    Philips Sonicare DiamondClean Review | Several Cleaning Modes For Perfect Teeth

    Last Updated on

    Check out the prices of electric toothbrushes these days, and they can range from $20 to $200. Philips offer toothbrushes that are at the very edge of that range, and some are even more expensive. So is such a toothbrush worth the expense? Let’s find out with this Philips Sonicare DiamondClean review. 

    Toothbrush Review: Philips Sonicare DiamondClean

    For this Philips Sonicare DiamondClean review we focus on the Sonicare DiamondClean HX9371/71. It’s actually affordable compared to the other toothbrushes from Philips, as this isn’t even the most expensive Philips Sonicare DiamondClean out there. You do get your money’s worth with purchase.

    For your money you get the handle, which is nice and thick and comes in a deep blue amethyst color. It has the standard DiamondClean brush head, along with a charger base.

    You also get a glass charger, so you can just put the toothbrush in here to recharge when you’re not using it. It can also be used for rinsing like any other glass you’d use. Finally, you have the premium travel case so you can bring this with you more easily.

    Philips Sonicare DiamondClean Toothbrush: Items Included

    Most likely it’s not as expensive because it only comes with a single brush head. The more expensive options come with more Philips Sonicare DiamondClean brush heads as part of the package. You can always buy more Sonicare DiamondClean toothbrush heads if you wish. 

    Sonicare DiamondClean Toothbrush: Cleaning Modes

    With a manual toothbrush, you need to experiment your way around while brushing your teeth when you have different aims to go for. But with this Philips DiamondClean you can simply just pick the mode that’s right for the situation. Each mode has a different speed and pulse combination

    To pick the mode, you first need to turn the toothbrush on. This will then power the toothbrush in the last mode to use. You’ll know which mode it’s in by the illuminated display on the handle. Just press the power button within 5 seconds to cycle through the modes to get to the mode you want.

    Clean Mode

    This is your everyday cleaning mode, and it’s on the middle intensity level. It uses both the Smartimer and the Quadpacer. The Smartimer sets the timer at 2 minutes, which is the minimum amount of time that dentists recommend for brushing your teeth. The Quadpacer gives you 30 seconds for each quadrant (upper left, upper right, lower left, lower right) so you can focus equally on all your teeth.

    White Mode

    Do you drink a lot of soda and coffee? The problem with these drinks is that while they may keep you awake, you’ll end up more apt to notice that your teeth are getting darker as time passes.

    Fortunately, you have the white mode to take care of that problem. This is specifically designed to remove the stains on the surface of your teeth. It’s particularly geared to brighten and polish the front teeth, as its brightness (or lack thereof) will certainly affect the quality of your smile and your social life.

    The white mode has the same intensity as the clean mode. The difference is that in white mode it pulses much more quickly. Every 2 seconds or so, it alternates between rapid pulsing and steady vibration. About 20 times a second, the intensity is reduced to simulate the rapid pulse effect.

    Like the Clean mode, the whole process lasts 2 minutes with 30-second segments. After that, there are two 15-second segments during which the pulsing slows down at about 4 times a second.

    Sensitive Mode

    Your teeth can feel sensitive when you have cavities, or of you have a hole in the dentin layer of your tooth that leads to the nerves of the tooth. When you have sensitive teeth, you then need to brush your teeth more gently.

    You can achieve this with the Sensitive mode. This gives you the least intense setting to keep your teeth from hurting. Again, you’re given 2 minutes to brush your teeth with 30-second periods. Afterwards, it automatically turns off.

    Gum Care Mode

    This is the most intense setting, and it’s certainly more intense than the regular Clean Mode. You have 2 minutes with 3-second segments to clean your teeth. Then afterwards you can focus on gently massaging your gums, with 4 periods of 15 seconds each for a 1-minute total for your gums.

    Flossing and massaging your gums offer certain benefits, when you have gum issues that result in spaces in gums between the teeth. These spaces are known as periodontal pockets, where plaque, tartar, and bits of food can settle. These pockets can them make it harder to get rid the plaque and food debris. When you massage the gums, your gums become looser so the particles and plaque and then much easier to remove.

    Your gums are also healthier with gum massages. The practice enhances the blood flow to the oral tissues, which lets these tissues to repair itself more effectively. Gingivitis and periodontitis can then become much less likely.

    Deep Clean Mode

    This is also extremely intense, with the same intensity level as the Gum Care mode. However, it offers rapid pulsing, like it does with the White mode although the pulses are much stronger.

    Again, this goes on for 2 minutes divided into 30-second segments, before it turns off.

    Philips Sonicare DiamondClean Rechargeable Electric Toothbrush: Storage and Recharging

    The Sonicare DiamondClean rechargeable toothbrush uses a rechargeable lithium ion battery. A single charge can give you enough power for 2 weeks. If you’re using only Clean mode then you can go for 42 sessions of toothbrushing. If you brush your teeth twice a day, this gives you 3 weeks of use for just a single charge.

    When your toothpaste battery is running low, you’ll see the battery indicator light illuminate. However, all you need to do is to simply put the toothbrush in the charging glass on top of the charging base. Conduction technology does the rest. There’s no complicated charging process, as putting the toothbrush in a glass is something that a lot of people do when they’re done brushing their teeth.

    The glass can even be used to hold water for rinsing your mouth when you’re brushing your teeth. Just take it out of the charging base first.

    You also get a travel case for the toothbrush, and this resembles a nice pencil case. However, the travel case doesn’t really accommodate the charging glass.

    Sonicare DiamondClean Review: How Well Does It Perform?

    The technology on the Sonicare DiamondClean heads provides you with several benefits for your oral health. The first is the sheer mount of brushstrokes done for you. It offers up to 31,000 brush strokes per minute, and that’s well beyond human abilities. In fact, in the 2 minutes you brush your teeth in the morning, your teeth get the same number of toothbrush strokes you’d be able to do on your own in a whole month.

    The brush strokes are gentle as well, and that’s important too. Many dentists recommend that you don’t press too hard on your teeth as this can damage the enamel. The gentle pressure applied by the toothbrush should be safe for your teeth.

    Then you also get the sonic vibrations. These are the pulses that can turn your toothpaste effectively into foam and the pulses can drive the foam deep into the teeth and the gums. If you’re using antibacterial toothpaste, they’d be more effective in eliminating the bacteria in the plaque.

    The results speak for themselves as you get better results than you would with a regular manual toothbrush (and many other electric toothbrushes too). The brushstrokes and the densely packed bristles gently scrub off the stains on your teeth, so your teeth are whiter than you’d expect. In fact, in just 7 days the effects are already noticeable. Your teeth are twice as white as they would be if you were still using a manual toothbrush.

    This is good for your gums too and the results are noticeable in just 2 weeks or so. That’s because the brush strokes, pulses, and dense bristles all work together to get rid of 7 times more plaque than you would with a manual toothbrush. Reducing this much plaque from your gum line considerably reduces the chances of bleeding gums and other types of gum issues.

    DiamondClean Toothbrush: Ease of Use

    It’s natural enough to worry about complicated procedures when you have a gadget with advanced technologies. But part of the high tech design of this toothbrush is that it’s extremely easy to use. Too many Philips Sonicare DiamondClean reviews written by actual customers attest to this fact.

    First of all, recharging isn’t a problem. You just put the toothbrush on the recharging glass. With the amount of time between your twice daily toothbrushing, you’re always at full charge.

    Not that you need a full charge everyday anyway. A single charge is enough for 3 weeks of normal use, and even when you use stronger-intensity modes you can still enjoy 2 weeks of use without having to recharge.

    This is why you don’t really need to bring the recharging glass with you if you’re using this at the office or even for a week-long vacation. A single charge will do the trick.

    Once you get your full charge, you press on the power button and it goes on. It will be in the mode that you last used, and that will be illuminated in your handle display. Press on the button again, and you cycle through the modes until you get to the mode you want to use.

    The handle is solid and substantial, with a nice ergonomic feel to it. It doesn’t feel awkward to use at all If you’re battery needs to be recharged, you’ll notice the warning light for battery power light up, and then you can just place it back into the charging glass.

    You can buy extra Philips Sonicare DiamondClean heads, even though the standard DiamondClean brush head you get is already excellent. You may want to pick other types of tooth brush heads that work well for special modes, like the heads that re designed to work very well for the Gum Care or Sensitive modes.

    Or you can buy other standard DiamondClean heads so that the entire family can use the electric toothbrush. After all, hygiene requires only that you each have a toothbrush head of your own. If you do get a new head for the toothbrush, it’s easy enough to click-on to the handle.

    Durability: How Long Will It Last?

    This is a Philips, and it’s a famous name in electronics. This gadget is designed to be effective, easy to use, and last for a long time. You get a 2-year warranty, and you should get a lot more years than that overall. Generally, you just need to replace the brush heads when the bristles become worn.

    Step-By-Step Process

    To make sure you reap the full benefits of the Sonicare DiamondClean, try to follow these steps:

    1. Start by rinsing the bristles under the tap for a while before you start brushing your teeth. This is to maintain good hygiene. Always rinse the bristles before and then after you brush your teeth.

    2. Put on some bit of toothpaste onto the bristles. An amount the size of a pea will do, unless the toothpaste has different instructions. You don’t want to use too much toothpaste as it can lead to excessive foaming and wasted toothpaste. You also tend to make a mess of things.

    3. Gently press the toothbrush against your teeth. Keep it at a 45-degree angle so the bristles also come into contact with your gums. Focus the middle part of the bristles on the tooth itself.

    4. Now start the toothbrush by pressing the power button. It should start with the mode you last used. If you wish to pick another mode, you can just scroll through the different options to settle on the mode you want.

    5. While the bristles are pressed gently against your teeth, do some small side to side strokes. This allows the bristles clean in between the teeth.

    6. Make sure you use the Quadtimer properly. You should mentally divide your mouth into 4 sections (upper left, upper right, lower left, and lower right) and reserve 30 seconds for each. Make sure you touch upon the front, back, and the top (biting) surface of the teeth, along with the spaces in between the teeth.

    7. Use the extra time you get properly when you choose a special mode. For Gum Care mode, you have an extra minute to use the brush head to gently massage your gums. For the Whiten mode, you have an additional 30 seconds to really buff the surface of the teeth.

    8. The toothbrush will turn off automatically, and you should be done with all your teeth. If not, then just turn it on again to get at the teeth you missed. With enough practice, you should be able to cover each quadrant of your mouth within the 30 seconds allotted.

    9. Rinse the bristles and get rid of any food debris trapped there.

    10. Allow it to dry, and then just place it back in the charging glass.


    As you can see, you do get a lot of value and benefits for every cent you pay when you buy the Sonicare DiamondClean.

    Long Battery Life

    This gives you 2 to 3 weeks of use with just a single charge, and that’s extraordinary. Some of the other well-known brands of electric toothbrushes can only last a single week.


    Philips is basically an electronic gadget maker than expanded their lineup to include electric toothbrushes. This is in contrast with many of their competitors, which are well-known brands in the oral care industry but aren’t exactly famous in the overall electric appliance industry.

    So Philips knows what it’s doing, and their Sonicare DiamondClean is unsurprisingly durable and effective.

    Different Modes

    It’s great that you have different modes to choose from for particular needs. The electric toothbrush will act differently with your changing circumstances. So if you’re having gum issues, you can then go with gum care. You’re noticing a slight darkening of the teeth? Go with Whiten mode. If cold drinks give you sensitive teeth, go with the Sensitive mode.

    Fantastic Results

    How can you argue against having teeth that are twice as bright as the ones cleaned by manual toothbrushes? How can you not want to be able to remove 7 times more plaque? Those are rhetorical questions, since you should want these benefits.

    Easy to Use

    It’s not rocket science, and after a while it’ll be second nature for you to just glide the toothbrush along your teeth to fit in the allotted time. If you’re brushing your teeth regularly twice a day, then it won’t take long to learn how much time to focus on each tooth when you brush your teeth.


    Despite all its fantastic features, the Sonicare DiamondClean isn’t really without its faults. Perhaps Philips can take note of these deficiencies and correct them in the future:


    It seems unfair to mention that this isn’t cheap at all. After all, it’s a premium product with advanced technology, and when the features and durability are taken into account the price is actually reasonable. It’s like the price of a cheap automatic wristwatch, and it’s certainly more useful.

    What’s more you can look at the purchase not as an expense, but as an investment. You pay a significant amount of money now, but you save on paying much more in the future. You save yourself from dental cavities and gum issues that may cost you a lot of money to treat, plus they cause you a lot of unpleasantness.

    Besides, these days it’s easy to find discounts on the HX9371/71. You may find the price reduced by $30 or more.

    You Have to Know How to Use It

    While in many ways it’s very easy to learn how to use this despite the advanced features, you’d be surprised to discover how many people don’t use this properly. This isn’t about the Sonicare DiamondClean in particular, but electric toothbrushes in general. People just don’t know how to use them.

    What you don’t do is to use scrubbing or vigorous motions with your toothbrush. That may be how you use a manual toothbrush, but it’s completely wrong for the electric version.

    Instead, what you should do is just gently glide the toothbrush from one tooth to another, taking care to cover all the sides of the tooth. The toothbrush does all the work, so just let it get to work.

    The Charging Glass May Be Too Large

    This isn’t the prevalent opinion of most users. But quite a few people who live in small apartments and have tiny bathrooms have noted that a smaller glass or a more compact charger would have been nicer. It wouldn’t take up as much space in the bathroom. It can get crowded in there with soaps, shampoos, shaving accessories, and other stuff, and a large glass doesn’t help.

    There’s No Charger with the Travel Case

    As we’ve noted already, the travel case for the electric toothbrush looks like a pencil case. It’s merely for the toothbrush and not for the charging glass. So there’s no easy way to bring the glass with you, and if you just take the travel case you have no charger.

    It is true that a single charge can give you 3 weeks of use, and that should be enough for most vacations and out-of-town trips. It’s also true that you can always bring the charging glass with you. It’s just that this charging glass isn’t especially portable, and a charger for the travel case would have been nice.

    Philips Sonicare DiamondClean vs. Other Brands

    The Philips Sonicare DiamondClean is often listed in the various lists of top electric toothbrushes. So how does it compare with its competition?

    Against the Oral-B Black Pro 1000, it compares very well. This is a very affordable electric toothbrush, and it even has a feature that the Sonicare DiamondClean doesn’t have. It has a sensor that tells you when you’re pressing too hard. On the other hand, it only has a single mode (daily clean) for you to use.

    Against the RotaDent Contour the Sonicare DiamondClean looks even better. The RotaDent has been plagued by recurring complaints about its tendency to stop working properly in just a short time. It sure doesn’t look good compared to the durability and reliability of the Sonicare DiamondClean.


    Are there cheaper brands of electric toothbrushes than the Philips Sonicare DiamondClean? Yes, there are. But they probably won’t be as good. Pick this one as an investment, and you’ll reap healthy teeth and gums as your profit in the future.

    Just be aware that there are many variants of the Sonicare toothbrushes. If you also have braces, then you should pick a specifically designed toothbrush for your braces. But in general, the Philips Sonicare DiamondClean is an exceptionally great choice.
