Oral B Genius Pro 7500 vs 8000 Electric Toothbrush: Ultimate Comparison

We clean our teeth every day, often without really thinking about it. But those two minutes a day, twice a day, mean that over the course of your life, you will brush your teeth for nearly 120,000 minutes, or a little over 82 days.

To give you some perspective, that means you can watch every episode of Friends 23 times (which some of you might have done). That’s a lot of time for you to be wearing away at the only set of teeth you have.

Once the adult ones come through, you’re not going to grow any more, which is why it is so important that you choose the best toothbrush you can. But how do you decide which is the right one for you?

We have no doubt that if you’ve been on our planet for more than a few years, you’ll have heard of Oral B. And we are used to hearing their brand name followed by the statement that they are the “Number 1 brand used by dentists worldwide.”

This claim is based on surveys done across many countries, so it seems like Oral B really is one of the best brands out there for taking care of your teeth. The question is, which toothbrush is the right one for you?

Dentists have been recommending that we all get electric toothbrushes for years. They suggest that not only do electric toothbrushes manage to achieve more brush strokes, but they can also be really helpful with applying less pressure.

We’ll get into this later in the article. But given that they are the standard-setters for oral hygiene, it is no wonder that Oral B has a wide range of electric toothbrushes. In this article, we are going to compare two of their higher-end electric toothbrushes, the Genius 7500 and the Genius 8000.

We’ll also highlight some of the key features that you should look out for when purchasing a new toothbrush, so you’ll be able to decide what’s best for you with all the information you need.

We’ve put together a quick list of the main advantages and disadvantages of each toothbrush here, in case you don’t have time to read the full article.

But if you are going to buy one of these brushes, then we recommend that you read the full article, so that you can know the details of what you are getting.

What’s The Difference Between Them?

Both of these electric toothbrushes are top-of-the-line options. They are only one generation apart and they are both really fantastic, and pretty futuristic, options. In fact, there are more similarities than differences between them.

So we’ll take you through a lot of their key features, like the battery life, brush-heads, settings, pressure-sensors, and price. But first, let’s take a look at their designs.


If you’ve never had an electric toothbrush before, it can feel a little heavy and difficult to maneuver. But once you get the hang of them, they’re actually way easier to move, largely because the brush does all the work for you, so you can just hover it on each tooth, rather than scrub all over.

Both of these Oral B electric toothbrushes have a pretty standard design. They have a larger, cylindrical base, with a detachable brush head. We’ll go into the brush heads below, so for now, we’ll concentrate on the brush handle.

They each have a simple power button, near where the thumb would naturally rest, plus they have a button to help you pick which power setting you want. Again, we’ll get into the power settings available later in the article.

However, suffice to say that they each have a little symbol that lights up, to indicate which setting you are on. Plus they have a battery indicator, so you can make sure that your toothbrush won’t die mid-brush.

Above the power button, both of the brushes have a multicolor SmartRing, which again, we’ll explain about below. The 7500 is a little smaller than the 8000. It measures 3.98 x 7.67 x 9.96 inches, whereas the 8000 measures 4.01 x 9.25 x 9.96 inches.

However, the 8000 is lighter, weighing around 13oz, compared to the heavier 16oz of the 7000.
The 8000 also has an extra color option to that of the 7500. Both toothbrushes are available in black or white, plus purple or gold.

However, the 8000 is also available in pink. Having the toothbrush available in a variety of colors is a really nice touch for anyone who is purchasing for the whole family.

No one wants to reach for their toothbrush and find out they’ve got dad’s brush in their mouth! So if you’ve got a larger family, the extra color option of the 8000 could be useful.

The two toothbrushes have very similar designs, but as the 8000 is a little lighter and has an extra color option, it would be our pick in terms of design.

One of the main reasons for investing in an electric toothbrush is that it comes with different cleaning modes. It might seem strange, especially for anyone who is upgrading from a manual toothbrush, but it can be really important to address different aspects of your oral hygiene by picking different settings.

Both toothbrushes have a daily clean mode. This is perhaps the one that you would use as a standard setting. It should be enough to handle the plaque and tartar control, to help stop your teeth feeling fuzzy and prevent plaque from building up and turning brown or yellow on your teeth. Although you should remember that you always need to floss too. Both brushes then also come with a pro-clean mode.

This setting is more powerful, and is better to be used on the odd occasion (probably just before you have a dentist appointment), to give your teeth a more thorough clean. But as it is more powerful, you probably don’t need to use it every time. Similarly, they both have a whitening mode. Best suited for the odd occasion, this probably shouldn’t be your setting for every clean, but it will help your teeth to sparkle when you need it.

The two toothbrushes also come with a gum care mode. There’s a good chance that you haven’t thought that much about your gums, unless your dentist has mentioned them, but looking after the gums is essential for good oral hygiene.

Gum disease is usually painless, but it can lead to the gums pulling away from the teeth, swelling or bleeding, and even tooth loss. The cause is often that plaque has been left to get worse.

But the best way to treat it is with a less intense setting, while approaching the gums at an angle. Take it easy though, they really don’t need much power, so make sure you use the gum care mode for this part of the routine.

Another setting that they share is the sensitive mode. Teeth are often sensitive because of enamel wearing away, which leaves nerve endings exposed. When your nerves are exposed to the hot and cold, whether in food, beverages, or air temperature, they feel aggravated.

The best way to prevent this is by not brushing too heavily and taking it easy. For some people, the sensitive mode might be the best one to use all the time, especially if you’re heavy-handed. The pressure sensor, which we’ll look at below, is another great way to keep this in check.

Finally, the 8000 also has an additional setting, which is the tongue cleaning mode. Cleaning the tongue can be a tickly experience, but it is really important to address the hidden bacteria and dead cells that can lie on the tongue.

Removing these is a key aspect for preventing bad breath, plus it can help to make your food taste better, so it’s well worth remembering to give your tongue a scrub.

Again, the two toothbrushes are pretty similar in this regard, and they are both head-and-shoulders above so many other electric toothbrushes on the market, but as the 8000 has the extra tongue cleaning mode, we’ll give this round to the 8000.

If you want to get the right brushing experience for your own mouth, another aspect to consider is the brush-heads. As electric toothbrushes have detachable, replaceable, brush-heads, you don’t have to commit to just one forever. Instead, you can try different ones depending on your current needs.

Each of these two brushes comes with three different brush heads: CrossAction, FlossAction and 3D White. The CrossAction head is set at a 16º angle and the brush fibres go in opposing directions around the brush, to help get deep between the teeth.

The FlossAction is a brush-head that shouldn’t replace flossing, but should be better at reaching some of the hard-to-reach places, which in turn should help to keep your teeth and mouth healthier.

Finally, the 3D White brush-head works best at removing surface stains, thereby creating whiter teeth from day one.

The two brushes are identical when it comes to brush heads, and both can use a variety depending on your needs.

One of the key aspects that worries people when it comes to an electric toothbrush is the battery life. No one wants to reach for their toothbrush and find out that they can’t use it. Of course, in that situation, it could just be used without charge, like the old toothbrushes, so it wouldn’t be the end of the world, but it’s no ideal.

Luckily, neither of these brushes will have that difficulty. They both last for fourteen days of cleaning after just one charge. It is worth mentioning though that the brushes take quite a few hours to reach full charge.

So if you are going to be away for more than a week, make sure that you leave enough time to fully charge it before you go. However, if you are going to take it with you to places, both of these brushes are a pretty good option, as they both come with travel cases.

If you’ve ever lost your toothbrush in your bag and pulled it out later covered in hair, dust, and lint, you’ll know how useful a travel case can be. The 8000 is actually a USB charging case, so you can easily keep it charged while you’re away.

The case can even charge your phone as well if you need, although this seems a bit pointless to us, but who knows. Maybe it’ll be just what you need.

The two toothbrushes each have a battery life of two weeks, but the charging travel case just edges the 8000 into the lead for this round.

You might have thought that you knew how toothbrushes work, but these two brushes have both stepped up and taken it to the next level. As we mentioned earlier, they each have a 360º smart ring around the top of the brush handle.

This smart ring works as a pressure sensor, so you can tell if you are brushing too heavily via a flashing red light, visible from all sides. However, the brushes both also have an in-built bluetooth system, which means that you can then track your cleaning on your phone.

This can be really useful if your dentist has told you to be careful of certain aspects that you want to monitor, or if you want to show your dentist how you brush to get feedback.

The 8000 has taken this technology even further. The SmartRing has a customizable multicolor system, so that you can get real-time visual coaching on your brushing time and pressure. This means you really should have no excuses about keeping your teeth clean.

We should mention that they also each have the in-built timer, which is fairly standard across electric toothbrushes.

They both let you know when your two minutes is up, as well as keeping you informed each thirty seconds, so that you can make sure you spend enough time on each quadrant. If you aren’t going to use the phone tracking technology then this can be a simpler way to monitor your brushing in real-time.

The technology in both of these brushes is excellent, but the 8000 is just that bit more high-tech and wins this round.

Okay, so you’re probably all thinking, well the 8000 has won each round, but what’s the difference when it comes to price? Well, it’s actually not as much as you might have thought. Both of these options are premium electric toothbrushes, so although prices do vary, they are both over $100. But while the 7500 is around $120 as we write this, the 8000 is around $140.

That means that there is a $20 price-difference. For that price, you get the upgraded travel case, an extra color option, an extra tongue-cleaning mode, and a more customizable cleaning experience that you can monitor from your phone. If you’re not going to use these features, the 7500 is clearly the better choice, but $20 isn’t much for those extra upgrades.

When it comes to price, the 7500 is the definite winner at $20 cheaper.

Well, we’ve now shown you both the brushes in detail. They each last for 14 days, let you know at thirty-second intervals and when your two minutes is up, plus they have a clear display panel to let you know which setting you are on.

They both have clearly-visible pressure sensors, which is an essential feature for a lot of people, and they both have a lot of different cleaning settings, so you can get the clean you need.

But the 8000 does have quite a few upgrades which, although they’re small, would provide a better teeth-cleaning experience overall, in our opinion. However, our opinion isn’t important. What matters is which one works best for you.
