You should change your toothbrush every three months or at the latest when the bristles start to bend outwards. With classic plastic brushes, a lot of waste is created over time. Alternative products made from bamboo, wood or Bio-plastic with an interchangeable head provide a solution. However, electric toothbrushes provide the best dental hygiene. One Study from Great Britain However, in 2020, electric toothbrushes were found to have a worse ecological balance than conventional manual toothbrushes. This is a dilemma for people who rely on sustainable products in their daily tooth brushing routine. Fortunately, a lot has happened in the market since the study was published.

What are the advantages of an electric toothbrush?

There is no more convenient way to clean your teeth than with an e-tooth brush. And not a more hygienic one either. Small rotating brush heads reach even tiny gaps in the tooth surface and between the teeth. They also protect the gums, which reduces injuries. Electronic sonic toothbrushes represent a further development: Instead of an electric motor, they work with sound energy in the high frequency range. With 30.000 movements per minute, they work ten times faster than an electric toothbrush and a hundred times faster than a manual toothbrush. The gums react to the changing pressure changes of the sound and are supplied more intensively thanks to cell activation. In addition, the toothpaste foam also reaches hard-to-reach places in the mouth - the result is less bacteria, plaque and gum inflammation.

The benefits of an electric toothbrush

  • Easy to use
  • Better cleaning performance
  • High comfort
  • Gentle cleaning method
  • Less plastic waste

What to look for when buying an electronic toothbrush

• Recyclable brush heads: If you are environmentally conscious when it comes to oral hygiene, you should use toothbrushes made from recyclable or biodegradable materials. This also applies to brush heads. In addition to those made from plastic, some manufacturers now also offer replaceable heads made from bamboo.

• Quality battery: The battery is the heart of every electric toothbrush and determines its lifespan. When buying, make sure that the toothbrush has a lithium-ion battery (Li-Ion). They are more robust and durable than nickel-metal batteries (Ni-Mh). For comparison: While weak batteries run out after just 100 minutes, lithium-ion batteries only need to be charged after more than 300 minutes.

• Proper disposal: If an electric toothbrush has served its purpose, it can be taken to a recycling center. Since 2016, shops, online and mail order companies that sell electric toothbrushes have also been obliged to take back used products. An alternative is the Terracyclye Recycling program.
