Visible Pressure Sensor

Like most mid-range and high-end Oral B electric toothbrushes, this toothbrush also comes with a ‘visible pressure sensor’ located on the rear-side of its handle. It illuminates red colour when you brush your teeth too hard.

Every time you see the red flash remember to reduce the pressure you apply on your teeth. For an electric toothbrush, you need just to guide the brush do the manual work for you.

2 Minute Timer with Quadpacer

The brush comes with the built-in 2-minute timer with a pacer that buzzes after every 30 seconds to alert you to move into another mouth area.

As you already know, the mouth has 4 quadrants. You need to spend 30 seconds on each area and the pacer will help you achieve that.

The timer itself is for helping you achieve a 2 minutes dentists recommended brushing time.

Travel Case

Compared to the Oral B Smart 4000 that has no travel case included, this brush, on the other hand, comes with a standard plastic travel case. The case can hold one toothbrush and 2 brush heads.

Charging Station

You get a charging station with a 2 pin plug to be connected on your shaving socket. Alternatively, you can also buy a 2 to 3 pin adaptor.

Bluetooth Technology

The Bluetooth technology is one of the main features in all Oral-B electric toothbrushes ranging from the Oral B 4 Smart onwards.

This feature is not for everybody but for people who are serious with the need to improve their dental hygiene.  The Bluetooth helps you to connect your brush with Oral B app, using your Smartphone.

When connected the app shows the real-time data on how you brush your teeth, how often, how hard, how long and which area you concentrate more and offer you proper teeth cleaning guidance. There is a screen timer that shows you where to brush and if you have brushed well.

The best part, you also get a phone holder that you can use to put your phone while using the Bluetooth, rather than holding the phone on one hand while brushing.

Your brushing habit is also recorded in a calendar where you can view over a period of time and make an adjustment to your brushing habit as feels necessary.

Battery Indicator

While the low-end Oral B toothbrushes do not include a battery indicator, this brush includes one.

What this feature does is that it alerts you when the battery needs recharging by flashing red, green when charging and no flash when the battery is fully charged.

Charging the battery takes up to 24hours time.

3 Brush Heads

You get three Oral B electric toothbrush heads:

• Cross action brush head for daily use
• 3D White for using it when using the whitening mode to polish your teeth  and the
•  A sensitive brush head that to be used with the sensitive cleaning mode for brushing sensitive teeth and gums

The brush heads have blue indicator bristles that fade to pale blue alerting you to change or buy a new brush head.

Cons:

Like any Oral B toothbrush, the 5000 Smart is also a bit noisier than Philips Sonicare electric toothbrushes.

Oral B Smart 5 5000 vs 5 5950N
