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 Oral B toothbrushes.
Good news, the Oral B Smart 4 4000 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 Oral B Smart 4 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 Oral-B Smart 4 4000N CrossAction 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 Oral B Smart 4 400N 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.
