Our Analysis and Test Results
This model finished right behind the Sonicare Series 2 and ahead of the Sonicare DiamondClean. The Pro 8000 cleans about the same as the DiamondClean and a bit better than the Series 2. However, the Pro 8000 is less comfortable than both of these brushes and has a shorter battery life than the Series 2. The Series 2 is the least expensive of this group, having a list price about $110 less than the Pro 8000 and $130 less than the DiamondClean.
We spent over 120 hours testing these products to determine which ones were worthy of awards. We split our testing process into four weighted metrics, conducting over a dozen individual tests to determine scores. Each model received a score for each metric, which was then aggregated into the overall score. We detail how the Pro 8000 did in each metric in the following sections, looking at what it did well and where it fell a little flat.
Comfort is our most important metric, responsible for 40% of the total score, as an uncomfortable toothbrush can make your teeth cleaning experience so unpleasant that you won't want to use it. Regardless of how well your electric toothbrush cleans, it won't make a shred of difference to your dental hygiene if you don't use it. We rated these products on how comfortable they are to brush with, if there is an over-pressure sensor, and how loud each model was. The Oral-B Pro 8000 didn't do the best in the metric, earning a 5 out of 10 for its uninspiring performance.
This model felt great to hold in your hand but had some severe drawbacks when it came to brushing. The rotation-oscillation brush head does a fantastic job of cleaning, but it was exceptionally rough on the gums.
One of our testers with more sensitive gums had to quit using it, as his gums were in excruciating pain — even using the brush in its most sensitive mode. Other testers, especially those with smaller mouths noticed that this brush head was much more uncomfortable when brushing the back molars, mainly due to it being approximately 33% deeper than the side-to-side style brush head.
This model was also on the noisier side, measuring in at 78 dBa taken 2" away from the mouth when brushing. Testers also noted that this brush sounded louder and more mechanical when being used, compared to the softer buzzing from the side-to-side models.
The Pro 8000 does have a pressure sensor, slowing down the brush automatically if it detects you are pressing too hard.
Our cleaning metric is next in terms of significance, accounting for 30% of the total score. The Oral-B Pro 8000 did very well in this test, tying for the top score with an 8 out of 10.
Our plaque removal test consisted of having a panel of testers wait at least 12 hours since they last brushed their pearly whites, consuming as much sugary food as they could over that span of time. Each tester then used a plaque disclosing tablets per the manufacturer's instructions, nicely staining the accumulated plaque from eating all of those donuts bright pink. They then brushed with the Pro 8000 for two minutes, and we compared the results with before and after photos.
This model removed almost all the visible stained plaque for every single one of our testers and was either the most effective toothbrush, or second-most effective toothbrush for each of them.
Our panel had mixed genders and ages, and the only common issue with this brush was the difficulty to reach the molars furthest back for those that had more petite mouths. These scores were all based on the first or second time for each of the panel using this brush, meaning that it was exceptionally easy to clean all of your teeth, as they had no experience with this brush and no preconceived plan to pay attention to trouble spots.
Ease of Use
Next, our Ease of Use set of tests is responsible for 20% of the total score of each brush. We assessed how easy it was to use these products, basing our scores on their interface, how easy it was to clean the brush, and the number of brushing modes available, as well as if there is a timer and if additional brush heads had a place to be easily stored. The Pro 8000 scored quite well, earning a 7 out of 10.
This model was well-received by our panel when it came to aesthetic appeal, appreciating the sleek exterior and the easy to understand icons on the front of the brush.
These icons show the different brushing modes, which this brush has six — Daily Clean, Pro Clean, Sensitive, 3D White, Gum Care, and Tongue Clean. This also made it very clear which brushing mode you were using, and the interface to switch between them was very easy to operate. The Pro 8000 also has a two-minute timer, buzzing every 30 seconds to alert you to move onto the next quadrant of your teeth.
This toothbrush was very stable off of its base, with almost every other toothbrush toppling before this one. However, it was much less stable on the base — the larger toothbrush on the small base made it top heavy and easily tumbled. This model also includes a charging travel case.
This drastically changed when the extra brush holder, with a 4 brush head capacity, was installed on the base, making it almost impossible to tip over. The technology behind electric toothbrushes has improved to the point where these products are packed full of various features and functions, including smart connectivity, like the Pro 8000 has. Unfortunately, this one one of the main issues that we found with this brush — especially with the new position sensing feature.
We didn't find this to be the most accurate, with the app mistaking what section of the mouth we were brushing at the time on a frequent basis. We did like that the app still had all of the features of the Pro 5000 — like the progress badges and brushing personalization.
Our final metric was a battery test, which accounts for one-tenth of the total score. We ran each brush for four minutes a day, two in the morning and two at night, and scored each one on how long it lasted. The Pro 8000 had a slightly below average battery life, earning it a 4 out of 10 for the 18 days it lasted.This model had a typical battery indicator, similar to the Pro 5000. It consists of a battery silhouette with three bars inside to signify the charge level. This model also has a flashing red light to indicate when the battery is critically low, which we noticed corresponded to a drop in brushing power.
This model is a little on the pricey side, making it a poor value option. There are much less expensive models that easily outperformed it.
The Pro 8000 tied for the best cleaning performance of the group and was very easy to use, though we were disappointed with how difficult the position sensing was to use properly. This model can even be too much cleaning power for those with sensitive gums and can be a little awkward to brush with for those with more petite mouths, but all in all, it's a decent toothbrush, though there are plenty of better brushes that have fewer extraneous features and cost a whole lot less that will serve you just as well.
