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 HAP - a mineral which protects your teeth's outer layer. HAP toothpaste can reduce tooth sensitivity, rebuild tooth enamel, and prevent tooth decay.

Now they sell a large range of HAP-containing products, such as restorative toothpaste and children's toothpaste.
