Philips Sonicare Flexcare Platinum

Philips Sonicare Flexcare Platinum

The Philips Sonicare Flexcare Platinum uses advanced technology to stand out amongst competitors. As the number one toothbrush brand recommended by dentists, the Flexcare Platinum offers a total solution for deep cleaning with its patented sonic technology (view on Amazon).

With 9 different brushing options, the Flexcare Platinum provides a more tailored brushing routine than the 1- or 2-mode models. In fact, Sonicare takes brushing modes a step further by also offering intensity settings. This means that Flexcare Platinum users are fully in control of their preferred brushing modes.

Yet, while electric toothbrushes are becoming more popular, not all features are designed equally. In fact, some toothbrushes can compromise oral hygiene by focusing more on additional features and less on users’ needs.

This Flexcare Platinum review is here to help you decide whether this is the brush for you.

Philips Sonicare Flexcare Platinum Performance

  • Removes up to 10x more plaque than manual brushes.
  • 3 modes with 3 settings to adapt to your needs.
  • 31,000 brush strokes per minute.

How does the Flexcare Platinum toothbrush work?

In contrast to 1-mode brushes, the Sonicare Flexcare Platinum allows users to adjust the brushing experience with 3 modes and 3 intensity settings. Unlike some advanced brushes, the Flexcare Platinum can make the transition from manual to electric brushes easy by letting users choose their intensity level.

To help improve users’ brushing, the Flexcare Platinum uses a pressure sensor to alert users when they are brushing too hard. Importantly, this reduces the risk of enamel damage by ensuring safe brushing. Along with this, the 3 cleaning modes (Clean, White, and Deep Clean) mean that users can switch between everyday brushing and deep cleaning when needed.

7 key features unpacked

1.) Brush per minute

The FlexCare Platinum brush uses sonic technology to produce 31,000 brush strokes per minute. This high brush speed is what makes a sonic toothbrush.

In contrast to other models like PowerUp, which has only 15,000 brush strokes per minute, the Sonicare FlexCare Platinum brush uses more brush strokes per second, which results in a deeper clean.

2.) Brushing mode

The Sonicare FlexCare Platinum brush has 3 cleaning modes (Clean, White, and Deep Clean). Within each mode are 3 intensity settings (low, medium, and high). This means you can adjust the brushing experience to best suit your needs.

3.) Battery life

Unlike rival toothbrush companies like Oral-B—whose brushes have an average battery life of 7 days—the Sonicare FlexCare Platinum has a battery life of 3 weeks. Because of this, users can freely brush without needing to leave the handle on charge.

4.) Charging options

Like most of Sonicare’s products, the FlexCare Platinum toothbrush comes with a travel charger for use on the go.

5.) Brush head replacements

The FlexCare Platinum toothbrush comes with 2 replacement brush heads—1 InterCare brush head and 1 AdaptiveClean. While all Sonicare snap-on brush heads are compatible with the FlexCare model, Sonicare provides 2 options for users to try.

6.) Smartimer

While the recommended brushing time is 2 minutes, the ADA note that the average brushing time for Americans is 45 seconds. With this in mind, Sonicare uses a Smartimer to track brushing times and alert users to the end of the routine.

7.) Quadpacer

Along with the Smartimer, Sonicare also uses a Quadpacer, which pauses in 30 second intervals. This ensures that users reach all sections of the mouth—or “quadrants”—evenly.

The quadrants are as follows:

  1. Top teeth: back left to center
  2. Top teeth: back right to center
  3. Bottom teeth: back left to center
  4. Bottom teeth back right to center

How does the Sonicare FlexCare Platinum toothbrush compare?

The listed models include the Smartimer and Quadpacer. It is also worth noting that while DiamondClean Smart is the costliest, both the Flexcare Platinum and HealthyWhite+ have a longer battery life.

Who is the Sonicare FlexCare Platinum toothbrush suitable for?

  • Those looking for a more tailored brushing experience based on deep cleaning/whitening.
  • Users seeking a brush with adjustable intensity.
  • Those able to afford a high budget toothbrush.

While the FlexCare Platinum has 3 intensity settings for each mode, it is less suited to those who are new to electric brushes. This is because the brushing modes are more advanced and may take some getting used to. However, this brush is still excellent for those looking for low- or high-intensity brushing options.

Reliability and long term use

Generally, Sonicare is praised for its immediate battery life. However, with brushes lasting 1-2 years on average, Sonicare is sometimes criticized for falling short in its longevity. Yet, many still choose to use Sonicare as the brand is reputable and trusted among dental professionals and the immediate battery life outweighs the negatives.

It is worth bearing in mind that correct use of your brush is important. Sonicare recommends charging your new brush for 24 hours before its first use and to avoid keeping it on charge at all times in future.

Sonicare FlexCare Platinum toothbrush warranty and customer support

If you run into trouble using your Sonicare toothbrush you should consider warranty and support options. The FlexCare Platinum model has a 2-year warranty and the following support options are available:

Phone: 1-800-682-7664




The Sonicare FlexCare Platinum toothbrush is ideal for those looking for extra cleaning modes. It is also great for those who are more sensitive to sonic technology and prefer a lower intensity. However, the brush is less suited to those who are new to electric toothbrushes due to its advanced settings.

Because of its modes, the FlexCare Platinum brush targets a wider market than Sonicare’s everyday range as it offers whitening and deep clean options. Overall, the brush is designed to promote even brushing and plaque removal by considering every stage of the brushing process.
