What is the Oral-B Smart Series 4000N electric toothbrush?

The Oral-B Smart Series 4000N is a rechargeable electric toothbrush which can remove up to 100% more plaque than a manual toothbrush. It uses a round brush head to clean each tooth individually and can give you healthier gums in just 30 days when compared with a manual toothbrush. This electric toothbrush includes a range of features which make cleaning your teeth more effective than ever, including different brushing modes, Oral-B app compatibility, a 2-minute brushing timer, and pressure control.


How will this toothbrush give my teeth a superior clean?

The Oral-B Smart Series 4000N has 3 different brushing modes, so you can choose the clean that’s right for your teeth, including Sensitive, Daily Clean, and Whitening modes. The 2-minute timer helps you to be sure that you’ve brushed your teeth for the recommended amount of time, every time, and the pressure sensor keeps you from brushing your teeth and gums too hard, protecting your gums.


Why is it so important to keep my teeth clean?

It’s important to clean your teeth twice a day for 2 minutes at a time, as this helps to remove the build-up of plaque, bacteria, and debris that builds up on your teeth throughout the day. If given the right conditions, plaque acids and bacteria can damage your teeth and gums, causing tooth decay and gum disease. A thorough and regular dental care routine that includes brushing, flossing, and rinsing can help to keep your teeth healthy and looking clean.


How can I use the Oral-B app with this toothbrush?

The Oral-B 4000N toothbrush connects with the Oral-B app via Bluetooth, which unlocks a range of features which can help you to improve your brushing habits. The app can use position detection to see how long you brush each zone of your mouth, advising you to focus on any areas you don’t always brush as well as you should. People who switch to an Oral-B Smart Series toothbrush and use the app can see up to a 73% reduction in plaque after just 2 weeks.

How long does this toothbrush last when it’s charged?

  • Oral-B Cross Action
  • Oral-B 3D White
  • Oral-B Sensi Ultrathin

  • Oral-B Floss Action

How often should I change my electric toothbrush head?

Dentists advise that you should change your electric toothbrush head or manual toothbrush every 3 months to be sure that you’re getting the most out of your clean. Over 3 months your brush goes through natural wear and tear which wears down the bristles and makes them less effective. This makes it more difficult for you to clean your teeth effectively and is why you should change your toothbrush regularly.
