Solid toothpaste – one of the zero waste products that generates more doubts and questions than any other.

Will it clean my teeth as effectively as traditional toothpaste? Will it effect my teeth’s enamel? Will it taste good? Will it foam up as usual?

To help you find the answers to your questions we want to share the following in this post:

  1. The advantages of solid natural toothpaste.

  2. Dentists’ opinions about these types of toothpastes.

  3. Our recommendations, so that you find the best natural solid toothpaste to suit your needs.

The advantages of natural eco-friendly toothpastes over traditional toothpaste

Natural solid toothpaste is becoming a more and more commonly used alternative to conventional toothpastes for various reasons:

  1. They are free from toxic ingredients:

Regular toothpastes contain ingredients that are potentially toxic and harmful to our health, such as carcinogens and endocrine disruptors. Solid toothpastes that are made from natural ingredients (rather than synthetic ones) are free from these compounds.

  1. They don’t contain microplastics:

Some cosmetics, such as toothpastes, contain intentionally added microplastic particles in their make-up. Although the EU has taken steps towards banning them, the big well-known brands continue to include them in their formulations.

  1. They’re zero waste:

Whichever format you choose (solid toothpaste, tooth powder or chewable dental care tablets) natural toothpastes don’t come packaged in plastic, but instead in glass, paper or in an aluminium tin, and there are also refills available.

Natural eco-friendly toothpaste: What do dentists say about it?

Despite the evident advantages, one of the biggest doubts people have when considering a natural solid toothpaste is, whether it will clean and take care of their teeth and gums as well as traditional toothpastes.

Unfortunately, we haven’t found many studies on the topic, but we have found some dentists’ opinions, like this one from a dental clinic in Barcelona, that points out the advantages using natural toothpaste has for our health: “Natural toothpastes offer several advantages when compared with conventional toothpastes. Being formulated with natural ingredients, often including a base of essential oils (such as coconut oil) and herbs, such as some organic, aromatic, pesticide-free herbs etc. they do not damage dental enamel, they help reduce gum inflammation and they do not cause gastrointestinal problems”.

Faced with a lack of information, we have asked our dentists and they have told us that, if you don’t have any specific problems with your teeth and gums that would benefit from using a particular toothpaste (such as sensitivity), you can use whatever toothpaste you choose.

In fact Marion, our co-founder, has been using solid natural toothpaste for years along with a wooden toothbrush and natural silk dental floss and her dentist can assure us that her teeth are perfectly well cared for.

This is because, as they have always told us, in order to have good dental hygiene the important thing is to follow these steps:

  1. ALWAYS brush your teeth after every meal.

  2. Brush gently for at least 2 minutes from the gum line to the tip of your teeth, never the other way round (in order to not damage your gums).

  3. Use dental floss regularly to eliminate any food left stuck between your teeth.

  4. For a better clean, combine dental floss with interdental brushes (unfortunately we have not yet found plastic-free options here, however we are still searching).
