FAQ: Tambayoyin da ake yawan yi

Q1: Ta yaya hydroxyapatite ya kwatanta da fluoride a cikin man goge baki?

Duk da yake dukansu suna hana kogo, hanyoyin su gaba ɗaya sun bambanta. Fluoride yana mu'amala da yau don haifar da wani shinge a saman hakori da ake kira fluorapatite, wanda ke da matukar juriya ga harin acid. Hydroxyapatite, a gefe guda, yana aiki azaman kayan maye kai tsaye. Yana cika jiki a cikin ƙananan ramuka da kuma asarar ma'adanai a cikin enamel.
