Description

Experience a new standard of oral care with the Philips Sonicare DiamondClean 9900 Prestige. This advanced sonic toothbrush is designed to provide a deep, efficient clean that removes up to 20x more plaque than a manual toothbrush. Within just two weeks, you can achieve up to 15x healthier gums, and the technology helps remove up to 100% more stains in less than two days for a brighter smile. Equipped with SenseIQ technology, this toothbrush senses your brushing style and adapts in real time. If you apply too much pressure, the built-in light ring flashes to remind you to adjust, protecting your teeth and gums from damage. With five distinct brushing modes including Clean, White+, and Gum Health, you can customize your routine to meet your specific needs. The A3 Premium All-in-One brush heads provide comprehensive coverage, ensuring every area of your mouth receives professional-level attention. Complete with a charging travel case, this black electric toothbrush is the ultimate tool for maintaining a healthy, radiant smile anywhere you go.

Key Features

SenseIQ technology automatically adapts to your brushing behavior by decreasing intensity when you press too hard to protect your teeth and gums.

Real-time pressure feedback via a light ring on the handle flashes to remind you to reduce pressure for safer brushing.

Advanced cleaning performance removes up to 20x more plaque and provides up to 15x healthier gums in just two weeks.

Five specialized brushing modes including Clean for daily use, White+ for stain removal, and Gum Health for gentle cleaning.

A3 Premium All-in-One brush heads help you focus on all areas of your oral health for a complete clean.

Includes a charging travel case for convenient and efficient oral care while traveling.

Quick stain removal helps remove up to 100% more stains in less than two days for a brighter smile.
