Does it contain fluoride? It contains 1000 ppm of fluoride, as recommended by the WHO and the UFSBD, to effectively protect teeth from cavities. 🙂 Why fluoride? Fluoride (sodium fluoride in our ingredient list) is an excellent oral hygiene active ingredient with numerous benefits for dental hygiene: – helps fight against the formation of cavities – helps protect against the formation of dental plaque – helps with cleaning, deodorizing and oral protection. From what age are our toothpastes suitable? For children aged 3 to 6, we recommend our strawberry kids' toothpaste. From age 7, we recommend switching to our mint or lemon toothpaste. If the child prefers to stick with strawberry, they can, but we recommend applying a little extra to the toothbrush. What is the packaging of the refills made of? The refills are made from 83% paper sourced from sustainably managed forests and FSC® certified, and 17% PE to ensure waterproofing and moisture protection. 🙂 And they're recyclable in the paper recycling stream! ♻️ What material is the refillable bottle made of? The bottle is made of safety glass. Glass offers a long lifespan and is reinforced with a thin layer of plastic to prevent glass shards from falling into the shower or onto the sink. What quantity of gel toothpaste is equivalent to one refill of powdered toothpaste? With an 8g refill of toothpaste, you get 80ml of foaming toothpaste. This is equivalent to a standard tube of toothpaste. How do I activate my pump? You can remove it and then replace it by screwing it in the opposite direction until you hear a small click. Once you hear the click, screw it in the correct direction and all the way! That should normally solve the problem. If not, feel free to email us at [email protected] 🙂 Should I fill my bottle with hot or cold water? To ensure your toothpaste mixes well, we recommend using lukewarm water, neither too hot nor too cold. How long can I store my powdered toothpaste that needs to be diluted? Unopened, a toothpaste refill can be stored for 3 years. When you have diluted the powder in the refill with tap water, you can store your toothpaste for 3 months. Are our toothpastes recommended for sensitive gums? Our toothpastes are not specifically formulated for sensitive teeth, and we haven't conducted any usage tests for that purpose. However, they are composed of only very gentle, non-abrasive ingredients with remineralizing and enamel-protecting properties. The toothpaste is made with 99% naturally derived ingredients, is Ecocert COSMOS Natural certified, and has received an Excellent rating on Yuka. What is the difference between this and major toothpaste brands? Our aim is to offer you a toothpaste that's both healthy for you and the environment, and affordable. We designed our powdered toothpaste to be diluted so that it contains a maximum of naturally derived ingredients (99%), is lightweight (8g), and recyclable (paper recycling). No more throwing away your plastic/aluminum tube! Just refill.
