Amazing electric toothbrush

What an amazing toothbrush !! I love the features , from whitening , to max clean and polish. I feel like I’ve been to the dentist after using the polish option. It’s gentle on the gums but effective. I love the instant coverage feedback so you don’t miss any part. The toothbrush flashes a different colour until the area is clean which is really helpful. It also notifies you if you are adding too much pressure. The vibration intensity has 3 levels from low to high which makes it suitable for everyone . Comes with a great charging travel case which I thought was great. I sometimes found it a little difficult to charge in the glass.

It’s a WINNER!

Love this toothbrush! Firstly it feels super premium along with the charger and the carry charging case is brilliant. Battery lasts really long too! I found the guidance such as switching from orange to blue light really helpful and the little screen showing where you have brushed and what’s missing. It also has 3 intensities, and different modes depending on what you want e.g.Sensitive. Overall this is a brilliant toothbrush, it’s definitely on the pricy side which is the only drawback but I can also understand the amount of development that’s gone into it.

For a clean, healthy smile

Philips always get the design of their products right. The diamondclean 9900 is modern and stylish yet chic. It is much lighter than the previous models of sonicare toothbrushes I have owned which makes it easier to use. It has amazing features such as the type of clean you want your teeth to have (clean, whitening or even sensitive), adaptable pressure and a touchscreen monitor. The toothbrush has a light up base which I use to gauge how much pressure I am applying. I have always brushed my teeth using too much pressure and so it is amazing that the toothbrush can help me correct when this is happening. I would however say that these features take a knock on its battery life. My previous toothbrushes would last a long time without needing charge whereas the DiamondClean 9900 needs to be charged weekly. The toothbrush can also be connected to an app but the app does need to be open at the time of using the brush. I did this for around a week and then no longer used it. I would say it is expensive compared to others on the market but I do think oral hygiene is important and so it is worth paying more for knowing my teeth are being cleaned properly.
