Science and technology have changed our lives. Because of advances in medicine and our understanding of the human body, we are living longer and more healthy lives. But many are concerned about our seemingly uncontrolled use of synthetic drugs and substances. Could the things we use that help us live more comfortably actually be hurting us in the long run?
Our mouths are literally our gateway to the world. Everything we eat, drink, and breathe passes through our mouths and becomes part of our bodies. Recently, many people have started to question the wisdom of using potentially harmful substances, such as certain metal amalgams used to fill cavities, in their dental care. There is some evidence that these substances may cause harm in the long run. This can be especially true for children, whose growing bodies are sensitive in ways the adult body is not.
