Dr. Lina Garcia, a dentist and surgeon with over 30 years of experience, returns to The Deen Show to discuss one of the most important yet overlooked health topics: the direct connection between oral health and overall body health. The same blood that circulates around your teeth and gums flows through your heart, joints, and every organ. An infection in your mouth does not stay in your mouth — it enters your bloodstream and can cause arthritis, heart problems, autoimmune disease, and far worse. This holistic understanding of dental health, combined with the Sunnah practice of using the miswak, offers Muslims a powerful framework for taking control of their wellbeing as Allah intended.
The Danger of Root Canals and Dead Teeth
“Every tooth in your mouth is like an organ — it has blood supply, lymphatics, everything. When a tooth has a root canal, it is no longer alive. It is a dead body in your body, harboring pathogenic bacteria that release toxicity into your bloodstream and cause disease in remote areas — your knees, your heart, anywhere.”
Dr. Garcia has performed thousands of biopsies on extracted root canal teeth, and virtually every one was heavily infected with dangerous microorganisms. The pioneering work of Dr. Weston Price — whose own son died from an infected root canal tooth — demonstrated over a century ago that dead teeth in the body cause systemic disease. Yet this research is still not taught in conventional dental schools. The good news is that in about 80% of cases, Dr. Garcia has been able to reverse the conditions leading to root canals by addressing nutrition, stress, sleep, and inflammation — saving the tooth’s nerve without the need for the procedure at all.
- Root canals create dead teeth that harbor pathogenic bacteria, releasing toxins into the bloodstream that can affect the heart, joints, and immune system
- Metal dental implants (titanium) cause galvanic activity in the body — zirconia ceramic implants are a safer, biocompatible alternative
- The miswak (Sunnah tooth stick) killed 20% of bacteria in studies, compared to only 3.6% for ordinary mints, as published in the Journal of Agricultural and Food Chemistry
- Changing nutrition — eliminating sugars, refined carbohydrates, and processed flour — can reverse dental inflammation and buy time before making irreversible decisions
- Ozone therapy, homeopathic antibiotics, and digestive enzymes are effective alternatives to pharmaceutical antibiotics for oral infections
- In 30 years of practice, Dr. Garcia has not prescribed conventional antibiotics or pain medications, even for major surgeries
The Miswak, Nutrition, and Taking Control of Your Health
“We can heal cavities, gum disease, and autoimmune problems. We have to totally change our minds. The system supports disease because it makes money. Nutrition is basic for any area of medicine — if we change what we eat, sleep better, and reduce stress, we give the body the chance to heal as it was designed to.”
The lesson for every Muslim is clear: your body is an amanah from Allah, and maintaining it requires more than just reacting to disease — it requires proactive, holistic care. The miswak, which the Prophet Muhammad (peace be upon him) recommended, is backed by modern science as a powerful antibacterial tool. Proper nutrition, avoiding processed foods and sugars, and choosing practitioners who treat the whole person rather than just symptoms are all within your control. Do not give all your power to a system that profits from keeping you sick. Educate yourself, seek holistic guidance, and take responsibility for the health Allah has entrusted to you.
