Neutralization of Acids and Bases

[Kazmo]

Tooth enamel contains a compound with the formula Ca₁₀(PO₄)₆(OH₂). Why can a child's teeth be damaged over time if the child is put to bed with a bottle of milk? (HINT: Milk can break down over time to produce lactic acid.

 

I was thinking the solution would be like this : Acid + Base = Water + Salt

 

Acid (Lactic acid) : C₃H₆O₃

Base (Tooth enamel compound)

 

C₃H₆O_{3 +} Ca₁₀(PO₄)₆(OH₂) ----> H₂O + ????????

 

Thanks for your help, I appreciate it!
