When Was the First Toothbrush Invented? A Historical Overview

Introduction

The toothbrush is an integral part of oral hygiene and is used by people around the world. But when was the first toothbrush invented? The answer is not as straightforward as it may seem. To understand the history of the toothbrush, we must look at early oral hygiene practices, the first known toothbrush and its inventor, and how the toothbrush has evolved over time.

Historical Overview of the Invention of the Toothbrush

Before the invention of the toothbrush, early civilizations practiced various methods of oral hygiene. Ancient Egyptians and Greeks chewed on twigs or sticks to clean their teeth and freshen their breath. These sticks were soaked in herbs, salt, or other substances to improve their cleaning power.¹ The Chinese are credited with inventing the first known toothbrush, which was made with boar bristles, during the Tang Dynasty (618–907 AD).² This type of toothbrush was improved upon by the Persians, who added a handle to the design for easier use. Over the next few centuries, the toothbrush spread to Europe, where it gained widespread popularity.

The First Known Toothbrush and Its Inventor

The first documented instance of a toothbrush with bristles comes from the 15th century, when William Addis of England created one out of bone and bristles from pigs’ necks. According to legend, Addis was arrested for starting a riot in 1770 and spent the next seven years in prison. During his incarceration, he crafted the first mass-produced toothbrush.³ After his release, Addis established a business that manufactured and sold his toothbrushes, which became popular throughout Europe.

How the Toothbrush Evolved Over Time

The basic design of the toothbrush has remained largely unchanged since it was first invented. However, there have been some significant improvements in materials and technology over the years. Early toothbrushes were made with animal hairs, such as horsehair, hog hair, and badger hair. In the late 19th century, synthetic bristles began to be used, and by the mid-20th century, nylon had become the material of choice for most toothbrush manufacturers.⁴

In addition to changes in materials, there have also been improvements in toothbrush technology. Electric toothbrushes were first introduced in 1939 and have become increasingly popular in recent years. These brushes feature rotating heads and are designed to make brushing easier and more effective.⁵ Sonic toothbrushes, which use high-frequency vibrations to remove plaque, have also become popular in recent years.

The Impact of the Toothbrush on Oral Hygiene

The invention of the toothbrush has had a huge impact on oral hygiene and dentistry. Using a toothbrush helps to remove plaque and bacteria from the teeth, reducing the risk of cavities and gum disease. It can also help to prevent bad breath and protect against tooth decay.⁶ Regular tooth brushing is an essential part of maintaining good oral health.

The toothbrush has also played a major role in modern dentistry. Dentists recommend using a toothbrush with soft bristles and a small head, as well as brushing gently and in short strokes. They also advise brushing twice a day and replacing your toothbrush every three months. Following these guidelines helps to ensure optimal oral hygiene and prevents plaque buildup.⁷

Conclusion

The first known toothbrush was invented in 15th century China and was later improved upon by William Addis of England. Since then, the toothbrush has undergone numerous changes in materials and technology. Today, the toothbrush is an essential part of oral hygiene and is recommended by dentists worldwide. Knowing when the first toothbrush was invented is important for understanding the evolution of dental care and the importance of proper oral hygiene.
