What it is
Philips Sonicare 3100 (HX3671/33) is a rechargeable sonic electric toothbrush in white. Its high-speed sonic action, about 31,000 strokes a minute, loosens and sweeps away plaque, while a pressure sensor warns when you brush too hard and a smart timer with interval cues guides a full two-minute clean. A brush-head reminder tracks replacement.
Why it's different
Sonic vibration drives fluid between teeth and along the gumline to clean beyond where the bristles touch.
A pressure sensor eases the vibration and signals when you press too hard, helping protect gums.
A two-minute smart timer with 30-second interval cues guides an even, complete brushing routine.
How to use
1. Attach a brush head and wet it, adding toothpaste if you like.
2. Place the bristles at a 45-degree angle to the gumline.
3. Press the power button and guide it tooth to tooth, about two seconds each.
4. Recharge on the base when the battery runs low.

Frequently Asked Questions
Is this authentic?
Yes. We only buy from official retailers and directly from the brands here in Japan. Never resellers, never grey market stock.
We are beauty lovers too, so we know the worry, especially with something you are putting on your face. Authenticity is 100% guaranteed by us.
Will this Japanese model work on my country's outlets?
This is the Japanese-market model, and its charger voltage is not confirmed here, so we cannot promise it works on your local voltage. Check the voltage printed on the charger and in the manual, and use a voltage converter if needed rather than assuming it is dual voltage.
What does the pressure sensor do?
If you brush too hard, the sensor automatically reduces the vibration and gives a pulse cue, prompting you to lighten up. This helps protect your gums and enamel from over-brushing.
How long does one charge last?
A full charge lasts through many days of twice-daily brushing before it needs the charging base again. The battery indicator shows when it is time to recharge.
How often should I replace the brush head?
Every three months is the general guide, or sooner if the bristles splay. The built-in reminder helps track when a replacement head is due.
