Toothbrush is one of the most common and important cleaning tools in our daily lives. Every morning and evening, we pick up our toothbrushes, squeeze toothpaste on them, and brush them in our mouths for two minutes. But have you ever thought that behind this small toothbrush, there is actually a lot of knowledge hidden?

The history of toothbrushes can be traced back thousands of years. In ancient times, people used tree branches, animal hair, and even shells to clean their teeth. The modern toothbrush originated in China in the 15th century, later introduced to Europe, and gradually evolved into the style of nylon bristles and plastic handles we use today.

At present, the commonly used toothbrushes on the market are mainly divided into two categories: manual toothbrushes and electric toothbrushes. Manual toothbrushes are cheap and easy to use; Electric toothbrushes can effectively remove dental plaque through high-frequency vibration, making them suitable for people with sensitive teeth or those who pursue efficient cleaning. The softness and hardness of bristles can also affect the brushing effect. It is generally recommended to choose medium soft bristles to reduce irritation to the gums.

Proper use of toothbrushes is also crucial. The brushing time should not be less than 2 minutes each time, using the correct brushing method (such as the Babbitt brushing method), and regularly changing the toothbrush (it is recommended to change it every 3 months). In addition, the size of the brush head should be adapted to the oral structure to avoid being too large and unable to brush the posterior teeth.

Although toothbrushes may look ordinary, they directly affect our oral health. Choosing a suitable toothbrush and mastering scientific brushing methods is the first step in protecting the health of teeth and gums. Don't underestimate this toothbrush, it's a good companion you can't live without every day!
