    Drinking Water Additive Decreases Plaque and Calculus Accumulation in Cats


    David E. Clarke, BVSc, MACVSc



    This study was performed to determine the effect of a drinking water additive on reducing plaque and calculus accumulation in cats. A two-period, parallel crossover design was used with each period consisting of a 56-day test phase. Results demonstrated that the addition of xylitol to the drinking water was effective in reducing plaque and calculus accumulation in cats.

            Periodontal disease is diagnosed commonly in companion animal practice in adult cats. There is a direct relationship between the development of periodontal disease, in particular gingivitis, and accumulation of dental plaque on the tooth surface. Gingivitis is reversible and can be prevented thorough plaque removal by the veterinarian and control by the cat owner. Plaque control continues to be the most effective and widely employed oral hygiene method in humans. However, tooth brushing may be technically difficult for many cat owners, resulting in low compliance and ineffective plaque removal. The use of a drinking water additive may improve oral health in cats. The purpose of the study reported here was to evaluate the reduction in plaque and calculus accumulation using a commercially available drinking water additive containing xylitol.


    Materials and Methods

            Adult male and female domestic shorthair cats (n = 30), ranting in an age from 2 to 14-years, were initially used in this study. The cats were considered in good health based on physical examination and the results of laboratory tests (full hematology examination, biochemistry analysis, urinalysis). The eats were privately owned by two clients and were housed at their individual homes throughout the study period. The study was performed in accordance with guidelines proposed by the Veterinary Oral Health Council (VOHC).

            The study was conducted as a two-period, parallel crossover trial. Each study period consisted of a 56-day test phase. The cats were gouped into two blocks based on their housing arrangements. The cats in the first group received Eukanuba adult chicken and rice dry biscuits and fresh untreated water each day during the initial test phase. The cats in the second group received the same biscuits, but had access to fresh drinking water treated with xylitol at 0.005% each day. Drinking water was supplied from the owner’s household source located in Melborne, Australia and supplied ad libitum thought the study period. Biscuits were fed to each cat based on calculated body weight and basal requirements. No other food or dental hygiene products where provided during the study period.

            Cats received professional teeth cleaning (including supra- and subgigvival scaling) and tooth polishing at the start of each test phase to ensure the absence of plaque and calculus on tooth surfaces and to insure all cats started each test phase at the same oral health baseline. All cats were anesthetized for teeth cleaning, as well as for plaque and calculus evaluations, which were performed at the end of each test phase. At the initial evaluation, assessment of periodontal probing depth (PDD) and probing attachment level (PAL) demonstrated that periodontal disease was absent. All cats had full dentition and did not have grossly visable dental resorptive lesions. For all teeth scored, the PPD did not exceed 0.5-mm and there was no attachment loss using the comentoenamel junction as a reference point.

            Oral examination and professional teeth cleaning were performed following the administration of a general anesthetic. Cats received interavenous Hartmanns solution via a cephalic catheter; permediction using a combination of buprenorphine (0.008 mg/kg SQ), acepromazine (0.05 mg/kg SQ), and Glycopyrrolate (0.01 mg/kg IV) and diazepam (0.25 mg/kg IV); followed by maintenance with isoflurane in oxygen via an including the maxillary canine, and third and fourth premolar teeth; and, mandibular canine third and fourth premolar, and first molar teeth bilaterally.

            During the second test phase, cat #19 escaped out of the front door of the owner’s house and was subsequently involved in a car accident, which resulted in the cat’s death. The mean tooth scores (Table 1) and total mouth mean scores (Table 2), which involve the statistical comparisons, do not include data from cat #19.

            The final results were recorded using 29 cats. Each of the 29 cats were involved in both 56-day test phaases, and therefore each cat had access to the untreated water during one test phase and water treated with the additive during the other test phase. This study design allowed each cat to act as its own control.

            One-way analysis of variance (ANOVA) was used to compare the test regimes for differences in the plaque and calculus measurements. Comparisons between the individual group mean sources for plaque and calculus were performed using Tuke’s multiple comparisons test. A value of P < 0.05 was considered significant.

            Plaque scores were determined based on visual assessment of plaque thickness and surface area coverage (%) on the buccal or labial crown surface aided by the application of a 2 % eosin disclosing solution. The same examiner graded plaque accumulation thought the test phases. Graded criteria for plaque cover: 0 = no detected; 1 = < 25 %; 2 = 25 – 50 %; 3 = 50 – 75 %; 4 = 75 – 100%. Grading criteria for plaque accumulation through the test phases. Grading criteria for plaque thickens: 1 = light; 2 = medium; 3 = 3 heavy. The buccal tooth surface was divided into gingival and coronal halves. Each tooth was surface was divided into gingival and coronal halves. Each tooth half was scored for plaque coverage and thickness. The coverage score was multiplied by the thickness score to obtain a gingival and coronal plaque scores for each tooth were added to obtain a total tooth score for each tooth. The oral mouth score was obtained by adding all 14 individual total mouth score by 14.

            Calculus scores were determined based on visual assessment of calculus thickness and surface area coverage (%) on the buccal or labial crown surface. The disclosing solution was removed from the tooth surface with a toothbrush, followed by rinsing with water and air drying. The same examiner graded calculus accumulation through the test phases. Grading criteria for calculus coverage: 0 = no calculus detected; 1 = < 25%; 2 = 25 – 50 %; 3 = 50 – 75 %; 4 = 75 – 100%. Grading criteria for plaque thickens: 1 = light; 2 = medium; 3 = 3 heavy. The coverage score was multiplied by the thickness score to obtain a mesial and distal score for each half of the tooth. The mesial and distal calculus scores for each tooth were added to obtain a total tooth score for each tooth. The total mouth score was obtained by adding all 14 individual total tooth scores. The total mean tooth score was obtained by dividing the total mouth score by 14.



            All cats accepted and readily drank the treated water. When cats had access to the treated water, each individual cat as well as the whole group had significantly for less plaque and calculus accumulations than when they had access to untreated water (Table 1). For cats drinking untreated water, the mean tooth plaque score of 5.1 +/- 1.4 when drinking treated water. Plaque accumulation decreased by 52.3 % when drinking treated water. For cats drinking untreated water, the mean tooth calculus score was 4.2 +/- 1.9 compared with a mean tooth calculus score of 2.0 +/- 0.8 when drinking treated water. Calculus accumulation descred by 53.5 % when drinking treated water (Table 2).



            Periodontal disease is a significant disease in client-owned domestic breed cats, as plaque rapidly forms on teeth when no oral hygiene is performed. Although there have been a number of studies demonstrating the plaque reducing abilities of tooth brushing in the dog, there are few studies that have been performed in the cat. In companion animal practice, it is difficult to convince clients to brush their clients teeth, and moreover, the majority of cats resist having their teeth cleaned with a toothbrush. For these reasons, the compliance of toothbrushing in client-owned cats is generally low. Therefore, the use of an effective method that also has positive owner compliane is especially warranted in the cat. The results reported here demonstrate that drinking water additive improves oral health in the cat.

            Xylitol is a five-carbon natural sugar alchol or pentitol, which has been shown to have both an antibacterial effect on oral bacteria and dental plaque, as well as anti-calculus forming properties. The non-fermentability or very low fermentability of xylitol by dental plaque leads to a number of consequential phenomena of possible significance that include: update by bacteria and inhibition of bacterial growth; formation of soluble extracellular polysaccarides that make plaque less adhesive to the tooth surface; and, inhibition of spontaneous perception of calcium phosphate, decreasing the formation and accumulation of dental calculus.

            The antibacterial properties and the xylitol metabolism of dental plaque may be interpreted by understanding that dental plaque contains bacteria. The bacteria, via the fructose phosphotransferase system, take up xylitol. Xylitol is metabolized into xylitol-5-phosphate inhibits glycolysis and the uptake of glucose in the cell, which results in inhabitation of bacterial growth.

            It is generally accepted that chewing xylitol sweetened gum after meals may reduce plaque formation and gingival inflammation in humans. The results of two 12-month clinical studies showed that xylitol significantly reduced dental plaque when incorporated into chewing gum or a dental snack. Subjects in these studies also had less inflammation of the periodontal tissues. In another study, the daily use of a xylitol –containing chewing gum in humans reduced the weight of plaque formed in comparison to when no chewing gum was used. In these trials, the inability of chewing gum was used. In the trails, the inability of chewing gum per se to remove plaque from the tooth surfaces indicated that the decrease in plaque formation when using a xylitol-containing product was due to the chemical activity of xylitol.

            Microbiological studies add validity to these observations. A significant reduction in Streptococcus mutans, in both plaque and saliva compared with pre-treatment values, has been reported in humans chewing xylitol gums for 4-weeks. Streptococcus mutans after 2-months of chewing xylitol-containing gum. In general, xylitol has been shown to reduce the bacterial growth rate.

            The xylitol molecule also has the ability to form complexes with certain cations, such as Ca, Cu and Fe, based on its polyol properties. The habitual consumption of xylitol has shown that it not only concentrates calcium in plaque, but also keeps calcium ions in a soluble form, reducing calculus accumulation on the tooth surface.

            In the study presented here, the daily addition of xylitol to the drinking water of cats significantly reduced the accumulation of plaque and calculus following professional teeth cleaning (subra- and subgingival scaling and polishing). The results of this study showed that cats drinking water treated with xylitol had approximately half the plaque and calculus accumulation compared to when they were drinking untreated water. Xylitol is a useful adjunct in maintaining the oral health of cats during the period between professional teeth cleaning procedures.

    Excellent product by karolanne from Montreal, Quebec, Canada10/02/2013

    Excellent product. My dogs like it. They continue to drink like usual and her teeth looks great. I combine with the gel and 1 brushing per week.

    Hope it helps! by Marilyn from St. Louis03/01/2013

    I ordered two of these as my vet suggested it after we had our dog's teeth cleaned. It's easy to use and I think once again is helping with the breathe problem. The vet says anything to help keep the teeth from getting a build up will help. Guess I will see at the end of the year if it did. I am going to do it for the year to see.

    No longer skeptical! by LeeP06/17/2013

    So even as I was ordering this I didn't really think it would work. It has! Frisco's breath is much better and he already has reduced tartar on his teeth. I am a believer.

    Has Xylitol in it by Shel01/17/2012

    Xylitol is famously toxic to dogs. No dog owner should use this

    Works Great by maggiemae from Belgium, WI10/26/2011

    Our vet had recommended a water additive to help fight plaque and bad breath after we had our dog's teeth professionally cleaned. We started using this product just a few days after the cleaning and have noticed that our dog still has fresh breath. She seems to like the additive and still drinks her water as usual.

    It certainly helps! by ekcpeterson from Atlanta, GA10/22/2012

    I definitely noticed a difference for my dog.

    Poisonous to Dogs!! by sbennette from Painted Post, NY02/10/2010

    This product is poisonous to dogs as it contains Xylitol. Considering the fact that dogs may drink it on a daily basis is very concerning.

    Breathalyser PLUS Water Additive (500 mL) by Re from Raleigh, NC05/30/2012

    This product works well to protect your pet's teeth and gums and it helps with bad breath. I would recommend it to anyone that has the same problem I have, in that I cannot brush my dogs teeth. Too old, too tired!

    Not recommended by southstar from FLorida10/25/2011

    Wasted money, and at this time money is precious. Dog would not drink this in the water even when recommended amount put into water was decreased.

    IT WORKS! by Marty03/22/2011

    I bought this to try as my dog has real bad breath, teeth are fine, eats nothing but the best grain free dog food. so i said WTH i will try it,, in 1 day my dogs breath was just perfect, all my friends checked out her breath and all agreed it works, i just put 2 capfuls a day, as i have Rottis and they drinks lots of water. Buy it ,, IT WORKS

    Breathalyser PLUS by K Russell06/14/2008

    I have been using this product for the the past few years with my chihuahuas and my one rat terrier and it makes a signifcant difference in their breath and their plaque build up on their teeth. They love the taste of it in their water, actually prefer it over plain water. The chi's are really good chewers but not my rat terrier, and with out the additive in the water you can really tell a difference in his breath, even with brushing his teeth. It's a great product and I tell ll my friends to buy it for their animals absolutely!!! It is much less expensive on this website then any where else also!

    The Best Of The Very Best... by EL GATO from Albuquerque, NM07/30/2012

    The Breathalyser Plus Water Additive (500 mL) is an excellent product. It really does work in keeping the teeth of our 2 cats free of plaque and tartar. I also use PetzLife Oral Care Gel, which also helps to remove Plaque and Tartar. I also brush their teeth. This methodology to me is by far much cheaper than having to pay the Vet. $300.00 per cat to have their teeth cleaned. My wife and I are very impressed with the above products. They really do work.

    Essential! by MissJulie from South Bend, IN02/27/2013

    Wouldn't ever want to be without this fantastic product, really helps keep my elderly dog's teeth from accumulating so much buildup.

    Breathalyser PLUS by BirdmanOKC from Oklahoma City, OK11/14/2012

    Breathalyser PLUS is a wonderful product. I have used it for several years and it does make our pets breath fresher. I highly recommend it!

    Excellent for Dental Care by Sassi from Florida08/03/2014

    Both my cats and my dog drink water with Breathalyser Plus water additive. Their breath is fresh and it seems to be helping the tartar along with the dry food. I have been using it for several years. Sassi

    Product really works! by Carol from Martinez, CA01/24/2012

    Great results in using this product for my 14 year old loving companion Cody! Noticed difference in less than a week. Tried other products before that did not make a difference. Highly recommend this product.

    Breathalyser PLUS Water Additive by Mrbill from Delaware01/09/2013

    We have three toys that had very bad breath. We started putting the product in their water every morning. Within two weeks we could smell a great difference in their breath.

    by bubbles95ca11/30/2011

    Works well. But goes fast because I have three dogs

    Did not help bad breath! by Lynda W. from Va.08/16/2012

    I was disappointed that this did not help my dogs breath. I put it in her water on a regular basis, but it just did not help her. From my experience, and after buying several products that are supposed to help with bad breath, I really think the only thing that is going to help is to have the dog/cats teeth cleaned.

    Some help... by JJ Atlanta03/16/2014

    Our dog's breath was somewhere between "tuna" and "dead animals." Yikes! This product was recommended by the kennel where we board her for vacations. I will say her breath is a bit better, but still pretty "doggy." Maybe there is no total cure.

    Good value. by catpatti from Roswell, GA03/14/2013

    Have mixed with my cats' water since receiving the product. They have no problem with drinking. There is no way to tell the efficacy of the product until a lot more time has gone by and they have vet check-ups.

    It Works! by msbev06/09/2011

    I can not believe how well this stuff works! Our little dog's teeth & mouth were black. He had bad breath. Within a week we began to see a difference & now when he yawns, we see white teeth & no more bad breath! Please continue to carry this product. We were afraid that he might have a really bad tooth but that is not the case. I think we were blessed with this product just in time!

    Helps teeth and breath by smp1939 from Florida01/29/2013

    My dogs would not drink the water with this in it but they are super picky. I am sure it is a good product

    This stuff really works!! by Dbltee from Anderson, In07/24/2011

    I purchased one bottle of the Breathalyser Plus and it worked wonders on my dogs teeth. I have an older dog that has really bad breath and this stuff is amazing. His teeth are cleaner, whiter and he doesn't have a breath issue. I have two other dogs that don't have the same issue, yet, and I want to hopefully prevent that. I ran out of this, so I purchased a cheaper product at a different pet place and thought it might do just as well as this product. Boy, was I ever wrong! So, I'm back and bought a six pack so I won't have to worry about running out for awhile. I won't make that mistake again. Thanks Breathalyser, this stuff really works!
