Sangi is a dental health company founded in Japan during the 1970s.
After some years of research, they launched their first product in 1980, which was the world's first toothpaste containing hydroxyapatite - a mineral which protects your teeth's outer layer. Hydroxyapatite toothpaste can reduce tooth sensitivity, rebuild tooth enamel, and prevent tooth decay.
Now they sell a large range of hydroxyapatite-containing products, such as whitening mouthwash, restorative toothpaste and children's toothpaste.
