Biological dentistry looks at the impact oral health has on the whole body. Dental imaging combined with whole body thermography and neural therapy can indicate where there is a connection between physical symptoms and dental issues. Root canals, gum disease and bone infections may harbor bacteria and viruses that can have an impact on our overall health. Choice of filling materials, again, can play a role in health and disease. Furthermore, nutritional status and diet have a strong influence on dental and gum health.
