The Oral-B Toothbrush Ultra Thin Extra Soft is a manual toothbrush specifically engineered for individuals seeking a deep clean that is exceptionally gentle on sensitive gums and teeth.

This model is a part of the "UltraThin" or "UltraThin Pro Gum Care" line, and its key features focus on bristle technology:

Bristle Firmness: Extra Soft (often labeled "Sensitive")

Bristle Design (The "Ultra Thin" Advantage):

Ultra-Thin Bristles: The tips of the bristles are incredibly narrow (often less than 0.01mm) and are described as being 20 times thinner at the tip compared to regular bristles.

Deep Reach: These ultra-thin tips are designed to be flexible and reach up to 2× deeper between teeth and along the gumline than standard flat-trim bristles.

Gentleness: Despite the deep reach, the super-thin tips remain gentle on the enamel and are specifically designed to be soft on the gums, making them ideal for sensitive mouths.

Gum Health: The focus on gentleness and the ability to clean along the gumline is intended to help improve gum health, with some product descriptions suggesting visible improvement in gum state within a couple of weeks.

Handle: It typically features an ergonomic handle for comfortable grip and control.
