Doktor gigi memeriksa gigi bongsu sebelum mencabut gigi itu.

Yes, literally it is tooth doctor, and that is the normal Malay way to say dentist.

• doktor = doctor
• gigi = tooth / teeth

Malay often makes noun compounds this way, where the second noun describes the first:

• doktor gigi = dentist
• kereta api = train, literally fire vehicle
• rumah sakit in Indonesian = hospital, literally sick house

So doktor gigi is a set expression, not a strange or funny phrase in Malay.

Malay does not use articles like a, an, or the the way English does.

So:

• doktor gigi can mean a dentist, the dentist, or just dentist, depending on context.

Malay usually leaves definiteness to context, or sometimes adds words like:

• itu = that / the previously mentioned one
• seorang = a / one person

For example:

• Seorang doktor gigi = a dentist
• Doktor gigi itu = the dentist / that dentist

In your sentence, just doktor gigi is completely natural.

Because it is part of two different noun phrases:

• doktor gigi = dentist
• gigi bongsu = wisdom tooth
• gigi itu = that tooth / the tooth

So the first gigi belongs to the profession name doktor gigi, and the later gigi words refer to the tooth being examined and removed.

No. Bongsu normally means youngest, especially the youngest child in a family.

But gigi bongsu is the standard Malay term for wisdom tooth. It is an established expression, not a word-for-word translation of English.

So learners should treat gigi bongsu as a vocabulary item:

• gigi = tooth
• gigi bongsu = wisdom tooth

Memeriksa is the active transitive verb form built from the root periksa.

• root: periksa = inspect, examine
• active verb: memeriksa = to examine

The prefix meN- is very common in Malay and often creates active verbs.

So:

• Doktor gigi memeriksa gigi bongsu = The dentist examines/examined the wisdom tooth.

In casual speech, people may sometimes say periksa without the prefix, but memeriksa is the more standard written form here.

The subject is understood to be the same as in the first clause: the dentist.

So:

• Doktor gigi memeriksa gigi bongsu sebelum mencabut gigi itu means
• The dentist examined the wisdom tooth before pulling it out.

Malay often omits a repeated subject when it is clear from context.

So after sebelum:

• mencabut = pulling out / to pull out

It is understood as:

• sebelum doktor gigi itu mencabut gigi itu

but repeating everything would sound heavier and is often unnecessary.

All of those are possible depending on context.

The root idea of cabut is pull out / yank out / remove by pulling.

So:

• mencabut gigi = to extract a tooth / pull out a tooth
• mencabut rumput = pull up grass
• mencabut palam = unplug a plug

In a dental sentence, mencabut gigi is the normal way to say extract a tooth.

Gigi itu means that tooth or the tooth. It refers back to the wisdom tooth mentioned earlier.

Malay often repeats the noun plus itu for clarity:

• gigi itu = that tooth / the tooth

You could also see:

• mencabutnya = pulling it out

That is possible, but gigi itu is clearer and very natural in writing.

An even more explicit version would be:

• mencabut gigi bongsu itu = extracting that wisdom tooth

Not always.

Itu can mean:

• that
• the
• sometimes just a marker that the noun is already known in the conversation

So in this sentence, gigi itu could be understood as:

• that tooth
• the tooth

English translation depends on context, not just the dictionary meaning of itu.

Yes, gigi can mean either tooth or teeth, depending on context. Malay nouns usually do not change form for singular vs. plural.

So:

• gigi = tooth / teeth
• doktor gigi = dentist
• gigi bongsu = wisdom tooth / wisdom teeth in the right context

In this sentence, context strongly suggests a single tooth, especially because of gigi itu referring back to one specific tooth.

Mostly yes. This sentence follows a very familiar order:

• Doktor gigi = subject
• memeriksa = verb
• gigi bongsu = object
• sebelum mencabut gigi itu = time clause

So the pattern is roughly:

Subject + Verb + Object + before + Verb + Object

That makes this sentence quite approachable for English speakers.

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

So memeriksa can mean:

• examines
• examined
• is examining
• was examining

The time is usually understood from context or added time words such as:

• semalam = yesterday
• sekarang = now
• esok = tomorrow
• sudah = already
• akan = will

Without extra context, the sentence is tense-neutral.

Yes. Sebelum means before, and it can be followed by either a shorter verb phrase or a fuller clause.

Your sentence has the shorter style:

• sebelum mencabut gigi itu = before pulling out the tooth

A fuller version would be:

• sebelum doktor gigi itu mencabut gigi itu = before the dentist pulled out the tooth

Both are grammatical. The shorter one is common when the subject is obvious.

In standard Malay as used in Malaysia and Brunei, doktor gigi is the normal spelling.

• doktor = standard Malay spelling
• dokter = Indonesian spelling

So if you are learning Malay, use doktor gigi. If you are reading Indonesian, you will often see dokter gigi.
