Dog Dental Health: How Diet Affects Your Dog's Teeth
6-minute read · Reviewed against the Loyal Saints nutrition standard
Quick answer
Dental disease is one of the most common health problems in dogs, and diet plays a real role. Sugary, starchy kibble can promote plaque, while a clean, low-starch, whole-food diet reduces that dietary contribution. Diet supports dental health alongside — not instead of — regular brushing and veterinary cleanings.
By some estimates, the majority of dogs show signs of dental disease by age three. It's not just about bad breath — untreated dental disease can affect the whole body. While no food replaces brushing and professional cleanings, diet is a genuine contributing factor that's within your control.
How diet affects dental health
The starches and sugars in many kibbles break down into simple sugars that feed plaque-forming bacteria. A diet low in these refined carbohydrates — like a whole-food, freeze-dried raw diet free of corn, wheat, and added sugars — reduces that dietary fuel for plaque. Some whole foods, like crunchy apple and carrot, can also provide gentle mechanical cleaning.
Supporting your dog's dental health
Feed a low-starch, sugar-free diet
Reduces the dietary sugars that feed plaque-forming bacteria.
Brush regularly
Daily or several-times-weekly brushing remains the gold standard for dental care.
Schedule veterinary cleanings
Professional cleanings address tartar that brushing can't, on your vet's recommended schedule.
Watch for warning signs
Bad breath, red gums, difficulty eating, or pawing at the mouth warrant a vet visit.
The Loyal Saints approach supports dental health from the diet side: no corn, wheat, soy, or added sugars in any formula, and clean whole-food ingredients. Small breeds — which are especially prone to dental disease — benefit most from a clean, low-starch diet, though every dog still needs brushing and regular veterinary dental care.

Frequently Asked Questions
Does dog food affect dental health?
Yes, to a degree. Sugary, starchy foods promote plaque-forming bacteria, while a clean, low-starch, sugar-free diet reduces that dietary contribution. However, diet supports dental health alongside brushing and professional cleanings — it doesn't replace them.
Is kibble better for dogs' teeth than raw food?
This is a common myth. While the crunch of kibble was long thought to clean teeth, most kibble shatters without meaningful scraping action, and its starches and sugars actually feed plaque. A clean, low-starch diet — whatever the format — combined with brushing is what supports dental health.
What are signs of dental disease in dogs?
Bad breath, red or inflamed gums, yellow-brown tartar, difficulty or reluctance to eat, drooling, and pawing at the mouth. Small breeds are especially prone. Any of these signs warrants a veterinary dental evaluation.
How can I support my dog's dental health through diet?
Feed a diet free of corn, wheat, soy, and added sugars to reduce plaque-feeding starches. Loyal Saints contains none of these. Combine a clean diet with regular brushing and veterinary cleanings for the best dental health.
