A practical guide to spotting dental pain early and building a simple home-care routine.
Dog dental health guide
Quick Answer
Common dental problems in dogs include periodontal disease, plaque and tartar buildup, broken teeth, and persistent bad breath. Daily brushing, safe chews, VOHC-accepted products, and regular vet dental checks are the best ways to prevent painful oral disease.
Key Takeaways
- Periodontal disease is the most common dog dental problem, affecting an estimated 80–90% of dogs over age three.
- Bad breath is not “just dog breath” if it is strong, persistent, or paired with red gums, drooling, or trouble eating.
- Brushing works best, but dental chews, diet, and vet cleanings all play a role in prevention.
Why Dog Dental Health Matters
Dog dental health affects comfort, appetite, and quality of life. A sore mouth can make a dog avoid food, drop kibble, chew on one side, or stop enjoying toys.
Periodontal disease starts quietly. Plaque forms when bacteria mix with saliva and food particles. If plaque stays on the teeth, it hardens into tartar. That tartar traps more bacteria near the gumline.
Cornell’s veterinary team notes that 80–90% of dogs over age three have some level of periodontal disease. The AVMA also describes periodontal disease as the most common dental condition in dogs and cats by age three. (vet.cornell.edu)
A Corgi owner in Sai Ying Pun recently told me her dog “suddenly became picky.” Her vet found two loose molars and inflamed gums. The dog was not being fussy. She was in pain.
1. Periodontal Disease in Dogs
Periodontal disease is infection and inflammation around the teeth, gums, and supporting bone. It usually begins as gingivitis, which means red, swollen gums.
Signs of Periodontal Disease
Watch for:
- Bad breath
- Red, swollen, or bleeding gums
- Yellow or brown tartar near the gumline
- Dropping food
- Chewing on one side
- Pawing at the mouth
- Loose or missing teeth
- Less interest in chew toys
The tricky part? Dogs hide pain well. By the time they stop eating, disease may already be advanced.
How It Is Treated
Treatment usually involves a professional dental cleaning under anaesthesia. Vets may also take dental X-rays to see disease below the gumline. AAHA notes that periodontal staging is most accurate under anaesthesia with intraoral radiographs and periodontal probing. (aaha.org)
Food texture alone will not fix periodontal disease. But a complete, balanced diet supports overall health while you manage the mouth. For owners moving away from ultra-processed food, Furry Green’s gently cooked meals can fit into a broader dental care plan alongside brushing and vet checks.
2. Plaque and Tartar Buildup
Plaque is soft. Tartar is hard. That difference matters.
Plaque can be brushed away. Tartar usually needs professional removal.
Plaque vs Tartar
| Issue | What it looks like | Can brushing remove it? | Main risk |
|---|---|---|---|
| Plaque | Clear, sticky film | Yes, if done regularly | Gum irritation |
| Tartar | Yellow, tan, or brown crust | No, not once hardened | Bacteria trapped at gumline |
| Gingivitis | Red or swollen gums | Sometimes improves with early care | Progression to periodontal disease |
| Advanced periodontal disease | Loose teeth, pain, infection | No | Tooth loss and chronic pain |
Brush daily if you can. If not, aim for at least several times a week. Use dog toothpaste only. Human toothpaste may contain ingredients that are unsafe for pets.
3. Broken or Fractured Teeth
Broken teeth are common in dogs that chew hard objects. Antlers, weight-bearing bones, rocks, ice cubes, and very hard nylon toys can crack teeth.
A simple rule helps: if you would not want to hit your kneecap with it, it may be too hard for your dog’s teeth.
Signs of a Broken Tooth
Look for:
- Sudden reluctance to chew
- Bleeding from the mouth
- A visible crack or missing tooth piece
- Face rubbing
- Sensitivity while eating
- Bad breath after a chewing injury
If the pulp is exposed, bacteria can enter the tooth. That can lead to infection or an abscess.
Treatment may include bonding, root canal therapy, or extraction. Your vet will decide based on the tooth, fracture depth, and X-rays.
4. Bad Breath in Dogs
Bad breath is one of the easiest dental signs to notice. It is also one of the easiest to ignore.
Mild food smell can happen after meals. Strong, sour, metallic, or rotten breath is different. It may point to periodontal disease, an infected tooth, trapped food, oral growths, or another health issue.
My colleague’s dog had this exact issue during a humid summer. Everyone blamed the weather and wet food storage. A dental exam found infected gums behind the back teeth.
If your dog eats gently cooked food, clean the bowl after every meal. With Furry Green meals or any fresh food, remove leftovers promptly, especially in humid weather. This supports hygiene, though it does not replace toothbrushing.
5. Which Dogs Are Most at Risk of Dental Problems?
While any dog can develop dental disease, certain breeds, ages, and medical conditions increase the risk of oral health problems.
Small and Toy Breeds
Small-breed dogs are particularly prone to dental disease because their teeth are crowded into a smaller jaw, making plaque and tartar accumulation more likely.
Breeds commonly affected include:
- Pomeranian
- Chihuahua
- Yorkshire Terrier
- Maltese
- Toy Poodle
- Shih Tzu
- Pekingese
- Cavalier King Charles Spaniel
Many of these breeds are also among the most popular companion dogs in Hong Kong, making dental care especially important for local pet owners.
Older Dogs
The risk of dental disease increases with age because plaque and tartar accumulate over time.
Senior dogs are more likely to develop:
- Advanced periodontal disease
- Tooth root infections
- Tooth loss
- Oral masses
- Worn or fractured teeth
Because many dental problems progress slowly, older dogs may have significant oral disease despite appearing otherwise healthy.
Flat-Faced (Brachycephalic) Breeds
Dogs with shortened muzzles often have crowded or misaligned teeth, which can make oral hygiene more challenging.
Examples include:
- French Bulldog
- Pug
- Boston Terrier
- English Bulldog
- Shih Tzu
Crowded teeth create additional areas where plaque and bacteria can accumulate.
Dogs with Certain Medical Conditions
Some health conditions can increase susceptibility to oral disease or make existing dental disease worse.
Examples include:
- Diabetes mellitus
- Chronic kidney disease
- Immune-mediated disorders
- Hormonal diseases such as Cushing's disease
In addition, severe periodontal disease may complicate the management of some chronic illnesses by contributing to ongoing inflammation and infection.
Dogs That Frequently Chew Hard Objects
Dogs that regularly chew on hard items have a higher risk of tooth fractures.
Common culprits include:
- Antlers
- Weight-bearing bones
- Ice cubes
- Rocks
- Hard nylon chew toys
A useful guideline recommended by many veterinary dentists is: if you would not want the object struck against your knee, it may be too hard for your dog's teeth.
Extra Dental Care for High-Risk Dogs
If your dog falls into one of these higher-risk categories, your veterinarian may recommend:
- More frequent oral examinations
- Earlier professional dental cleanings
- Daily tooth brushing
- VOHC-approved dental products
- Regular dental X-rays when indicated
Early intervention is often the best way to prevent painful dental disease and preserve your dog's teeth throughout their life
How to Prevent Dental Disease in Dogs
Dental prevention works best when it is boring and consistent.
Brush Your Dog’s Teeth
Daily brushing is the gold standard for removing plaque before it hardens. Start with the outer tooth surfaces. Keep sessions short. Reward calmly.
Use VOHC-Accepted Products
The Veterinary Oral Health Council reviews products for plaque or tartar control when used as directed. Accepted products may include dental chews, diets, water additives, gels, toothbrushes, and wipes. (vohc.org)
Book Regular Vet Dental Exams
Home care cannot show what is happening under the gumline. Regular oral exams help catch broken teeth, infection, and early periodontal disease before pain becomes obvious.
Fresh Food Can Support a Cleaner, Healthier Routine
Gently cooked fresh dog food will not replace brushing or professional dental care, but it can support your dog’s overall wellbeing with real meat, real vegetables, and no artificial preservatives. Softer, balanced meals can also be easier for dogs with sensitive mouths to enjoy while you work with your vet on a proper dental plan.

What are the most common dental problems in dogs?
The most common dental problems in dogs are periodontal disease, plaque and tartar buildup, broken teeth, and bad breath. Periodontal disease is the biggest concern because it affects the gums, ligaments, and bone supporting the teeth. Left untreated, it can cause pain, infection, and tooth loss.
How do I know if my dog has dental disease?
Signs include bad breath, red gums, tartar buildup, bleeding, drooling, dropping food, chewing on one side, or avoiding hard treats. Some dogs show only subtle changes, such as eating slower or losing interest in toys. A vet dental exam is the safest way to confirm the problem.
Can dental chews replace brushing my dog’s teeth?
No. Dental chews can help reduce plaque or tartar, especially if they carry the VOHC seal, but they do not replace brushing. Brushing physically removes plaque from tooth surfaces. Chews are best used as support, not the whole dental plan.
How often should dogs have dental cleaning?
The right schedule depends on age, breed, mouth shape, diet, and home care. Small breeds and flat-faced dogs may need dental care earlier or more often. Your vet can recommend timing after examining the teeth and gums.
Is bad breath normal in dogs?
Persistent bad breath is not normal. It usually means bacteria are building up in the mouth or there is another dental issue. If bad breath appears suddenly, smells severe, or comes with drooling, bleeding, or poor appetite, book a vet check.
