The Smart 4 is technically the more capable toothbrush because of the Bluetooth connectivity that it offers.
But, it is the Pro 3 3000 that is my pick.
The Pro 3 can achieve the exact same results, providing you commit to twice daily brushing with the correct technique. It will save you a few pounds too.
Let me talk you through all the key differences, so you understand why I have come to this verdict.

Starting with the handle design and colors, the Smart 4 400 has a larger rubber grip on the front of the handle that the Pro 3 3000 does not have.
The Pro 3 has a smooth touch plastic, with rubber only on the power button.
On the back of the brush handle, the Smart 4 has a series of ridges that run halfway down the handle, compared to the more subtle dimpled texture that runs the full length of the Pro 3 3000 brush handle.
The 4000 is more grippy, but the 3000 is easy to clean.
The Pro 3 is available in 4 different colors, alabaster white, pink, electric blue and black onyx. The Smart 4 comes in 2 color options, white or pink.
The Smart 4 has a white plastic body and the color accent is the rubber grip. Whereas the color on the Pro 3 is the plastic handle itself.
The color of the handle can affect the color of the travel case and even the color of the brush head provided in the box too.
The Smart 4 comes with 2 brush heads included, whereas the Pro 3 comes with just 1.
These 2 heads with the Smart 4 are either both CrossAction or 1 x CrossAction and 1 x 3D White.
The Pro 3 comes with either 1 x CrossAction, 1 x 3D White, 1 x Sensi UltraThin or 1 x Charcoal.
Brush Head Stand
A little extra that the Smart 4 comes with is a brush head stand. This is a white plastic module that clips around the charging stand with 2 prongs on, onto which brush heads can be placed.
It is a simple, yet effective accessory that can provide a neat way to store additional brush heads.
Another slight design difference is that the Pro 3 3000 has a larger and more visible light ring that wraps a full 360 degrees around the top of the brush handle.
This is the visible pressure sensor. It lights up red when activated. Whereas the Smart 4’s sensor is smaller and positioned towards the back of the brush handle.
The most significant difference between these 2 brushes is the fact that the Smart 4 has Bluetooth technology.
You will see the Bluetooth icon on the Smart 4’s brush handle. Using a free app available for Android and iOS you can connect the 4000 wirelessly to your smartphone.
It is far from essential and you don’t have to use it, but take the time to and you might well benefit. Although it does require some commitment.
How it works? In short, it tracks your brushing frequency, brushing time, and any excess pressure you apply. It doesn’t track the exact position of the brush in the mouth.
It won’t tell you that you didn’t brush your back teeth for example.
If you use the app at the same time you brush, you will get an on-screen timer.
Because it logs your brushing sessions, it holds you accountable a bit more as you can see when you have, or perhaps have not brushed.
Finally, the price.
The Pro 3 3000 has a lower retail price of $120 compared to the $160 of the Smart 4000.
However, the retail prices don’t tell the whole story.
It is extremely common for the actual selling price of the brushes to be around 50% less.
This means the prices reduce to $80 and $60 respectively.
Still a difference of $20, but less of a premium given there is too an extra brush head in the box with the Smart 4 and the brush head stand.
Technically the Pro 3 is the best value, but the Smart 4 really isn’t much more expensive if you think you will benefit from the Bluetooth.
Do be aware things are subject to change. Products do get updated and changed by manufacturers. I’ve done my best to ensure everything is correct at the time of writing.
