Different Levels Of IPX Ratings And What They Mean

You need to consider many factors while choosing an electric toothbrush. One important consideration is the IPX rating, which indicates the level of protection the toothbrush has against water.

Understanding the different levels of IPX ratings can help you make an informed decision when purchasing a waterproof electric toothbrush. Here are the various IPX ratings and what they mean for electric toothbrushes:

IPX0: This rating indicates that the product provides no additional water protection. It is not recommended for use in wet environments.

IPX1: With an IPX1 rating, the product is able to withstand water droplets that fall vertically on it. However, it is not designed to handle any other water exposure.

IPX2: Products with an IPX2 rating can handle water that hits them at an angle of 15 degrees or less. This means they can withstand light splashes or accidental spills.

IPX3: An IPX3 rating indicates that the product is capable of withstanding water sprays up to 60 degrees. This makes it suitable for use in bathrooms where water splashes are common.

IPX4: Products with an IPX4 rating can handle water splashes from any direction. They are suitable for use in wet environments such as showers or near sinks.

IPX5: With an IPX5 rating, the product can withstand extended exposure to low-pressure water jets. This makes it suitable for use in environments where water jets, such as certain dental settings, may be present.

IPX6: Products with an IPX6 rating are able to withstand powerful and high-pressure water jets. This level of protection makes them suitable for use in environments with strong water jets.

IPX6K: The IPX6K rating indicates that the product can withstand exceptionally high-pressure water jets. However, this rating is rarely used and may not be relevant for most electric toothbrushes.

IPX7: A product with an IPX7 rating is suitable for submersion in water up to 1 meter deep for a duration of 30 minutes. This level of protection ensures that the electric toothbrush remains functional even if it is accidentally dropped in water.

IPX8: An IPX8 rating means that the product can withstand submersion in water up to one meter deep. Manufacturers usually provide precise depth information to help consumers understand the limits of submersion.

IPX9K: The IPX9K rating is designed to withstand close-range, high-temperature, high-pressure sprays. This level of protection is rare and not commonly used for electric toothbrushes.

Waterproof Vs. Water-Resistant

We must understand the difference between waterproof and water-resistant to protect items from water damage. These terms are often used interchangeably. But they actually have distinct meanings. Here are the definitions of waterproof and water-resistant and their differences:

Understanding Waterproof

Waterproof refers to a material or product that is impervious to water. It means that no water can penetrate the surface, ensuring complete protection against moisture. A waterproof item will keep your belongings safe and dry, whether it’s heavy rain, water splashes, or accidental submersion.

Waterproof materials are designed to create a barrier that prevents water molecules from passing through. This is achieved through techniques such as special coatings, laminating multiple layers, or tight seals and closures.

Understanding Water-Resistant

On the other hand, water-resistant refers to a material or product that can somewhat resist water penetration. But it may not provide complete protection. It is designed to withstand exposure to water for a limited time or in specific conditions without allowing water to seep through immediately.

Water-resistant materials have some water repellency, usually achieved through treatments or coatings that help beat water on the surface. While water-resistant products can withstand light rain, splashes, or brief exposure to water, they cannot withstand prolonged contact or submersion.

Are Electric Toothbrushes Waterproof?

Electric toothbrushes have different water protection levels, depending on their design and features. Based on the aforementioned criteria, electric toothbrushes are water-resistant rather than completely waterproof.

Some electric toothbrush models may say they are waterproof, but water can still get inside them and cause problems. That’s why the manufacturers usually recommend not to soak these toothbrushes in water for a long time.

So, your electric toothbrush can handle a bit of water. But you should avoid submerging it too long to keep it working well.

Remember, an electric toothbrush can improve your oral hygiene. But you need to use it properly and follow the manufacturer’s instructions to keep it in good shape.

Is An Electric Toothbrush Safe To Use In The Shower?

If your toothbrush runs on batteries, it should be safe. I have personally tested several battery-operated toothbrushes, including some reputable brands, and they worked great.

During my tests, I used them for 10 minutes and 30 minutes under the washbasin head, respectively, and they did not shock me or get damaged.

However, fully submerging the toothbrush is not a good idea, as water may seep into the gaps over time. To address this, I experimented with applying hot glue along the gaps, creating a rubber seal on the batteries and button slots. This modification worked well for almost an hour.

Should You Use Your Electric Toothbrush In The Shower?

Using an electric toothbrush in the shower may seem convenient. But it’s essential to be aware of the possible risks.

One major concern is the possibility of water damage. Electric toothbrushes are not designed to function properly when immersed in water. Thus, using them in the shower could cause damage.

In addition, keeping your toothbrush clean can be challenging when used in the shower. Being near your shower and other personal items increases the chances of it getting dirty.

To prevent this, it’s crucial to dry your electric toothbrush after each use thoroughly. Failing to do so may inadvertently expose it to bacteria and germs, compromising your oral hygiene.

Considering these potential drawbacks, I will not recommend you use an electric toothbrush in the shower. I always use a separate, dry area for brushing my teeth to ensure the longevity and cleanliness of my toothbrush.

How To Buy Your Waterproof Electric Toothbrush

A waterproof electric toothbrush is not only convenient but also ensures the longevity of the product. The following are the essential features to keep in mind when buying a waterproof electric toothbrush:

  • IPX Rating

The first feature to consider is the IPX rating. The IPX rating indicates the toothbrush’s waterproof capabilities. Look for toothbrushes with a high IPX rating to ensure protection against water immersion.

Ideally, toothbrushes with an IPX7 or IPX8 rating guarantee waterproof abilities. This means you can confidently use your electric toothbrush even in the shower without worrying about water damage.

  • Brushing Modes

Another important feature to consider is the availability of different brushing modes. Each individual has unique oral health needs, and having a toothbrush that caters to those needs is crucial.

Look for a toothbrush that offers a variety of brushing modes, such as standard, deep clean, sensitive, or gum care. This way, you can choose the mode that suits your specific requirements and achieve optimal oral hygiene.

  • Battery Life

Evaluate the battery life of the electric toothbrush before making a purchase. A longer battery life ensures that your toothbrush will last for a significant period without frequent recharging.

Opt for models with extended battery longevity to avoid the hassle of constantly recharging or replacing batteries. This feature is handy for those who travel frequently.

  • Replacement Brush Heads

Regularly changing your electric toothbrush’s brush heads is essential for maintaining good oral hygiene. Before buying a waterproof electric toothbrush, check the availability and affordability of replacement brush heads.

It’s important to choose a toothbrush that offers easily accessible and reasonably priced replacement heads. This way, you can ensure that you can consistently replace the brush heads to maintain optimal cleanliness and effectiveness.


After reading till now, you know that electric toothbrushes are usually less than 100% waterproof. However, if you are not sure about anything, the following questions will help you clear them up:

Can You Wash An Electric Toothbrush?

To maintain the cleanliness of your electric toothbrush, it is important to rinse it thoroughly with tap water after each use. This will effectively remove any toothpaste residue and dirt that may have accumulated during brushing.

Is It Okay To Leave My Toothbrush In The Water?

To ensure optimal toothbrush hygiene, it is important to air dry your toothbrush properly. Avoid storing it in water or leaving it lying in a pool of water on the side of the sink.

Is It Safe To Store Your Toothbrush In The Shower?

According to the American Dental Association, leaving your toothbrush in the shower is not a good idea. This is due to the moist environment in the shower that promotes the growth of bacteria and germs.


Electric toothbrushes are designed to be water-resistant, with most models having an IPX7 waterproof rating. This means they can withstand exposure to water during daily use without any issues.

However, it’s essential to check the specific waterproof rating of your toothbrush, as some models offer advanced waterproof features. If you properly follow the maintenance and care guidelines, you can ensure the longevity of your electric toothbrush without worrying about water damage.
