Periodontal (gum) disease affects an estimated 80% of dogs over the age of 3 and is the most common clinical condition seen in small animal veterinary practice. It's also almost entirely preventable. Here's what actually works.
The Gold Standard: Daily Toothbrushing
Daily toothbrushing with an enzymatic toothpaste is the most effective dental intervention available. Enzymes in the toothpaste break down the bacteria in plaque chemically — so even imperfect brushing is effective. Key points:
- Use dog-specific toothpaste only — human toothpaste contains xylitol, which is toxic to dogs
- A finger brush is often easier for dogs new to brushing than a traditional handle brush
- Focus on the outer surfaces of the upper back teeth — these accumulate the most tartar
- Build up gradually: finger in mouth → toothpaste on finger → finger brush → full brush
When Brushing Isn't Happening
For dogs that won't tolerate brushing, dental chews are the next best option — specifically those with the VOHC (Veterinary Oral Health Council) seal. This seal means independent testing has verified the product reduces plaque or tartar. Greenies and Purina DentaLife both carry it.
Dental water additives (added to drinking water) are a third option, though the evidence is weaker. They're best used as a supplement to brushing or chews, not a replacement.
The Annual Dental Check
No product replaces a professional dental cleaning under anaesthesia for dogs with existing tartar buildup. This typically needs to happen every 1–3 years depending on breed (small breeds accumulate tartar faster) and the owner's home care routine.
