Oral disease is extremely common in dogs, with over 80% of dogs aged three and older said to have some form of periodontal disease. Problems in the mouth extend beyond bad breath alone—bacteria can travel through the bloodstream and negatively impact the heart, kidneys, and liver. Daily dental care is a vital habit that directly contributes to extending your dog's lifespan.
Why Do Dogs Develop Periodontal Disease?
Each time your dog eats, bacteria multiply in the mouth and form plaque on the tooth surface. Plaque is soft and can be removed with brushing, but if left untreated, it combines with calcium in saliva within approximately 72 hours to transform into tartar. Once tartar forms, it cannot be removed by brushing alone and requires professional scaling by a veterinarian.
Tartar buildup causes gingivitis, and if left to progress, it can lead to periodontitis and alveolar bone resorption (periodontal disease). In severe cases, not only can teeth fall out, but the jawbone can also deteriorate. Additionally, oral bacteria can enter the bloodstream and spread throughout the body, increasing the risk of worsening heart valve disease and chronic kidney disease.
Steps to Establish a Teeth Brushing Routine for Dogs That Resist
Most dogs will resist if you suddenly try to put a toothbrush in their mouth. Follow these steps to gradually acclimate them.
Step 1: Getting Accustomed to Mouth and Face Touching (1–2 weeks)
Start by massaging the outside of the lips with your finger, without using a toothbrush. Pair this with treat rewards so your dog learns that "being touched = good things."
Step 2: Getting Accustomed to Fingers in the Mouth (1–2 weeks)
Gently lift the lips and practice stroking the gums with your finger. Taking dog toothpaste (chicken or beef flavored) on your finger and touching it to the gums will make acceptance easier. Never use human toothpaste (it contains fluoride and xylitol, which are harmful).
Step 3: Getting Accustomed to the Toothbrush in the Mouth (1–2 weeks)
Begin with gauze or a finger brush, starting with the front teeth. Even a few seconds is fine at first. End before your dog shows resistance and always reward with praise to create a positive memory.
Step 4: Transition to Full Brushing (Ongoing)
Use a toothbrush to brush from the canines to the molars. The key is to focus brushing on the line between the teeth and gums (gum line). Since dogs naturally clean the tongue-side (inner surface) with their own tongues, brushing primarily the cheek-side (outer surface) is sufficient.
Types of Dental Products and How to Choose Them
Beyond toothbrushes, there are various other dental care products available. Use them as supplementary care when daily brushing is difficult.
Dental Chews (Treat-style)
These work by physically scraping away plaque through chewing. Products bearing the VOHC (Veterinary Oral Health Council) seal have demonstrated effectiveness. However, most are high in calories, so be mindful not to overfeed.
Dental Gels and Sprays
These are applied or sprayed in the mouth to suppress bacterial growth. They are effective for dogs that are difficult to brush or as supplementary care, but their physical plaque-removal effect is inferior to brushing.
Dental Water (Added to Drinking Water)
An additive that suppresses oral bacteria when mixed into water. It's convenient but serves only a supplementary role.
Rope Toys and Dental Toys
Fibers work between the teeth while chewing, providing mild cleaning effects. They are lower in calories than treat-style chews and allow care while playing.
Professional Scaling by a Veterinarian (Tartar Removal)
No matter how consistently you brush daily, tartar will gradually accumulate. Regular scaling (tartar removal using an ultrasonic scaler) is necessary.
Scaling Frequency
- Dogs brushed daily: Once every 1–2 years
- Dogs brushed 1–2 times per week: Once per year
- Dogs with no brushing routine: Once every 6 months to 1 year
Small breeds (Chihuahuas, Toy Poodles, etc.) have teeth that are closer together and are more prone to periodontal disease, so they often require more frequent scaling than larger dogs.
General Anesthesia is Required for Scaling
Canine scaling is performed under general anesthesia. This allows for proper deep cleaning below the gum line (between teeth and gums), X-ray examination, and tooth extraction if needed. Non-anesthetic scaling can only remove surface tartar and cannot clean below the gum line—the most critical area—so there is a risk of appearance improving while actual periodontal disease progresses.
Early Signs of Periodontal Disease
If you notice any of the following signs, consider consulting your veterinarian promptly.
- Worsening bad breath: A healthy dog's breath is odorless to slightly fishy
- Red or swollen gums: Normal gums are pink and firm
- Bleeding from the gums: Bleeding during brushing or eating is a sign of inflammation
- Loss of appetite or changes in eating habits: Avoiding hard foods, chewing on one side only, etc.
- Reluctance to have the mouth touched: Avoidance behavior due to pain
- Facial swelling: As apical abscesses (pus at the root) progress, cheeks may swell
Summary
The foundation of canine oral care is combining daily brushing with regular scaling. Even if your dog initially resists, most dogs will eventually accept brushing through gradual habit formation. Maintaining oral health is directly linked to your dog living a long, healthy life. Rather than putting teeth brushing aside as a chore, establishing the habit from puppyhood is the best prevention strategy.
