I did a little research and found an Australian toothbrush (made in China, of course) the handle is made from sustainable bamboo with cellulose bristles that are supposedly compostable (I am not too sure about the bristles). The brand is - The Original Environmental Toothbrush and I order them online; $36 for a box of 12. The order was delivered in four days, each toothbrush was in a cardboard box all 12 inside another cardboard box and delivered in a paper parcel (no plastic in sight ) :)
I purchased the soft brushes and they were fine, I guess it felt a little unfamiliar and I am getting to that age where change is unnerving but, I liked them. My middle daughter was the first to lose her old plastic brush and have to make the swap (she literally lost her toothbrush, how is that possible) the wooden brush reminded her of the paddle stick the doctor holds your tongue down with and the recall made her gag. I cuddled her, smiled, did nothing; she got over it. My son didn't understand why he had to use 'a stick' to brush his teeth and constantly advise me it gave him splinters (large eye roll).
Now toothpaste was a whole other can of worms. I used Grants natural toothpaste (in plastic) and I could not get any of my family to leave Colgate for that, how on earth was I going to get them over to baking soda? Even I was not looking forward to this swap.
The tube ran dry and the experiments began; I was the guinea pig for them all. My current mix is aluminium free baking soda and a small amount of celtic sea salt (both purchased in my jars from The Source store in town) laced with organic peppermint (add to suit your taste). The baking soda cleans and polishes, the salt kills bacteria and remineralises, apparently? While the peppermint is meant to refreshen and hide the disgusting taste.
I don't really like salt, I don't even add it to my food and I found this, YUCK!!!! I did persist and have gotten use to it. I just dip my toothbrush into my small jar of prepared power and my mouth and teeth do feel really clean and breath is good. (I hope)
My family... well.... this was the last straw for my son he hit the roof and no one else was not too happy with losing their toothpaste either. So toothpaste was their one plastic sin and if they ever want something in plastic now I just ask if they are ready to swap it for their toothpaste; they never are.
There are a couple of products available online in tins and jars. Lush has tablets, but I am use to my mix and it is super cheap, easy and my teeth feel really clean. The other recipes I tried had too many ingredients without much taste improvement. Some people just use the baking soda or bicarb (make sure it is aluminium free) but I think you need the salt to kill bacteria and peppermint for flavour.
I use one tablespoon aluminium free baking soda, 1/4 teaspoon fine celtic salt, 14 drops peppermint, mix in a miniature jam jar.
"In Australia, over 30 million toothbrushes are used and disposed of by Australians each year, amounting to approximately 1000 tonnes of landfill each year. The plastic they’re made of won’t break down in our lifetime. Nor within the lifetime of our children. Imagine that on a global scale." The Environmental Toothbrush.
