How often do we need to replace the heads of the electric toothbrush?

25 May 2017

One of the most frequent questions regarding the heads of the electric toothbrushes is their longevity. The answer’s rather simple though, as pretty much every manufacturer recommends replacing the head tip every 3 months. In other words, the head tips need to be replaced just a soften as the regular toothbrush.

The tip of a toothbrush consists of hundreds of bristles, the combination of which forms the head. Some of the bristles are shorter, others can be longer, positioned under different angles or colored in different colors. The nylon structure is very durable and can withstand thousands of repeated movements, until the time when the bristles lose their properties comes. It’s just like with car tires. After some time, replacing them is necessary, even if the signs of wearing out aren’t visible to the naked eye yet.

When should we replace the tip?

After 3 months of usage, most of the head tips start showing the first signs of wearing out. It’s important to take a closer look at the bristles, check if it’s even and keeps facing the same direction. Comparing the old head tip to the brand new one is a good idea. If the bristles are shorter, ragged or stick out, it’s time to buy a new head tip. A frequent case of the bristles wearing out faster than they should is pushing them against the teeth too hard.

Damaged, burned or spread bristles ensures low quality of brushing and might have negative effects on teeth and gums. Marking the day we bought the new head tip on in our calendar and/or planned day we should replace it is a good idea.

Bristle state indicator

Monitoring the state of our bristles is made easier by the special indicators which can be found, for example, in the head tips made by Philips Sonicare and Oral-B. At first, some of the bristles are darker, but as the time goes on, the bristles become brighter in color. A washed out color means that it’s time to replace our head tip.
