Key Differences between Sonicare Diamondclean 9000 vs ExpertClean 7900

At the outset let me mention that the differences we explore below are subtle and may not necessarily be deal breakers if you are torn on which model to choose between the two.

  • One of the key differences between these two is in the type of brush heads that each model comes in. The Philips Sonicare ExpertClean 7900 is marketed as a purely whitening toothbrush and that is why you get four W2 Optimal White brush heads. This contrasts with the Diamondclean 9000 which has one brush head, and the C3 Premium plaque defense in its package.   
  • In the UK, the Diamondclean is mainly sold in pairs (you get two brush heads and two C3 brush heads) which is appealing when buying for couples or families.  The expertclean 7900 comes only with one handle but with four whitening brush heads.
  • The DiamondClean 9000 features a high-quality travel casing with a USB cable designed into it, whereas the charging cable on the ExpertClean travel-case is detachable.
  • As compared to the tough plastic shell case of the ExpertClean, the 9000’s travel case has a lid that’s coated in a gentle touch leather while the Sonicare name is inscribed in gold font which gives it a more premium feel and look when compared to the 7900 that has the white Sonicare text designed and printed onto the tough plastic ExpertClean case.
  • Additionally, the 9000‘s case has a USB cable designed into it. Permanently wired in the foundation of the casing, there’s a place to store the cable when not used. It’s seen via a removable cover. With the ExpertClean case, however, the USB cable is removable. 
  • On one end of the casing is a micro USB port into which the cable could be hooked up. This actually leaves the possibility for the cable to be mislaid or even lost as it’s a distinct product to take when traveling. 
  • Inside the case, there’s a slight variation too, as a result of the way the two brushes are recharged. The ExpertClean case features a prong that fits in the foundation of the ExpertClean, whereas the DiamondClean casing doesn’t.
  • The ExpertClean can be purchased in white, pink and black colour choices when compared with the pink and black colour options of the DiamondClean 9000. However, both brushes are made in two colour options (black and whte). 
  • The ExpertClean has a conventional charging stand when compared with the more premium version in the DiamondClean often describes as a’ charging glass’,
  • The ExpertClean charging stand is lighter and uses up less countertop space than the 9000. Both charge wirelessly, though the design differs.

Both the Philips Sonicare Series 7900 Advanced Whitening Sonic Electric Toothbrush with app (Model HX9631/17) and Philips Sonicare DiamondClean 9000 Black Electric Toothbrush, 2020 Edition, 4 Modes, 3 Intensities, Gum Pressure Sensor, App, Connected Handle, UK 2-Pin Bathroom Plug, Packaging May Vary have 4 brushing modes (clean, white+ gum health and deep clean) and three cleaning intensities, but is provided with an individual brush head.

It is also true that all Sonicare toothbrushes make use of a sweeping motion (unlike the oscillating activity of several other brushes) and go as much as 62,000 times a minute. These high frequency movements carefully get water to sweep between your teeth to remove foods and plaque with no hard brush which can potentially harm the gums.

The differences between these two designs are subtle and have no significant bearing on daily use.

The DiamondClean 9000 has little subtle, high end visual differences. However the Expertclean can do what the Diamondclean can if you invest in buying the C3 premium brush head because it is primed  to focus on whitening teeth. The C3 alongside the defence.
