haisya ga oyasirazu wo nukimasu.

It is read:

はいしゃ が おやしらず を ぬきます。

• 歯医者（はいしゃ） = dentist
• 親知らず（おやしらず） = wisdom tooth / wisdom teeth
• 抜きます（ぬきます） = pulls out, extracts

が marks the grammatical subject, meaning the person who does the action.

So in this sentence:

• 歯医者が = the dentist is the one performing the action

A learner might expect は, but が is completely natural here when identifying who does the action.

Very roughly:

• 歯医者が親知らずを抜きます。 = The dentist will extract the wisdom tooth.
• 歯医者は親知らずを抜きます。 would sound more like As for the dentist, they extract wisdom teeth or would set up the dentist as the topic.

を marks the direct object, meaning the thing directly affected by the action.

Here:

• 親知らずを抜きます = extracts the wisdom tooth

So the structure is:

• 歯医者 = doer
• が = subject marker
• 親知らず = thing being extracted
• を = object marker
• 抜きます = extracts

親知らず is the common Japanese word for a wisdom tooth.

Literally, it is often explained as something like tooth unknown to one’s parents, because wisdom teeth usually come in after childhood.

A few useful notes:

• It is often written in kana as おやしらず
• It can refer to a wisdom tooth or wisdom teeth in general
• In this sentence, the exact number is not explicitly stated, so English may translate it as either the wisdom tooth or wisdom teeth, depending on context

The dictionary form is 抜く（ぬく）, which means to pull out, extract, or remove by pulling.

For teeth, 抜く is the normal verb:

• 歯を抜く = to pull a tooth
• 親知らずを抜く = to extract a wisdom tooth

So 抜きます is the polite present/future form of 抜く.

In medical or everyday Japanese, this is the standard way to talk about tooth extraction.

Japanese polite non-past forms like 抜きます can mean either:

• present / habitual: extracts, pulls out
• future: will extract, is going to extract

The exact meaning depends on context.

So this sentence could mean:

• The dentist extracts wisdom teeth.
  or
• The dentist will extract the wisdom tooth.

If this is about a scheduled procedure, English would often use will extract or is going to extract.

It can mean either in some contexts, but here it most naturally means the dentist as a person, because it is followed by が and performs the action 抜きます.

So in this sentence:

• 歯医者が = the dentist does the extraction

If someone says:

• 歯医者に行く = go to the dentist / go to the dentist’s office

there, it can feel more like the dentist’s office or the dentist in a broader sense.

Yes, but the nuance changes a little.

• 歯医者（はいしゃ） = common, everyday word for dentist
• 歯科医（しかい） or 歯科医師（しかいし） = more formal/professional terms

So:

• 歯医者が親知らずを抜きます。 sounds natural and everyday
• 歯科医が親知らずを抜きます。 sounds more formal

Yes. Japanese nouns usually do not change form for singular vs. plural.

So 親知らず can mean:

• a wisdom tooth
• wisdom teeth

The actual number comes from context.

If you wanted to be explicit, you could add a number, for example:

• 親知らずを一本抜きます。 = extract one wisdom tooth
• 親知らずを二本抜きます。 = extract two wisdom teeth

The spaces are usually added only for learners.

Normal Japanese writing would be:

歯医者が親知らずを抜きます。

Japanese does not normally use spaces between words the way English does. Textbooks and beginner materials often add spaces to make the sentence structure easier to see.

Yes, very often.

In natural conversation, if it is already clear that the dentist is the one doing it, Japanese might simply say:

親知らずを抜きます。

This could mean:

• We’ll extract your wisdom tooth
• The dentist will extract the wisdom tooth
• I’ll extract the wisdom tooth

depending on context.

Japanese often leaves out information that is understood from the situation.

Yes, it can be natural, but context matters.

If someone is explaining what will happen at the dentist, this works fine:

• 歯医者が親知らずを抜きます。 = The dentist will extract my wisdom tooth.

However, in real conversation, Japanese often prefers slightly more contextual or personal phrasing, such as:

• 親知らずを抜きます。 = I’m having my wisdom tooth removed / They’re removing my wisdom tooth
• 歯医者で親知らずを抜きます。 = I’m getting my wisdom tooth removed at the dentist

So the original sentence is grammatically correct and natural, but actual spoken Japanese may sometimes phrase it differently depending on what the speaker wants to emphasize.

The structure is:

[subject] が [object] を [verb]

So here:

• 歯医者 = subject
• が = subject marker
• 親知らず = object
• を = object marker
• 抜きます = verb

This is one of the most important basic Japanese sentence patterns to learn.
