Sebelum mencabut geraham, dokter gigi memakai bius.

Sebelum means before. It introduces the action that happens earlier:

• Sebelum mencabut geraham = Before pulling out the molar
• dokter gigi memakai bius = the dentist uses anesthesia

So the structure is:

• Before doing X, subject does Y

Indonesian often puts the before-clause first, just like English can.

In Indonesian, the subject is often left out when it is already clear from context.

Here, the full idea is understood as:

• Before (the dentist) pulls out the molar, the dentist uses anesthesia.

Because the main clause already gives us dokter gigi, Indonesian does not need to repeat it in the first clause.

If the subject were different, Indonesian would usually make that clearer.

Mencabut means to pull out, to uproot, or to extract, depending on context.

In dental context, mencabut gigi/geraham means:

• to pull a tooth
• to extract a molar

It comes from the root cabut = pull out.
The prefix men- makes it an active verb:

• cabut = pull out
• mencabut = to pull out / to extract

Because geraham specifically means molar.

So:

• gigi = tooth / teeth
• geraham = molar

This sentence is more specific than just saying tooth.

You may also hear:

• gigi geraham = molar tooth

But in context, geraham by itself is completely natural.

Literally, it is:

• dokter = doctor
• gigi = tooth/teeth

So dokter gigi literally means tooth doctor, which is the normal Indonesian way to say dentist.

This is a very common Indonesian pattern:

• dokter anak = pediatrician
• dokter hewan = veterinarian
• dokter gigi = dentist

Yes, memakai can mean both to wear and to use, depending on the object.

Examples:

• memakai baju = to wear clothes
• memakai komputer = to use a computer
• memakai bius = to use anesthesia

So here it definitely means use, not wear.

Bius means anesthetic or anesthesia.

In this sentence, memakai bius means the dentist uses anesthesia/anesthetic before extracting the molar.

Depending on context, Indonesian can also say:

• obat bius = anesthetic drug
• dibius = to be anesthetized
• membius = to anesthetize someone

Indonesian does not normally use articles like English a/an/the.

So:

• dokter gigi can mean the dentist or a dentist
• geraham can mean a molar or the molar
• bius can mean anesthetic/anesthesia

The exact meaning depends on context, not on articles.

That is why one Indonesian sentence can correspond to several natural English translations.

Indonesian verbs do not change form for tense the way English verbs do.

So memakai can mean:

• uses
• is using
• used
• will use

Context tells you the time.

In this sentence, it sounds like a general fact or habitual procedure, so English often translates it as:

• Before extracting a molar, the dentist uses anesthesia.

The comma separates the introductory clause from the main clause:

• Sebelum mencabut geraham, = introductory time clause
• dokter gigi memakai bius. = main clause

This is similar to English:

• Before pulling the molar, the dentist uses anesthesia.

In writing, that comma is natural and helpful.

Yes. That is also correct and natural.

Compare:

• Sebelum mencabut geraham, dokter gigi memakai bius.
• Dokter gigi memakai bius sebelum mencabut geraham.

Both mean the same thing. The difference is mostly emphasis and style:

• starting with sebelum... emphasizes the time relationship first
• starting with dokter gigi... emphasizes the subject first

By itself, geraham does not clearly mark singular or plural.

Indonesian nouns usually do not change form for number. So geraham could mean:

• a molar
• molars

But in this sentence, the most natural interpretation is a molar, because it refers to a specific dental procedure.

If Indonesian wants to make plurality explicit, it can use reduplication:

• geraham-geraham = molars

Yes, but mencabut is a very natural choice here.

Some possibilities:

• mencabut geraham = pull out/extract a molar
• mencabut gigi = pull out/extract a tooth

In medical or formal contexts, you might also see terms related to extraction, but mencabut is common, clear, and everyday Indonesian.

It can be understood either way, because Indonesian often leaves that open unless context makes it specific.

It could mean:

• a general statement: Before extracting a molar, a dentist uses anesthesia
• a specific event: Before extracting the molar, the dentist used/is using anesthesia

Without more context, many learners should read it as a general procedural statement.
