Best Water Additive for Dogs Teeth 2022 – Buyer’s Guide

Dogs are often described as pampered and it is true that people spend extravagantly on what are essentially peripheral items and treatments for their pets. That said, it can be easy to neglect areas where dogs really could do with some pampering; health being prominent on this list. One can see why because not many dogs relish veterinary visits or even some owner-administered treatments.

If you have ever tried to brush a dog’s teeth, you will be aware that it is not a routine which sets the tail wagging. It is, however, an important part of their well-being.

Neglect those incisors and molars and canines and you will discover that a dog’s dental upkeep is a requirement as urgent as our own. And veterinary bills can be just as exorbitant as dentists.

Oratene Brushless Oral Care is a dental water additive with impressive scientific credentials. In a field where homogeneity abounds, this product’s manufacturers take a more holistic approach by converting the results of diligent research into a winning formula. The formula emanated from the human production line for treatment of Xerostomia (or dry mouth) and has been applied successfully to arrive at this dental water additive.

Oratene contains the patented LP3 Enzyme System which releases enzymes into the water; enzymes which help dogs to break down food and absorb its nutrients, thereby helping to keep their gums healthy and clean.

Devoid of flavor or odor, Oratene adds vitality and protection to the water bowl and is of particular appeal to dogs with an aversion to having their teeth brushed. It can be accompanied by a gel which will enhance the protection.

Complementary Dental Fresh products comprise a comprehensive course of treatment to address all matters dental for dogs (and cats). The self-regulating formula used tackles different aspects of dental concern and can adjust to the requirements of different animals.

5. Emmy’s Pet Dental Care Water Additive: Best Fresh Smelling Additive

Not just fresh breath either, we received testaments to its ability to fight tartar. Emmy’s acknowledge the struggle it can be to make a dog amenable to toothbrushes and pack their water additive with a formula to alleviate tartar and plaque.

Arm & Hammer also delivers when it comes to freshening dogs’ breath and its usage of natural ingredients helps to eliminate unwanted side effects. Users have reported pretty immediate results when immersing a small amount of the additive to their dogs’ drinking water.

Guide to Dental Water Additive for Dogs

It has been estimated that upwards of 80% of dogs over three years old experience periodontal disease i.e. inflammation or infection leading to a weakening or loss of support structure for teeth through a build-up of plaque and tartar. Gums become weaker, bone problems develop, and the dog’s general demeanor may be affected. In turn, the presence of bacteria can inveigle its way into the dog’s bloodstream with consequent problems in due course. Aside from the health issues, there is also the problem of halitosis (or bad breath); something pretty much unavoidable for dogs.

Based on that 80+% statistic and the inevitability of bad breath, it is a given that dogs will encounter dental issues, so this article is not focused on how to recognize them but how to prevent their onset. We also hope to provide advice which will ultimately alleviate any discomfort and/or pain caused by dental concerns…and to improve the animal’s breath. Veterinary advice is to brush your dog’s teeth daily but, as mentioned above, that isn’t always easy. There is, however, an alternative (or an aid) in the form of dental water additives.

What are Dental Water Additives?

Dental water additives for dogs are a relative newcomer to the field of canine dental health. They are often compared to mouthwash for humans and contribute to the arsenal of weapons at the disposal of dogs to fight against dental problems. The ingredients in water additives include organics, mineral salts, and chemical antiseptics. They work to dissect plaque and act as anti-bacterial agents in purifying the dog’s drinking water and strengthening their immune system.

Water additives come in the form of powder or pills or in liquid form which are immersed in the water bowl. Dogs should be amenable to taking them as many are odorless and tasteless for ease of consumption.

Advantages of water additives

What to look out for in the ingredients

Dogs have a reputation for rarely turning their nose up at whatever is presented to them in a bowl but that generalization masks the eating sensitivities inherent to many dogs. A scan through the ingredients in some water additives may cause mild alarm but rest assured that the ever-vigilant food authorities maintain close scrutiny on their composition.

In the US, pet food products must adhere to federal and state requirements with stringent regulations applied to the ingredients by the Food & Drug Administration (FDA). Elsewhere, in Europe the EU (Animal & Plant Health Agency) and UK (Food Standards Agency) apply similar controls which are continuously monitored.

Still, it behooves us to provide a quick run-through some of the ingredients included in dental water additives which dog owners may need to be aware of lest they impinge upon any known issues with their four-legged friend. Most of the brief analysis below is to provide reassurance before purchase.

Chlorhexidine is classified as a disinfectant and antiseptic which is effective against bacteria and viruses but can have adverse effects when used near the ears, eyes, and mouth of animals (increase in tartar and mouth/gum inflammation). It is now rare to find Chlorhexidine Gluconate in dental water additives any which do are best avoided.

Xylotil is a sweetener but one which has been known to cause stomach problems to dogs which have proved fatal. It is still included in some canine dental products but should also be avoided.

Chlorophyllin is the green pigment in grass which is sometimes found in water additives. It is perfectly OK for dogs and acts as an effective agent to freshen their breath.

Glycerin acts as a sweetener in lots of foodstuffs and while it doesn’t provide any real nutritional benefit, it is non-toxic for dogs.

Sodium Benzoate is a preservative which if taken in excess can be cancerous. However, the amount included in most dental products is very low and it should not be a cause for alarm.

Parabens are preservatives which have been reported to cause skin allergies for some dogs. Tests have proven inconclusive in finding a definite link and the FDA’s take is that the small amounts in dog products should not cause any harm.

Potassium Sorbate is an anti-bacteria agent and is perfectly safe for dogs in low amounts.
Sorbitol is a flavoring agent which is often confused with Xylotil (see above). Sorbitol has laxative properties but only when taken in large amounts. Small quantities are the norm when included in dental water additives and should not be a problem.

Conclusion

After some of the negativity in the ingredients section, it should be noted that the chances of dental water additives actually leading to problems are minimal and that, as advised elsewhere in this feature, they do provide significant benefits to animal and owner. For most products, some careful selection would be rewarded in choosing one which best suits your dog but, to be honest, dental water additives are pretty homogenous.

We hope the task of selecting a dental water additive for your dog has been made somewhat easier by our assessments and testimonials, all based on independent evaluations.
