What is the Sonicare Protective Clean 4100? 

Philips Sonicare 4100 Electric Toothbrush

The Philips Sonicare Protective Clean Plaque Control 4100 is one of the top-selling electric toothbrushes in the world. 

There’s a good reason for this. Along with Oral-B, Sonicare has long been favored by dental professionals for the superior cleaning experience of its products. 

These features include:

  • Two-minute timer to ensure adequate brushing time
  • Interval pacer that prompts you to move to the next section of your mouth
  • BrushSync to let you know when to replace your brush head
  • Pressure sensor that vibrates to alert you to excess brushing pressure

These features, particularly the timer and pacer, are key to the value of an electric toothbrush. 

Dental professionals agree it takes two minutes to brush your teeth adequately.1 However, most Americans only brush for 45 seconds, leading to plaque buildup and cavities.4 The pacer and timer ensure good brushing habits.

One problem many people encounter when switching from a manual toothbrush to an electric is improper use. People either brush too hard or fail to replace the brush heads when they get worn out. Both can damage enamel and cause oral health issues.6

Pressure sensors and a reminder system like BrushSync help prevent these issues. These are just as important as the timer and pacer, but less common, providing the 4100 added value.

A Sonicare Protective Clean 4100 kit comes with the following:

  • Rechargeable brush
  • One brush head 
  • Charger cord
  • Charging base

The American Dental Association (ADA) has given the Protective Clean 4100 its Seal of Acceptance, meaning the brush can effectively remove plaque and prevent cavities.1

Anyone looking to upgrade from a manual toothbrush will find the Protective Clean a good option. The brush has many essential features needed in an electric toothbrush, as well as some helpful extras.

Sonicare Protective Clean 4100 vs Oral-B Pro 1000

The Sonicare Protective Clean 4100 compares well to the Oral-B Pro 1000. Both brushes come with the ADA Seal of Acceptance and will clean your teeth exceptionally well. However, each comes with its own advantages.

Here’s where each brush excels:

Design: Sonicare Protective Clean 4100

Sonicare has always emphasized aesthetics slightly more than Oral-B, and the Protective Clean is no exception. 

The Protective Clean is pleasing to the eye, in contrast to the relatively clunky-looking Pro 100. In addition, the Sonicare brush is also much quieter, whereas the Pro 1000 is quite noisy.

In Oral-B’s favor, the Pro 1000 weighs slightly less — just under half a pound — than the Protective Clean’s 0.79 lbs. 

Cost of Ownership: Oral-B Pro 1000

The Pro 1000 costs less in terms of both the retail price and long-term ownership. On Amazon, the Oral-B is currently selling for $40. Meanwhile, the Protective Clean retails for $70 — a significant difference.

The cost of replacement heads also varies for the two brushes.

An official brush head for the Protective Clean costs $9 ($1 for generic). The Pro 1000 brush head costs significantly less at $5.50 ($0.75 for generic).

The Oral-B is a more affordable brush in the short- and long-term.

Battery Life: Sonicare Protective Clean 4100

The Protective Clean has two weeks of battery life on a full charge. This is more than Pro 1000, which lasts anywhere from a week to 10 days. 

Some reports have even placed the Protective Clean’s battery life at well over two weeks, but even with the official stats, the Protective Clean has a significant advantage.

Brush Head Size: Oral-B Pro 1000

Oral-B brush heads tend to be smaller than the oval brush heads favored by Sonicare. These toothbrushes are a bit easier to maneuver in your mouth. 

Many people, especially those with small mouths, say they find Oral-B toothbrushes more comfortable to brush with.

Features: Sonicare Protective Clean 4100

The Protective Clean offers more features than the Pro 1000. In addition to BrushSync, its pressure sensor also emits a noise to alert you when you’re brushing too hard. 

The Pro 1000 also has a pressure sensor, but it’s silent. It only slightly reduces the intensity if you press down too hard.

The Protective Clean 4100 also comes with EasyStart, which slowly ramps the vibration intensity over the first two weeks of ownership. This is ideal for electric toothbrush beginners, who may find the intensity of the vibrations a bit overwhelming. 

Bottom Line

Overall, the Sonicare Protective Clean 4100 is better-designed and slightly more advanced than the Pro 1000. However, the Oral-B is also a good choice due to its lower cost and slightly more comfortable brushing experience.

Is the Sonicare Protective Clean 4100 Toothbrush Right for You? 

If you’re looking for an electric toothbrush with slightly more features than a strictly level model, the Sonicare Protective Clean 4100 is a good choice. It has all the essentials plus some helpful additions other brushes in its price range don’t offer.

The brush comes with just one cleaning mode (called Clean Mode). This is fine for its price point since the 4100 is a basic Sonicare model. It makes the brush simple to use and is all most people will need.

However, more experienced users may find this off-putting. Those with small mouths or sensitive teeth might also want to consider alternatives like the Sonicare Essence.

What Customers Are Saying

The overwhelming majority of Amazon reviews for the Protective Clean are positive. Most praise is directed toward the various helpful features like the timer, pacer, and pressure sensor. 

Negative reviews of the 4100 focus on the intensity of the vibrations. The 4100 vibrates at 31,000 brush strokes per minute (BPM). This can be overwhelming for someone used to manual or even electric toothbrushes.

It’s unclear how many of these users took advantage of EasyStart, but this is something to keep in mind.
