Philips 4100 Series HX3689/44 is a sonic electric toothbrush designed for everyday plaque removal and gentle gum care. The set includes one handle with a built‑in lithium‑ion battery and one brush head. It offers a Daily Care brushing mode, adjustable intensity settings and an integrated timer to support consistent, effective brushing. The toothbrush combines whitening effects with a pressure sensor to protect gums while helping to deliver visibly whiter teeth in one week.

Advantages

The toothbrush uses Advanced Sonicare technology to provide effective plaque removal and gum protection. Two intensity settings let you adjust cleaning power to personal preference, while the BrushSync replacement reminder helps ensure the brush head is changed when needed. A long‑lasting battery enables cordless use for multiple brushing sessions, and SmartTimer with QuadPacer promotes thorough coverage of all tooth surfaces. The built‑in pressure sensor reduces the risk of brushing too hard during whitening and daily care.

How to use

Attach the brush head to the handle, wet the bristles and apply a pea‑sized amount of toothpaste. Select the Daily Care mode and required intensity, place the brush at a 45° angle to the gum line, and guide the brush slowly across each tooth surface. Let the SmartTimer and QuadPacer manage brushing duration and quadrant changes. Rinse the brush head and handle after use and allow them to air dry.

Recommendations

Replace the brush head approximately every three months or when the bristles show wear. Charge the toothbrush fully before first use and follow manufacturer guidelines for battery charging to maintain long battery life.
