The term 'snake TOOTH' can be broken down into two words, 'FANG' and 'TOOTH'. The word 'FANG' is a four-letter word which refers to the long, sharp teeth of a snake. These teeth are used for hunting and defense, and are usually found in the upper jaw of a snake. The word 'TOOTH' refers to the hard, bony structures found in the mouth of a snake which are used for grinding food. Together, the two words form the term 'snake TOOTH', which is used to describe the combination of fangs and teeth found in a snake's mouth.
