tandbørste

A tandbørste, commonly known as a toothbrush, is an oral hygiene tool used to clean teeth and gums. It consists of a head with bristles mounted on a handle. The bristles are typically made of nylon and come in various lengths, stiffness levels, and arrangements designed to effectively remove plaque and food particles from the surfaces of the teeth and along the gumline.

Toothbrushes are essential for maintaining good oral health and preventing dental problems such as cavities and gum disease. They are used in conjunction with toothpaste, which contains abrasives and fluoride to aid in cleaning and strengthening tooth enamel. The act of brushing involves moving the toothbrush over all surfaces of the teeth in a systematic manner.

There are two main types of toothbrushes: manual and electric. Manual toothbrushes rely on the user's own brushing technique. Electric toothbrushes, on the other hand, use a powered head that oscillates, rotates, or vibrates to do the cleaning, often requiring less user effort and potentially offering a more thorough clean for some individuals. Both types require proper technique and regular replacement to remain effective. Dentists typically recommend replacing a toothbrush every three to four months, or sooner if the bristles become frayed.
