TEEF! Technology

Science Matters

We use only human-grade ingredients with years of proven efficacy and safety for people AND pets. These nutrients steer the behavior of oral bacteria toward more health-promoting behaviors to help balance the oral microbiome for a healthier mouth.

Our TEEF! powder formulation for pets is called Protektin, a patented combination of 4 naturally safe, bioactive ingredients:


Outsmarts & neutralizes bad bacteria


Prevents plaque buildup and bacteria odor


Empowers beneficial bacteria


Strengthens and whitens teeth

Our patented science selectively favors health-promoting bacteria to flourish in your pet’s mouth, while disrupting dangerous bacteria, so your pet can benefit.

Our Mission

TEEF! is pioneering the development of innovative products to create a world free of dental disease and all the emotional and financial costs associated with it.

It all started with a senior rescue dog

Saved from a shelter at 10 years old, Tinzley had multiple health conditions that all traced back to neglected dental care. Luckily, she was adopted by Dr. Emily Stein, a UC Berkeley and Stanford-trained scientist with an extensive background in microbiology and immunology… and a soft spot for older dogs.

She knew immediately that oral bacteria were the source of Tinzley’s eye and bladder infections, skin irritations and lack of energy. After 4 months of antibiotics, 21 tooth extractions and thousands of dollars in vet bills, Tinzley was finally healthy again. All these issues stemmed from the connection between the mouth and body.


Frequently Asked Questions

What are the ingredients in TEEF?

Simply put, our formula consists of 4, pure and safe ingredients: a soluble fiber, a vegan protein, sodium bicarbonate (baking soda) and a vitamin. All are in fine powder form and dissolve rapidly in water.

Not good enough? We truly value ingredient transparency and understand if you have a deeper level of curiosity. However, in this competitive online landscape we would prefer you inquire with us directly for more detail. Please contact us at

Why does TEEF! turn the water slightly yellow?

The vitamin in our Protektin formula turns yellow when it comes in contact with water. But don’t worry, there’s no harm in the color change and the small amount won’t affect the flavor of the water. Your pup shouldn’t notice anything.

NOTE: Keep our powder clear of clothes and other absorbent materials to avoid staining.

Is it safe for cats?

Absolutely! However, because cats have very different diets than dogs, our formula for dogs won’t be very effective on them. Our R&D team is working on a feline-specific formula and expect to release it by the end of 2019.

Interested in helping us with our R&D? We will send you a swab kit to collect a sample from your furry friend. It’s minimally intrusive, you’ll just need to swab their tongue and gums to collect their oral biofilm and send it into our lab for bio-hacking (pre-paid postage). Please send us an email with your address –

Is this tiny amount of powder enough?

You bet! That’s the science behind TEEF! Our ingredients dissolve rapidly and disperse evenly in the water dish, no matter the amount. The key to success is frequent dosing throughout the day. That way our ingredients wash over the bacteria in the mouth often to balance the oral environment and make it less acidic and destructive to dental health.

We pride ourselves on using only pure ingredients – no fillers, preservatives, artificial colors or flavors, or other weird ingredients that cause “dog-arrhea”.

I have a multiple dog home, how should I dose?

No problem! Our dosing is simple. Just add one leveled-off scoop of TEEF! to each water bowl and repeat with each refill.

What are the dosing instructions?

Simply add one leveled-off scoop (scoop provided) in your dog’s fresh water dish. Repeat with each refill.

Lost the spoon? We will send you another or just add a pinch to their water dish!

Is it safe for puppies?

Yes, TEEF! is safe for puppies. However, due to their somewhat sensitive puppy GI tracts, the tiny amount of sodium bicarbonate (baking soda) may cause minor regurgitation in the first several drinks as they get used to it. It’s not harmful, it’s just their bellies reacting to the faint bubbles.

My dog doesn't drink much water, can I add TEEF! to food?

You can certainly try that, however, we can’t guarantee that it will be effective. Dogs normally eat 1-2 times per day (and throw it down pretty fast) and the key to success with TEEF! is frequent dosing throughout the day. That way our ingredients coat the mouth often to consistently balance the oral environment and make it less acidic and destructive to dental health.

Suggestion – Does your dog like ice cubes? You can try making some TEEF! ice cubes and see if your pup enjoys it that way. Make sure they keep the ice cube on a hard surface though, the vitamin in our formula can potentially cause staining.

What should I do if my pup isn't drinking their TEEF! water?

Although it’s rare that pups drink less water when TEEF! is added, it’s very important to keep Fido hydrated. We recommend scaling back on the amount you’re adding to water and observing if there’s still any avoidance.

If your pup still won’t drink their water, please contact us, We have a 60 day money back guarantee in the case that your pup refuses to drink their water with our product in it.

I'm noticing that my pup has looser stools when using TEEF!

Some pups with more sensitive GI tracts will have softer poos as a result of the soluble fiber in our product. This isn’t a harmful reaction, it’s just that, well… fiber makes you poop. You can try scaling back on the dose to keep this from happening.

What do you mean by human-grade?

Our water additive consists of ingredients that have been tested for safety on humans and animals for over 40 years. Our initial formulations were intended for human consumption. We even have some humans that are adding TEEF! to their own drinking water.

How does it work?

Our patented Protektin formula packs a quadruple-action punch to the bacteria in the mouth to balance the oral microbiome. This balance promotes strong teeth, healthy gums and fresh breath. It’s unlike anything else available in the market!

One ingredient works to block the bacteria from consuming dietary sugar so they can’t convert it into acid and plaque. The vitamin  enables health-promoting bacteria to eat protein instead of sugar, resulting in healthier (meaning less acidic and anti-inflammatory) by-products. The third ingredient neutralizes saliva acidity, which results in a less destructive environment in the mouth. And, finally, the fourth ingredient is a disruptor that helps remove the existing dental biofilm (plaque and tartar) from teeth for stronger, whiter teeth.

How will I know if it's working?

You’ll first notice an improvement in breath. It won’t smell like roses, it will smell like nothing at all!

Keep an eye on the whiteness of your pup’s teeth. We tell people to keep an eye on the back molars since this is where the most tartar builds up. You might notice that some of the tartar is actually coming off.

Take a look at the color of the gums. Our product is unique in that it even targets the bacteria below the gum line which can result in pinker, healthier gums.

Still not a believer? Contact us and we’ll send you a swab kit so you can send us a sample of your dog’s bacteria readings before you start TEEF! and after 14 days of use. Our past studies have shown a significant reduction in enteric (poop-associated) bacteria like E. coli, Salmonella, and other nasty germs. Contact

Why is TEEF! so darn cool?

Our co-founder and inventor is a super-geeky-smarty that earned her PhD in microbiology at University of California at Berkeley and then completed her fellowship in Immunology and Rheumatology at Stanford University. Her exceptional understanding of microbes and their impact on human and animal health helped her discover how to steer their behaviors using simple nutrients.

“Bacteria are the most primal, essential organisms on Earth. Their collective power often goes unnoticed and they contribute significantly to health and wellness or the alternative. Our goal is to build products that empower these primal organisms to work for our benefit.” – Emily Stein, PhD, Co-founder & CEO

Dog dental chews – Research required

Dog dental chews – Research required

Common knowledge says that dogs need to chew on something in order to remove plaque and tartar from their teeth.

It makes sense, right?

Much of the same logic is used in human dental care. Brush, scrape, remove. However, an article published by VetStreet named six common dental chew products owners should avoid due to their threat of potential tooth fractures, gastrointestinal obstruction and gastroenteritis (among other issues).

Some of the top “no-no” chews are:

  • Raw hides
  • Dried pig ears
  • Antlers
  • Cooked bones
  • Rocks
  • Cow hooves

Many of these products contain chemicals, artificial colors, preservatives, detergents, and other additives that can be unhealthy and potentially dangerous.

And, let’s admit it… they’re just plain messy and gross.

Thus, the “dental chew” was born as an alternative dental care approach for dogs. Dental chews are products that can be effective at removing some plaque and tartar, however, veterinarians across the country stress the fact that effective is relative when it comes to many dental chews and other tartar control products.  Dr. John Huff, Board Certified Veterinary Dentist states, “‘Effective’ is relative. If brushing is a hundred [percent], treats and chews are probably a one.”  He adds, “The positives on the VOHC-approved dental products are [that] they are better than nothing.”(1)

There’s also the question of safety.

Dental chews are a readily available and commonly used class of products, although many owners and veterinarians question their safety, both the sources and ingredients.

Most dogs consume dental chews without issue but some have suffered health problems (and even death) due to these teeth-cleaning treats because of potential toxins and contaminants in the products. So it’s important to use caution when buying “dental care” products for your pup.

Dr. Huff, also states, “Though I have found all the Veterinary Oral Health Council-approved products to be safe and effective, the VOHC does not test for safety.”(1) 

To help limit some of these types of risks:

  • Research the ingredients in the product
  • How products are made
  • Where products are manufactured
  • Also, be sure to select the proper size chew for your pup and try to ensure they chew the treat thoroughly before they swallow. In other words, don’t be this guy…

There are a number of safe options for dog dental care like wipes, sprays, gels, probiotics and other molecular approaches. The associated chart gives a high-level overview of common dental care approaches (shameless product plug). As you’ll see, there are other safe ways of taking care of your pup’s mouth, just make sure you do your research to ensure the ingredients in those products are nontoxic.

We’re excited to announce that we will be launching our Indiegogo campaign in November to raise funding for manufacturing. Want to stay up to date on TEEF!? Join our mailing list.
