Dental sticks and chews are one of the most popular ways owners try to keep their dog’s teeth clean, but do they actually remove tartar, or is that just clever marketing? The honest answer is nuanced: the right dental chews can meaningfully reduce plaque and slow tartar buildup, but no chew removes hardened tartar that has already formed. Understanding that difference is the key to using them effectively and knowing when your dog still needs a professional clean.

Do Dental Sticks Actually Work?
Yes, but with limits. Effective dental chews work in two ways: mechanically, as the chewing action scrapes soft plaque off the tooth surface, and sometimes chemically, through added enzymes or ingredients that inhibit plaque-forming bacteria. Studies and veterinary dental organizations confirm that certain chews reduce plaque and tartar accumulation when used daily. What they cannot do is remove tartar (also called calculus) once it has hardened onto the tooth. At that point only a professional scaling by a veterinarian will remove it.

Think of dental chews as prevention, not repair. Used daily they slow the rate at which soft plaque turns into hard tartar, freshen breath, and reduce the frequency of professional cleanings needed. They will not reverse existing tartar, cure gum disease, or replace brushing entirely. If your dog already has visible brown or yellow buildup along the gumline, a vet check and likely a cleaning is the starting point, after which chews help keep teeth cleaner for longer.
How to Choose an Effective Dental Chew
Look for the VOHC Seal
The Veterinary Oral Health Council (VOHC) awards a seal to products proven to reduce plaque or tartar. Choosing a VOHC-accepted chew is the single most reliable way to know a product actually works rather than just claiming to.
Match the Size and Texture to Your Dog
The chew should be sized for your dog’s weight so it lasts long enough to clean, and firm enough to encourage real chewing without being so hard it risks a cracked tooth. Avoid extremely hard chews for dogs with dental issues.
Consider Ingredients for Sensitive Dogs
Senior dogs and those with sensitive stomachs do better with easily digestible, limited-ingredient chews. Look for options free of common irritants and, for weight-conscious dogs, lower-calorie formulas.

Getting the Most From Dental Chews
Give a dental chew once daily as part of a routine, ideally combined with regular tooth brushing, which remains the gold standard. Supervise chewing, choose the correct size, and count the chew toward your dog’s daily calories to avoid weight gain. For senior dogs with sensitive stomachs, introduce a new chew gradually and pick a gentle, digestible formula. Even the best chew is a complement to, not a replacement for, brushing and veterinary check-ups.
Signs Your Dog Needs More Than Dental Chews
Dental chews are prevention, so watch for signs that your dog needs professional care instead. Persistent bad breath, yellow-brown crust along the gumline, red or bleeding gums, drooling, pawing at the mouth, or reluctance to eat hard food all point to tartar and possible gum disease that chews cannot fix. At that stage a veterinary dental exam and cleaning is the right step; once the teeth are clean, daily chews and brushing keep them that way for far longer.
Dental Chews vs Water Additives vs Brushing
Each at-home method plays a role. Brushing with dog toothpaste is the most effective and removes plaque directly, but many dogs resist it. Dental chews are the easiest to keep up daily and add a useful mechanical clean, which is why compliance with them is often higher. Water additives are the most hands-off, reducing bacteria across the whole mouth, though they are the gentlest option. The strongest routine combines all three where possible: brush when you can, give a VOHC chew daily, and use an additive for extra coverage, backed by regular veterinary check-ups.
The Bottom Line on Dental Sticks
Dental sticks are a genuinely useful tool for slowing plaque and tartar buildup and freshening breath, but they are prevention, not a cure for tartar that has already hardened. Choose a VOHC-accepted chew sized correctly for your dog, give one daily, and pair it with brushing and routine veterinary check-ups. Used that way, a good dental chew helps your dog keep cleaner, healthier teeth and can stretch the time between professional cleanings.
Frequently Asked Questions
Can you fix tartar buildup on dogs with dental sticks?
Dental sticks cannot remove tartar that has already hardened on the teeth; only a professional veterinary cleaning can do that. What quality dental chews do is slow the formation of new tartar by removing soft plaque before it mineralizes, so they are prevention rather than a fix for existing buildup.
What are the best dental sticks for a senior dog with a sensitive stomach?
Choose a VOHC-accepted chew that is easily digestible and limited in ingredients, and introduce it slowly. Softer, natural options like Whimzees or vet-recommended VeggieDent tend to suit sensitive stomachs better than very hard chews, and sizing the chew correctly for your dog reduces digestive upset.
How long do dental chews take to work?
Because they work by preventing new plaque and tartar, you will not see hardened tartar disappear. With daily use you may notice fresher breath within days and reduced new buildup over weeks. Consistent daily use combined with brushing gives the best results.
Are dental sticks a substitute for brushing?
No. Brushing is the most effective at-home dental care, and dental chews are a helpful complement, not a replacement. Using both daily, plus regular veterinary check-ups, keeps a dog’s teeth healthiest.
Can dental chews reduce tartar in dogs at all?
Yes, VOHC-accepted dental chews are proven to reduce the accumulation of plaque and tartar when used daily, by mechanically scraping soft plaque and sometimes using enzymes to slow bacteria. They reduce buildup going forward but do not remove existing hardened tartar.
