Do Dental Chews and Water Additives Work for Dogs?

Dog dental health is one of the most overlooked parts of wellness, yet poor oral hygiene can lead to gum disease, pain, infection, and costly vet bills. Many dog parents reach for dental chews or water additives as a simple solution—but do they really work?

Many pet owners turn to pet dental products, such as chews and water additives, to address oral bacteria and improve their dog's dental health.

The short answer: yes, they help—when you choose the right products and use them consistently, especially those pet dental products that are VOHC-certified for proven effectiveness. But they’re only one part of a full dental-care routine.

Let’s break down what you need to know so you can make confident, informed choices for your dog’s oral health.

Do Dental Chews Really Help Clean Dogs' Teeth?

Dental chews are one of the most popular oral-care tools for dogs. They’re marketed to reduce tartar, freshen breath, and support gum health.

• Dog dental chews work by mechanically cleaning the dog's mouth as your pet chews, helping to reduce plaque buildup and prevent tartar buildup on the teeth.

• The texture and design of dog dental chews can disrupt plaque formation, helping to maintain a healthier dog's mouth.

• Some dog dental chews are formulated with ingredients that provide digestive support in addition to oral health benefits.

So how effective are they?

Benefits of Dental Chews

• Mechanical cleaning: The chewing motion helps scrape soft plaque off teeth.

• Increased saliva production: Saliva helps naturally flush bacteria.

• Breath freshening: Many chews contain ingredients that temporarily improve odor.

• Mental stimulation: Chews keep dogs busy and satisfied.

Limitations of Dental Chews

• They cannot remove hardened tartar.

• Chewing alone won't clean the gumline, where most dental disease begins.

• Some treats are high in calories or made with artificial ingredients.

• Dogs that swallow chews quickly won’t get the cleaning benefit.

What to Look for in a Quality Dental Chew

• Size-appropriate for your dog

• Long-lasting enough to encourage chewing

• Vet-approved or VOHC-certified

• Limited-ingredient formulas if your dog has sensitivities

Dental chews can be a valuable tool—but they aren’t a full solution on their own.

Do Water Additives Work for Dog Dental Health?

Water additives are an easy way to support fresher breath and cleaner mouths. Dental water additives and dog water additives offer a convenient option for supporting oral health, especially for pets that resist brushing.

Just add the recommended amount to your dog’s daily water bowl. Certain dental water additives contain antibacterial agents like chlorine dioxide or stabilized chlorine dioxide, which help control plaque, reduce harmful bacteria, and limit bacterial growth. Unlike brushing, water additives can reach areas in the mouth that are difficult to clean manually. When choosing a product, look for dental water additives safe for long-term use, and monitor your dog for any allergic reactions such as itching or swelling. While water additives may help slow plaque accumulation, they cannot fully replace the benefits of mechanical cleaning.

Benefits of Water Additives

• Convenient: Ideal for busy pet parents

• Target bacteria: Many formulas help reduce the bacteria that cause plaque

• Breath improvement: They often help with odor quickly

• Great for dogs who resist brushing

Limitations of Water Additives

• They don’t scrub or mechanically clean teeth

• They are a supportive tool—not a replacement for brushing

• Some formulas contain artificial sweeteners or unnecessary additives

Water additives can help, especially when combined with other habits, but they shouldn’t be your only dental-care strategy.

Safety Considerations for Dental Chews and Water Additives

When it comes to maintaining your dog’s oral health, safety should always come first. Dental chews and water additives can be great allies in the fight against plaque and tartar buildup, but it’s important for pet parents to choose and use these products wisely.

Dental Chews: Not all dental chews are created equal. Always select chews that are the right size and hardness for your dog’s breed and chewing style to prevent choking or tooth fractures. Look for products made with high-quality, natural ingredients and avoid chews with artificial colors, flavors, or preservatives. If your dog has food sensitivities or allergies, check the ingredient list carefully. Supervise your dog while they enjoy their chew to ensure they don’t swallow large pieces, which could lead to digestive issues or blockages.

Water Additives:When choosing water additives, opt for formulas specifically designed for dogs and approved by veterinarians. Some additives may contain ingredients that aren’t suitable for all pets, so always read the label and follow the recommended dosage. If your dog has a sensitive stomach or underlying health conditions, consult your vet before introducing a new product. Monitor your dog for any changes in behavior, appetite, or water consumption after adding an additive to their bowl.

The Most Effective Approach: A Complete At-Home Dog Dental Routine

Chews and additives are helpful, but real results come from consistent daily care. Combining multiple dental care methods—such as water additives, dental powders, dental treats, and dog safe toothpaste—can significantly improve oral health. Using other dental care methods alongside regular brushing and professional dental cleaning creates a comprehensive approach to maintaining your pet’s teeth and gums.

Ideally, your dog’s routine should include:

1. A Daily Dental Supplement

Products like Daily Dental from Houndswell are designed to support oral hygiene daily with science-backed ingredients that help target bacteria, plaque, and odor at the source.

3. Water Additives (daily)

Great for dogs who struggle with brushing or need breath support.

4. Professional Cleanings

Your veterinarian or groomer can identify issues early and perform deeper cleaning when needed.

5. Routine Hygiene Visits

Regular hygiene helps spot dental concerns before they become bigger problems.

So, Do Dental Chews and Water Additives Work?

Yes—dental chews and water additives absolutely work, but only as part of a bigger picture.

They help reduce plaque, improve breath, and support oral health, but they can’t replace brushing, dental supplements, or professional care. When used consistently and paired with a balanced routine, they’re valuable tools for keeping your dog healthier and happier.

Consistency is where the real magic happens.
