Nouns are words that name people, things, places,
animals, etc.
The sentence starts with all, which indicates that not one but more than one tooth has to be removed.
Option B: 'Teeth' is the plural form of the noun 'tooth'. Hence, option B is correct.
Option A: 'Tooths' is not the plural form of 'tooth'. It must be formed by replacing 'oo' and not adding 's' to the noun.
Options C: 'Tooth's' is a singular noun (tooth) in the possessive case ('s refers to possession).
Option D: Teeth's is a plural noun in the possessive case. But, the sentence does not indicate any possession.
Hence, these options are wrong.
