Why Dental Health Matters in Pets
Dental disease is the most common health condition in both dogs and cats, yet it often goes unnoticed. The World Small Animal Veterinary Association Global Dental Guidelines state that by age three, 70% of cats and 80% of dogs have already developed dental issues, but because pets usually continue eating and behaving normally, many owners miss the early warning signs.
Bad breath, drooling, and difficulty chewing can all indicate dental issues but these signs may not appear until dental problems are advanced. Left untreated dental issues don’t just cause tooth loss and infections, it can have widespread consequences, affecting vital organs like the heart, kidneys, and liver. That's why it's important to be a proactive pet parent and stay on top of your pet's dental care with preventative measures.
And one of the easiest and most effective ways you can make a difference to your pet's dental health is with a specially formulated dental food.
The Role of Diet in Dental Health
The food your pet eats every day can play a powerful role in improving their dental health. Specially formulated dental foods work in several important ways.
Unlike regular kibble, dental kibbles like Hill’s Science Diet Oral Care are specifically designed with unique features that help clean teeth effectively. Dental kibbles are typically larger with a special fibre texture designed to mechanically remove plaque and tartar with every bite. The act of chewing a larger kibble with interlocking fibres physically scrubs the surface of the teeth, removing plaque before it hardens into tartar.
Secondly, dental foods are often designed with unique shapes that encourage proper chewing to help scrape plaque on the teeth. Dental foods may also have powerful nutrients like antioxidants and omega-3 fatty acids to help support both gum health and the immune system.

Introducing a Dental Diet to Your Pet
Like any dietary change, it's best to introduce a new dental diet, like Hill's Oral Care, gradually over 7 days to avoid digestive upset. Mix it in with your pet's current food and increase the amount of the new food each day. While this food is suitable for most adult pets, it's a good idea to speak with your vet to ensure it's the right fit for your pet's specific needs.
For optimal results, dental diets work best when combined with other oral care strategies like tooth brushing, annual dental checkups, and the use of vet-approved dental chews or toys.
Dental care is a daily commitment-but it doesn't have to be difficult. With a special dental care diet, like Hill's Science Diet Oral Care, keeping your pet's teeth cleaner becomes as simple as feeding them each day.
