How to Charge an Electric Toothbrush?

Brushing your teeth is the key to maintaining good oral hygiene. In reference to the American Dental Association, using electric and manual toothbrushes work well in preventing diseases and tooth decay.

Would you love to upgrade from using a manual toothbrush to an electric toothbrush? Using an electric toothbrush provides you with an array of benefits.

The brush does all the work for you, and it is superior in removing plaques as compared to a manual toothbrush. Other benefits of using electric toothbrushes include:

  • They have built-in timers
  • Good for kids
  • The brushes are safe for the gums
  • Perfect for people with orthodontic appliances
  • Boost your focus when you are brushing
  • Lead to less waste
  • You need to charge your electric toothbrush and depending on the model that you have; it should take around 14-22 hours to charge the brush fully. It should take you between 5-12 days when you are brushing twice a day for two minutes each time.

The big question that many people ask, how do you charge an electric toothbrush? How do electric toothbrushes charge through plastic?

The type of charging that occurs is called induction. This is where electrical currents produce a magnetic field.

The moving magnetic field will create current in the coil wire of the toothbrush. The flow from the electric toothbrush coil wire will charge the battery.

How It Works

The primary and whole concept about an electric toothbrush is electricity. Without power, the toothbrush cannot work as expected.

Though you can brush your teeth manually with it, it will not do it for you automatically but using your force. When it has power, you only direct it through your mouth, and it does the rest of the brushing for you.


An electric toothbrush uses batteries that are charged and they store power for your daily use. You won’t be able to use an electric toothbrush with ease if your batteries are dead or when it is not charged.

There are two ways to keep the power on the toothbrush on and ensure ease of use. You can either keep the toothbrush plugged in its charger or change the batteries when you notice they are dead or if they are losing power.

It is an excellent way to help ensure that you use the toothbrush anytime you feel like and effectively.

However, running out of power does not mean that you discard the toothbrush since it is still useful.

A way out to keep using it is that you can either continue brushing manually using your hands to apply force to the toothbrush or you can get a regular toothbrush if you can access one to brush your teeth with.

Electric toothbrushes come in various types and designs which make their performance vary. Some have heads that can vibrate for up to 8,000 strokes per minute while others can go up to 40,000 strokes per minute.

It extends the reach of the toothbrush to get through the tiniest of spaces and get rid of plaque. The more the strokes a toothbrush has, the more the power it uses.


An electric toothbrush does not have a metallic part to avoid it ever from coming into contact with water especially when it is charging or plugged in. Contact with water could result in an electric shock, and this would not be safe or comfortable for you.

If it is not plugged in and the metal surface still comes in to contact with water for long, it would result to the toothbrush not working correctly. In place of a metallic part, there is a plastic coating to ensure safety.


Insert the charger into the socket but do not switch it on. Make sure the toothbrush doesn’t have any water or toothpaste on it before placing it on the charger.

Some have holders to make charging easier. After setting the toothbrush firmly, switch on the socket and leave it to charge.

Most of the toothbrush companies have designed them to have indicators which help you to know when the toothbrush is fully charged and ready for use.

It is advisable to let the toothbrush charge continuously until it is fully charged and not use it in between charging.

 Using the toothbrush as it charges and placing it back may cause the batteries to get worn out quickly which results in less brushing time before recharging it again.

Also, make sure that the toothbrush is charging on a dry surface and that it is out of reach of kids who may tamper with it.

The toothbrush charges through the plastic material through a method called induction. This method is where an electric current produces a magnetic field that causes the current to flow in different directions.

Testing of the magnetic field has been done where a needle places near the wire as it charges turns like that of a compass.

A current flowing in the opposite direction is the reason as to why it directs the flow of the magnetic field.

An electric toothbrush includes a wire that has been coiled inside it to conduct the electrical current needed to power the toothbrush. This wire is essential since it does the current from the socket or charger where the toothbrush has been plugged.

The magnetic field created from the charger to the coil changes direction as the magnetic field created changes direction as well. This, in turn, produces the power needed to get the electric toothbrush working.

The energy is stored in the batteries where after they are full, you can unplug the toothbrush and turn it on to enjoy an easy and fast brushing experience.

The battery is charged by the continually moving magnetic field which creates a current. The current, in turn, generates power which is stored in the batteries.

The batteries can last a couple of days before being recharged again depending on how frequently you use the toothbrush to brush your teeth.

A good battery should have a long life and a high power retention period. Some toothbrushes are designed to have replaceable batteries while others have rechargeable ones.

For those with replaceable batteries, they do not need any power since once the cells are dead, you just buy new ones. The better ones are those with rechargeable batteries since it saves on cost and efficiency.

You only need to plug your toothbrush and charge it for efficient brushing.

A good rechargeable battery should stay for at least 3-5 years before being replaced with a new pair. Another way to range your battery’s ability to store power is the frequency of charging between uses.

A good battery should at least serve you for two weeks before charging it again. When this duration between charges decreases then it is time to change the batteries and get a new pair.

Final Words

An electronic toothbrush has soft bristles that help remove plaque and particles that are stuck in the tiniest of spaces between the teeth. It helps clean your teeth thoroughly.

 Choose one that best suits your brushing needs and enjoy oral hygiene every day. Always charge your toothbrush with the right charging appliance and don’t allow it to stay too long when the batteries run out of charge before recharging them.

It will ensure your toothbrush serves you efficiently and you will not regret having an electric toothbrush.
