INTERSPACE BRUSH HEADS - These brush heads are ideal tools for cleaning interdental spaces, braces, bridges, and implants. THOROUGH CLEANING - Powerful tip bristles clean between teeth and under the gum line one by one for cleaner teeth and less gingivitis. REACHES HARD TO REACH AREAS - The smaller brush head and slim bristles make it easy to reach hard-to-reach areas, making it especially suitable for people who want a deep clean and for those with braces. GREAT VALUE FOR MONEY - The brush head is made of high-quality bristles with rounded ends, which provides comparable performance to the original brush head, but saves you money on your daily expenses. FULLY COMPATIBLE - These brush head attachments are compatible with most Oral-B electric toothbrushes. (Not compatible with Pulsonic, iO series.) Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
