Dental disease affects 80% of dogs over age 3. This practical guide shows you how to introduce teeth brushing, choose the right tools, and establish a routine your dog will tolerate.

Most dogs don't love having their teeth brushed - but with a patient, gradual introduction, the vast majority can be taught to tolerate it. Given that dental disease affects over 80% of dogs by age 3 and is a leading cause of chronic pain, it's absolutely worth the effort.

**Why brush your dog's teeth?**

Plaque (a biofilm of bacteria) forms on tooth surfaces within hours of eating. Within 24–48 hours, mineralised plaque becomes tartar - the hard, rough, yellow-brown deposits you see on uncleaned teeth. Tartar provides a rough surface for more bacteria to adhere to, and once below the gumline, bacteria cause gingivitis (gum inflammation) that progresses to periodontitis (damage to the bone and ligaments supporting teeth).

Brushing removes plaque before it hardens into tartar. Once tartar forms, brushing can prevent it getting worse but cannot remove it - that requires professional cleaning under anaesthesia.

**What you need**

Pet toothbrush: A soft-bristled brush designed for dogs. Finger brushes also work well, especially for introduction. Never use a hard-bristled brush.
Enzymatic pet toothpaste: Critical point - never use human toothpaste. It contains fluoride (toxic to dogs), and often xylitol (extremely toxic). Enzymatic toothpastes have a chemical component that breaks down plaque even without perfect brushing, and come in flavours dogs enjoy (poultry, beef, seafood). This encourages acceptance.
Treats: For reward and positive association

**The gradual introduction process**

Week 1: Taste the toothpaste

Simply put a small amount of toothpaste on your finger and let your dog lick it off. Do this daily. The goal is purely positive association.

Week 2: Touch the teeth

With your finger (no brush yet), gently lift your dog's lip and touch the outer tooth surfaces with your toothpaste-coated finger. Keep it brief. Reward generously.

Week 3: Introduce the brush

With toothpaste on the brush, gently introduce the brush to the outer (buccal) surfaces of the back teeth - these are the most important surfaces for preventing periodontal disease and the easiest to access. Let your dog dictate the pace.

Week 4+: Full brushing

Aim to cover all outer tooth surfaces in a gentle circular or small scrubbing motion. The inner surfaces are naturally cleaned by the tongue. Spend 30–60 seconds total. Always end on a positive note.

Practical tips

- Daily is ideal; three times weekly is a meaningful improvement over no brushing - Choose a consistent time (e.g., after dinner) - Keep sessions brief and positive - never force or restrain your dog - Never scold if your dog is reluctant; just stop and try again the next day

**Adjuncts to brushing** (helpful but cannot replace brushing):

VOHC-approved dental chews (look for the Veterinary Oral Health Council seal)
Dental water additives
Dental diets with mechanical cleaning action
Regular professional dental cleaning (frequency varies by individual)
