Dokter gigi memeriksa sariawan, air liur, dan gigi palsu saya.

Yes. Dokter gigi literally means tooth doctor, and it is the normal Indonesian way to say dentist.

This is a very common pattern in Indonesian: a general noun is followed by another noun that specifies what kind of thing it is.

• dokter = doctor
• gigi = tooth / teeth

So dokter gigi = a doctor for teeth = dentist.

Indonesian usually does not use articles like a, an, or the.

So dokter gigi can mean:

• a dentist
• the dentist
• sometimes just dentist in a general sense

The exact meaning depends on context. If you want to make a dentist more explicit, you could say seorang dokter gigi, but it is often unnecessary.

Periksa is the base word meaning check or examine.
Memeriksa is the active verb form built from that base.

The prefix meN- often makes an active verb in Indonesian. So:

• periksa = examine / inspection / check
• memeriksa = to examine, to inspect, to check

In this sentence, memeriksa is the normal verb form for examines / examined / is examining, depending on context.

Yes. The sentence follows the standard Indonesian pattern:

• Dokter gigi = subject
• memeriksa = verb
• sariawan, air liur, dan gigi palsu saya = objects

So it is a normal Subject–Verb–Object sentence.

Yes. Saya means I / me, but when it comes after a noun, it means my.

So:

• gigi palsu saya = my dentures / my false teeth
• dokter gigi saya = my dentist

This is because Indonesian possession usually works like this:

• noun + possessor

So Indonesian says the equivalent of dentures my, not my dentures.

Grammatically, saya most directly modifies only gigi palsu.

So the most natural reading is:

• the dentist examined canker sores, saliva, and my dentures

not necessarily:

• my canker sores, my saliva, and my dentures

If you wanted to make all three clearly possessed by me, you would usually repeat it:

• Dokter gigi memeriksa sariawan saya, air liur saya, dan gigi palsu saya.

It can be either, depending on context.

Indonesian nouns usually do not have to show singular vs. plural the way English does. So gigi palsu could mean:

• false tooth
• false teeth
• dentures

In many contexts, English would translate it as dentures, but Indonesian itself often leaves number unspecified unless the context makes it clear.

Sariawan usually means a canker sore or mouth ulcer.

In everyday Indonesian, it is the common word people use for a sore inside the mouth. So in a dental or medical context, that is the likely meaning.

Air liur is the normal Indonesian expression for saliva.

Literally:

• air = water / liquid
• liur = drool / saliva

Together, air liur means saliva. Indonesian often uses combinations like this to form common nouns.

Pretty much yes. Indonesian lists work very similarly to English lists.

• commas separate the earlier items
• dan means and before the final item

So:

• sariawan, air liur, dan gigi palsu saya
• canker sores, saliva, and my dentures

That structure is completely normal.

By itself, Indonesian does not mark tense the way English usually does.

So memeriksa could mean:

• examines
• is examining
• examined
• sometimes even will examine

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

• kemarin = yesterday
• sekarang = now
• besok = tomorrow

So without extra context, the verb itself is tense-neutral.

You would move saya so it modifies dokter gigi:

• Dokter gigi saya memeriksa sariawan, air liur, dan gigi palsu.

That means My dentist examined canker sores, saliva, and dentures.

Compare:

• dokter gigi saya = my dentist
• gigi palsu saya = my dentures

So where saya is placed matters a lot.
