Hello,

I am Looking For THE chemical formula of tooth erosion. Can anyone help me please? I suppose This is  hydroxyapatite and acid. Ca5(PO4)3OH and ??

There is no such thing as a single "formula" for the dissolution of tooth tissues. There are many possible acids involved and many different reactions occurring, each with its own reaction equation and equilibrium. It is not even possible to simply state what the products are, as they depend on the acid and pH.

Hello Borek,

Thank you for your reply.
Is there no general formula To describe tooth erosion, THE process of demineralisation?

Saliva <> hydroxyapatite

At a pH value of less then 5,5.

Thank you in advance
