Sonic electric toothbrush Philips 3100 series HX3671/11 with pressure sensor, built-in Li‑Ion battery, 1 brush head, white/rose

Philips 3100 series HX3671/11 is a sonic electric toothbrush for adults that combines high-frequency brush movements with a pressure sensor and an integrated timer. Designed for daily oral hygiene, this model uses a built-in lithium‑ion battery and comes with one replaceable brush head. The toothbrush is finished in white and rose and targets effective plaque removal and gentle gum care, offering improved cleaning compared with a manual toothbrush.

Advantages

The sonic technology produces rapid bristle motion to dislodge and sweep away plaque with up to three times better plaque removal than a manual brush. A pressure sensor alerts the user to reduce force, helping to protect sensitive gums and tooth enamel. The integrated timer encourages a dentist-recommended brushing duration, while the rechargeable lithium‑ion battery ensures consistent power without the need for disposable cells. The ergonomic handle and compact brush head support precise brushing along the gumline.

Suitable for

• Daily plaque removal and general oral hygiene maintenance
• Users who need gentle gum care and want to avoid brushing with excessive force
• People seeking a rechargeable, portable electric toothbrush for home and travel
• Adults replacing a manual toothbrush with sonic cleaning technology

Key specifications

• Power source: rechargeable lithium‑ion battery
• Cleaning technology: sonic movement with rapid bristle action
• Pressure sensor to reduce brushing force
• Integrated timer to guide brushing duration

How to use

Attach the brush head securely to the handle and charge the toothbrush before first use. Apply a pea-sized amount of toothpaste and place the brush head against the teeth at a slight angle towards the gumline. Switch the brush on and move it slowly from tooth to tooth, allowing the sonic motion to clean surfaces rather than scrubbing. Follow the integrated timer to ensure recommended brushing time, and stop applying pressure if the sensor alerts. Rinse the brush head and handle after use and store upright to dry.

Usage recommendations

Replace the brush head every three months or sooner if the bristles show visible wear. Maintain routine charging to keep the lithium‑ion battery performing optimally, and consult dental professionals for personalized cleaning technique and replacement intervals.
