Product Information

Full details

The Philips Sonicare 2100 Series is designed for adults transitioning from manual brushing who want a more efficient cleaning experience. Its key benefit is the advanced sonic technology that removes up to three times more plaque than a standard manual brush while remaining gentle on gums; however, it features only a single brushing mode, which may lack the customization options preferred by advanced users.

The brush features a battery level indicator that will alert you when it is time to recharge.

Does it come with a travel case?

Setup, Compatibility & Care

Setup: Charge the toothbrush fully before its first use. Because it uses a DC5V power source, ensure your charging adapter is compatible. The brush comes with one head included; simply snap it onto the metal shaft until it is secure.

Compatibility: This unit works with a wide range of Philips Sonicare click-on replacement brush heads. Always ensure you are using genuine Philips heads for optimal performance and to avoid damage to the handle shaft.

Care: After every use, rinse the brush head and bristles thoroughly. Once a week, wipe the handle with a damp cloth to remove any toothpaste buildup. Do not submerge the handle in water for extended periods, and ensure the charging base is kept in a dry area.
