The plural of tooth is a topic that often stumps learners of English. While it may seem like the plural should be “toothes,” that is not the case.
Teeth are an essential part of the human body and are necessary for chewing food and speaking properly. They are also a vital aspect of dental health and hygiene. Understanding the correct plural of tooth is crucial for clear communication, especially in medical and dental fields. Additionally, knowing the correct plural can help avoid confusion and potential misunderstandings. In this article, we will explore the correct plural of tooth, and how it is used in everyday language.
Plural of Tooth
Definition and Plural of Tooth
A tooth is a hard, calcified structure that is found in the jaws of many vertebrates and is used to break down food by chewing. Teeth are an essential part of the digestive system and play a crucial role in the process of digestion.
The plural of tooth is teeth. This is a common irregular plural in English, and it is important to use the correct form when referring to more than one tooth.
There are different types of teeth in the human mouth, each with a specific function. The four main types of teeth are incisors, canines, premolars, and molars. Incisors are the front teeth used for biting and cutting food, while canines are the sharp teeth used for tearing and ripping. Premolars and molars are used for grinding and crushing food.
It is important to take care of your teeth to maintain good oral health. Brushing and flossing regularly, as well as visiting the dentist for regular check-ups, can help prevent tooth decay and other dental problems.
When to Use Tooth and Its Plural Form
The word “tooth” is a noun that refers to one of the hard bony appendages borne on the jaws or walls of the mouth or pharynx in vertebrates. The plural form of “tooth” is “teeth.” It is important to use the correct form of the word depending on the context.
When referring to a single tooth, use the singular form “tooth.” For example, “She has a cavity in her tooth.” When referring to more than one tooth, use the plural form “teeth.” For example, “He lost two teeth in the accident.”
It is important to note that “tooths” is not a correct plural form of “tooth.” The only time you would use “tooth” with an “s” at the end is if there is an apostrophe before the “s” to indicate a “tooth” possessing something. For example, “The tooth’s root was infected.”
In some cases, the plural form “teeth” can also be used to refer to a set of teeth. For example, “She has a beautiful set of teeth.” However, when referring to a specific set of teeth, it is more common to use terms such as “upper teeth” or “lower teeth.”
Examples of Tooth and Its Plural Form in Sentences
When it comes to the plural form of “tooth,” there is only one correct spelling: “teeth.” Here are some examples of “tooth” and its plural form in sentences:
- She had a toothache and needed to see a dentist.
- The dentist pulled out one of her teeth because it was decayed.
- Sharks grow a new set of teeth every two weeks to replace worn teeth.
- He had lost all of his teeth in a car accident and needed dentures.
- The baby was teething and had swollen gums.
- The dentist counted her teeth to make sure they were all healthy.
- The dentist filled a cavity in one of his molars.
- She brushed her teeth twice a day to prevent cavities.
- The orthodontist recommended braces to straighten her crooked teeth.
- The dentist gave her a toothbrush and floss to maintain good oral hygiene.
As you can see, “teeth” is used as the plural of tooth in all of these sentences. It’s important to note that “tooths” is not a proper way to pluralize “tooth.” The only time you would use “tooth” with an “s” at the end is if there is an apostrophe before the “s” to indicate a “tooth” possessing something.
Plural Noun Rules for Regular Nouns
In English, most regular nouns form their plural by simply adding an “s” at the end of the singular form. For example, the plural of “book” is “books,” the plural of “car” is “cars,” and the plural of “computer” is “computers.”
However, there are some exceptions to this rule. When a noun ends in “s,” “x,” “z,” “ch,” or “sh,” you need to add “es” to the end to form the plural. For example, the plural of “box” is “boxes,” the plural of “buzz” is “buzzes,” and the plural of “church” is “churches.”
If a noun ends in a consonant followed by a “y,” you need to change the “y” to an “i” and add “es” to form the plural. For example, the plural of “city” is “cities,” the plural of “baby” is “babies,” and the plural of “sky” is “skies.”
For nouns ending in “o,” the plural form can be either “es” or “s.” For example, the plural of “potato” can be “potatoes” or “potatos,” and the plural of “photo” can be “photos” or “photographs.”
It is important to note that irregular nouns do not follow these rules and must be memorized. For example, the plural of “tooth” is “teeth,” the plural of “child” is “children,” and the plural of “foot” is “feet.”

Plural Nouns vs. Possessive Nouns
When it comes to the plural of “tooth,” the correct form is “teeth.” However, when discussing possession, it is important to understand the difference between plural nouns and possessive nouns.
Plural nouns simply refer to more than one of something, while possessive nouns indicate ownership or association with someone or something. For example, “teeth” is a plural noun, while “the teeth’s enamel” is a possessive noun.
To form a possessive noun, an apostrophe and “s” are added to the end of the noun. However, there are some exceptions to this rule, such as with plural nouns that already end in “s,” where only an apostrophe is added.
Here are some examples of plural and possessive nouns:
| Plural Noun | Possessive Noun |
|---|---|
| Teeth | The teeth’s enamel |
| Dogs | The dogs’ toys |
| Cars | The cars’ engines |
| Children | The children’s books |
