Philips DiamondClean 9000 - the intelligent one
4.3Overall Score
Name: Philips DiamondClean 9000 Model HX9912/17
Price (RRP): $379
Manufacturer: Philips

I don’t recall needing a university degree in toothbrush operation. The Philips DiamondClean 9000 may well be one that I need to read the manual.

All jokes aside the Philips DiamondClean 9000 and the Philips Sonicare app offers a suite of tooth care indicators. All you need is to set up an account and share your data with Philips.

What is it?

In its most basic form, it is a rechargeable electric toothbrush, and you can use it just that way.

But that is just the beginning as you use the Philips Sonicare app to track your toothbrush use.

If you look carefully there is a Wireless symbol at the base of the brush.

These have a micro-chip to identify the brush to the handle, and it automatically selects the right program. Cleaning can take from two to just over three minutes.

It also comes with a glass charge cup and charge base as well as a travel case with USB-A charging.

How do you review a toothbrush?

I mean, isn’t it obvious? Put toothpaste on the brush, insert into the mouth and wiggle it around. Do it for at least a week and draw comparisons with your daily toothbrush.

I wish.

This is a product that will give results over time, perhaps not that evident after a week of use. Sure, it is an effective cleaner with the C3 brush. And it tells me that I am pressing too hard as well as any areas I may be missing. Philips claims up to 10x plaque removal, and it will start whitening teeth (W3 brush).

Next week I will alternate with the W3 and see if that makes a difference. I think the ability to use up to four different brushes is an advantage.

Overall Philips is banking on you not baulking at the $379 price and talking its word (and I guess ours) that it will be better than most electric toothbrushes.

Is it?

I think so but my daily brush (for most of the past two decades) is the Oral B Pro Series that has a little warning light if you are pressing too hard. It uses little round and expensive ($6-10) toothbrushes (about the same price as Philips). Its retail is $159, but you can get them for $87 at Shaver Shop. They last about five years before the battery gives up. To be fair Oral B has smart models up to $500.

And to be extra fair Philips has lower-cost models too (comparison here). It is banking on reviews like this to pique interest in the brand.

It has an Easy-Start program that will gradually increase the intensity over 14 cleans if you are not used to electric toothbrushes. I did not need that.
