From hog hair toothbrushes and cavities packed in linen to rechargeable electric toothbrushes and laser dentistry, dental care has come a long way. Over thousands of years, as the field of dentistry has evolved, research has provided answers to the gross but fascinating science that’s behind bad breath and cavities. This comprehensive guide offers readers the chance to learn about the thousands, sometimes millions, of microorganisms that live in people’s mouths, the history of oral hygiene, and the many myths, facts, causes, and treatments related to bad breath and cavities.
