Az őrlőfog kezelése sikeres.

In Hungarian, the verb to be is usually left out in the present tense when the subject is third person singular or plural.

So:

• Az őrlőfog kezelése sikeres. = The treatment of the molar is successful.

Literally, it is more like:

• The molar’s treatment successful.

But this is completely normal Hungarian.

Compare:

• Én fáradt vagyok. = I am tired.
• Te fáradt vagy. = You are tired.
• Ő fáradt. = He/she is tired.

So in your sentence, leaving out is is standard Hungarian grammar.

Az is the definite article, meaning the.

Hungarian has two forms of the definite article:

• a
• az

Which one is used depends on the sound that follows:

• a before a consonant sound
• az before a vowel sound

Here the next word is őrlőfog, which begins with the vowel ő, so Hungarian uses:

• az őrlőfog kezelése

Compare:

• a fog = the tooth
• az őrlőfog = the molar

This is similar to the difference between a and an in English, although the Hungarian rule applies to the definite article.

Őrlőfog means molar.

It is made up of parts that are quite transparent once you know them:

• őröl = to grind
• fog = tooth

So őrlőfog is literally something like grinding tooth, which makes sense for a molar.

This is a useful example of how Hungarian often builds words very logically.

Kezelése means its treatment or the treatment of it.

It comes from:

• kezel = to treat
• kezelés = treatment
• kezelése = his/her/its treatment

The ending -e here is a third-person singular possessive suffix.

So:

• kezelés = treatment
• kezelése = its treatment / his treatment / her treatment

In this sentence, the thing being treated is az őrlőfog (the molar), so:

• az őrlőfog kezelése = the treatment of the molar = literally the molar’s treatment

This kind of possessive structure is very common in Hungarian.

Hungarian usually expresses of relationships with a possessive structure, not with a separate word like English of.

So instead of saying:

• the treatment of the molar

Hungarian naturally says something closer to:

• the molar’s treatment

That is why you get:

• őrlőfog kezelése

Structure:

• őrlőfog = molar
• kezelése = its treatment

So the whole phrase is literally:

• molar treatment-of-it

This is one of the most important structural differences between English and Hungarian.

Good question. In Hungarian, the possessor can appear in more than one way.

In a neutral possessive phrase, the possessor often appears without an ending, while the possessed noun gets the possessive suffix:

• az őrlőfog kezelése = the treatment of the molar

Here:

• őrlőfog = possessor
• kezelése = possessed noun with possessive suffix

Hungarian can also use a more explicit possessor form with -nak / -nek:

• az őrlőfognak a kezelése

This also means the treatment of the molar, but it is a bit more explicit or marked.

So the version in your sentence is the normal, natural compact structure.

Because Hungarian structures this differently.

English says:

• the treatment of the molar

Hungarian says something more like:

• the molar treatment-its

So the article az belongs to the whole noun phrase:

• Az őrlőfog kezelése

Hungarian does not need to repeat the article in the same way English does.

You may also see:

• az őrlőfognak a kezelése

In that version, there are two articles/elements marking the structure more clearly, but the shorter version in your sentence is very common.

Sikeres is an adjective meaning successful.

So the sentence structure is:

• Az őrlőfog kezelése = the treatment of the molar
• sikeres = successful

Together:

• Az őrlőfog kezelése sikeres. = The treatment of the molar is successful.

Because Hungarian omits is here, the adjective comes directly after the subject phrase.

Yes, Hungarian word order is often more flexible than English, but different orders can change the focus or emphasis.

The neutral order here is:

• Az őrlőfog kezelése sikeres.

This presents the whole subject first, then the comment about it.

If you changed the order, the emphasis might change, and some versions could sound less neutral in ordinary usage.

For a learner, the safest understanding is:

• subject: Az őrlőfog kezelése
• predicate adjective: sikeres

So this sentence is a straightforward neutral statement.

The letter ő is a long Hungarian vowel that does not exist in standard English.

A good approximation is:

• like the vowel in French peu
• or German ö in schön, but held longer

In őrlőfog, both ő sounds are long:

• őr-lő-fog

A rough learner-friendly approximation might be something like:

• ur-luh-fog, but with rounded lips

Important point:

• o and ő are different vowels in Hungarian
• vowel length and quality both matter

In Hungarian, sz is pronounced like English s in see.

This often surprises learners, because:

• sz = s
• s = sh

So:

• kezelése has a normal s sound where sz appears
• sikeres begins with sh, because it starts with plain s

So approximately:

• kezelése → keh-zeh-lay-sheh (very roughly)
• sikeres → shee-keh-resh

This spelling system is very consistent once you get used to it.

It is singular.

• kezelés = treatment
• kezelése = its treatment

If it were plural, the form would be different.

So the sentence talks about one treatment or the treatment as a single process/event, not multiple treatments.

That matches the English meaning The treatment of the molar is successful, not The treatments of the molar are successful.

Yes. In fact, that is very close to the literal Hungarian structure.

Hungarian:

• Az őrlőfog kezelése sikeres.

Literal structure:

• The molar’s treatment successful.

Natural English:

• The treatment of the molar is successful.
• The molar’s treatment is successful.

In most contexts, English prefers the treatment of the molar, but Hungarian naturally uses the possessive pattern. So understanding the literal structure can help you read similar Hungarian phrases more easily.
