How come human teeth fall out if you don't brush them, yet animal teeth seem to last years without any form of cleaning?
The answer is simple:
- Animals in nature don't have refined sugars in their diets.
- Their diet is not as soft as ours (they don't get to cook their meat or vegetables) and therefore they are less prone to dental problems. Plus this also helps them "brush" their teeth in a way.
Hope this helps!
