The great benefit of app-connected brushes is the feedback they provide. While you might not end up using the app every day for the rest of your life, if you need to overhaul your brushing technique, it’s an excellent short-term tool.

A lot of its positive effect on dental health comes from the increased awareness of brushing technique. When it comes to a daily task like brushing, it’s easy to do it on autopilot and fall into bad habits such as neglecting certain areas of your mouth, not brushing for long enough or pressing too hard on your gums or teeth.

Many of us will have missed a dentist’s visit or two over the last few months, so spending some time focusing on dental care is no bad thing.

The app-connected 6500 will give you brushing guidance in real time, while the brush itself has five cleaning modes, including gum care, whitening and a sensitive setting. It also has a pressure sensor that lights up red when you’re pressing too hard and a timer to let you know when you’ve brushed for long enough.

Oral-B app

In the box, you’ll also get three replacement cross-action heads, a smart timer and a travel case.
