You will notice a big difference from normal toothbrush, just replace when the blue fades to white
on 6 April 2018
When you have a good toothbrush its really good to renew the heads regularly. They do have a blue edge that starts to fade when you need to renew but somtimes I think you know when they go out of shape that you need to change. These come with the little coloured rings so that you know whos brush is whos.
Update- The whole family have been using these for a couple of years and we all have better teeth and stain free. No more scale and polish at the dentist because it is easy to be thorough with these heads. They are great!
