Are Dental Chews Actually Cleaning Your Dog's Teeth?
Dental chews are everywhere.
They’re easy to give, dogs usually love them, and many promise cleaner teeth, less plaque, reduced tartar and fresher breath.
I saw a commercial the other day that made the dog chew look like an edible toothbrush that will keep their breath fresh and their teeth pearly and white.
Question is... are they really effective and what does your dog ingest for that 10,000 watt smile?
The claims of "reduces plaque or tartar," "cleans your dog's teeth," and "is something I'm comfortable giving my dog every day for long-term health" may not all be wrapped up in 1 chew.
So let's take a closer look at what dental chews actually do, what they don't do, and what else is worth considering before that edible toothbrush becomes part of your dog's daily routine.
🦷 First: Plaque and Tartar Aren’t the Same Thing
Before we talk about whether dental chews “work,” it helps to understand what they’re supposed to be working on.
Plaque is a soft, sticky bacterial biofilm that continuously forms on the teeth. If it isn’t regularly disrupted, bacteria within mature plaque can contribute to gum inflammation and the progression of periodontal disease.
Tartar, also called dental calculus, forms when minerals in saliva become deposited into plaque and the plaque hardens.
Once tartar has formed, it becomes much more difficult to remove through routine at-home dental care.
That distinction matters because a product may help reduce plaque, tartar or both — and those aren’t necessarily the same dental benefit.
So... Do Dental Chews Actually Work?
Some do.
Dental chews can work through several different mechanisms, depending on the product:
- Mechanical friction as the teeth penetrate or rub against the chew
- Shapes or textures designed to increase contact with the teeth
- Ingredients designed to interfere with tartar formation
- A combination of mechanical and chemical action
There’s also an independent way to determine whether a particular product has evidence behind its dental claims, the VOHC Seal.
What Does the VOHC Seal Mean?
The Veterinary Oral Health Council (VOHC) evaluates data submitted by manufacturers seeking acceptance for plaque control and/or tartar-control claims.
Products that meet its standards may receive the VOHC Seal of Acceptance.
That’s useful information when evaluating a dental chew, but look closely at what the seal actually says. A product may be accepted for plaque control, tartar control or both.
In other words, don’t assume every product marketed as “dental” has demonstrated the same benefit and more importantly, VOHC does NOT evaluate the safety of the ingredients in the chew.
🪥 Chewing Isn’t the Same as Actively Cleaning
This is where an important distinction gets lost.
A dog chewing on something and you intentionally wiping or brushing the teeth along the gumline are fundamentally different mechanical actions.
Plaque is a sticky biofilm. To remove it, you need direct physical contact that disrupts that film on the tooth surface.
That can be done with a soft-bristled toothbrush, finger brush, gauze wrapped around your finger or another gentle dental tool your dog comfortably accepts.
The important part isn’t which tool you choose. It’s that you can intentionally clean the teeth, including surfaces and areas along the gumline that chewing may not consistently reach.
When your dog chews:
- Some teeth may receive much more contact than others
- Contact depends on how your individual dog chews
- Back teeth may receive considerably more chewing action than front teeth
- The gumline may not be cleaned consistently
- Some tooth surfaces may receive very little meaningful contact
A dental chew only makes contact where and how your dog happens to chew it.
Intentional cleaning gives you something chewing can’t: Control over where the cleaning happens.
Does That Mean Dental Chews Are Useless?
No, but it also isn't black and white.
A dental chew doesn’t become useless simply because intentionally cleaning your dog’s teeth provides more controlled access to the tooth surfaces and gumline.
A well-designed chew may provide a measurable dental benefit. Some dogs also enjoy chewing, which can provide enrichment and satisfy a completely normal behavior.
The problem comes when a dental chew is expected to carry your dog’s entire dental care routine.
Reducing some plaque or tartar through chewing isn’t necessarily the same as consistently cleaning the areas where plaque accumulates throughout the mouth.
And more importantly ... they don't look at the long term health effects of the chews.
🔎 A Dental Chew Is Also Something Your Dog Eats
There’s another difference between a dental chew and a mechanical disruption you control:
Your dog eats the chew.
Dental chews have to be manufactured as edible products. They need to hold together, maintain the intended texture, remain shelf stable and taste appealing enough that dogs want to chew them.
Depending on the formulation, that may require:
- Starches, flours or other structural ingredients
- Humectants such as glycerin to help maintain moisture and texture
- Flavoring or other palatability ingredients
- Ingredients used for freshness, appearance or shelf stability
- Ingredients specifically intended to help control tartar
That doesn’t automatically make those ingredients bad or unsafe.
It simply means a dental chew is both a dental product and a food product.
So read the ingredient panel just as you would for any other product your dog regularly eats.
Ask what each ingredient is doing and why it’s there.
We’ll dig much deeper into dental-chew ingredients — including sodium hexametaphosphate (SHMP) and why 4-Legger chooses not to use it — in our next article.
🍖 Don’t Forget the Calories
Because dental chews are food, they also contain calories.
Depending on the product and size, a daily dental chew can contribute a meaningful amount to your dog’s overall calorie intake.
That may not be a concern for every dog. But for smaller dogs, dogs who receive other treats throughout the day or dogs whose weight needs to be carefully managed, those calories can add up.
If you give a dental chew every day, check the calorie content for the specific product and size you’re feeding and include it in your dog’s overall daily intake.
A dental chew may have a dental purpose, but your dog’s body still counts it as food.
🦴 Can a Chew Just Be a Chew?
Absolutely.
Dogs like to chew. Chewing can provide enrichment, occupy time and satisfy a completely normal canine behavior.
We just don’t think chewing and dental care have to be the same thing.
Our dogs get bully sticks because they enjoy chewing them — not because we rely on them to clean their teeth. We prefer to choose a simple, appropriate chew for enrichment and handle dental care separately through intentional cleaning of the teeth and gumline.
If your dog enjoys a dental chew and you’re comfortable with its ingredients, calories and demonstrated dental benefit, it may have a place in your dog’s routine too.
Just give it the right job.
A chew can just be a chew. And a dental chew can complement dental care without replacing it.
🔎 What Should You Look for in a Dental Chew?
If you decide to give your dog a dental chew, look beyond the claims on the front of the package.
- Look for evidence. Has the product demonstrated plaque reduction, tartar reduction or both? If it carries the VOHC Seal, check which claim the seal covers.
- Read the complete ingredient panel. Remember that your dog will be swallowing the entire product so select chews that won't impact their long term health.
- Check the calories. A daily chew becomes part of your dog’s daily food intake.
- Choose the correct size. Follow the manufacturer’s sizing recommendations for your dog.
- Consider your individual dog. Size, chewing style, diet and health needs all matter.
- Supervise chewing. Any edible chew can present a choking or obstruction risk if a dog swallows a piece that is too large.
- Keep expectations realistic. A dental chew may complement an oral-care routine, but it shouldn’t be expected to clean every tooth surface and the entire gumline.
💚 The 4-Legger Bottom Line
Yes, some dental chews can help clean your dog’s teeth.
But that statement needs context.
Some have demonstrated reductions in plaque. Some help control tartar. Some do both. Their mechanical action depends on where and how your dog chews, and they don’t give you the same control over cleaning the teeth and gumline that intentional brushing or wiping provides.
That doesn’t make dental chews bad.
It means they should be understood for what they actually do — and what they don’t.
If you use one, look at the evidence behind the dental claim. Read the ingredients. Count the calories. Supervise your dog. And don’t assume that giving a daily dental chew means the rest of your dog’s oral health is taken care of.
Because “helps reduce plaque or tartar” and “cleans my dog’s teeth” aren’t always the same thing.
Frequently Asked Questions About Dog Dental Chews
Are dental chews actually effective?
Some are. Certain dental chews have demonstrated reductions in plaque, tartar or both, and some have earned the Veterinary Oral Health Council (VOHC) Seal of Acceptance.
Not every dental chew works equally well, so look for evidence supporting the specific product’s claims.
Do dental chews remove plaque?
Some dental chews have demonstrated plaque reduction. Their mechanical action comes from contact and friction between the chew and the teeth.
However, how much contact occurs — and which teeth receive it — depends on the product and how your individual dog chews.
Do dental chews remove tartar?
Some dental chews can help reduce tartar formation, but existing hardened tartar is much more difficult to remove through routine at-home care.
If your dog already has significant tartar buildup, talk with your veterinarian about whether professional dental care is needed.
What does the VOHC Seal mean on a dog dental chew?
The Veterinary Oral Health Council evaluates data submitted to support plaque-control and/or tartar-control claims. Products that meet its standards may receive the VOHC Seal of Acceptance.
Check the specific seal because a product may be accepted for plaque control, tartar control or both.
Can dental chews replace brushing or wiping my dog’s teeth?
No. Dental chews may provide some mechanical cleaning where the chew contacts the teeth, but they don’t provide the same controlled access to tooth surfaces and the gumline.
A soft-bristled toothbrush, finger brush, gauze or another gentle dental tool your dog accepts allows you to intentionally disrupt plaque where it accumulates.
Can I give my dog a dental chew every day?
Follow the directions for the specific product and consider the chew as part of your dog’s overall diet. Check its ingredients and calories, choose the appropriate size for your dog and supervise chewing.
Can dental chews be a choking or obstruction risk?
Yes. Any edible chew can present a choking or gastrointestinal obstruction risk if a dog swallows a piece that is too large.
Choose an appropriately sized product, consider your dog’s chewing style and supervise your dog while they chew.
When does my dog need professional dental care?
Home dental care helps maintain oral health, but it can’t treat established periodontal disease.
Talk with your veterinarian if you notice persistent bad breath, red or bleeding gums, loose or damaged teeth, significant tartar buildup, difficulty eating, facial swelling, pawing at the mouth or other signs of oral pain or discomfort.
