Eli5: why is when a bone shatters it can rebuild itself but when a tooth gets a hole in it it just keeps eating away at it
In: Biology
Your teeth are on the outside of your body, so they are exposed to external bacteria, acids that you eat, dirt, etc. They also aren’t made of “teeth cells” so basically they are almost inert (not alive really). Your bone however is safe and sound on the inside of your body, surrounded by all the good nutrients, andtibodies, blood supply etc that bones need to stay healthy. Bones also are made of cells, so they are alive and can repair themselves
Like a natural stone vs concrete. One will erode, the other will crack and degrade, but can be easily repaired.
