Plak dan karang gigi menempel di sekitar tambalan.

Plak means plaque. It is basically a borrowed word from English, adapted to Indonesian spelling.

Karang gigi means tartar or calculus on the teeth.

• gigi = tooth/teeth
• karang literally can mean coral or something hard/crust-like, which helps explain why the phrase refers to hardened buildup on teeth.

So plak dan karang gigi means plaque and tartar.

By itself, karang usually does not mean dental tartar. It has other meanings, such as coral.

To specifically say tartar on the teeth, Indonesian uses the full phrase karang gigi. This is very common in Indonesian: a noun is often clarified by another noun after it.

So:

• karang = coral / other meanings depending on context
• karang gigi = dental tartar

Menempel means to stick, to adhere, or to cling.

In this sentence, it describes plaque and tartar sticking to or adhering around the filling.

A useful thing to know:

• base/root idea: tempel = stick/attach
• menempel = an intransitive verb, often meaning to stick or be attached

So Plak dan karang gigi menempel ... means Plaque and tartar stick / are attached ...

Indonesian often does not use a separate verb like is/are where English would.

So instead of saying something like Plaque and tartar are stuck around the filling, Indonesian can simply say:

Plak dan karang gigi menempel di sekitar tambalan.

This is completely normal. Indonesian frequently leaves out is/are/am when the meaning is clear.

Di sekitar means around, in the area around, or in the vicinity of.

Breakdown:

• di = a preposition meaning in / at / on, depending on context
• sekitar = surroundings / around / approximately depending on use

Together, di sekitar means around or in the area around something.

So:

• di sekitar tambalan = around the filling

Because here di is a preposition, not a prefix.

In Indonesian:

• di as a preposition is written separately: di rumah, di meja, di sekitar
• di- as a verb prefix is written attached: ditutup, dibuka, dibersihkan

So di sekitar is correct because it means around/in the area of, not a passive verb form.

Tambalan means a patch, repair, or filling, depending on context.

In a dental context, tambalan means a dental filling.

It comes from the root tambal, which has the idea of patching or mending. The ending -an often forms a noun, so tambalan becomes something used as a patch/filling or the result of patching.

In this sentence, the dental meaning is the natural one:

• tambalan = filling

No. Tambalan is broader than that.

It can mean:

• a patch on clothes
• a repair patch
• a filler
• a dental filling

The context tells you which meaning is intended. Because the sentence talks about plaque and tartar, the dental meaning is obvious here.

It could, if the speaker wanted to be extra explicit. Tambalan gigi means tooth filling / dental filling.

But in this sentence, just tambalan is already clear because of the dental context created by plak and karang gigi.

So:

• tambalan = filling/patch (general word)
• tambalan gigi = dental filling (more explicit)

This follows the normal Indonesian pattern:

Subject + Verb + Prepositional phrase

So:

• Plak dan karang gigi = subject
• menempel = verb
• di sekitar tambalan = location phrase

That is very natural Indonesian word order.

Indonesian does not use articles the same way English does. There is no direct equivalent that must appear in every sentence for a/an/the.

So:

• plak can mean plaque
• karang gigi can mean tartar
• tambalan can mean a filling or the filling

The exact meaning depends on context.

If needed, Indonesian can add words to make things more specific, such as:

• sebuah tambalan = a filling (less likely in everyday dental phrasing, but possible)
• tambalan itu = that/the filling
• tambalannya = the filling / its filling, depending on context

But in many cases, Indonesian simply leaves this unspecified.

It can be understood as a mass noun, similar to English plaque. Indonesian nouns usually do not change form for singular vs. plural.

So plak is fine as-is.

Likewise, karang gigi does not need a special plural ending. Indonesian normally relies on context rather than changing the noun form.

Yes. Depending on style and nuance, speakers might also use verbs like:

• melekat = to adhere / be attached
• berkumpul = to accumulate / gather (slightly different meaning)
• terdapat = to be found / be present (more formal, less physical)

But menempel is a very natural choice because it clearly expresses the idea of something sticking to an area.

Yes, it is natural and understandable.

It sounds like a health, dental, or educational sentence. It is straightforward and idiomatic.

A slightly more explicit or polished version might be:

• Plak dan karang gigi menempel di sekitar tambalan gigi.

But the original sentence is already good Indonesian.

A simple pronunciation guide:

Plak dan karang gigi menempel di sekitar tambalan.

Approximate pronunciation: plak dan kah-rang gee-gee muh-nem-pel dee suh-kee-tar tam-bah-lan

A few tips:

• g in gigi is always a hard g, like in go
• e in menempel is the Indonesian e sound, often like a schwa in unstressed syllables
• di is pronounced dee
• stress in Indonesian is usually fairly even, not as strong as in English

Di sekitar tambalan most directly means around the filling, so it emphasizes the surrounding area.

It can suggest that the buildup is:

• on the edges of the filling
• near the filling
• in the area surrounding it

If someone wanted to say clearly on the filling itself, they might say:

• pada tambalan
• di tambalan

So di sekitar tambalan focuses more on the area around it than exactly on it.
