Product information

The Oral-B Smart Series 4000 CrossAction electric toothbrush combines cleaning technology with Bluetooth connectivity to the Oral-B smartphone app to give you real-time feedback on your brushing habits that can be adjusted by your dental professional.

The round, dentist-inspired CrossAction toothbrush head oscillates, rotates and pulsates to surround each tooth with bristles angled at 16 degrees while removing up to 100% more plaque than a regular manual toothbrush.

The pressure sensor lights up if you brush too hard to prevent harmful over-brushing and there are 3 modes: daily clean, gum care and sensitive plus a timer to help you brush for a dentist-recommended 2 minutes.

Compatible with the following replacement toothbrush heads: CrossAction, 3D White, Sensitive Clean, Precision Clean, FlossAction, TriZone and Dual Clean.

Content: 1 handle with a 2 pin UK plug, 2 brush heads
Up to 100% more plaque removal: round head cleans better for healthier gums in 30 days vs a manual toothbrush, Protect your gums: pressure control reduces brushing speed and alerts you if you brush too hard, Gently whitens your teeth starting from day 1 by removing surface stains, Know you brush the right amount of time with the 2min professional timer, 3 brushing modes including daily clean, whitening & sensitive, Better brushing results with real-time feedback thanks to Bluetooth connectivity and the Oral-B App, Battery lasts up to 2 weeks with 1 charge with the Lithium-ION battery,

works well but not at full price

I received this product for free to review. This toothbrush works very well and I like the added feature of the buzz every 30 seconds so you know how long you've been brushing your teeth. I wouldn't pay full price but at the half price offer (£60) I think this would be a decent price. The only downside (and it is common to all electric toothbrushes I have used) is it takes ages to charge.

excellent but expensive

Excellent product, but wouldn't pay £120 for it. Brush heads get into awkward areas leaves your mouth clean and feeling fresh.

Amazing purchase

This is a great toothbrush- it has 3 different settings and you can really feel how clean your teeth are after brushing. The timer is really helpful as it vibrates every half minute to remind you how log you have been brushing. It is easily rechargeable.

Yes, this is an expensive toothbrush but, honestly, it's worth every penny; and even more so if you find it on offer! I have very sensitive teeth due to receding gums and this toothbrush has been a godsend for me. If you like tech, you'll love the accompanying app. A super buy and very highly recommended.

Excellent Toothbrush

The sensitive setting is ideal for my sensitive teeth leaving them incredibly clean. Being able sync my smartphone to the oral b app its taught me how to brush my teeth correctly for the correct length of time and the brush will even tell me if I brushing too hard. Great purchase
