Best Dental Chews for Dogs: Do They Really Clean Teeth?

Last updated: April 27, 2026

Your dog’s breath could strip paint off a fence, and someone — maybe a friend, maybe a pet store employee, maybe the internet — has suggested dental chews as the solution. It is a reasonable idea on the surface. Dental chews for dogs are one of the most popular pet products on the market, promising cleaner teeth, healthier gums, and that elusive thing called fresh breath. But the question that matters is whether they actually deliver on those promises or whether they are just expensive treats with good marketing.

The answer, as with most things in pet care, is somewhere in the middle. Some dental chews genuinely help reduce plaque and tartar. Others are little more than flavored snacks in clever packaging. This guide walks through the science, the safety concerns, and the practical details so you can make a decision that actually benefits your dog’s oral health. If you are still looking for the right dog to share your life with, our adoption page is a good place to start — and once you bring a dog home, dental care should be near the top of your list.

Do Dental Chews for Dogs Actually Work?

Yes — but with caveats. Dental chews can reduce plaque and tartar buildup when used consistently as part of a broader oral hygiene routine. The mechanical action of chewing is the primary benefit. As your dog gnaws on a textured chew, the surface scrapes against the teeth, physically removing soft plaque before it mineralizes into tartar. Some chews also contain active ingredients — like sodium hexametaphosphate or zinc sulfate — that chemically inhibit tartar formation.

Studies have shown that certain dental chews can reduce plaque by 15 to 70 percent and tartar by 10 to 60 percent, depending on the product and the study design. Those are meaningful numbers, but they come with an important qualifier: dental chews are most effective on the teeth that actually make contact with the chew. The front incisors, the inner surfaces of teeth, and areas along the gum line often receive minimal benefit because the chew never reaches them.

Think of dental chews as one tool in the toolbox, not the entire toolbox. They are not a replacement for professional veterinary cleanings, and they work best alongside other oral care practices like brushing. That said, for dogs who will not tolerate a toothbrush — and there are many — a well-chosen dental chew is far better than nothing at all.

The VOHC Seal of Acceptance: What It Means and Why It Matters

If you want to cut through the marketing noise, the Veterinary Oral Health Council (VOHC) Seal of Acceptance is the single most reliable indicator that a dental chew actually works. The VOHC is an independent organization that reviews clinical trial data submitted by manufacturers. To earn the seal, a product must demonstrate in controlled studies that it reduces plaque or tartar by a statistically significant amount compared to a control group.

Not every effective product carries the seal — the review process is voluntary and involves cost, so some smaller brands skip it — but any product that does carry the seal has been independently verified. When you see the VOHC seal on a package of dental chews for dogs, you can be reasonably confident that the product does what it claims.

Products without the seal are not necessarily ineffective, but you are relying on the manufacturer’s word rather than third-party verification. If you are spending money specifically to improve your dog’s dental health, the VOHC seal is worth seeking out.

How Dental Chews Clean a Dog’s Teeth

Dental chews work through two primary mechanisms, and understanding both helps explain why some products outperform others.

Mechanical abrasion. This is the most straightforward mechanism. As your dog chews, the texture of the product rubs against the tooth surface, physically scraping away the soft biofilm of plaque. The longer and more thoroughly the dog chews, the more plaque gets removed. This is why texture matters — ridged, grooved, or fibrous chews tend to outperform smooth ones. A chew that your dog swallows in thirty seconds provides almost no dental benefit, regardless of what is printed on the label.

Chemical action. Some dental chews incorporate ingredients that interfere with the mineralization of plaque into tartar. Sodium hexametaphosphate is one of the most common and well-studied of these ingredients. It binds calcium in saliva, which slows the hardening process. Other chews use enzymes or antimicrobial agents that reduce the bacterial load in the mouth. These chemical ingredients extend the benefit beyond just the surfaces the chew physically touches.

The ideal dental chew combines both mechanisms: a texture that encourages prolonged chewing and active ingredients that work on a chemical level. Chews that rely on only one mechanism still help, but the combination is more effective.

Best Types of Dental Chews for Dogs

The market for dental chews is enormous, and the options can be overwhelming. Here are the main categories worth considering, along with what each one does well and where it falls short.

Enzyme-coated chews. These chews contain enzymes that help break down bacterial plaque. They tend to be moderately firm and designed to encourage chewing rather than quick consumption. Many VOHC-approved products fall into this category. They are a solid everyday choice for most dogs.

Textured dental sticks. These are the products you see most often in grocery and pet store aisles — elongated sticks with ridges, bumps, or grooves. The texture does the heavy lifting. Quality varies enormously in this category, so look for products with the VOHC seal or those that use active tartar-fighting ingredients in addition to their textured design.

Raw or natural chews. Bully sticks, tendons, and certain dried animal parts provide significant chewing time, which translates to more mechanical plaque removal. They lack the chemical tartar-fighting agents of engineered dental chews, but the extended chewing duration can compensate. Choose single-ingredient options with no additives whenever possible.

Dental-specific rawhide alternatives. Traditional rawhide has fallen out of favor due to digestive and choking risks. Newer alternatives made from sweet potato, vegetable starch, or collagen are designed to mimic the chewing experience with better digestibility. Some are formulated with dental-health ingredients and carry the VOHC seal.

Rubber chew toys with treat compartments. While not technically “dental chews,” durable rubber toys that you can fill with paste or treats encourage prolonged chewing and physical abrasion against teeth. They are reusable, long-lasting, and can be a cost-effective part of a dental care routine, though they lack the chemical benefits of purpose-made dental chews.

Safety Considerations for Dental Chews

Dental chews are generally safe, but they are not risk-free. A few precautions go a long way.

Choking hazards. This is the most serious risk. Dogs that gulp food or try to swallow large pieces without chewing properly can choke on dental chews, especially if the chew is too small for the dog. Always supervise your dog when they have a dental chew, particularly the first few times you offer a new product. Remove any piece that has been chewed small enough to swallow whole.

Digestive blockages. Some dental chews — particularly those made with rawhide or very dense materials — can cause gastrointestinal obstruction if swallowed in large chunks. This is a veterinary emergency. Choose products that are designed to break down in the digestive tract, and avoid any chew that your dog tends to break into large, hard fragments.

Calorie content. Dental chews are food, and they contain calories. Some of the larger chews pack 70 to 100 calories or more per piece. For a small dog eating 400 calories a day, a single dental chew could represent a quarter of their daily intake. Factor dental chews into your dog’s total daily calorie count to prevent weight gain, which brings its own set of health problems.

Tooth fractures. Chews that are too hard — harder than the tooth itself — can crack or fracture teeth. A good rule of thumb is the “thumbnail test”: if you cannot make a dent in the chew with your thumbnail, it may be too hard for your dog’s teeth. Antlers, bones, and hooves are the most common culprits for tooth fractures and are generally not recommended by veterinary dentists.

Allergies and sensitivities. Dogs with food sensitivities or allergies may react to ingredients in dental chews. Common allergens include chicken, beef, wheat, soy, and corn. Read ingredient labels carefully, especially if your dog has a known sensitivity. Limited-ingredient and grain-free dental chews are available for dogs with dietary restrictions.

Size Matching: Choosing the Right Dental Chew for Your Dog

Getting the size right is not a minor detail — it is arguably the most important safety consideration when selecting dental chews for dogs. A chew that is too small is a choking hazard. A chew that is too large may be too hard for a small dog to work effectively, and they may give up before getting any dental benefit.

Follow the manufacturer’s weight guidelines. Most dental chew brands provide clear weight-based sizing on their packaging. These guidelines exist for a reason. If your dog is 45 pounds and the product offers a medium (25–50 lbs) and a large (50–75 lbs), go with the medium. When in doubt, size up rather than down — a slightly oversized chew is safer than one your dog can swallow.

Consider your dog’s chewing style. Some dogs are patient, methodical chewers. Others are aggressive power chewers who can demolish a product in minutes. If your dog is a fast, aggressive chewer, you may need to select a more durable product or a larger size than their weight alone would suggest. The goal is a chew that lasts at least five to ten minutes of active chewing — anything less provides minimal dental benefit.

Watch jaw strength, not just body weight. Some breeds have disproportionately strong jaws relative to their size. Pit bulls, Staffordshire terriers, and similar breeds in the 40-to-60-pound range may need chews rated for larger dogs. Conversely, brachycephalic breeds like bulldogs and pugs have unusual jaw structures that can make certain chew shapes difficult to hold and work effectively.

How Often Should You Give Your Dog a Dental Chew?

Most veterinarians and product manufacturers recommend one dental chew per day for optimal results. Daily use provides the most consistent plaque control because plaque begins forming on teeth within hours of being removed. Waiting several days between chews allows plaque to accumulate and harden into tartar, which chews alone cannot remove.

That said, daily dental chews are not mandatory, and for some dogs they may not be appropriate. Here are a few guidelines:

• Daily: Ideal for dogs with a history of dental problems, breeds predisposed to periodontal disease, or dogs who will not tolerate tooth brushing.
• Three to five times per week: A reasonable frequency for most healthy adult dogs. Provides meaningful plaque reduction without excessive calorie intake.
• Occasionally: Better than nothing, but do not expect significant dental benefits from a chew given once or twice a week.

Regardless of frequency, dental chews should always be given after meals rather than on an empty stomach. This reduces the risk of digestive upset and ensures the chew is working on freshly formed plaque rather than an already-coated tooth surface.

Dental Chews vs. Brushing: Which Is Better?

Brushing wins. There is no getting around this. Tooth brushing with a dog-specific toothpaste remains the gold standard for canine dental care because it allows you to clean every surface of every tooth, including the inner surfaces and the gum line — areas that dental chews rarely reach. Veterinary dentists consistently rank brushing as the single most effective thing an owner can do for their dog’s oral health at home.

But here is the reality: most dog owners do not brush their dog’s teeth regularly. Surveys suggest that fewer than five percent of dog owners brush their dog’s teeth daily, and a significant percentage never brush at all. Dogs can be uncooperative. Owners are busy. The toothbrush sits in a drawer unused.

This is where dental chews earn their value. They are easy. You hand your dog a chew, and the dog does the work. There is no struggle, no resistance, and no special technique required. For the vast majority of dog owners who are not going to brush consistently, a daily dental chew provides a level of plaque control that is meaningfully better than doing nothing.

The ideal approach combines both: brush when you can, and offer a dental chew on the days you do not brush. If your dog absolutely will not tolerate brushing, daily dental chews combined with annual professional cleanings represent a reasonable alternative. Neither approach eliminates the need for regular veterinary dental checkups.

Ingredients to Avoid in Dental Chews

Not all dental chews are created equal, and some contain ingredients that are worth avoiding. Here is what to watch for on the label.

Artificial colors and dyes. Dental chews do not need to be green, blue, or any other particular color. Artificial dyes like Red 40, Yellow 5, and Blue 2 serve no functional purpose and are unnecessary additives. Some dogs are sensitive to synthetic dyes, and there is no benefit to including them.

BHA and BHT. These synthetic preservatives appear in some pet products and have raised concerns in toxicology research. While the amounts in any single dental chew are small, daily exposure over a lifetime adds up. Many quality brands have moved away from BHA and BHT in favor of natural preservatives like mixed tocopherols (vitamin E).

Excessive sugar or sweeteners. Some dental chews contain added sugars to improve palatability. This is counterproductive for a product designed to improve dental health. Sugar feeds the oral bacteria that cause plaque formation in the first place. Xylitol, while safe for human dental products, is extremely toxic to dogs and should never appear in any canine product — always check labels.

Unidentified meat by-products. Vague ingredient descriptions like “animal by-products” or “meat meal” tell you nothing about the protein source and may indicate lower-quality ingredients. Look for named protein sources — “chicken” rather than “poultry by-product” — so you know what your dog is eating, particularly if they have food sensitivities.

Propylene glycol. Used as a humectant to keep chews moist, propylene glycol is generally recognized as safe in small amounts but offers no benefit to your dog. Higher-quality dental chews avoid it entirely.

High sodium content. Some dental chews contain more salt than necessary. While sodium hexametaphosphate is a beneficial tartar-fighting ingredient, excessive added salt beyond what is needed for that function can contribute to increased thirst and, in dogs with heart or kidney issues, may be problematic.

Best Dental Chews for Puppies

Puppies have unique dental needs. They begin teething around three to four months of age, and their baby teeth are replaced by adult teeth between four and seven months. During this period, their teeth and gums are more sensitive, and their jaws are not yet strong enough for adult-sized dental chews.

For puppies, look for dental chews that are specifically labeled for puppies or young dogs. These products are softer, smaller, and designed to be gentle on developing teeth and gums. Many puppy dental chews also provide the satisfying chewing experience that teething puppies crave, which can redirect their chewing away from your shoes and furniture.

Avoid giving puppies any hard dental chew designed for adult dogs. Their baby teeth are more fragile and more susceptible to fractures. Wait until your puppy has their full set of adult teeth — typically around seven months — before transitioning to standard adult dental chews. Even then, start with the smallest appropriate size and monitor closely.

Puppy dental chews can be introduced as early as eight to twelve weeks, depending on the product. Start with short chewing sessions and always supervise. If you have recently adopted a puppy through our adoption program, your veterinarian can recommend the best dental care products for your new companion’s age and size.

Best Dental Chews for Senior Dogs

Senior dogs present the opposite challenge from puppies. Years of wear, possible tooth loss, gum recession, and the potential for underlying periodontal disease mean that older dogs often need gentler dental chews than they used in their prime.

For senior dogs, prioritize dental chews that are softer and easier to work. Many brands offer “senior” or “gentle” formulations that are designed to provide dental benefits without placing excessive stress on aging teeth and weakened gums. Chews that become pliable when moistened by saliva are particularly good choices because they conform to the tooth surface and reduce the risk of fractures.

Senior dogs with missing teeth or advanced dental disease may not be able to use traditional dental chews at all. In these cases, dental water additives, dental wipes, or soft enzymatic chews may be better alternatives. Always consult your veterinarian before starting any dental product for a senior dog, especially if they have not had a recent dental examination.

It is also worth noting that dental disease is extremely common in older dogs — some studies suggest that more than 80 percent of dogs over the age of three have some degree of periodontal disease. Starting dental chews earlier in life, while a dog’s teeth are still healthy, provides the most long-term benefit.

Best Dental Chews for Heavy Chewers

Heavy chewers — the dogs who can demolish a standard dental chew in under a minute — need products designed for durability. A dental chew that disappears in seconds provides almost no plaque-removing benefit, and a dog that swallows large pieces quickly is at higher risk for choking and digestive issues.

For aggressive chewers, look for dental chews with the following characteristics:

• Dense, firm texture: Products specifically labeled for “strong chewers” or “power chewers” are formulated to last longer. They are denser and more resistant to being broken apart quickly.
• Larger sizes: Size up from the manufacturer’s weight recommendation. A chew that a heavy chewer has to work at from different angles provides more chewing time and more tooth contact.
• Textured surfaces: Deep ridges and nubs slow the chewing process and increase the abrasive contact with tooth surfaces. Smooth chews get consumed too quickly by determined chewers.
• Combination products: Some brands embed a harder core within a softer outer layer, giving power chewers a reason to keep working at the product after the outer layer is gone.

Even with durable dental chews, always supervise heavy chewers. These are often the dogs most likely to break off and swallow large chunks, and they benefit the most from your watchful eye. If your dog consistently destroys every dental chew in under two minutes, consider supplementing with a durable rubber chew toy that provides ongoing mechanical cleaning between dental chew sessions.

Frequently Asked Questions

Can dental chews replace professional teeth cleaning?

No. Dental chews reduce plaque and tartar buildup, but they cannot address existing tartar below the gum line, treat periodontal disease, or replace the thorough cleaning and examination that a veterinarian performs under anesthesia. Think of dental chews as daily maintenance — similar to brushing your own teeth — while professional cleanings are the deep clean that catches what daily care misses. Most veterinarians recommend professional dental cleanings annually or as needed based on your dog’s oral health.

Are dental chews safe for dogs with sensitive stomachs?

Most dental chews are well-tolerated, but dogs with sensitive stomachs may experience loose stools, gas, or vomiting when trying a new product. Start with half a chew and observe how your dog responds over 24 to 48 hours before offering a full serving. Limited-ingredient dental chews — those with short, simple ingredient lists — are generally the safest bet for sensitive dogs. If your dog has a diagnosed gastrointestinal condition, consult your veterinarian before introducing any new dental product.

How long should a dental chew last?

A dental chew should ideally last at least five to ten minutes of active chewing. Anything less than five minutes provides minimal dental benefit because there is not enough sustained contact between the chew and the tooth surfaces. If your dog consistently finishes a dental chew in under two minutes, you may need to size up, switch to a denser product, or choose a chew specifically designed for aggressive chewers. Chews that last longer than 20 to 30 minutes may be too hard and could pose a risk for tooth fractures.

Can I give my dog more than one dental chew per day?

It is generally not recommended. Most dental chews are designed as a once-daily product, and giving more than one increases calorie intake without a proportional increase in dental benefit. The first chew of the day removes the majority of accessible plaque; a second chew has diminishing returns. If you feel one chew is not providing enough benefit, focus on improving other aspects of your dog’s dental care — brushing, dental water additives, or scheduling a professional cleaning — rather than doubling up on chews.

What age can puppies start having dental chews?

Most puppy-specific dental chews can be introduced between eight and twelve weeks of age, depending on the brand. Always choose products explicitly labeled for puppies, as these are softer and appropriately sized. Standard adult dental chews should not be given until your puppy has their full set of permanent teeth, which typically happens around six to seven months of age. When in doubt, ask your veterinarian at your puppy’s next wellness visit.

Do dental chews help with bad breath in dogs?

They can, but it depends on the cause. If your dog’s bad breath is caused by plaque and mild tartar buildup — which is the most common cause — dental chews can meaningfully improve it by reducing the bacterial load in the mouth. However, persistent or severe bad breath can indicate periodontal disease, gastrointestinal issues, kidney disease, or other health problems that dental chews alone will not fix. If your dog’s breath remains noticeably foul despite regular dental chews and good oral hygiene, a veterinary examination is warranted.

Are grain-free dental chews better for dogs?

Not necessarily. Grain-free dental chews are important for dogs with confirmed grain allergies or sensitivities, but for the average dog, there is no evidence that grain-free formulations provide superior dental or overall health benefits. The presence or absence of grains matters far less than the overall quality of ingredients, the texture of the chew, and whether the product has been verified by the VOHC. Choose based on your individual dog’s dietary needs rather than broad marketing trends.
