How long does an electric toothbrush last?

Once you buy an electric toothbrush, you may wonder how long you can use it.

This blog explains how long an electric toothbrush lasts and how to make it last as long as possible.

Electric toothbrush lifetime

To begin with, the lifespan of an electric toothbrush depends on the model, how often used and how stored.

It is therefore difficult to say for sure how long an electric toothbrush will last, but it is advisable to assume that the battery life of an electric toothbrush is "about 3-4 years".

For example, the KIWIBIRD electric toothbrushes have a battery (lithium-ion battery) life of approximately 4-5 years.

If you use an electric toothbrush other than a KIWIBIRD for 3 years, the lithium-ion battery will deteriorate and is likely to reach the end of its lifespan.

When the battery of an electric toothbrush reaches the end of its life, even if it is fully charged, the time it can be used is extremely short and you will not be able to brush your teeth satisfactorily.

The recommended time of use for an electric toothbrush is 2 to 3 minutes, which is a very short period of time.The electric toothbrush will probably work fine when fully charged, even if the battery has deteriorated, if you use it for 2 to 3 minutes.

For almost five years now, my Kiwibird black electric toothbrush has been working perfectly.

As a general guideline, we only consider a life expectancy of "approximately 3-4 years".

How to extend the lifespan of your electric toothbrush

When hearing that the lifespan of an electric toothbrush is about 3 to 4 years, some people may think it is shorter than they think.

Proper use of electric toothbrushes helps to extend the lifespan

Here are some tips on how to extend the lifespan of your electric toothbrush.

Proper storage and charging

It is important to store and charge your electric toothbrush in the correct environment to prolong its lifespan.

Many electric toothbrushes are waterproof to a certain degree, and there are high-performance models that are described as "fully waterproof".

But "waterproof" is not the same as "moisture-proof".

Even if the KIWIBIRD white electric toothbrush is highly waterproof ipx8, you should avoid storing and charging it in a damp place (such as a changing room near a bathroom).

Regardless of the water resistance of an electric toothbrush, storing and charging it in a damp place can shorten the life of the electric toothbrush itself.

Electric toothbrushes should also be kept cool and out of direct sunlight.

Do not leave the electric toothbrush unattended when the battery is flat.

Never leave the electric toothbrush uncharged.

The batteries of electric toothbrushes (lithium-ion batteries) are likely to deteriorate as a result of discharge and their life will be shortened if they are not recharged.

If you forget to charge the battery for a few days, it will not deteriorate as much, but if you leave it for a long time, the battery will deteriorate considerably.

If you have bought a spare electric toothbrush that has been unopened for a long time, open it immediately. Make sure it is fully charged every six months.

How Do I Know When to Replace My Electric Toothbrush?

An electric toothbrush that has reached the end of its useful life has the following characteristics.

• Very short life, even after recharging
• Smells burnt
• Turns on and off when the power cord is moved

If the electric toothbrush is in the condition described above, it is recommended that you stop using it.

If you continue to use an electric toothbrush that has reached the end of its useful life, it may become "simply unusable" and other conditions may worsen.

Because electric toothbrushes are used almost every day, it is easy to notice the difference.

If you find your power toothbrush uncomfortable

• Is the electric toothbrush used for a very short time?
• Is there an unusual smell, such as a burning smell?
• Is it rechargeable?

Let's try to distinguish it from these.

If you have any questions, it is best to contact the after-sales service listed in the instruction manual.

Do electric toothbrushes lose power over time?

Yes, electric toothbrushes can lose power as their batteries need to be replaced over time.

Most electric toothbrushes are rechargeable, so this is not a one-off purchase.

However, it is still important to monitor the battery life of your electric toothbrush because if it no longer provides enough power for effective cleaning, you may need to replace it.

Just like the KIWIBRID Pink electric toothbrush, a single charge provides at least 300 days of minimal oral cleaning, 

Is It Okay to Use an Electric Toothbrush Every Day?

Do electric toothbrushes work better

Yes, it's perfectly fine to use an electric toothbrush every day!

They are designed for regular use and can actually be more effective at removing plaque and promoting good oral health than manual toothbrushes. 

Also, the KIWIBIRD green electric toothbrush usually have replaceable heads, so they do not contribute to environmental pollution.

By using an electric toothbrush every day, you can monitor your progress and make sure you're brushing correctly. 

Most electric toothbrushes come with a timer to help you brush twice a day for two minutes each time, as recommended by experts.

Overall, electric toothbrushes are an effective way to improve dental hygiene and promote good oral health.
