It’s a shame cinnamon toothpaste is much less common than mint. Like a couple of options exist, but I don’t buy because they either lack fluoride (Grants), are way overpriced (HiSmile, Marvis) or are a hassle to buy from somewhere other than a supermarket/involve third party sellers.

If there were basic fluoride cinnamon tubes at Colesworth though I’d probably give it a go.

Unflavoured toothpaste with fluoride would also be a good thing to have.

(Kids paste is milder but I think lower in fluoride and also not very appealing to me.)
