TEEF's mission is to add more years to your pet's life and more life to their years by promoting whole mouth health.



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 Emily Stein, a UC Berkeley and Stanford-trained microbiologist… and a softy 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 close connection between dental health and whole body health.

Dr. Emily Stein, Ph.D., began working on the solution for oral dysbiosis (a key driver of gum disease) in 2008 after she witnessed both her grandmother and 10 year old rescue dog suffer nearly fatal episodes caused by advanced dental disease. Unable to find any safe or effective dental products on the market, she focused on producing consumable oral microbiome-improving products that are 100% safe for human and animal consumption.

Her patented technology in TEEF's Protektin™ formulations leverage a molecular approach called Selective Microbial Metabolism Regulation Technology (SMMRT)®, which is focused on using nutrients to steer bacterial behaviors toward health-promoting vs. disease-causing. It's a natural approach to growing the good bacteria needed for great dental health and fresh breath.

Dr. Stein continues to work to redefine the landscape of oral and systemic health. Her leadership is driving the development of cutting-edge microbiome modulatory products, while unraveling the intricacies of biofilm-related oral and systemic diseases.

She has 18 patents, has delivered over 23 professional lectures on the global stage and has earned numerous awards and accolades, making her a respected authority in the realm of oral microbiome and soft tissue inflammation.

Dr. Stein earned a Ph.D. in Microbiology at UC Berkeley and completed her Post-Doctoral Fellowship at Stanford University School of Medicine, in the Department of Immunology & Rheumatology. The microbiome modulatory technology that she has developed holds promise in addressing an array of diseases that range from dental cavities and periodontal disease to cancer and diabetes.

We’re here to fix more than bad breath. 

We’re here to create WHOLE-BODY, FEEL-IT-IN-YOUR-BONES, BELOW-THE-GUM-LINE oral health.

Combining the fundamentals of microbiology and molecular nutrition, our technology promotes dental health safely.




In every mouth, there is a never-ending battle between good bacteria and bad bacteria, and your pet’s body needs the good bacteria in order to thrive. Our science works deep below the gumline to preserve, protect and grow the good guys to create a beneficial oral microbiome. By embracing the true driver of overall health, we fight against bad breath, tooth loss and disease.



Our passion to do right by pets and their people never waivers. We are entrepeneuers, microbiologists, and pet lovers using our unique knowledge of molecular nutrition to create groundbreaking technology and deliver the best possible products on the market.



We believe our pets deserve more than antiquated, toxic approaches when it comes to lasting health and longevity. Infact, all animals deserve the best life possible through products built responsibly. Our science goes beyond typical ingredients to create formulations made with natural, unadulterated ingredients that are safe for the bodies of pets and humans alike.
