Dental disease is one of the most common health problems in adult dogs and cats: by around age three, most pets already show early signs. The good news is it's largely preventable with a simple routine: regular brushing or a dental supplement, dental-friendly chews, and a yearly vet check. Prevention is far kinder, and far cheaper, than treating advanced disease later.
- Persistent bad breath is not normal: it's usually the first sign of dental disease.
- Daily brushing is the gold standard, but a sprinkle-on supplement helps pets who won't tolerate a toothbrush.
- Dental chews reduce plaque through chewing but don't replace brushing.
- Never use human toothpaste: it's toxic to pets.
- Book a dental check as part of your pet's yearly vet visit.
Why does my pet's dental health matter so much?
Because it affects far more than their teeth. Plaque hardens into tartar, which inflames the gums and, left unchecked, leads to painful gum disease, tooth loss and infection. The bacteria involved can also enter the bloodstream and place extra strain on the heart, liver and kidneys. Dental pain is easy to miss because pets hide it so well: many simply soldier on while quietly uncomfortable every time they eat.
What are the signs of dental problems?
Keep an eye (and a nose) out for these common warning signs:
- Bad breath: the earliest and most reliable clue; healthy mouths don't smell foul.
- Yellow or brown tartar build-up along the gum line
- Red, swollen or bleeding gums
- Drooling, or pawing at the mouth
- Reluctance to eat hard food, chewing on one side, or dropping food
- Loose or missing teeth
If you spot any of these, book a vet check: dental disease only worsens without treatment.
How do I prevent dental disease at home?
The single most effective step is brushing your pet's teeth with a pet-safe toothpaste, ideally most days. Introduce it slowly and make it positive. For the many pets who simply won't accept a toothbrush, a natural sprinkle-on supplement like Simply Seaweed is a brilliantly easy alternative: you just add it to their food, and it works to reduce plaque and tartar from the inside for both dogs and cats. Combine it with dental-friendly chews and you've covered most pets' needs.
Do dental chews and treats actually work?
They help. The mechanical action of chewing scrapes away softer plaque before it hardens into tartar, so a daily chew is a genuine part of a good routine, just not a replacement for brushing or supplements. Choose a natural chew sized correctly for your pet, such as freeze-dried beef tendon, and always supervise, removing small end pieces. Our healthy dog treats guide explains how to keep chews within a balanced diet.
How does a seaweed supplement help?
It's the low-effort option that actually gets done. A natural dental seaweed is simply sprinkled onto your pet's normal food once a day; as they eat, it helps soften and reduce the plaque and tartar that cause gum disease. Because there's no brushing involved, it suits fussy cats, wriggly puppies and any pet that turns a toothbrush into a wrestling match. It's one of the easiest wins in pet care, which is exactly why Simply Seaweed is one of our most popular products.
Are cats different from dogs when it comes to teeth?
The prevention is the same, but cats deserve special attention. They're very prone to gum inflammation and to painful resorptive lesions, and they're even better than dogs at hiding mouth pain. Watch for a cat that's gone quiet at mealtimes, chews oddly or has developed bad breath. A sprinkle-on supplement suits cats particularly well since so few will tolerate brushing, and pairing dental care with good daily enrichment keeps them healthy all round.
How often should my pet have a professional dental check?
At least once a year, as part of their routine vet visit. Your vet can spot problems hiding below the gum line and will advise if a professional scale and polish (done under anaesthetic) is needed to reset things. Home care between visits is what keeps those professional cleans few and far between.
Frequently asked questions
Is "dog breath" normal?
No: genuinely bad breath is the most common early sign of dental disease, not just a quirk of being a dog or cat. A healthy mouth shouldn't smell offensive. Persistent bad breath is worth a vet check.
Can I use human toothpaste on my pet?
Never. Human toothpaste often contains fluoride and the sweetener xylitol, both of which are toxic to pets, and it isn't meant to be swallowed. Always use a toothpaste made specifically for dogs or cats.
When should I start dental care?
As early as possible. Starting brushing or a dental routine with a puppy or kitten gets them used to it for life, but it's never too late to begin with an adult pet, just introduce it gently and positively.
Is preventive dental care really worth it?
Absolutely. A daily supplement or brush costs very little, while treating advanced dental disease can mean an expensive procedure under anaesthetic and, worse, ongoing pain for your pet. Prevention protects both their comfort and your wallet.
Which dental products suit which pet?
You do not need every category at once. This is how the products in our range divide up, using what their own listings say.
Shaped dental chews
Whimzees makes shaped dental chews for dogs, sized by breed. Shapes in our range include the Hedgehog, Antlers, Stix and Toothbrush designs, sold from extra small through to extra large, plus puppy-specific bags sized for a young dog's smaller mouth.
Classic dental treats
Greenies covers the Sweet Potato flavour for adult dogs, sized Teenie through to Large, plus a Puppy Original line. Greenies cat treats in catnip and chicken flavours are sold as a crunchy everyday reward rather than a dedicated dental chew.
Sprinkle-on supplement
Simply Seaweed is 100% dried and crushed ascophyllum nodosum added to your pet's regular food. Its listing describes natural anti-adhesive and antibacterial properties that help stop bacteria sticking to tooth enamel. One note from the maker's own usage guidelines: because seaweed is naturally high in iodine, it should not be given to pets with thyroid conditions without veterinary supervision.
Sizing chews correctly
Buy the size matched to your dog's breed and weight. An oversized chew is hard for a small dog to manage; an undersized one may be swallowed too quickly by a large dog. Every dental chew listing on our site states its size guide.
