Sonicare Toothbrush Lifespan: How Long Does It Last?

Are you thinking of switching to an electric toothbrush from a manual one? Or maybe you are simply wondering about upgrading your old electric toothbrush to a new Sonicare toothbrush? Whatever the reason, we are sure that one of your main concerns will center around the lifespan of your future toothbrush.

Let’s face it, electric toothbrushes are pretty expensive, especially in comparison to the old manual ones. So if you’re going to invest in one, you need to make sure that it’s worth it. In this article we will take you through the length of time the battery lasts, the average lifespan of the Sonicare toothbrush, and tips on how to improve the lifespan.

First up though, we’ll quickly go through some of the main advantages of using an electric toothbrush compared to a manual one. If you’ve already got an electric toothbrush and are just looking for an upgrade, then you can skip down to the next section instead.

What are the benefits of a electric brush?

Benefits summarized:

  • Effective bristle design
  • Helps to not brush too hard
  • Inbuilt timer

Cleaning your teeth is such a frequent event (we hope) that you probably do it on auto-pilot, without really thinking about it at all. However, lots of people actually have really bad teeth-cleaning habits, which can cause quite a lot of harm to their teeth. It might sound obvious, but each tooth needs to be cleaned on each side.

This prevents the build-up of plaque or the formation of tartar, which in turn prevents infections, tooth decay and gum disease. An electric toothbrush has the bristles pointing in carefully designed directions, to make sure that they get the maximum reach on your teeth. By spinning around quickly, they are able to cover a lot of different angles, which you are unlikely to achieve by simply moving with your hand.

A lot of people have a problem with brushing their teeth too hard. This can wear away the enamel, cause sensitive teeth, and even lead to the nerves being exposed. In order to prevent this, while still effectively cleaning your teeth, electric toothbrushes are a much better choice. They do the brushing for you, so you can clean with a lighter touch.

Many electric toothbrushes even have different power settings. So if your dentist has warned you about brushing too hard, an electric toothbrush is a great way to improve your dental habits. Finally, most electric toothbrushes have an in-built timer. Usually this will let you know every time 30 seconds has passed, allowing you to brush each quadrant for an adequate amount of time.

It will also have some sort of buzzer and/ or light to let you know when you have been brushing for a full two minutes. That is how long you need to brush for in order to get the full protection from the fluoride in your toothbrush. It’s a really great feature which can make sure that you don’t just get bored after 30 seconds and stop for the day.

How long does the battery last?

Average battery life: 2 – 3 weeks

The other question that a lot of people worry about, particularly when switching from a manual toothbrush to an electric one, is how long the battery will last. It can seem like a strange idea to have to charge your toothbrush, and it can feel like an unnecessary hassle, particularly when we already have so many other gadgets in our lives that need to be charged.

However, toothbrush makers know that this is how people feel, so they’ve made it as easy as possible for us. The average electric toothbrush these days will tend to last for around two weeks. That’s based on two minutes of brushing your teeth, twice a day, every day (of course).

These days, some electric toothbrushes can even stretch to three weeks without charging. In the Sonicare range, that includes Diamond Clean, Flexcare, Flexcare +, Healthywhite +, and the 3 Series brushes.

However, the manuals do tend to state that overcharging shouldn’t affect the battery life of the toothbrush. So if you find it easier, you can just keep it on the charging stand each night. Then you’ll never have to worry about it.

What is the lifespan of a Sonicare Toothbrush?

Lifespan summarized:

  • Average lifespan is 2 – 5 years
  • 2 year warranty
  • Head change needed every 2 months

So, now it’s time for the big question. How long is the Sonicare toothbrush lifespan? Well, Sonicare offers a two year warranty on their toothbrushes. This means that it should last for a minimum of two years, and work well throughout.

Although you will have to change the toothbrush head more often than that (generally at least every couple of months), we are sure you can agree that it is a far longer period of time than any manual toothbrush will last.

Many consumers report that their Sonicare toothbrush can last up to five years. The problem is that the battery will start to fade. As it is built into the brush handle, the battery sadly can’t be replaced, and instead requires a new toothbrush.

However, once the battery has started to go, you can simply keep it on its charging stand each night, and then it should still be usable for a lot longer.

How do you improve the lifespan of an electric toothbrush?

Improve the lifespan:

  • Regular cleaning and maintenance
  • Don’t overcharge

Now we’ll take a quick look at some ways that you can help to improve the lifespan of your electric toothbrush. Some people claim that waiting to charge it until the battery has rundown is the key for maintaining the battery life.

However, the makers themselves say that this shouldn’t be a problem for the electric toothbrushes. No, the best way to improve the lifespan of your electric toothbrush is to keep it clean. How many times have you seen someone’s electric toothbrush, which has been going for a year or two, but it looks filthy? And they use that to clean their mouths.

However, it is really a hotbed for germs and bacteria. Instead, it is important to try to keep your toothbrush clean. We understand that you might not want to clean it twice a day, but at least once a week you should try to get rid of all the grubby toothpaste marks. If not, the germs and bacteria can reduce the effectiveness of the electric toothbrush and reduce its lifespan.


So in summary, the electric toothbrush is a great way to go to improve your oral hygiene, and it has a lot of benefits over the manual toothbrush. If you are worried about the battery life, you can just charge it each night to make sure that it always has battery.

However, it should be able to last for two weeks between charges, so it is still super practical. The warranty of a Sonicare toothbrush means that it should last for at least two years. But if you want the toothbrush to last for longer, keep it clean, keep charging it, and it should be able to last for five years.
