Dental Health in Dogs: What You Need to Know

The statistic that surprises most dog owners: by age 3, approximately 80% of dogs have active periodontal disease — and the vast majority of those dogs show no obvious symptoms. No crying, no pawing at the mouth, no refusal to eat. Dogs are stoic about dental pain in a way that makes them easy to overlook. By the time an owner notices a smell or a reluctance to chew, the disease has typically been progressing quietly for months or years.

What periodontal disease actually means is this: bacteria accumulate along the gumline, forming plaque. If not disrupted, plaque mineralizes into tartar, which is the hard yellow-brown buildup you can see on a dog's molars. Below the gumline — where you cannot see without dental radiographs — tartar causes inflammation, bone loss, and eventually loose teeth. The bacteria involved do not stay in the mouth; they enter the bloodstream and have been linked to changes in heart, kidney, and liver tissue in dogs with long-term severe disease.

The gold standard is a professional dental cleaning under anesthesia, done annually for most dogs and more frequently for small breeds who are genetically predisposed to crowded dentition. At Harlow, we take dental radiographs on every patient — not just the teeth that look bad. You cannot assess the extent of periodontal disease without imaging, and about 60% of what we find and need to treat is invisible to the naked eye. If extractions are needed, we discuss them with you before proceeding, and we provide a detailed estimate. No surprises at checkout.

At home, daily tooth brushing with a dog-specific toothpaste is the single most effective thing you can do between professional cleanings. Use a soft brush or a finger brush and a pea-sized amount of enzymatic toothpaste (never human toothpaste — xylitol is toxic to dogs). Start slowly, with just finger contact on the teeth, and build up over two to four weeks. For dogs who truly will not tolerate brushing, water additives, dental chews certified by the Veterinary Oral Health Council (VOHC), and dental diets (Hills t/d, Royal Canin Dental) are evidence-based adjuncts. Nothing replaces brushing, but something is better than nothing.
