Tooth Decay is one of the leading causes of tooth loss. Once an infection is present in a tooth, it spreads into the surrounding tissues and causes problems. If identified early, a simple bacterial invasion can be remedied by a dental filling. If the problem is allowed to progress, the infection may spread and wreak havoc in the mouth, eventually leading to the loss of the affected tooth. This book works as a perfect weapon against tooth decay: it is your introduction to this disease, designed to help you fight against it.
