Our impression

The 3 Series Sonicare is among the leading performers for Philips in the electric toothbrush segment.

It has been around for quite a while now and we have put it under rigorous tests over the past few months.

As we go ahead with this review remind you of the features that make the 3 Series a great electric toothbrush.

In the process, we also tell you more on how the individual features hold up after a few months of use.

For a start, the 3 Series Sonicare promises 100% better health for the gums if you are still using a manual toothbrush.

The promise of better gums is further substantiated with the ProResults gum care head of the brush.

It is also a deadly weapon against plaque settled below the gumline.

Compared to your standard manual toothbrush, it removes up to 6 times more plaque settled below the gumline.

We will talk about this in detail in a while.

Meanwhile, the 3 Series Sonicare allows you to choose between three different intensity settings.

You can choose between low, medium and high speeds, depending on the type of action you are looking for.

The effect is compounded with the patented sonic mechanism of the Sonicare series, which gives you up to 31, toothbrush strokes every minute.

There is a battery charge indicating panel that lights up in two different colors.

The battery is above decent and it easily lasts you close to three weeks, which is on par with the very best electric toothbrushes.

You may easily consider leaving the charger behind even for longer holidays.

However, the battery compartment is slightly weak and you should not look to open it unnecessarily.

It suffers enough normal wear. Consider opening it only when a change in battery is required.

Sonicare 3 Series

Now the 3 Series is a serious machine as far as caring and cleaning of the gum goes.

The gum health goes up by 100% compared to a manual toothbrush and it remains that way well into the sixth month of use.

If you have suffered from issues like swollen gums, bleeding in gums or even gingivitis, this is a serious brush for you.

You will find remarkable differences in gum health well into the sixth month of use.

In parts, the gum care is supported by the ergonomic handle of the brush.

You can grip the handle very easily and access the three settings for intensity without any major shift in the grip.

The cup-profile of the brush head has been designed for the convenience of those who have just shifted from manual tooth brushing.

It reduces the impact on the gums and drives the bristles deeper between the teeth for more effective cleaning.

You know it is time to have the brush head replaced when the blue reminding bristles start fading away.

The design is Snap-On so you can switch it off easily.

The smart-timer and quadpacer work together to clean all four quadrants of the mouth evenly and in less than two minutes.

The battery charge indicator might appear to be a stock feature.
