is different, so give it a full 90 days of daily use.
Week 1: one sprinkle on the food becomes routine; most dogs don't notice it's there.
Weeks 2–4: many owners notice fresher breath.
Month 2: less new build-up and cleaner-looking teeth, especially at the back.
Month 3: a fresher mouth becomes normal, which is why most dog parents keep going.
Owner-reported experiences, not a promise. Tartar that has already hardened won't simply disappear: if there's a lot of it, ask your vet about a dental check.
How To Use
Sprinkle the dose on your dog's food once a day, wet or dry (slightly moistened kibble holds it best). Do not add it to water. Use the scoop inside the jar:
Up to 12 lb (5.5 kg): ½ scoop
12–25 lb (5.5–11 kg): 1 scoop
25–75 lb (11–34 kg): 1½ scoops
Over 75 lb (34 kg): 2 scoops
Each jar holds 60 scoops: 60 days for a dog on 1 scoop a day, 30 days for a dog on 2. Suitable from 12 weeks old. Do not exceed the recommended dose. Keep the jar closed in a cool, dry place.
Complementary feed for dogs, not a medicine: it does not replace a balanced diet, your vet's advice or dental care at the vet. Ask your vet first if your dog is pregnant, nursing, on medication, under treatment or has a thyroid condition. Not for cats. Follow the dosing table for your dog's weight. Red or bleeding gums, loose teeth, pain or a dog that stops eating need a vet, not a supplement. Keep out of reach of children.

What dog parents report after 4 weeks of Dental Powder
What dog parents are actually saying
“Bella's breath used to clear the sofa. Three weeks of a sprinkle on her dinner and the cuddles are back.”
Claire M. & Bella · Bad breath“Lola's little teeth were going brown at the back. Now they look cleaner, and she has no idea she's getting anything.”
Sophie L. & Lola · Tartar build-up“Max is the biggest face-licker alive. Six weeks in, I actually let him.”
Nadia B. & Max · Fresh breath
It's Not "Just Dog Breath". It's Plaque.
Breath That Clears the Room
That sour smell isn't "just dog breath". It comes from the bacteria living in plaque. Kelp, probiotics, rosemary and green tea help keep your dog's breath fresh, starting at the next meal.
Yellow-Brown Build-Up on the Back Teeth
Plaque that stays on the teeth hardens into tartar within days, mostly on the back teeth you never see. Kelp (Ascophyllum nodosum) and sodium hexametaphosphate help reduce plaque and tartar build-up, every day.
The Brushing Battle You Always Lose
You know you should brush. Your dog disagrees. With a powder on the food there's nothing to hold and nothing to fight: one sprinkle, and dinner is served.
Chews Gone in Ten Seconds
Dental chews get gulped down in seconds, only touch some of the teeth and add calories every day. A fine powder is part of every meal, at almost no calories.
Kelp, Probiotics & 3 More Actives in Every Scoop
Kelp 330 mg
Ascophyllum nodosum, a brown seaweed from the cold North Atlantic. The heart of the formula: it helps reduce plaque and tartar build-up and supports fresh breath.
Probiotics 450M CFU
Two friendly bacteria, P. pentosaceus and L. plantarum, that support a balanced mouth and fresher breath.
Mineral SHMP 58 mg
Sodium hexametaphosphate binds the calcium in saliva, so soft plaque is less likely to harden into tartar.
Rosemary 40 mg
Rosemary leaf extract, a natural plant extract rich in antioxidants that helps keep breath fresh.
Green Tea
Decaffeinated green tea (4.6 mg per scoop), with plant polyphenols that support fresh breath and healthy gums.
Chicken Liver Taste
Hydrolysed chicken liver gives the powder a savoury taste most dogs love, so it disappears into the bowl. Hydrolysed means broken down, easy to digest.
Your First 90 Days on Dental Powder
The first week was just about seeing if she'd eat it. She didn't even notice it was there.
Week 1
An easy routine
One sprinkle on the food becomes part of mealtime. Most dogs eat it without noticing, and there's nothing to brush and nothing to fight.
- 🦴 Part of every meal
- 🐶 Eaten without fuss
- 🙌 No brushing battle
Around week three I realised I'd stopped turning my head away when she yawned.
Weeks 2–4
Fresher breath
With kelp, probiotics, rosemary and green tea at every meal, this is when many owners notice fresher breath, and close cuddles stop being a test of nerves.
- 🌿 Fresher breath
- 🤗 Close cuddles again
- 😊 No more turning away
Two months in, I lifted his lip and the back teeth looked cleaner than I'd seen them in years.
Month 2
Cleaner-looking teeth
Used every day, kelp and sodium hexametaphosphate help reduce new plaque and tartar build-up. Many owners see cleaner-looking teeth, especially at the back.

Month three. At twelve, his mouth smells fresh again. I'm not stopping now.
Month 3
A fresh mouth, every day

Questions About Dental Powder
Does a powder really work without brushing?
Daily brushing is still the gold standard, and if your dog lets you, keep doing it. Most dogs don't, and that's who this is for. The powder works at every meal: kelp (Ascophyllum nodosum) helps reduce plaque and tartar build-up, sodium hexametaphosphate helps keep plaque from hardening, and probiotics, rosemary and green tea support fresh breath. No brushing needed: just sprinkle it on the food.
My dog is on medication, pregnant or nursing. Can I use it?
Ask your vet first, and show them the ingredient list. The same goes for dogs under treatment, with a thyroid condition (kelp naturally contains iodine) or with ongoing digestive problems.
Syntro Dental Powder is a complementary feed, not a medicine. It does not replace your vet's advice or any treatment your vet has prescribed.
Can my cat have it too?
No. It's made for dogs only, and the dose is based on a dog's weight. Please don't give it to cats.
Can I use it with dental chews or my dog's other supplements?
Yes, it can generally be used alongside your dog's usual food, treats and supplements. Don't combine it with another product that contains kelp or iodine without asking your vet. If your dog takes medication, see the question above.
Does it replace dental cleaning at the vet?
No. It's a daily routine that helps keep plaque and tartar build-up down and breath fresh between check-ups, not a replacement for your vet. Tartar that has already hardened won't simply disappear. Keep your dog's regular check-ups, and see your vet if you notice red or bleeding gums, loose or broken teeth, pain when chewing, or a dog that stops eating.
What's actually inside it?
Per scoop (1.5 g): kelp (Ascophyllum nodosum) 330 mg, sodium hexametaphosphate 58 mg, rosemary leaf extract 40 mg, decaffeinated green tea 4.6 mg and probiotics (Pediococcus pentosaceus, Lactiplantibacillus plantarum) 450 million CFU.
Other ingredients: calcium bentonite, dried brewer's yeast, hydrolysed chicken liver (flavour), spinach powder. 60 scoops per jar, scoop included.
Is it safe? What about allergies or a sensitive tummy?
It's made for daily use in dogs from 12 weeks old, at the dose for their weight. The chicken liver is hydrolysed, which breaks the protein down so it's easy to digest; if your dog has a known allergy to chicken or yeast, ask your vet first. Anything new in the bowl can upset a sensitive tummy at first: start with half the dose for a few days and always give it with the meal. Do not exceed the dose for your dog's weight. Keep out of reach of children.
My dog is a picky eater. Will they eat it?
Most dogs don't notice it. The powder is fine, with a savoury chicken liver taste, and it sticks best to wet food or slightly moistened kibble. If your dog hesitates, start with a pinch and build up to the full dose over a week.
How quickly will I notice fresher breath?
Many owners notice fresher breath within 2 to 4 weeks, and cleaner-looking teeth over 2 to 3 months. Every dog is different, so give it a full 90 days of daily use. You have 90 days to decide, risk-free.
How much do I give?
Once a day, sprinkled on the food, by weight: Up to 12 lb (5.5 kg) ½ scoop · 12–25 lb (5.5–11 kg) 1 scoop · 25–75 lb (11–34 kg) 1½ scoops · Over 75 lb (34 kg) 2 scoops. The scoop is in the jar. A jar holds 60 scoops: 60 days on 1 scoop a day, 30 days on 2.
Do I need to keep using it?
Plaque comes back after every meal, so the routine works best every day. Most dog parents keep going to keep that fresh breath; stop, and build-up tends to return over the following weeks. That's why the 3-jar option is the most popular.
