Many Philips Sonicare ProtectiveClean 6100 reviews rank it in the middle of the field. It’s better than the Sonicare ProtectiveClean 5100 and Oral-B. But most reviewers rank it below the Oral-B Pro 1000 electric toothbrush.

Still there’s no denying that the ProtectiveClean 6100 brush is a very good model.

It performs brilliantly on any objective assessment of teeth cleaning, and gets rid of most dental plaque. However, some users don’t like how it is clunky and hard to use. The clincher for many is the value for money computation. The ProtectiveClean 6100 electric toothbrush is priced a bit higher than other competing brushes.


  • offers 3 different brushing modes
  • BrushSync tells you when to replace worn out brush heads
  • includes pressure sensor to avoid teeth and gum damage
  • battery life is excellent


  • slightly uncomfortable to use
  • costlier than other comparable models

2. What other models are just as good as ProtectiveClean 6100?

The earlier ProtectiveClean 5100 has consistently topped several best electric toothbrush reviews lists for good reason. It has almost the same range of features and options as the ProtectiveClean 6100. It also delivers almost similar performance.

For a top of the line deluxe experience, the Philips Sonicare DiamondClean Smart electric toothbrush is a great alternative to the ProtectiveClean 6100… even if it is a lot more expensive.

Should you consider one of them over the ProtectiveClean 6100? That depends upon your unique needs and requirements. You may find the electric toothbrush buying guide of some help in making this decision.

3. Where can you buy the ProtectiveClean 6100 electric toothbrush?

The ProtectiveClean 6100 electric toothbrush isn’t as great at cleaning as the best electric toothbrush of 2021 – the Oral-B Pro 1000. But it is gentler on teeth and gums. This makes it a far better option than the Oral-B 1000 for those with sensitive teeth and gingivitis or periodontal problems.

And while the ProtectiveClean 6100 is a bit more expensive than comparable models, it has a great battery life. There are also a range of other features to justify this price difference.

Any good ProtectiveClean 6100 review should break down an analysis of the electric toothbrush by various facets of performance. We will address the functions and features of Philips Sonicare ProtectiveClean 6100 under 4 heads.

Comfort and User Experience

Philips Sonicare ProtectiveClean 6100 User Experience

How comfortable is the ProtectiveClean 6100 to brush with?

Most users initially find the Sonicare 6100 a bit uncomfortable to use because it is clunky and slightly thicker. However, 6 out of 10 users say they like how comfortable it is. Even the other 4 quickly got used to it.

Where the ProtectiveClean 6100 knocks out other competitors is with users who have sensitive teeth or gums. Almost all of them loved to use this model because it is gentler and kinder to their sore gums.

Even if this gentle brushing leads to a less effective plaque removal, they find this a very acceptable tradeoff because they can brush teeth more regularly without pain or discomfort while using the ProtectiveClean 6100.

It is also less noisy than other electric toothbrushes, with an inbuilt pressure sensor slowing down automatically whenever you press too hard. Both add to the comfort of brushing with the Philips Sonicare ProtectiveClean 6100.

Easy Start is a unique function for first time users, where the power and intensity of cleaning starts out low and gradually increases over a 2 week period. This is because the full 31,000 stroke intensity can be intense for those who haven’t used this device before.

Cleaning the brush handle after use is a little difficult.

Appearance and Design

The brush handle is sleek and sturdy, slim without being clunky. You’ll get a firm grip on it while cleaning, which is helpful when the handle turns slippery. Some find the clutter of buttons on the handle a problem.

The brush head is inclined at a slight angle to allow easier access to the space behind the last molars.

The Sonicare ProtectiveClean 6100 comes with a range of color options which makes it appealing to users. Instead of being stuck with a clinical White, you can buy this electric toothbrush in 5 distinct colors –

  • Pastel Pink
  • White Silver
  • Navy Blue
  • Black
  • Deep Purple

Some of these models come with colored brush heads, charging stands or travel cases to match. The design and technical performance is otherwise identical.

A power button turns the device on and off. Another button regulates the brushing intensity. Pressing this repeatedly cycles through different intensity settings.

Three LEDs arranged horizontally indicate the intensity. Another series of vertically aligned LEDs tells you what cleaning modes are available – Clean, White and Gum Care.

An indicator to show battery charge levels is near the bottom, and flashes to indicate when it is time to recharge. A neat design touch is a tiny ridge at the bottom of the handle which prevents the brush from rolling off a counter when placed lying down.

A metal shaft sticks out from the handle over which the brush heads can slot. Heads can be easily replaced by tugging them out, and snapping on a replacement head.

A compact, hinged travel case of strong plastic lets you conveniently and neatly pack the Sonicare ProtectiveClean 6100 toothbrush for trips. There is room for a brush handle and 2 brush heads.

In The Box

Philips Sonicare ProtectiveClean 6100 review

You’ll get the following components:

  • Philips Sonicare ProtectiveClean 6100 electric toothbrush
  • 2 replacement brush heads
  • travel case
  • charging stand
  • warranty
  • user manual

Cleaning Performance

The Sonicare ProtectiveClean 6100 offers 3 different cleaning modes – and you can adjust brushing intensity to alter the power intensity delivered to the brush head. You can select between three settings – low, medium and high.

  • Clean mode is a 2 minute cycle for thorough cleaning
  • White mode is a 2 minutes and 30 seconds cycle to polish front teeth
  • Gum Care mode is a 3 minute session, including 1 to massage gums

An inbuilt two-minute timer makes sure that you comply with the dentist-recommended duration for cleaning teeth. Automatic power off functionality limits battery life by shutting down the brush after a cleaning session ends.

A quad pacer included in the Philips Sonicare ProtectiveClean 6100 indicates when it is time to move to another quadrant. This helps make sure that you clean all areas of the mouth equally.

A pressure sensor limits the amount of force you can use while brushing. When you press down too hard, the sensor detects the problem and turns off power to the motor. But unlike other Sonicare models, there is no visible indicator that glows red. This helps avoid injury to sensitive teeth and gums.

Effective At Plaque Removal

The Sonicare ProtectiveClean 6100 electric toothbrush removes most dental plaque on several tests. Some have claimed, though, that in hard to reach areas like the inner surface of teeth or back molars, a bit of plaque still remains.

BrushSync is a technology that’s designed to let you know when the brush heads are frayed and need replacement. Another advantage is ‘mode pairing‘, where the Sonicare ProtectiveClean 6100 toothbrush  automatically sense the kind of brush head you are using, and adjusts the cleaning mode to match it. This helps achieve the best cleaning results. Of course, a user can override these automatic selections.

To avail of this functionality, the brush heads also must be BrushSync compatible. You can however continue to use the device with a standard brush head, except that it will mean missing out on the BrushSync benefits.

Here are the types of brush heads that have this feature:

  • W2 Optimal White
  • Optimal Gum Care
  • Optimal Plaque Defence
  • Premium White
  • Gum Care Premium
  • Premium Plaque Defence

While this range of features make the Philips Sonicare ProtectiveClean 6100 an attractive model, there is still very little to clearly differentiate it from other models in the range.

This is why, because of the price constraints, many buyers find it hard to justify purchasing the 6100 from a ‘value for money’ perspective.

Battery Life of Sonicare ProtectiveClean 6100

The final variable that determines whether or not the Sonicare ProtectiveClean 6100 is a good electric toothbrush for your needs is the battery life.

Like any Philips Sonicare electric toothbrush, the lithium-ion battery technology of the Philips Sonicare ProtectiveClean 6100 is excellent. But because of the range of cleaning options available, the operating longevity of the battery on a full charge is a little under 3 weeks of regular use.

This is somewhat less than other models like Sonicare Essence and Sonicare DiamondClean, though superior to almost all Oral-B electric toothbrushes.

Even if you travel frequently, an electric toothbrush that holds charge for 3 weeks is good enough for most users. In the event your usage is heavy and the battery runs out, you can always carry a charging station along.

The battery is rechargeable, but cannot be removed or replaced by a user. Charging is by placing the device on the base of a charging station, which is attached by a cable to power outlets. A prong on the base fits into the bottom of the brush handle.

Charging is through induction and can be safely performed even in damp environments.

A full recharge takes 24 hours. The battery indicator LED flashes to indicate low charge. When fully charged, the indicator glows green before switching off.

Where To Buy The Sonicare ProtectiveClean 6100

Philips Sonicare ProtectiveClean 6100 review

Many a Sonicare ProtectiveClean 6100 review tries to convince you to immediately click on a link and purchase the device right now. While there’s good reason to buy your electric toothbrush online, you could also pick one up at a neighborhood retail outlet.

It’s always nice to get a deal or discount on anything you buy. And for an electric toothbrush that’s priced around $100, being able to get 20% off is a nice saving.

Strange as it might seem, online retail outlets seem to have perpetual deals going on. This means you can typically get a Sonicare ProtectiveClean 6100 electric toothbrush from Amazon or another e-commerce website – and pay 20%, or even 50% less with a coupon or special offer.

Part of the reason is that these outlets don’t have exorbitant costs of maintaining a showroom or hiring staff or stocking expensive inventory. So they pass on their reduced costs to you in the form of a discount.

You might do well to order the Sonicare ProtectiveClean 6100 from Amazon, especially if saving a sizable amount is of value.

You might also get some extra accessories thrown in instead of a price discount, which eventually works out to a similar saving. If you get 2 replacement brush heads for free, you’ll save around $20 on buying them separately.

Durability and Warranty

Any mechanical and electrical device has a limited shelf life. No manufacturer guarantees perfect performance forever. But the durability of a Sonicare ProtectiveClean 6100 toothbrush is extremely good, and your purchase comes with a Philips Sonicare warranty that safeguards your purchase against technical defects.

As long as you use the device in accord with the manufacturer’s specifications, you have little cause for concern. And in the rare event that there’s a malfunction, your warranty ensures that you’ll get a replacement from the company.

  • Height: 19 cm
  • Head: 6 cm
  • Width: 3 cm
  • Thickness: 3 cm
  • Weight: 132 grams
