Why use a bamboo toothbrush?

Bamboo Vs Plastic. Why you should use a bamboo toothbrush.

In today's blog post we’re going to cover why you should make the switch to using a bamboo toothbrush and what to look for when selecting a really great bamboo toothbrush.


60% of us in the UK use manual toothbrushes at an average of four a year. Despite an increase in the popularity of bamboo toothbrushes, the vast majority of the manual brushes we buy are still of the plastic-handled, nylon bristle, variety.


This is bad news for three notable reasons—sourcing, toxicity and disposal.


  • Let's begin with sourcing. Plastic toothbrushes are are no different to the majority of other plastic items; oil-derived. Oil is an increasingly scarce resource that is highly polluting in its extraction, processing and disposal of the waste material.


  • The bad news continues—most users of plastic toothbrushes are unaware of the toxicity hidden inside the product they use on a daily (hopefully twice a day), basis. Many brushes leach toxins such as BPA and phthalates which are linked to health problems including reproductive issues and cancer. More info on this subject on our blog post - what is BPA?


  • The final issue with plastic toothbrushes comes to when its time to replace them. The vast majority of toothbrushes are not recyclable due to the mix of materials used in their manufacture, and the contaminated plastic in the bristles. As a result, most toothbrushes will end up in a landfill or worse, our seas, where over time they break up turning into microplastics (which we will be covering in a future blog post) —tiny but very harmful pieces of plastic that can kill marine life and even make their way into our food chain and drinking water.




Suddenly an innocuous, everyday item like a plastic toothbrush doesn't seem so innocent as we think about the repercussions of using them instead of a sustainably-sourced, biodegradable, toxin-free, environmentally less hazardous, alternative. 


So what's the answer? Drumroll please for the bamboo toothbrush. This unsung hero could be doing more for the environment than you think.


Bamboo is the fastest growing plant on earth (up to 3 metres a day for some species). This is an important characteristic as it makes bamboo a highly renewable and super sustainable crop, meaning a small patch of ground can repeatedly be harvested producing enormous amounts of raw materials.


Bamboo can also be cultivated without the use of pesticides or fertilisers which often contain highly toxic chemicals, and to top it off bamboo produces more oxygen and absorbs more carbon dioxide than any other plant.


Sounds like a great alternative to toxic and non-renewable, oil-based plastics!


What about disposal?


Bamboo is biodegradable and can be safely returned to the soil via your compost heap or your local authority's green waste without fear of leaching toxic chemicals into the environment (provided there’s no toxic paint on the handles).


This leaves only one thing, the elephant in the room, the bristles.


Traditionally toothbrush bristles are made from Nylon which is durable and flexible and provides a good source of abrasion, making it an ideal candidate for brushing your teeth, but it's not so great for the environment.


The manufacturing process for Nylon is a substantial source of greenhouse gas emissions and the single most significant source of plastic-pollution in our oceans.


Many companies that produce bamboo toothbrushes will neglect to tell you their bristles are  Nylon, which can add complexity to their disposal and undermine the efforts of customers trying to live plastic-free.


A common biodegradable alternative is the traditional hogs hair bristle. This is, in my opinion, fairly gross and probably a non-starter as other options go—not only can it be seen as a cruel practice to pluck the hair off a hog's body to make bristles, it's also unhygienic as hog’s hairs are hollow and as such are a refuge for bacteria.


As I said, gross.


For the Soseas Bamboo Toothbrush, we decided to opt for Rayon, a semi-synthetic polymer in fact derived from bamboo that takes less time than cotton to biodegrade in nature.

You might not know what Rayon is but you’ve probably worn it, clothing labeled as made from bamboo are often in fact made from Rayon. Rayon strikes a balance between being hard wearing without having a persistent negative impact on the environment like it’s altogether harsher pal, Nylon.


So there you have it, we’ve covered all the reasons why you should swap your old plastic toothbrush for a pristine and earth-loving bamboo brush—from sourcing and safety concerns to disposal, bamboo beats plastic every time.

Just make sure you look out for hidden sources of plastic in the bristles and packaging when you’re selecting your bamboo toothbrush.
