How Long Do Electric Toothbrushes Last?

When you compare an electric toothbrush to a conventional one, the results speak for themselves.  It might take a few days to get used to the “tickle” or control the pressure you put on your teeth and gums.  Once you settle into your routine, the health and efficiency benefits of an electric brush make all the difference.

But let’s face it: An electric brush costs a few bucks more than the model used in Ancient Egypt. So even though an electric toothbrush delivers a host of advantages, you might wonder “How long do electric toothbrushes last?”

There are a number of factors that have to be considered when it comes to buying and owning an electric toothbrush. Since they’re electric, they eventually go the way of all electric devices. After all, they eventually must run out of power, right?

To extend their life, all electric toothbrushes come with interchangeable bristle heads.  The bristles wear out with repeated use before the power dies for the last time. When this happens, you simply change the brush head. You can extend the lifespan of a quality electric toothbrush for many years, and you only have to change out the brush.  Talk about getting the best of all worlds.

When you consider, “How long do electric toothbrushes last,” there are two parts to the answer. The brush head and the electric body offer different life expectancies, and you’ll get maximum life out of your brush with proper care.

When Do You Need to Change the Brush Heads?

Most experts agree that you can use your electric toothbrush regularly and the bristle head should deliver exceptional plaque removal for three months. Of course, there are a few factors that determine an accurate lifespan.

For example, are you currently able to simply remove the brush attachment and install a new one?  Or does your model consist of one component that’s headed to the trash after a few months? This is a key metric that affects how long electric toothbrushes last.  It could mean the difference between three months and three years.

If you own a more expensive electric toothbrush with a detachable bristle head, you can keep the brush for as long as it manages to function properly. This ability enables you to get years of brushing out of one device. In fact, many people have used their electric toothbrushes for more than 10 years simply by switching out the brush head!

When it comes to switching the bristle head, the best practice is to follow one of the universal rules from dental professionals:  Replace it every three months. This simple guideline ensures that your oral power tool functions at the highest level.

If you’re unable to replace the head, or the body just needs to go, you should consider replacing the entire toothbrush. For instance, you might find it impossible or difficult to get the head replaced. You might also have tough times finding a replacement.  Depending on the brand, it’s quite common to run into this dilemma.

Bottom line: No matter how you go about it, ensure that the bristle head is changed regularly. Since you’re going to take the time to brush your teeth, make sure the bacteria don’t stand a chance.

When Do You Need to Change the Batteries or Recharge?

As we mentioned above, there are two types of electric brushes. They feature essentially different mechanisms, which affects how long an electric toothbrush lasts.

Let’s break it down.

Battery-Operated Electric Toothbrushes

This type is the one that you need to change as soon as their batteries begin to die. Of course, that would seriously depend on the overall usage.

If you are using them at least twice a day, the batteries will die in half the time of a conscientious twice-daily brusher. Of course, different people have different habits. Some floss and use water flossers, and brush a bit less. As a general rule, if you’re using the brush twice a day for a couple of minutes, expect to change batteries about once a month.

Rechargeable Electric Toothbrushes

These don’t have throw-away batteries. They’re very convenient and are usually considered a superior alternative to battery-operated models. You’ll enjoy convenient recharging with a plug-in charger, much like the one you have for your phone.

The best practice is to recharge your brush every week or so. Alternatively, you can put it on its station and keep it plugged in at all times when you aren’t using it.

However, you might not have a power socket where you brush your teeth, such as when you’re traveling. In any case, these are particularly convenient and characterize most of the quality models on the market.

When it comes down to it, the interval to change the bristle head or the batteries on an electric toothbrush depends on a few factors. However, the guidelines above should provide you with a fairly relevant estimation. This is going to ensure that everything is handled at the highest standards and you maximize the value of your brush.  Most importantly, good brush maintenance helps keep your teeth clean and healthy.

Final Thoughts

Whether you have to change the bristle head, get new batteries for your brush, or choose a new model, good oral homecare always pays.  A few minutes of prevention or maintenance keeps your dental bills to a minimum.

While there are brushes that don’t allow you to change the heads, you should steer away from them; they’re simply inefficient. It’s better to choose one quality electric toothbrush for a few years and occasionally change the head and batteries than to purchase a new model every few months.

The same guideline rings true for the more advanced rechargeable brands:  Choose a system that comes with interchangeable bristle heads to minimize costs and frustration.  Your mouth and wallet will thank you!
