Bicarb-free toothpastes clean with gentle ingredients like calcium carbonate, hydroxyapatite, sea salt and food-grade hydrogen peroxide.
Bicarb is in lots of natural toothpastes. It's a natural ingredient and great for whitening and lifting surface stains. But it's not for everyone. It can be a bit harsh for sensitive gums. So I went through our toothpaste section and found these great bicarb-free options, and like every toothpaste I sell, they're all fluoride-free too.
Is bicarb safe in toothpaste?
Yes. Bicarb, which is also known as sodium bicarbonate on the back of the label or baking soda in the kitchen, is one of the gentlest cleaning ingredients used in toothpaste. It's just a bit much for sensitive mouths and gums.
What are the best bicarb alternatives?
Bicarb-free toothpastes clean with other natural ingredients like calcium carbonate (which is natural chalk), hydroxyapatite, sea salt, silica and food-grade hydrogen peroxide. Some use traditional plants too, like ratanhia root.
5 of my favourite bicarb-free toothpastes
Grants Mild Mint
Grants Mild Mint is the original Grants toothpaste, first made in 1984. It gently cleans with calcium carbonate and has organic aloe vera to soothe the gums. It has a soft mint taste the whole family can use. If you love Grants, every flavour is in my guide to Grants toothpaste. Nectarine Rating
