The link between a pet’s diet and their oral health

When it comes to caring for our pets, it’s easy to think of them in human terms—we love them like family, after all.

We brush our teeth, limit sugary treats and worry about cavities, so it feels natural to assume the same principles apply to our furry companions.

However, pets aren’t small, fluffy humans. Their oral health doesn’t follow the same patterns as ours, and its relationship to diet is simply different.

At Advanced Animal Dentistry, our specialist dental team offer a full range of veterinary dental services to preserve animal smiles.

While feeding a nutritionally balanced diet appropriate for their age, size and health conditions is essential, it may not have the same impact on their oral health as you might imagine—especially if you’re comparing it to caring for the dental needs of human children!

The difference between human dentistry
and animal dentistry

While human and animal dentistry shares some overlap, they focus on different challenges. Humans often face tooth decay due to sugar-rich diets and the structure of their teeth, while periodontal disease is a less common concern. In animals, however, periodontal disease is the primary issue, affecting the tissues that support the teeth rather than the teeth themselves.

Tooth decay is rare in pets due to their anatomy, diet and saliva composition. Unlike human teeth, pet teeth do not have the complex grooves that make decay more likely. Additionally, pets typically consume low-sugar diets, and their saliva has a higher pH, creating an environment that discourages the bacteria responsible for cavities.

Pet and human teeth have functions that extend beyond eating. While humans primarily use their teeth for chewing, they are also involved with speech and facial shape. Pets rely on theirs for a range of activities, including grooming, carrying objects, playing, exploring their environment and defence.

The role of diet in overall health vs oral health

A balanced diet supports your pet’s overall health, which indirectly helps maintain healthier teeth and gums. Proper nutrition strengthens the immune system, aiding in the prevention of infections, including those that can affect the gums.

During a pet’s growth and development, diet plays a crucial role in building strong teeth and bones. Puppies and kittens need adequate calcium and other essential nutrients to develop healthy teeth and jaw structures. Once their teeth are fully formed, the diet has less direct impact on their strength or resilience.

Even in cases where metabolic disorders cause weak or brittle bones, this doesn’t necessarily mean the teeth themselves are compromised.

Teeth and bones are distinct in their structure and composition, meaning a condition affecting one doesn’t always affect the other. For instance, a dog with a metabolic issue might have fragile jaws but still retain healthy, functional teeth.

Common dietary myths and misconceptions

Working in animal dentistry, we often encounter common ideas about pet diets that aren’t supported by facts, such as the belief that wet food causes gum disease. Many pet owners worry that softer food might stick to teeth and lead to problems. However, the primary cause of gum disease in pets is poor oral hygiene, not the type of food they consume. Wet food can be part of a healthy, balanced diet.

Another common idea is that dry food cleans teeth. While dry kibble can provide a mild abrasive effect on the teeth it comes into contact with, it doesn’t clean the entire mouth and isn’t sufficient for maintaining oral health alone. Many pets swallow kibble without significant chewing, which reduces its potential benefits.

Sugar-rich or sticky foods, though rarely given intentionally, can negatively impact a pet’s health. Treats like lollies, biscuits or sugary human snacks, if fed frequently, can contribute to problems. Sticky foods cling to teeth and promote bacterial growth. Offering a complete, balanced diet ensures pets get the nutrients they need while reducing the risk of unnecessary health issues.

Practical advice for maintaining your pet’s oral health

Adequate hydration is crucial for supporting a healthy oral environment. Saliva plays a key role in washing away food particles and maintaining a balanced oral microbiome. Ensuring your pet has constant access to fresh, clean water helps keep their gums and teeth in good condition. For cats, placing water bowls away from food can encourage better hydration.

Dental treats and toys can be helpful but use them cautiously. Be aware that substances like bones, antlers and hooves can pose a risk of tooth fractures. Alternatively, choose dental products that are vet-approved and always supervise your pet during chew time to ensure safety.

Brushing your pet’s teeth regularly remains the gold standard for maintaining their oral health at home. While it may take time for cats and dogs to become comfortable with the process, daily brushing helps remove plaque and prevent the buildup of harmful bacteria that cause periodontal disease. A soft-bristled toothbrush, similar to a toddler’s toothbrush, is ideal for ensuring a gentle yet effective cleaning routine.

Does your cat or dog need specialist veterinary care?

Ultimately, when it comes to dietary choices for your pet, supporting their overall systemic health is the top priority. Choose foods that provide a complete and balanced diet, avoiding items you know are harmful, such as sugary treats, chocolate or overly hard chews. If your pet has underlying health conditions or specific dietary needs, consult your primary veterinarian to select the best options for their unique requirements.

At Advanced Animal Dentistry in Brisbane and the Gold Coast, we specialise in addressing concerns related to your pet’s oral health.

While diet has little direct impact on teeth, gums or jaw structures, it plays a key role in your pet’s overall systemic health. By focusing on their general wellbeing, you’re laying the foundation for a healthier mouth and a happier life.
