When it comes to noise, the Philips Sonicare 4100 is fairly quiet. According to our research, folks say it’s much quieter than a lot of other electric toothbrushes out there. People generally describe the noise as a soft buzzing or a faint hum, which is nice if you're brushing early in the morning or late at night and don't want to wake anyone up.
We don't have a specific decibel count, but our data suggests it's less noisy than many high-powered models. Most people appreciate that it's not too loud while still cleaning effectively.
The Sonicare 4100 uses advanced sonic technology, which helps in reducing noise while still removing up to 7 times more plaque than a manual toothbrush—at least that's what the manufacturer claims.
So, if a quieter toothbrush is what you're after, the Sonicare 4100 should fit the bill without compromising on cleaning power.
