What is a recommended feature of a toothbrush for effective cleaning?

A toothbrush with soft, nylon, end-rounded bristles is considered a recommended feature for effective cleaning because it provides a gentle yet effective way to remove plaque and debris from the teeth and gums. Soft bristles help prevent damage to the enamel and reduce the risk of gum irritation or recession. The end-rounded design further enhances safety by minimizing the chance of injuring oral tissues during brushing.

This type of bristle is efficient at reaching into the gum line and contours of teeth without causing harm, making it suitable for most individuals, including those with sensitive gums. Additionally, soft bristles allow for thorough cleaning without the excessive force that can lead to oral health issues.
