The Philips Sonicare Prestige 9900 Blue and Cream Duo Pack includes two electric toothbrushes that automatically adjust the brushing mode and intensity based on individual brushing habits. Each toothbrush measures brushing pressure, movement patterns, duration, and coverage areas 100 times per second to ensure optimal cleaning performance for your specific dental needs. The SenseIQ technology allows for real-time adjustments to provide the most suitable brushing intensity for your teeth and gums. For enhanced brushing feedback, connect the toothbrushes to the smartphone app, where you can monitor progress through detailed oral mapping and receive personalized brushing improvement suggestions. The package includes two charging stations, allowing simultaneous use by two people. Each toothbrush comes with an all-in-one brush head featuring triangular bristle tips and extended filaments designed to effectively clean hard-to-reach areas between teeth and along the gum line. The handle provides replacement notifications when brush heads need to be changed. With regular use across various brushing modes, the battery may require more frequent charging. Each toothbrush measures approximately 22 cm in length and weighs about 150 g, providing comfortable handling during use. The blue and cream color combination offers aesthetic appeal while maintaining professional dental care standards. This duo pack is suitable for household use, ensuring consistent oral hygiene care for multiple users with individual brushing preferences and requirements.
