SMMRT®, developed in 2008 by founder Emily Stein, Ph.D., is the patented, foundational science behind TEEF and the secret to its success. This revolutionary approach to improving the oral microbiome combats the bacterial carbohydrate-driven processes that cause dental disease. Focusing on using natural nutrients to influence bacteria toward health-promoting behaviors, rather than killing all of them, results in far better health outcomes. 


“After just 3 days of using TEEF in just one of the multiple bowls of water throughout the house, we immediately noticed a significant difference in his breath! We’re big fans and I’ve even ordered two bottles of the human version!”

“This is a very simple way of being very proactive in helping minimize the bacteria accumulation that can live on and below the gumline, improve the quality of life for the animal, as well as the integrity of that periodontal ligament in teeth.”

– Dr. Adam Christman, DVM360 Chief Veterinary Officer

We’ve used the product for 4 months now. With 3 dogs, one having horrible breath I can tell you it is worth the cost. I’ve used other products and nothing worked until TEEF. It takes about a month of use before you see a marked difference

“My Retriever mix had 7 teeth pulled 2 years ago due to tooth decay and continues to have awful butt breath. Started TEEF! with our dogs just last week and we have noticed a significant change. Definitely a winner and waiting for my next batch to keep seeing such great progress with our four-legged family members. Neither of them let me brush their teeth so this product is awesome and easy. Highly recommend!”

“After only 7 days of using TEEF!, I was able to flick off Maddie’s tartar with just my fingernail! And when I woke up in the morning, the tartar on the other molar had come completely off, too. I couldn’t believe it! I can’t wait to get more product to keep her teeth clean without having to put her under anesthesia.”

– Katie C.

“I tried TEEF! for 2 weeks and after day 6 there was a noticeable improvement in my dog’s breath. By day 12 her teeth were also whiter and her molars looked like some of the tartar had sloughed off. The small amount of powder in her water bowl is easy to remember and she had no problem drinking it. We will be making this part of our morning routine!”

– Sue M.

“I have an 11 year old German Shepherd mix who had a TON of tartar build up and unbearable breath. After only 14 days of using TEEF! her teeth became much whiter, there’s less tartar and her unbearable breath is totally gone. This stuff rocks! I can’t wait for this product to hit the market. Thanks team TEEF!”

– Jody J.

“I’m a huge fan of Teef!  I’ve been using this for our dogs & BONUS, it changed Brady’s breath from NASTY to neutral!  I’m thrilled to know how much additional “good stuff” is happening that I can’t see.  Plus, Brady has a SUPER sensitive tummy and this didn’t bother him at all.  Thanks Dr. Emily Stein!!!  You are a rockstar scientist!”
