Final answer:
A very soft bristled brush is typically used for delicate tasks like painting, particularly with ink in Eastern art traditions. Soft bristles minimize damage to delicate surfaces. In the realm of oral care, soft bristled toothbrushes are used for cleaning sensitive teeth and gums.
Step-by-step explanation:
The brush with very soft bristles can serve multiple purposes depending on its design and the context in which it is used. In arts, soft pointed brushes are frequently utilized in painting for making drawings with ink, especially in Eastern traditions. These brushes provide artists with the ability to vary the width of the line and add subtle details to their work. In contrast, when it comes to oral hygiene, brushes are designed with an array of bristle textures, but usually, toothbrushes with very soft bristles would be aimed at cleaning sensitive teeth and gums or for use by young children. The softness helps prevent damage to delicate tooth enamel and gum tissue.
Oral hygiene is also deeply linked to social norms and health practices, with toothbrushes being a staple item in personal care routines. This aspect of toothbrushing is a cultural constant, though the materials and designs of toothbrushes have evolved significantly since their invention in 15th-century China.
