Oral-B Smart 4 4000 Review

If you are looking for the best value Oral B electric toothbrush with Bluetooth connectivity then the Oral B Smart 4 4000 is the one to have.

It comes as the 4 4000N CrossAction, 4 4000w 3D White and 4 4000S Sensitive rechargeable electric toothbrush.

Basically it is the type of brush head you get that differentiate the naming of one 4000 Smart from the other. All other features as discussed below are the same in all of them.

  • CrossAction is default and most recommended Oral B brush head for normal use

  • 3D Cleaning motion
  • 3 Cleaning modes: daily clean, sensitive and whitening
  • 2 weeks battery life using Lithium-Ion battery
  • 2-year warranty that can be extended to 3 by registering it
  • 2 brush heads: CrossAction and Sensitive

Cons:

  • No travel case included
  • No Smartphone holder

Bluetooth Connectivity

The Bluetooth connectivity is one of the most desired features by people who want to take the teeth cleaning to the next level.

What this feature does is that it let you connect your toothbrush to the app via Bluetooth.

You basically download the app from iTunes or Google Play store, install it on your Smartphone or tablet and use Bluetooth to connect it with your brush.

When it is time to brush your teeth, you put the app on.

What the app does is, it tracks how often and long you brush your teeth, which mouth area do you concentrate more and if you are brushing too hard or not in real-time. It then offers guidance on how to brush your teeth and gums properly.

Pressure Sensor

How do you know that you are brushing your teeth too hard or not? `If you do not know, this is the feature to have.

The Smart 4 has a sensor on its handle that lights up red when you brush your teeth too hard.

With the electric toothbrush, your job is just to guide the brush to do the cleaning. No scrubbing or applying too much effort as you do with the manual toothbrush.

With the help of this feature, it is easy to know how to adjust the pressure you put on the toothbrush.

2 Minute Timer with a Pacer

This brush also comes with a built-in 2-minute timer with a pacer that buzz every 30 seconds to remind you to move from where your brushing to another mouth area.

With a mouth having 4 quadrants, you need to give equal time to each quadrant and the buzzing pacer helps you to do that. The timer is also there to make sure that you brush your teeth within 2 minutes recommended dentist brushing time.

3D Cleaning Motion

In Oral B toothbrushes, there are 2D and 3D cleaning actions. The 2D movement involves rotating and vibrating when brushing your teeth, while the 3D includes pulsating into the movement. With the 3D movement, the brush has the ability to remove up to 100 per cent tooth plaque (https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/605266/Delivering_better_oral_health.pdf) than the 2D action found in the low end, cheaper toothbrushes.

Good news, the 4000 Smart offers this advanced 3D cleaning action where you teeth are being cleaned side by side and up and down while stimulating the mouth to produce more fluids to dissolve hard to reach dental plaque.

3 Cleaning Modes

The cleaning modes are aimed at helping you achieve different cleaning needs. The 4000 comes with 3 modes:

  • Daily clean mode, this is the mode in which your teeth are being cleaned at full power, high speed to remove plaque. It is a default mode for all Oral B electric toothbrushes.
  • The sensitive mode is to be used in times of having sensitive teeth and gums.  If your gums are inflamed and your teeth very sensitive, buying a sensitive brush head with soft bristles to be used along this mode will offer you the best result.
  • Whitening mode as the name goes is for whitening the teeth by not only removing plaque but also scrubbing the surface stains. For better results, you need to buy also a 3D white brush head. The 3D white has a whitening cup on the brush head for polishing the teeth and makes them white.

You change from one mode to the other by pressing the switch on and off button several times while the brush is on your mouth. You just need to remember the order of the modes: daily clean, sensitive then whitening.

The first time you switch on you get the daily clean mode, next switch the sensitive mode then next whitening mode.

2 Weeks Battery Life

The 4000 Smart Electric Toothbrush Rechargeable comes with an improved battery ‘Lithium-Ion battery’ that last longer than the old ‘Nickel Hydride battery’ found in the low-end Oral-B models. The Lithium-ion battery can last up to 2 weeks time compared to 5 to 7 days of the Nickel Hydride.

However, there are people who are still lamenting of their batteries not lasting long. Others recommend that buying the 4000N CrossAction electric toothbrush is the one that comes with a Lithium-ion battery and others come with a Nickel.

Otherwise, the battery flashes red when needs charging, sparks green when it is charging and no flashes when it is fully charged.

You get a charging station that runs on 220 to 240 volts and a 2 pin plug than needs you to connect it on your shaving socket in the bathroom or alternatively buy a 2 to 3 pin adaptor. The station can hold up to 2 toothbrush heads at the time.
