Oral-B Smart 6 vs. 5 vs. 4 – Is Oral-B’s mid-range worth it?

One of the brands we first think of when it comes to oral health is Oral-B. Or, at least, when we think about changing our electric toothbrush, we can’t help but think of this company, whose track record has positioned it as one of the leaders in this market. Today we want to talk to you about three models from the Smart range: Oral-B Smart 6 vs 5 vs 4. Before continuing, it is likely that you will also see them with other nomenclature, such as 6000N, 5000N and 4000N. If you see them with this name, don’t worry, they are the same ones we are going to talk about now.

But, be careful, you should not confuse the electric toothbrushes of the Smart range with those of the iO range. Currently, the iO range is the most technologically advanced of the brand, but we like the Smart a lot because it has a good balance between quality and price. And it is that, unlike the iO, the Smart has more affordable brushes and that have some of the features that we use the most.

For example, the three Oral-B Smart 4, 5 and 6 brushes have such interesting features as the integrated timer, the pressure sensor or the possibility of Bluetooth or app connection. In addition, they have some advantages compared to the iO, since the Smart have several replacement heads.

If you are thinking of renewing your electric toothbrush and you don’t know which one to opt for, read our comparison! In it, we tell you which are the most representative qualities of these three Smart electric toothbrushes so that you can decide with all the complete information.

Oral-B Smart 6 vs 5 vs 4 – Comparison Table

Now, you can see a table in which we collect the main characteristics of the three electric toothbrushes in the Oral-B Smart range:

The design is classic

The three electric toothbrushes in the Smart range have a design that we could define, rather, as classic. First, because in all three cases it is white, except for the Oral-B Smart 6, which combines a white and blue design. Also, because they do not have the interactive screen that we do find in the iO range and which is what gives the brushes a more different appearance. In this case, the design of the brush is more sober and minimalist, with a central button and battery charge indicators at the bottom.

On the other hand, it is interesting to take a look at the number of replacement heads they have. The Oral-B Smart 5 and 6 have 3 replacement heads, while the Oral-B Smart 4 has 2. All of them are Cross Action heads, one of the most common of the brand and which is characterized by its rounded shape and its filaments arranged at an angle of 16 degrees.

Same battery, same charging time

One of the advantages of Oral-B electric toothbrushes is their long autonomy, which in most of their brushes is up to two weeks. In addition, the Oral-B Smart 4, 5 and 6 take approximately the same time to fully recharge the battery, a time that ranges between 8 and 12 hours. In addition, if it is low on charge, the indicator located at the bottom will light up, so that you can anticipate if it needs to be recharged.

How many brushing modes do you have?

This is another of the big differences that we found between the three electric toothbrushes that we have analyzed. The Oral-B Smart 5 and 6 have 5 brushing modes, compared to the 3 modes that the Oral-B Smart 4 has. The first two have Daily Clean, Sensitive, Gum Care, Whitening and Professional Clean modes. For its part, the Oral-B Smart 4 allows you to choose between the Daily Clean, Whitening and Sensitive modes.

Actually, the three modes that the Oral-B Smart 4 has are different and interesting enough to cover the dental hygiene needs of most people. However, it is true that the variety is less, but so is the price.

And, with regard to brushing technology, it should be noted that in all three models it is what Oral-B calls 3D (rotation, vibration and oscillation). It is the most common brushing system in Oral-B toothbrushes, because, according to the brand itself, it is the most effective when it comes to keeping your mouth cleaner. It is true that the Oral-B Smart 5 and 6 increase the oscillations per minute compared to the model 4, but the nature of the movement is the same.

Pressure sensor on all three brushes

One of the qualities that all three electric toothbrushes have in common is the incorporation of a pressure sensor with which we can know if we are applying the right pressure or not. Thus, if you brush too hard, the brush itself will warn you to reduce the intensity, and vice versa.

In fact, brushing is monitored in real time in all three models , which you can check through the mobile app. This is where you can check if you are brushing your teeth well, in which areas, and how you could improve even more. Of course, only the Oral-B Smart 6 has a light indicator on the brush, the functionality known as SmartRing.

Connectivity and Bluetooth

Any of the three electric toothbrushes can be connected to the Oral-B app, from which you can carry out complete and exhaustive monitoring of brushing, as well as check the history of previous cleanings or see what advice the brand gives you to improve your brushing In fact, the ” Personalized Coaching ” function allows you to see suggestions that the app itself makes based on your brushing habits.

As you can see, the fact that the three brushes can be connected with an app is a technological advance compared to other models. However , they are far from the advanced features that those of the iO range have, such as the reminder to change the head, which is not in any of the Smart.

Not all have a travel case

Oral-B electric toothbrushes are perfect for traveling, although the Oral-B Smart 5 and 6 have an advantage in this regard. Only these two are equipped with a travel case, an accessory that the Oral-B Smart 4 lacks and which we find quite useful. We can always incorporate a cover, but the fact that there is already one convinces us a lot because it is more comfortable when transporting.

Oral-B Smart 6 vs 5 vs 4: Which electric toothbrush is more interesting?

After having tested and analyzed the differences between the three models, it is clear to us that the Smart 5 and 6 are practically the same model in which the only thing that changes is the design, which in the Oral-B Smart 6 is bicolor. For the rest of the features, we have not found major differences, except for the SmartRing, the light pressure indicator that is only on model 6. However, the differences increase if we compare them with model 4, which is simpler in all aspects. senses.

It has two less brushing modes, and has one less replacement head. Also, although the brushing movement is of the same nature, the Oral-B Smart 4 brushes somewhat less intensely, because the number of oscillations per minute it carries out is smaller. The good thing about this toothbrush is that it is cheaper and is actually one of the cheapest electric toothbrushes you will find on the market. Of course, it has the guaranteed Oral-B quality seal.

Therefore, the decision on which electric toothbrush to buy will depend, fundamentally, on the maximum budget that you want to spend. From the point of view of functional practicality, the most complete is the Oral-B Smart 6. In fact, we would stay with this model because, despite the fact that its price is higher than that of the Oral-B Smart 4, it is not exorbitant either, and it integrates somewhat more advanced features and functionalities.

On the other hand, if you can’t spend a lot of money, the Oral-B Smart 4 is a simple but effective toothbrush, with which your mouth will stay clean and improve compared to manual brushing. So, as we always tell you, think about what your search priorities and preferences are and you will know which of the three best suits them.
