The new magnetic driven motor is quieter and the way it works produces a cleaning sensation that is similar, but different. As you move up the Oral-B range, the brushes become more expensive, but they do come with additional features and accessories. We regard these as “nice-to-have” rather than essential.

There is no battery in the case, to charge the brush and anything connected via the USB cable the case has to be connected to mains power.With only a couple of slight differences between these two models, the Pro 3 3000 is the more premium and expensive of the two. But it doesn’t make it the one to go for. Two of the more cost effective models within the Oral-B range of electric toothbrushes, these two are among the most popular models available on the market today and either serve the vast majority of users very well.

Providing you then have the app open on your smartphone or tablet when you go to clean your teeth, the built-in microphones will listen out for the sound of the brush.A smaller and final difference between the two models is the colour of the brush handles, or more precisely the rubber grip that runs down the front of it. I don’t have the figures of the number of oscillations and pulsations on the older Pro 5000 available to give confirmation of the power difference. And add to this, there have been various iterations of the 5000 over the years, so it would be important to find out the exact one to say 100%. The Pro 3 3500 offers the features we regard as essential (a pressure sensor and a timer) at an affordable price. None of these differences affect how well the toothbrush cleans the teeth. They simply affect your experience of using the brush. A smaller, but relevant difference relating to the cleaning modes is that the motor in the Pro 2 2000 is a bit more powerful and actually offers more movements than the Pro 600.
