With an Instron hydraulic press. But I don't think that's what you mean...
"Hardness" and "softness" of teeth usually refers to how likely someone is to get cavities. In my opinion, this has more to do with diet and hygiene than any native hardness or softness of the teeth. The enamel layer is made of crystalline hydroxyapatite and it is just about uniformly dense fromone person to the next. A cavity starts as a demineralization. Once the enamel is demineralized, I guess the tooth could be said to be softer in that local area, but I don't think that it was softer prior to the initiation of the cavity.

there is no such thing as soft teeth. no one is born with soft teeth. no one has harder teeth than the next person. this is a classic cop out excuse for not brushing and flossing. people like to blame circumstances rather than themselves for their problems.
