VOHC Approved Dog Dental Chews vs. Daily Brushing: Which Is More Effective?
Both reduce plaque — but not equally, not in the same places, and not as substitutes for each other.
If you’ve been giving your dog dental chews and wondering whether you still need to brush their teeth, this guide gives you the clinical evidence to answer that question. We cover what the VOHC seal means, how much plaque each method removes, what daily brushing can do that chews cannot, and how to build a home care plan that actually works.
DIRECT ANSWER
The most common anesthesia risks for dogs during dental cleaning are: transient low blood pressure, respiratory depression, abnormal heart rate, and delayed recovery from anesthesia. The risk of death in a healthy adult dog is approximately 1 in 100,000. Risk may increase in senior dogs, brachycephalic breeds (Bulldogs, Pugs, French Bulldogs), and dogs with undetected heart, kidney, or liver disease. The good news: every major risk is predictable and manageable with proper pre-anesthetic screening, IV fluids, continuous monitoring, and balanced anesthetic protocols.
Plaque & Tartar Reduction: By the Numbers

What Does VOHC Accepted Actually Mean?
The VOHC seal is the only credible third-party standard for pet dental product efficacy.
VOHC ACCEPTED
Veterinary Oral Health Council
Veterinary Oral Health Council (VOHC) Accepted Seal
To earn Accepted for Plaque Control, a product must demonstrate ≥20% plaque reduction in two independent controlled clinical trials. For Tartar Control, the same threshold applies to tartar reduction.
What the VOHC seal does NOT mean: that the product equals brushing, protects against subgingival disease, or reduces the need for professional cleaning. It confirms the product met a minimum efficacy threshold in peer-reviewed controlled trials.
WARNING:
“Clinically proven,” “dentist recommended,” and “helps clean teeth” are NOT equivalent to VOHC Accepted. These phrases have no standardized definition. Only the VOHC seal confirms a product met a pre-specified efficacy threshold in controlled trials. Always look for the VOHC Accepted seal on packaging.

What Each Method Can and Cannot Do
The differences in where, how, and how much each method works determine how they should fit into your dog’s home care routine.
| Daily Toothbrushing | VOHC Dental Chews | ||
|---|---|---|---|
| ✓ | Removes 50–70% plaque from accessible crown surfaces with correct daily technique | ✓ | Reduces plaque by 18–33% through mechanical abrasion on crown surface |
| ✓ | Contacts the gumline directly — the origin point of periodontal disease | ✓ | Reduces calculus by 20–37% through combined mechanical and chemical mechanisms |
| ✓ | Can partially disrupt early subgingival plaque when brush angled 45° at gumline | ✓ | Highly accepted by most dogs — compliance easier to maintain than brushing |
| ✓ | Prevents fresh plaque mineralizing into calculus (must brush before day 3–5) | ✓ | Enzyme chews (CET, OraVet) provide ongoing antibacterial activity after chewing |
| ✓ | Allows owner to visually inspect mouth and detect early changes | ✓ | Best adjunct for dogs that resist brushing or when daily brushing not achievable |
| ✗ | Cannot remove established calculus — only professional scaling can | ✗ | No subgingival contact — cannot reach below gumline where disease originates |
| ✗ | Requires dog acceptance and 3–5 min of daily owner compliance | ✗ | Efficacy depends on chewing pattern — some dogs swallow without adequate chewing |
| ✗ | Does not reach lingual (tongue-side) surfaces equally | ✗ | Adds 25–90 kcal per chew — must account for in daily diet |

Building the Right Home Dental Care Plan for Your Dog
Home care works best as a layered system. No single product or technique protects all tooth surfaces against all disease. Here is the evidence-based hierarchy from most to least effective.
1
Daily Toothbrushing — Gold Standard
Soft-bristled toothbrush angled at 45° toward the gumline, veterinary-formulated toothpaste (never human — fluoride and xylitol are toxic to dogs). Focus on outer surfaces of upper back teeth. Daily is evidence-based; once-weekly has minimal clinical benefit. Most dogs accept brushing well with a few weeks of gradual desensitization.
2
VOHC-Accepted Dental Chews — Best Adjunct
Given once daily after brushing, or as primary home care when brushing is not possible. Choose a chew sized appropriately for your dog — large enough to require actual chewing. Account for calories in daily intake. Best evidence: Virbac CET, Greenies, OraVet, Purina DentaLife. Confirm current VOHC Accepted seal at vohc.org.
3
VOHC-Accepted Water Additives or Dental Rinses — Supplemental
Added to the water bowl or applied directly to gum surfaces. Reduce bacterial load and provide enzymatic or antiseptic activity throughout the day. Cannot replace mechanical plaque removal but add a meaningful chemical layer. Easiest to administer — good option for very resistant dogs.
4
Annual Professional Dental Cleaning Under Anesthesia — Non-Negotiable
No home care regimen prevents subgingival calculus accumulation over time. Professional cleaning with full-mouth X-rays and periodontal probing is the only way to address subgingival disease and identify root abscesses and bone loss. Home care extends the interval between cleanings — it does not eliminate the need for them. Visit aspirevetcenter.com/veterinary-dentistry/ to schedule.
Never use human toothpaste on dogs. Fluoride is toxic to dogs when swallowed, and xylitol — present in many human dental products — is acutely dangerous. Use only veterinary-formulated toothpaste, which is designed to be swallowed safely and comes in flavors dogs accept.
How to Brush a Dog's Teeth Correctly
Brushing technique matters. Most owners brush the visible flat surface of the crown — not where the most disease-relevant plaque accumulates.
Correct Technique
Use a soft-bristled toothbrush with veterinary toothpaste. Lift the lip and angle bristles at approximately 45° toward the gumline — bristles should reach slightly beneath the gum margin. Use small circular strokes. Focus on the outer surfaces of the upper canine and carnassial teeth, where calculus accumulates fastest.
Introducing Brushing to a New Dog
Start by letting your dog lick toothpaste off your finger for several days. Progress to rubbing a finger along the gumline. Introduce the brush and touch teeth briefly before withdrawing — always end on a positive note. Over 2–4 weeks, gradually increase duration and coverage.
Which Teeth Matter Most
Upper fourth premolars (carnassial teeth) and upper canine teeth — highest priority. Upper incisors and lower premolars follow. Focus on outer surfaces if time is limited.
Aspire Veterinary center
Use only veterinary-formulated toothpaste containing no fluoride or xylitol. Enzymatic toothpastes (glucose oxidase or lactoperoxidase systems) add an antibacterial layer beyond mechanical brushing alone.
Frequently Asked Questions (FAQ)
Questions pet owners ask us most about anesthesia during dog dental cleanings.
Are VOHC dental chews as effective as brushing a dog's teeth?
No. Daily toothbrushing removes 50–70% of plaque with correct technique and can partially contact the gumline. VOHC-accepted chews reduce plaque by 18–33% and work only on the visible crown surface. Chews are a useful adjunct — particularly for dogs where daily brushing is not achievable — but are not a functional equivalent to brushing.
What does the VOHC Accepted seal mean?
The VOHC awards its Accepted seal to products that demonstrated at least 20% plaque or tartar reduction in two independent controlled clinical trials. It is the only credible third-party standard for pet dental products. Marketing phrases like “clinically proven” or “dentist recommended” have no standardized meaning and are not equivalent to VOHC Accepted.
Can I use dental chews instead of brushing my dog's teeth?
Chews are better than no home care for owners who cannot brush daily, but they cannot replace brushing. The critical gap is gumline contact: brushing can partially disrupt plaque at the gumline where periodontal disease begins, while chews work only on the crown surface. For dogs where brushing is truly not possible, VOHC chews combined with VOHC water additives provide better protection than chews alone.
How often should I give my dog dental chews?
Most VOHC-accepted dental chews are recommended daily for optimal efficacy — the clinical trials used daily administration. Remember to account for caloric content: a large Greenie contains approximately 60–90 kcal. Adjust the main meal accordingly, especially for dogs prone to weight gain. |
Do dental chews or brushing eliminate the need for professional dental cleaning?
No. Neither brushing nor VOHC chews can prevent subgingival calculus accumulation over time. Professional dental cleaning under anesthesia with full-mouth dental X-rays remains the only way to treat subgingival disease and detect root abscesses and bone loss. Consistent home care extends the interval between professional cleanings — it does not eliminate the need for them.
What is the best VOHC-approved dental chew for dogs?
The best chew is one your dog will chew thoroughly and that fits their diet. Among products with robust evidence: Virbac CET combines mechanical abrasion with an enzyme system; OraVet contains delmopinol to reduce bacterial biofilm adhesion. Greenies and Purina DentaLife have high palatability and VOHC acceptance. Confirm the current VOHC Accepted seal at vohc.org.
