Brilliant Brush Heads, after years of research our oral hygiene engineers have developed the ultimate brush head for all mouth types. Slim head for manoeuvrability, alternate bristles heights for a deeper clean, a silicone textured back to massage the inner surfaces of your gums and polishing element designed to help whiten your teeth using a gentle polishing action. DuPont bristles are soft and individually rounded for a clean that's gentle on gums and tooth enamel, yet tough on plaque. Recommended by dentists. Silicone polishing element works to help remove surface stains. Sonic pulse technology utilises fluid dynamics to clean deep between teeth. Removes more plaque vs a manual. Our brush heads are easily interchangeable with a simple push-fit design.
