Plak menempel pada gigi.

Yes. In this sentence, plak refers to dental plaque—the sticky film that builds up on teeth.

It is a loanword used in health and dental contexts. In everyday Indonesian, especially in medical or dental explanations, plak gigi means dental plaque.

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

So in this sentence, it describes plaque as being attached to the teeth.

A useful related pair is:

• menempel = to stick / be stuck / adhere
• menempelkan = to stick something onto something

For example:

• Plak menempel pada gigi. = plaque sticks to the teeth
• Dia menempelkan poster di dinding. = he/she sticks a poster on the wall

Tempel is the base word. Adding the prefix meN- makes it menempel.

This is a very common Indonesian pattern. When meN- is added to a root beginning with t, the t usually drops:

• tempel → menempel
• tulis → menulis
• tarik → menarik

So menempel is the normal derived form from tempel.

Here, pada means something like on, to, or upon, depending on the context.

In menempel pada gigi, it marks what the plaque is sticking to: the teeth.

So pada gigi means to/on the teeth.

In more natural English, you would translate the whole phrase according to the verb:

• menempel pada gigi = sticking to the teeth

Both pada and di can sometimes be translated as on or at, but they are not always interchangeable.

In this sentence, pada sounds a bit more standard or formal, and it is very common in explanatory, medical, or written language.

• Plak menempel pada gigi. = standard/formal-sounding
• Plak menempel di gigi. = also understandable and natural, a bit more everyday

So pada is a good choice here, especially in educational or health-related language.

It can be either, depending on context. Indonesian nouns usually do not change form for singular vs. plural.

So gigi can mean:

• tooth
• teeth

In this sentence, the most natural interpretation is generic teeth or the teeth.

If you needed to be very specific, Indonesian could say:

• satu gigi = one tooth
• gigi-gigi = teeth (plural), though this is not always necessary and may sound less natural in some contexts

Very often, context does the job.

Because Indonesian does not use to be the same way English does.

Also, in this sentence, menempel is already a full verb, so nothing like is is needed.

The structure is simply:

• Plak = subject
• menempel = verb
• pada gigi = prepositional phrase

So Indonesian does not need something equivalent to Plaque is sticks on teeth.
It just says Plak menempel pada gigi.

The basic order is:

Subject + Verb + Prepositional phrase

So:

• Plak = subject
• menempel = verb
• pada gigi = where/what it sticks to

This is a very common and straightforward Indonesian sentence pattern.

Yes, it is natural, especially in written explanations, health advice, or educational material.

A more casual spoken version might be:

• Plak nempel di gigi.

Here:

• nempel is a casual form of menempel
• di sounds more conversational than pada

So:

• Plak menempel pada gigi. = neutral to formal
• Plak nempel di gigi. = casual speech

A simple English-friendly approximation is:

plahk muh-NEM-pel PAH-dah GEE-gee

A few notes:

• plak = one short syllable, like plock/plahk
• menempel = meh-nem-pel, with the second syllable often sounding strongest
• pada = pah-dah
• gigi = gee-gee, with hard g sounds as in go

Indonesian pronunciation is usually quite regular, so words are generally pronounced close to how they are spelled.

It is possible to hear ke in some contexts, but it is less standard here.

• ke often suggests movement to/toward
• pada or di works better for a state of being attached

So for plaque sticks to the teeth, the best choices are:

• Plak menempel pada gigi.
• Plak menempel di gigi. (more everyday)

Using ke would sound less natural for this specific meaning.

Not exactly. Plak menempel pada gigi is a full sentence: Plaque sticks to the teeth or Plaque is attached to the teeth.

If you want a noun phrase like the plaque on the teeth, Indonesian would more likely say something like:

• plak pada gigi
• plak yang menempel pada gigi

So the original sentence is a complete statement, not just a phrase.
