The problem, in a nutshell.

The mouth contains billions of beneficial and harmful bacteria. Overgrowth of harmful bacteria causes an imbalance of the oral microbiome and results in inflammation, cavities, gum disease, and bad breath. Our technology displays the ability to shift the oral environment from disease-causing to health-promoting in as soon as five days.

The prebiotic technology in Daily Dental Care pHossident lozenges was invented by Emily Stein, PhD, after she witnessed her grandmother suffer from severe health issues caused by dental disease. Her background in microbiology and immunology gave her a unique understanding of the nature of bacteria and how they impact human and animal health.

Total health begins in the mouth.


Our founder’s motivation for establishing Primal Health’s technology in Daily Dental Care stems from her love for her grandmother, who experienced a health crisis due to neglected dental hygiene while in assisted living. After several tooth extractions, she suffered a major stroke which significantly impaired her mobility and quality of life. Witnessing the downward spiral of her grandmother’s health linked to something as simple and preventable as dental disease motivated her to find a solution.

In 2010, she began screening Generally Recognized as Safe (GRAS) ingredients by the FDA in search of a combination that was effective and safe to consume. Studies have shown that pHossident™, the first patented combination of ingredients, addresses acid production, oral biofilm (plaque) production, and growth of disease-causing bacteria associated with cavities, gum disease, and bad breath. Also, studies showed the efficacy on growing beneficial bacteria, essential for dental health. pHossident was then added it to a convenient lozenge for easy, convenient administration…especially for her grandmother.

However, during her research and development, she gained a full understanding of just how severe the oral care crisis is here in the U.S. and around the world. Primal Health is a biotechnology company with an overarching goal of improving public health by developing groundbreaking supplemental dental hygiene products that are proactive in managing dental health.
