Hills Prescription Diet t/d Dental Care: How It Works

Quick answer

Hills Prescription Diet t/d Dental Care Dry Dog Food cleans your dog's teeth mechanically as they chew, using a special fiber matrix that scrubs plaque and tartar from the gum line.

How Hills t/d kibble cleans teeth step by step

1. Step 1: Kibble size and shape force chewing: Each piece is oversized compared to regular kibble. Your dog must bite down and chew rather than swallow whole. This extends the contact time between the kibble and every tooth surface. Check that your dog is actually chewing — if they gulp, try moistening the kibble slightly to slow them down.
2. Step 2: Fiber matrix technology scrubs as the dog bites: When the dog bites into the kibble, the unique fiber matrix expands and presses against the tooth surface. The fibers act like a scrub brush, dislodging plaque and food debris from the enamel and along the gum line. Do not soften the kibble into mush — the mechanical scrubbing action only works when the kibble retains its structure.
3. Step 3: Tartar control continues after the meal: The abrasive action also helps remove existing stain and tartar deposits. Over weeks of consistent feeding, the visible buildup on teeth gradually decreases. The effect is cumulative, not instant. Expect visible improvement after 2–4 weeks of exclusive feeding. Mixing with other foods dilutes the cleaning effect.
