Border Terrier Breed Overview
The Border Terrier is a small, hardy working terrier from the Anglo-Scottish border region, bred to hunt foxes and other vermin alongside horses and hounds. Despite their compact size, Border Terriers have surprisingly large teeth relative to their body — a trait that historically helped them grip prey. This robust dentition also means they need consistent oral care to prevent tartar accumulation and periodontal disease.
Border Terriers typically weigh 11–16 pounds and live 12–15 years. They are known for their wiry, dense coats and otter-shaped heads. Their relatively wide jaw and well-spaced teeth are an advantage: compared to smaller toy breeds, Border Terriers have less dental crowding and therefore lower baseline risk for early tartar buildup.
Border Terrier Dental Anatomy
Like all dogs, the Border Terrier has 42 permanent adult teeth: 12 incisors, 4 canines, 16 premolars, and 10 molars. Their scissor bite is ideally suited for their working heritage — strong, precise, and well-aligned. A correct bite helps the teeth wear evenly and reduces the risk of trauma-related fractures that can occur with misaligned bites.
Their canine teeth are proportionally large and require particular attention during brushing. The premolars are the teeth most likely to accumulate tartar, as they are partially hidden by the cheeks and harder to clean effectively with a standard toothbrush. A finger brush or angled toothbrush head helps access these surfaces.
Common Dental Problems in Border Terriers
Periodontal disease remains the most prevalent health condition in Border Terriers, as it is across all dog breeds. The progression typically begins with plaque — a sticky film of bacteria — accumulating along the gumline. Without regular brushing, plaque mineralizes into tartar within 24–72 hours. Once tartar forms, it irritates the gums, causing gingivitis, and can eventually lead to deeper periodontal pocketing, bone loss, and tooth loss.
Broken teeth are a risk for active working-type terriers. Border Terriers tend to be enthusiastic chewers, and hard objects like antlers, real bones, or hard nylon chews can fracture carnassial teeth (upper fourth premolars). A fractured carnassial tooth almost always requires extraction or root canal treatment.
Tooth root abscesses can develop from advanced periodontal disease or tooth fractures. Because the molar and premolar roots extend close to the sinuses in dogs, a root abscess can sometimes cause facial swelling below the eye — a classic presentation called a carnassial abscess or malar abscess.
Brushing Your Border Terrier’s Teeth
Border Terriers are generally cooperative dogs that respond well to consistent, positive training. Introducing toothbrushing during puppyhood — ideally from 8 weeks — dramatically increases acceptance in adulthood. Start by touching the lips and gums daily, then progress to a finger brush, then to a regular dog toothbrush over 2–3 weeks.
Aim for daily brushing with an enzymatic dog toothpaste (CET, Petrodex, or Arm & Hammer are well-regarded brands). Enzymatic toothpastes contain glucose oxidase and lactoperoxidase enzymes that continue breaking down plaque even after brushing stops — providing hours of additional protection. Never use human toothpaste, as it contains fluoride and often xylitol, both toxic to dogs.
Focus on the outer tooth surfaces (cheek-facing sides) of the premolars and molars, as these are the highest-tartar zones. The inner surfaces (tongue-facing sides) are partially cleaned by saliva and tongue action. A single toothbrushing session should take 1–2 minutes for a thorough clean.
Dental Chews and Supplements for Border Terriers
For Border Terriers, choose dental chews in the small-to-medium range (10–25 lbs). VOHC-accepted products include Greenies, CET Hextra, and Virbac C.E.T. chews. VOHC acceptance means the product has been clinically shown to reduce plaque or tartar by at least 10–15% compared to controls — a modest but meaningful benefit when combined with brushing.
Dental water additives (chlorhexidine or enzyme-based) can be added to the drinking water bowl to reduce oral bacteria. They work continuously throughout the day but cannot replace mechanical plaque removal. Some dogs dislike the taste of water additives; always introduce them gradually.
Professional Dental Cleaning Schedule
Most Border Terriers benefit from professional dental cleaning every 1–2 years. During annual wellness exams, your veterinarian will score your dog’s teeth for tartar accumulation, gingival inflammation, and pocket depth to determine when professional cleaning is needed.
Professional cleaning under general anesthesia includes ultrasonic scaling above and below the gumline, polishing, full-mouth radiographs, and extraction of any teeth beyond salvaging. The procedure typically costs $300–$700 depending on location and the extent of disease. While anesthesia always carries some risk, modern veterinary protocols make it extremely safe for healthy dogs of all ages.
Dental Care for Border Terrier Puppies
Border Terrier puppies begin losing their 28 deciduous teeth around 3–4 months of age. The full adult dentition of 42 teeth is usually in place by 6–7 months. During teething, puppies may chew vigorously to relieve gum discomfort. Provide appropriate chew toys — soft rubber toys, rope toys, and puppy-specific chews — and redirect chewing away from inappropriate objects.
Watch for retained deciduous teeth. If a baby tooth is still present after the permanent tooth has erupted beneath it, two teeth will be in the same socket. This creates food trapping points and dramatically increases tartar risk. Retained teeth should be extracted promptly by your veterinarian, ideally during the spay/neuter procedure.
Warning Signs of Dental Disease
- Persistent bad breath beyond normal dog breath — a sign of bacterial overgrowth
- Yellow-brown tartar deposits on teeth, especially premolars
- Red, swollen, or bleeding gums — gingivitis or periodontitis
- Difficulty eating or dropping food — oral pain
- Swelling below the eye — possible carnassial tooth abscess
- Pawing at the face — oral pain or discomfort
Any of these signs warrants a veterinary examination. Early treatment of dental disease is less invasive and more affordable than managing advanced periodontitis.
