Are Electric Toothbrushes Waterproof? (+Tips for Usage)

Electric toothbrushes are all the craze recently – and for good reason! 

After all, dentists love them almost as much as your teeth do. 

If you’re thinking of investing in an electric toothbrush, or already have one, you may find yourself wondering how careful you should be around water. 

Generally, electric toothbrushes are water-resistant. Water can be splashed on them, and many modern toothbrushes can be used in the shower or even submerged in water! 

In this article, we’ll be covering what you can do with your electric toothbrush and what waterproofing standards mean. We’ll also give you some practical tips on how to look after your electric toothbrush. 

Let's get into it!

Waterproofing in Electric Toothbrushes

Electric toothbrushes have become extremely popular in oral care due to their ease of use and great cleaning power.

Studies have found that they clean teeth better than manual toothbrushes –  but just how well do they last? 

Most electric toothbrushes are carefully designed to resist water splashes and sprays that happen when you brush your teeth. 

Popular toothbrushes such as the Boka Electric Toothbrush are waterproof, which means they can resist more water and can even be used in the shower. 

Your toothbrush will have an IP rating, which indicates how waterproof it is. If your toothbrush is water-resistant, it will not be able to be used in heavy water streams such as showers, and should definitely not be submerged.

Tips for Proper Usage and Maintenance

Like most things, you can expand an electric toothbrush’s lifespan by looking after it properly. With the right care, an electric toothbrush can last you up to 5 years. 

Here are the best ways you can look after your electric toothbrush: 

  • Follow manufacturer guidelines on water exposure: Not all electric toothbrushes are built the same. It is best to read the user manual when you first buy a toothbrush, to know what your toothbrush can withstand, in order to avoid water damage
  • Rinse your toothbrush under running water after each use: Rinsing your electric toothbrush head after use helps to remove any leftover toothpaste and food particles from the bristles. Rinsing your toothbrush also makes sure that bacteria do not grow on it between washes
  • Use a soft-bristled toothbrush head: This will help to reduce any damage on the surface of the handle. Plus, softer bristles are better for your enamel!
  • Dry the toothbrush completely with a clean towel before storing it: Giving your toothbrush a quick dry with a clean towel before storing it discourages microbes from growing on your toothbrush. It also helps to avoid any potential water damage from long-term water exposure 
  • Avoid storing the toothbrush in a moist or humid environment: Moist and humid environments can encourage the growth of bacteria and mold. Keeping it away from these environments helps to prevent this, and helps your electric toothbrush last longer
  • Avoid using strong cleaning products: One of the best ways to clean your electric toothbrush is simply with a damp cloth. Using harsh chemicals to clean your toothbrush will likely damage your electric toothbrush and lead to premature wear and tear! 
  • Check the toothbrush for wear and tear: Regularly check the brush head, handle, and charging components for any signs of wear or damage. If you notice any issues, contact the manufacturer for guidance.
