Dr. John Gontarz, PhD

Dr. John Gontarz, who holds a PhD in Organic Chemistry and has 30 years of experience developing ingredients for cosmetic and personal care products, turned his expertise towards oral care after retiring. Motivated by his personal battle with tartar, plaque buildup, and periodontal disease, Dr. Gontarz developed a toothpaste to remove tartar and reverse periodontal disease, impressing his dentist with his results. This led to the creation of the patented TartarEnd® toothpaste. Now on a six-month cleaning schedule with healthy teeth and gums, Dr. Gontarz established TartarEnd LLC in 2016, securing US and foreign patents for his innovative formulation. TartarEnd® toothpaste, available online in many countries, dissolves plaque and tartar, halting periodontal disease progression and preventing tooth loss and cavities. His blogs further explain the chemical processes behind dental issues and how to address them at home.
