Can your stomach digest your teeth?

Answer 1

The connective tissues of the pulp will be completely digested, the dentine which is more porous and fragile to acid attack will dissolve at a much slower rate but it too will eventually be dissolved by the gastric acids.

Now, the enamel is of much discussion; but most dentists notice lingual erosion (dissolved enamel on the surfaces of teeth facing the tongue) in patients who suffer from a lot vomitting (like pregnant women). This suggests that a strong acid attack can demineralise and erode the enamel structure, but the process is long and slow. Out of the whole 24hr digestion cycle food is only in the areas of extreme pH for apx. 6 hours.

So the answer to your question is that your stomach can digest a tooth to some extent, by the time it is found in your feces the enamel structure may be in pieces or with nice big holes in it, it will be hollowed out by the pulp being dissolved and there will be little dentine left.
