Most dog owners feed their dogs every day, take them for walks, and give them plenty of love. But there is one thing that the majority of dog owners overlook completely — their dog’s teeth.
Studies show that by the age of three, over eighty percent of dogs already have some form of dental disease. That is not a small problem. Dental disease in dogs causes chronic pain, difficulty eating, tooth loss, and — if bacteria from the mouth enter the bloodstream — serious damage to the heart, kidneys, and liver.
The good news is that most dental disease in dogs is entirely preventable. It does not require expensive equipment or professional training. It just requires consistency and the right knowledge.
This guide will teach you everything you need to know about dog dental care — from brushing technique to the best dental products, warning signs of dental disease, and when to see a vet.
Why Dog Dental Care Is So Important
A dog’s mouth is home to hundreds of types of bacteria. After every meal, these bacteria mix with saliva and food particles to form a soft, sticky film on the teeth called plaque.
If plaque is not removed through brushing or chewing, it hardens within twenty-four to forty-eight hours into a substance called tartar, also known as calculus. Tartar is yellow or brown in color, rock-hard, and cannot be removed by brushing at home. Only a professional dental cleaning under anesthesia can remove tartar once it has formed.
As tartar builds up along and below the gumline, it causes:
- Gingivitis — inflammation and redness of the gums. This is the earliest and most reversible stage of dental disease.
- Periodontitis — a deeper infection that damages the bone and tissue holding teeth in place. This stage causes pain, loose teeth, and tooth loss.
- Systemic infection — bacteria from severe dental disease can enter the bloodstream and damage the heart valves, kidneys, and liver. This is a serious and life-threatening complication.
Dogs are very good at hiding pain. A dog with severe dental disease may continue eating normally and behaving happily — while silently suffering significant oral pain every day. This is why regular dental checks and preventive care matter so much.
Signs of Dental Disease in Dogs
Learn to recognize these warning signs so you can act before the problem becomes serious:
Bad breath — the most common and often the first sign noticed by owners. A dog’s breath should not smell pleasant, but a distinctly foul or rotten smell indicates bacterial infection in the mouth. This is not normal and should not be ignored.
Yellow or brown deposits on the teeth — visible tartar buildup, especially along the gumline and on the back teeth.
Red, swollen, or bleeding gums — healthy gums are pale pink and firm. Red, puffy, or bleeding gums indicate gingivitis.
Pawing at the mouth — a dog that frequently paws at their face or rubs their mouth on the floor or furniture is likely experiencing oral pain or discomfort.
Dropping food while eating is a sign that chewing is painful. The dog may also eat more slowly than usual or favor one side of the mouth.
Loose or missing teeth — advanced dental disease causes teeth to become loose and eventually fall out.
Visible swelling on the face — a swollen area below the eye or along the jaw can indicate a tooth root abscess, which is a painful infection at the root of a tooth. This requires urgent veterinary attention.
Reluctance to chew toys or play tug — a dog that suddenly loses interest in chewing may be experiencing mouth pain.
Drooling more than usual — increased saliva production can be a response to oral pain or infection.
If your dog shows any of these signs, schedule a vet appointment as soon as possible. Dental disease does not improve on its own — it only gets worse with time.
How to Brush Your Dog’s Teeth at Home
Daily tooth brushing is the single most effective thing you can do for your dog’s dental health. It removes plaque before it has a chance to harden into tartar.
Many dog owners never try brushing because they assume their dog will not allow it. The truth is that most dogs can be trained to accept and even enjoy tooth brushing — if the introduction is done slowly, patiently, and with plenty of positive reinforcement.
What You Will Need
Dog toothbrush — choose a soft-bristled toothbrush designed for dogs. Options include:
- A long-handled dog toothbrush similar in shape to a human toothbrush
- A finger toothbrush — a soft rubber cap that fits over your finger. This gives you more control and is often easier to use on small dogs.
- A double-headed toothbrush — cleans both sides of the tooth at the same time

Dog toothpaste — this is absolutely essential. Never use human toothpaste on a dog. Human toothpaste contains fluoride and xylitol, both of which are toxic to dogs. Dog toothpaste comes in flavors that dogs enjoy — chicken, beef, peanut butter, and vanilla mint are popular options. The appealing flavor makes dogs more cooperative during brushing.
Step-by-Step Introduction for a Dog That Has Never Been Brushed
Do not start by immediately putting a toothbrush in your dog’s mouth. The introduction should be gradual — spread over one to two weeks — to build comfort and trust.
Days 1 to 3 — Introduce the toothpaste flavor
Put a small amount of dog toothpaste on your finger and let the dog lick it off. Do this once a day. Praise enthusiastically. The goal is for the dog to associate the taste with something positive.
Days 4 to 6 — Touch the teeth and gums with your finger
Put toothpaste on your finger and gently rub it along the outside of the upper teeth and gums. Keep sessions to about thirty seconds. Praise and reward after each session.
Days 7 to 9 — Introduce the toothbrush
Let the dog sniff and lick the toothbrush with toothpaste on it. Do not brush yet — just let them get comfortable with the object.
Days 10 to 14 — Begin gentle brushing
Apply a small amount of toothpaste to the brush. Lift the lip gently on one side and brush the outer surfaces of three to four teeth using small, gentle circular motions. Keep the first sessions very short — fifteen to thirty seconds. Reward and praise immediately after.
Week 3 onwards — Full mouth brushing
Gradually work up to brushing all teeth on both sides of the mouth. A full brushing session should take about two minutes.
Brushing Technique
Focus on the outside surfaces of the teeth — this is where tartar builds up most. You do not need to brush the inside surfaces because the tongue naturally keeps those surfaces cleaner.
Hold the brush at a forty-five-degree angle to the tooth surface, angling the bristles toward the gumline. Use small circular or back-and-forth motions. Pay special attention to the large carnassial teeth — the big premolars and molars at the back — as these accumulate the most tartar.
How Often to Brush
Daily brushing is ideal. Studies show that brushing at least five times per week is effective at significantly reducing plaque and tartar. Brushing less than three times per week provides minimal benefit.
Build brushing into a daily routine — after the evening walk or before bed works well for many owners. Routine helps both you and your dog remember.
Dental Products That Support Oral Health
Brushing is the gold standard, but several other products can support your dog’s dental health — especially on days when brushing is not possible.
Dental Chews
Dental chews work through the mechanical action of chewing — as the dog gnaws on the chew, the abrasive texture scrubs the tooth surface and helps reduce plaque and tartar.
Look for dental chews that carry the Veterinary Oral Health Council — VOHC — seal of approval. This seal means the product has been independently tested and proven to reduce plaque or tartar.
Popular VOHC-approved options include Greenies, Virbac CET chews, and OraVet dental hygiene chews.
Give one dental chew per day. Do not use dental chews as a replacement for brushing — use them as a supplement.
Always supervise your dog with dental chews. Choose a size appropriate for your dog — a chew that is too small is a choking hazard, and one that is too hard can fracture teeth.
Avoid chews that are harder than the tooth itself. A good rule of thumb is the thumbnail test — if you cannot make a dent in the chew with your thumbnail, it is too hard and can crack teeth. This rules out real bones, antlers, and very hard nylon chews.
Water Additives
Dental water additives are liquids you add to your dog’s drinking water daily. They contain antibacterial ingredients that reduce the bacteria responsible for plaque formation.
They are tasteless and odorless — most dogs do not notice them in their water. They are not as effective as brushing, but provide a useful additional layer of protection.
Again, look for products with the VOHC seal.
Dental Sprays and Gels
Dental sprays and gels are applied directly to the teeth and gums. They contain antibacterial enzymes that help break down plaque. They are easier to use than a toothbrush for dogs that strongly resist brushing.
Apply daily by lifting the lip and spraying or applying gel along the gumline. No brushing required — the dog’s tongue spreads the product as they lick.
Dental Diets
Certain prescription dental diets are formulated with larger kibble sizes and specific fiber orientations that create a scrubbing effect as the dog bites through the kibble. Hill’s Prescription Diet t/d and Royal Canin Dental are the most well-known options, and both carry VOHC approval.
These are not necessary for every dog, but for dogs that strongly resist all other dental care options, a dental diet provides some passive benefit.
Raw Meaty Bones
Raw bones — not cooked — provide significant mechanical cleaning of the teeth through the act of gnawing. Many holistic vets recommend raw meaty bones as part of a dental care routine.
However, raw bones carry risks, including bacterial contamination, digestive upset, and the possibility of tooth fractures on very hard bones. If you choose to give raw bones, always supervise and choose appropriately sized, softer raw bones like raw chicken necks or raw beef ribs. Never give cooked bones — they splinter into sharp pieces that can perforate the digestive tract.
Professional Dental Cleaning at the Vet
Even with excellent home care, most dogs benefit from a professional dental cleaning every one to three years. Some dogs — particularly small breeds, which are more prone to dental disease — may need annual cleanings.
Professional dental cleaning at the vet is performed under general anesthesia. This is necessary because a thorough cleaning requires scaling below the gumline — something that cannot be done safely or effectively on a conscious dog.
The procedure includes:
- Full mouth examination and dental X-rays to assess the roots and bone below the gumline
- Ultrasonic scaling to remove tartar from all surfaces of every tooth
- Subgingival cleaning — removing tartar from below the gumline
- Polishing to smooth the tooth surface and slow future plaque accumulation
- Extraction of any teeth that are fractured, severely diseased, or cannot be saved
Many owners are concerned about anesthesia, particularly for older dogs. The risk of anesthesia is real but small — and in most cases, the risk of leaving severe dental disease untreated is significantly greater than the risk of the anesthesia itself. Modern veterinary anesthesia protocols are very safe, and your vet will perform pre-anesthetic blood work to assess your dog’s health before the procedure.
A note on anesthesia-free dental cleaning: Some grooming salons and pet shops offer dental cleaning without anesthesia. This cannot clean below the gumline — where the real damage happens. It only removes visible tartar from the crown of the tooth, leaving the roots untreated. Veterinary dentistry organizations worldwide do not recommend anesthesia-free cleanings as a substitute for proper professional dental care.
Dog Dental Care by Breed
Some breeds are significantly more prone to dental disease than others. If your dog is one of the following, be especially diligent with dental care:
Small and toy breeds — Chihuahuas, Yorkshire Terriers, Dachshunds, Maltese, Pugs, Shih Tzus, and similar small breeds have teeth that are often crowded and misaligned because their teeth are too large for their small jaws. This creates more spaces for plaque to accumulate and makes dental disease much more likely. Small breeds often need professional cleanings more frequently — sometimes annually.
Brachycephalic breeds — flat-faced breeds like Bulldogs, French Bulldogs, Pugs, and Boxers have compressed jaw structures that cause significant crowding and misalignment of teeth. Dental disease is extremely common in these breeds.
Greyhounds and Sighthounds — these breeds are genetically predisposed to poor enamel quality and periodontal disease, regardless of diet or home care.
Starting Dental Care With an Adult Dog That Has Never Been Brushed
If your dog has never had their teeth brushed and already has visible tartar buildup, the first step is a professional cleaning at the vet. Brushing over existing tartar does not remove it — it only prevents new plaque from accumulating.
After the professional cleaning, start the brushing introduction process described above. With a clean slate and a gradual introduction, most adult dogs learn to accept brushing within two to three weeks.
Dental Care for Puppies
Start dental care as early as possible — ideally as soon as you bring your puppy home. Even before the adult teeth come in, you can rub a soft cloth or finger brush along the gums to get the puppy used to having their mouth handled.
When the adult teeth come in — between three and seven months of age — begin using a soft puppy toothbrush and dog toothpaste. Puppies that are introduced to tooth brushing early almost always accept it easily as adults.
Be gentle during the teething period — the gums are tender when new teeth are coming through.
Final Thoughts
Dog dental care is not complicated. It does not require expensive equipment or a lot of time. A two-minute brushing session each evening and an annual or biannual vet checkup is enough to protect most dogs from the pain and health consequences of dental disease.
The hardest part is simply building the habit. Start today — even if your dog is already an adult and has never been brushed before. It is never too late to start protecting their health.
Your dog cannot brush their own teeth. They are completely dependent on you for this part of their care. And when you think about the pain of untreated dental disease — the constant aching gums, the infected roots, the difficulty eating — the two minutes it takes to brush their teeth each night seems like a very small investment for a very large reward.
