Holistic Dentistry

Our Philosophy

At Renewal Dental Arts, we proudly practice biological dentistry in San Antonio—combining advanced technology with a holistic approach that supports your total health and well-being. Our philosophy goes beyond treating teeth; we consider how oral health impacts the entire body and tailor our care to support healing from the inside out.

As a trusted biological dentist in San Antonio, we use only biocompatible materials and minimally invasive techniques. We offer ceramic dental implants as a metal-free, highly aesthetic, and body-friendly alternative to traditional titanium implants—ideal for patients with sensitivities or those seeking a more natural solution.

We also provide safe amalgam removal following strict protocols to protect you from mercury exposure, using advanced filtration and isolation systems. Our use of ozone therapy further enhances healing, disinfects naturally, and reduces inflammation—making it a powerful tool for treating decay, gum disease, and even tooth sensitivity without harsh chemicals. As part of our commitment to holistic care, we are also a fluoride-free dental practice, using safe and effective alternatives like nano-hydroxyapatite to support remineralization and oral health naturally.

From mercury-free fillings to ceramic implants and ozone-enhanced treatments, Renewal Dental Arts is your destination for modern, compassionate, and health-centered dental care. Experience the difference of a biological dentist in San Antonio—where your health, comfort, and peace of mind always come first.
