Periodontal disease is the most common clinical condition in adult dogs. According to the American Veterinary Medical Association (AVMA), by the time a dog is three years old, it will very likely have early evidence of periodontal disease — and the condition worsens with age if no preventive action is taken.
The good news: the AVMA also states that regular brushing is the single most effective thing you can do to keep your dog's teeth healthy between professional cleanings, and may reduce the frequency or even eliminate the need for veterinary dental procedures.
This guide covers what you need to know and do, based on guidelines from the AVMA, the American Animal Hospital Association (AAHA), and published veterinary research.
Why Dental Care Is Not Optional
Periodontal disease starts with dental plaque — a microbial biofilm that forms on teeth. Left unchecked, it progresses from gingivitis (inflamed gums, reversible) to periodontitis (bone and tissue loss, irreversible).
The consequences go beyond the mouth. A 2019 study published in Research in Veterinary Science found that bacteria from periodontal disease can enter the bloodstream and reach distant organs. Specific findings from peer-reviewed research:
- Heart: A study of 136 dogs found that 50.67% of dogs with periodontal disease showed cardiac changes, compared to just 3.28% of dogs without it (Veterinary Sciences, 2021)
- Kidneys and liver: For each square centimeter of periodontal disease burden, there was a 1.2x higher likelihood of liver pathology and 1.4x higher likelihood of kidney pathology (Journal of Veterinary Dentistry, 2008)
- General inflammation: The AVMA notes that kidney, liver, and heart muscle changes have been found in association with periodontal disease
| Approach | Estimated Annual Cost |
|---|---|
| Prevention (daily brushing + annual checkup) | $150–$400 |
| Treatment (professional cleaning under anesthesia) | $300–$1,000+ |
| Advanced treatment (cleaning + extractions + specialist) | $1,000–$3,000+ |

Signs Your Dog Needs Dental Attention
Not all dental problems are visible, but these signs should prompt action. They are grouped by urgency:
Act Now (Often Reversible With Home Care)
- Persistent bad breath
- Visible yellow or brown buildup along the gumline (tartar)
- Red or swollen gums, especially where gum meets tooth
- Minor bleeding when chewing hard toys or food
- Increased drooling
See Your Vet This Week
- Difficulty eating or dropping food
- Pawing at the mouth or rubbing the face
- Loose or visibly damaged teeth
- Swelling around the muzzle or under the eyes
- Behavioral changes — reluctance to play, irritability
Emergency — Call Your Vet Now
- Uncontrolled oral bleeding
- Severe facial swelling
- Fever combined with any oral symptoms
- Complete refusal to eat or drink for more than 24 hours
- Pus or discharge from the gums or mouth
How to Brush Your Dog's Teeth (Step by Step)
Daily brushing is the gold standard. The AVMA calls it the single most effective home care measure, and the AAHA's 2019 Dental Care Guidelines reinforce daily home care as a critical complement to professional cleanings.
If daily isn't realistic, the AVMA notes that brushing several times a week can still be effective. Any regular brushing is better than none.
What You Need
- Toothbrush: A dog-specific toothbrush with soft bristles. Finger brushes work for smaller dogs or dogs new to brushing. See our dog toothbrush guide for picks by size and temperament.
- Toothpaste: Dog-specific enzymatic toothpaste only. Never use human toothpaste — it contains fluoride and xylitol, both toxic to dogs.
- Treats: Small, high-value treats for positive reinforcement between steps.
The Brushing Technique
This technique is based on guidance from Cornell University College of Veterinary Medicine and the AVMA:
- Let your dog taste the toothpaste first. Squeeze a small amount onto your finger and let them lick it. Do this for a few days before introducing the brush.
- Lift the lips gently so you can see the teeth and gumline clearly.
- Hold the brush at a 45-degree angle to the gumline. This angle is critical — it reaches the sulcus, the small pocket between tooth and gum where periodontal disease begins.
- Brush with short back-and-forth strokes, about three strokes per tooth or section of teeth.
- Focus on the outer (cheek-facing) surfaces. Dental plaque and tartar accumulate most rapidly on the outer surfaces of the upper teeth. The AVDC recommends targeting these areas first.
- Take breaks. Pause to give treats and praise. Sessions should stay positive — stop before your dog gets stressed.
- Work up gradually. Start with just a few teeth per session and build up to the full mouth over days or weeks.
Target time: 2–3 minutes once you've built up to full coverage.

Choosing Dental Products That Work
The Veterinary Oral Health Council (VOHC) is the standard reference for dental product effectiveness. VOHC awards a Seal of Acceptance to products that meet pre-set criteria for reducing plaque and/or tartar, verified through controlled scientific trials.
Always check for the VOHC Seal. The full list of accepted products is available at vohc.org/accepted-products.
Toothpaste
- Use enzymatic dog toothpaste — the enzymes continue working after brushing stops
- Avoid: human toothpaste, baking soda, or anything containing xylitol, fluoride, or artificial sweeteners
- Flavor matters — dogs are more cooperative with poultry- or beef-flavored paste

Dental Chews
Dental chews are supplements to brushing, not replacements. Look for:
- The VOHC Seal of Acceptance
- Appropriate size for your dog (too small = choking risk; too large = ineffective)
- Chews that require sustained gnawing — the mechanical action is what reduces plaque
VOHC-accepted chew brands include products from Greenies (Mars Petcare) and Tartar Shield, among others.

Water Additives
Water additives with VOHC approval (such as HealthyMouth) can provide a small additional benefit. They are not a substitute for brushing or chews but can be part of a layered approach.
Dental Diets
Prescription dental diets (like Hill's t/d or Purina Pro Plan Veterinary Diets DH) are VOHC-accepted and use kibble size, shape, and texture to mechanically reduce plaque. Discuss with your vet whether a dental diet is appropriate for your dog.
Professional Dental Cleaning: What to Expect
The AAHA's 2019 Dental Care Guidelines recommend professional dental cleanings on a schedule that depends on breed size:
- Small-breed dogs: Starting at 1 year of age
- Large-breed dogs: Starting at 2 years of age
- Frequency: Annually, or as recommended by your vet based on your dog's oral health
Why Anesthesia Is Required
AAHA's position is clear: dental procedures require general anesthesia. Non-anesthetic dental cleanings (NAD) are not recommended because they:
- Only clean visible surfaces (disease starts below the gumline)
- Cannot perform subgingival scaling, probing, or dental X-rays
- Cause stress and risk of injury to the dog
- Create a risk of aspiration
The Procedure
A standard professional dental cleaning follows a protocol outlined in the 2019 AAHA Dental Care Guidelines:
- Pre-anesthetic bloodwork — screens for organ function and anesthesia safety
- General anesthesia — administered via sedation and tracheal intubation
- Full oral exam — each tooth examined, probing depths measured
- Dental X-rays — reveals disease below the gumline (60% of tooth structure is hidden)
- Scaling — ultrasonic and hand instruments remove plaque and tartar above and below the gumline
- Polishing — smooths enamel after scaling to slow future plaque attachment
- Treatment plan — vet discusses findings, including any extractions needed
Recovery
- Expect grogginess for 12–24 hours after anesthesia
- Feed soft food for a few days if extractions were performed
- Full healing from extractions typically takes 7–10 days
- Follow-up medication (antibiotics, pain management) as prescribed
Cost
Based on 2025–2026 veterinary pricing data:
| Procedure | Typical Cost Range |
|---|---|
| Routine cleaning (no extractions) | $300–$700 |
| Cleaning with diagnostics and minor extractions | $600–$1,500 |
| Specialist/surgical treatment | $1,000–$3,000+ |
Factors that increase cost: dog size, age (senior dogs need more extensive pre-op testing), severity of disease, number of extractions, and geographic location.
Care by Life Stage
Puppies (Birth to 12 Months)
Puppies are born without teeth. Here's the dental development timeline, based on AKC and USDA veterinary guidance:
- 3–4 weeks: Deciduous (baby) teeth begin erupting
- 5–6 weeks: All 28 deciduous teeth are in
- 12–16 weeks (3–4 months): Baby teeth start falling out as permanent teeth push through
- 6 months: Most or all adult teeth should be in place
- 8 months: All 42 permanent adult teeth should be present
What to do during this stage:
- Start getting your puppy used to mouth handling early — touch their muzzle, lift their lips, touch their gums with your finger
- Introduce toothpaste on your finger around 8–10 weeks
- Begin brushing with a soft brush or finger brush once permanent teeth start coming in (around 4–6 months)
- Provide appropriate puppy chew toys for teething — frozen washcloths, rubber chew toys
- Ask your vet to check for retained baby teeth at each puppy visit. Retained teeth can cause crowding and dental problems
Adults (1–7 Years)
This is the maintenance window. Dental disease prevention during this stage determines your dog's long-term oral health.
- Brush daily (or at minimum 4–5 times per week)
- Annual vet checkup with oral exam
- Professional cleaning every 1–2 years, or as your vet recommends
- VOHC-approved chews as daily supplements to brushing
- Monitor for warning signs listed above — catch problems early while they're still reversible
Seniors (7+ Years)
Dental disease accelerates with age. Older dogs are more likely to need extractions and may have underlying health conditions that complicate anesthesia.
- Keep brushing. Shorter, gentler sessions if your dog has sensitive gums.
- More frequent vet dental exams — every 6 months if your vet recommends
- Pre-anesthetic bloodwork is essential before any procedure. Senior dogs need comprehensive screening to ensure safe anesthesia.
- Watch for subtle signs: eating slower, preferring soft food over kibble, losing interest in chew toys, weight loss
- Tooth loss is not normal aging — it's untreated disease. If your senior dog loses teeth, see your vet.
Breed-Specific Dental Risk
Not all dogs face the same dental risk. A 2022 study published in Scientific Reports (Royal Veterinary College VetCompass programme, UK) analyzed over 22,000 dogs and found significant breed-based differences.
Small Breeds: Highest Risk
Extra-small breeds (under 6.5 kg / 14 lbs) are up to 5 times more likely to develop periodontal disease than giant breeds (over 25 kg / 55 lbs). Reasons include:
- Smaller jaws with crowded teeth trap food and plaque more easily
- Less bone mass anchoring each tooth, making tooth loss from periodontitis more likely
Highest-risk breeds by odds ratio from veterinary research:
- Toy Poodles (3.97x)
- King Charles Spaniels (2.63x)
- Cavalier King Charles Spaniels
- Chihuahuas
- Yorkshire Terriers
Flat-Faced (Brachycephalic) Breeds
Brachycephalic breeds have 1.25x the risk of dental disease compared to medium-skulled breeds. Their shortened jaws create tooth crowding, misalignment, and rotated teeth that are harder to keep clean. Breeds include:
- Pugs
- French Bulldogs
- English Bulldogs
- Shih Tzus
- Boston Terriers
Greyhounds
Greyhounds show elevated dental disease risk (2.58x odds ratio) despite being a large breed. The exact cause is not fully understood, but genetics and enamel composition are suspected factors.
If your dog is in a high-risk breed: Start professional cleanings earlier (from 1 year), brush daily without exception, and schedule dental checks every 6 months.
Frequently Asked Questions
How often should I brush my dog's teeth?
Daily is ideal. The AVMA states that daily brushing is the most effective home care measure. If daily isn't possible, aim for at least 4–5 times per week — but any regular brushing is better than none.
Can I use human toothpaste?
No. Human toothpaste contains fluoride and often xylitol, both of which are toxic to dogs. Use only toothpaste formulated for dogs.
Are dental chews enough on their own?
No. Dental chews can reduce plaque buildup but are not a replacement for brushing. The AAHA 2019 guidelines recommend brushing combined with other measures like dental diets and chews — not chews alone.
Is anesthesia-free dental cleaning safe?
AAHA does not recommend non-anesthetic dental procedures. They only clean visible tooth surfaces, cannot address subgingival disease, and carry risks of stress, injury, and aspiration. Proper dental cleaning requires general anesthesia.
At what age should my dog get their first professional cleaning?
The AAHA recommends starting at 1 year for small-breed dogs and 2 years for larger breeds, with annual cleanings thereafter.
My dog won't let me brush their teeth. What can I do?
Start slowly. Spend several days just letting them taste the toothpaste, then progress to touching teeth with your finger, then introduce the brush gradually. Keep sessions short and reward heavily. If your dog remains resistant, talk to your vet about alternatives like dental diets and VOHC-approved chews — but keep trying to build tolerance for brushing.
