Question

Select the correct plural noun from the given singular form of the noun:
All my _____ have to be removed. (tooth)
a. tooths
b. teeth
c. teeth's
d. tooth's

Answer 1

Hint: A tooth is a hard, calcified structure found in the jaws of most of the vertebrates and is used to break down food. Tooth is generally used to refer to a single structure that is embedded into our gums for chewing and tearing purposes.

Complete answer:
Tooths is not a dictionary word and doesn’t have any meaning. Teeth’s and tooth's are the words which are used when we are referring to them ( singular and plural respectively). Hence these words don’t serve us the plural of the word 'tooth' nor provide a meaning to the sentence. Options, tooths, teeth's, and tooth’s are hence marked out.
Teeth is used to refer to more than one tooth. It refers to the multiple, hard, bony enamel- coated structures in our jaws. Teeth is sometimes also used to refer to the projecting part of a tool or instrument. Unlike most of the words in English, the plural of tooth doesn’t require addition of -s or -es.

Example: He should have taken care of his teeth when he was young to have avoided multiple fillings.

Note: Avoid adding unnecessary -s or -es to create plural forms of words.
