Wisdom teeth 

The wisdom teeth are the teeth right at the back of the mouth either side of the jaw on the top and bottom.  The wisdom tooth is in fact the third molar and is the last tooth to grow. It commonly appears between ages 17 to 21.

Wisdom teeth grow between 17 and 21 years of age

So when the wise man (wisdom) went into the cave mouth he took a lunch of four (4) fruits as he knew no dogs would steal it.

Wisdom teeth are found at the very back of the mouth as the third molars
