Dental disease affects over 80% of dogs over the age of 3 in Australia. It’s the most common condition treated in veterinary practice — and one of the most preventable. Diet plays an important role, but most owners are surprised to learn which dietary interventions actually have evidence behind them and which are marketing.
This guide separates the evidence-based options from the marketing claims and ranks the best dental dog foods available in Australia.
HOW FOOD AFFECTS DENTAL HEALTH: MECHANICAL CLEANING: Dry kibble creates a mild abrasive action as dogs chew — this reduces plaque accumulation on tooth surfaces. Soft wet food provides no mechanical cleaning. Large-breed kibble that requires actual chewing is more effective than tiny kibble that gets swallowed whole.
HEXAMETAPHOSPHATE COATING: Some dental-specific kibbles are coated with sodium hexametaphosphate (HMP), which binds salivary calcium and reduces tartar mineralisation. This is proven to reduce tartar formation by 20–40% in studies.
FIBRE MATRIX TECHNOLOGY: Hills Oral Care uses a specific fibre matrix that encourages the entire tooth surface to be engaged when chewing — more effective than standard kibble.
VOHC SEAL: The Veterinary Oral Health Council (VOHC) awards a seal of acceptance to products that have demonstrated plaque or tartar reduction in clinical trials. This is the most reliable indicator of efficacy for dental products.
TOP DENTAL DOG FOODS IN AUSTRALIA
Hills Oral Care Adult
VOHC accepted. Clinically proven fibre matrix. The only dry food in Australia with both strong dental evidence AND complete nutritional adequacy. Protein: 24% DM | Price: ~$22–28/kg | Where: Pet Circle, PetBarn, vets
Royal Canin Dental Dry
VOHC accepted. Larger, harder kibble designed to maximise tooth contact. Good supporting evidence. Price: ~$26–32/kg | Where: Pet Circle, PetBarn, vets
Greenies Original Dental Treats — 8.0/10
VOHC accepted for tartar reduction. More effective than food alone when used daily. Not a replacement for food but a strong complement. Note: Calories count — adjust meal size accordingly. Price: ~$25–35/pack | Where: Pet Circle, PetBarn, most pet stores
Black Hawk Original Adult (Lamb & Rice)
Standard dry food provides baseline mechanical cleaning. Not dental-specific but better than wet food for plaque. Most accessible AU option. Note: If dental health is a priority concern, use Greenies alongside.
Varies — Score: High effectiveness
Raw meaty bones (appropriately sized for your dog) provide superior mechanical dental cleaning than any commercial food. The evidence for raw bones and dental health is strong. IMPORTANT CAVEATS: Must be raw (not cooked), must be size-appropriate, must be supervised. Cooked bones splinter and are dangerous. Consult your vet for appropriate bone selection for your dog’s size.
THE TRUTH ABOUT DENTAL FOOD — WHAT IT CAN’T DO
No food — including Hills Oral Care and Royal Canin Dental — replaces professional dental cleaning. If your dog already has significant tartar build-up, scaling under anaesthesia is required. Dental food prevents new tartar from forming and reduces plaque — it does not remove existing tartar.
The dental health hierarchy (most effective → least):
1. Professional scaling under anaesthesia (vet-performed)
2. Daily tooth brushing (proven most effective at-home method)
3. Raw meaty bones (appropriate size/type, supervised)
4. VOHC-approved dental chews (daily use)
5. VOHC-approved dental food
6. Standard dry kibble (mechanical cleaning only)
7. Wet food (minimal dental benefit)
Frequently Asked Questions
Does dry dog food clean teeth?
Standard dry kibble provides modest mechanical cleaning — enough to slow plaque accumulation but not eliminate it. Dental-specific formulas (Hills Oral Care, Royal Canin Dental) are more effective because of their larger kibble and specific texture or coating. Neither replaces daily brushing or professional dental cleaning.
What is the best food for a dog with dental disease?
If your dog already has significant dental disease (tartar build-up, gingivitis, loose teeth), veterinary dental cleaning is required first. After professional cleaning, transition to a VOHC-approved dental food and implement daily brushing or dental chews. Hills Oral Care or Royal Canin Dental are the best post-treatment maintenance foods.
Are dental chews better than dental food?
They serve different purposes and are most effective when used together. Dental food addresses every meal. Dental chews provide more intensive mechanical cleaning but only once daily. The combination of dental food + VOHC-approved daily chews is more effective than either alone.
At what age do dogs get dental disease?
Dental disease begins from around 1–2 years of age in small breeds (who are especially prone due to crowded teeth) and 2–3 years in medium/large breeds. By age 3, over 80% of dogs show some degree of dental disease. Prevention from puppyhood is far easier than treatment.
