The Oral-B Pro 3D White replacement brush heads, available in a pack of 10 units, are designed for use with Oral-B Pro, Vitality, Genius, and Smart Series electric toothbrushes. These brush heads feature a polishing cup design that effectively removes surface stains and contributes to teeth whitening. The cross-arranged bristles ensure thorough cleaning by reaching difficult areas such as between teeth to remove plaque. Each brush head has a color-changing indicator with green bristles that turn yellow, signaling when a replacement is needed for optimal oral hygiene. This pack provides an approximate 2.5-year supply based on the standard use of one brush head every three months. Made from durable materials, the brush heads offer consistent performance and are compatible with a wide range of Oral-B electric toothbrush models for reliable daily care.
