Her sabah dişlerimi dikkatlice fırçalıyorum, böylece sağlıklı kalıyorlar.

Her means every/each, and sabah means morning. Together, her sabah means every morning.

It works as a time expression, so Turkish does not need a preposition like in or on here.

Because dişlerimi is the direct object of the verb fırçalıyorum.

Here is the breakdown:

• diş = tooth
• dişler = teeth
• dişlerim = my teeth
• dişlerimi = my teeth (as a definite object)

The final -i is the accusative ending, which is commonly used when the object is specific/definite. Since you are talking about my teeth, Turkish marks that object.

It is made from several parts:

• diş = tooth
• -ler = plural
• -im = my
• -i = accusative

So:

diş + ler + im + i = dişlerimi

The order is important in Turkish: noun + plural + possessive + case

Turkish often drops subject pronouns when the verb already shows the person clearly.

In fırçalıyorum, the ending -um tells you the subject is I.

So (Ben) her sabah dişlerimi dikkatlice fırçalıyorum is possible, but ben is unnecessary unless you want extra emphasis.

Fırçalıyorum is the present continuous form.

Breakdown:

• fırçala- = brush
• -ıyor- = present continuous
• -um = I

So it literally means I am brushing, but in Turkish this form is also very commonly used for habitual actions, especially when there is a time phrase like her sabah.

So even though English says I brush my teeth every morning, Turkish naturally says fırçalıyorum here.

Yes, you could.

Fırçalarım is the aorist form, which is also used for habits and general routines. So:

• Her sabah dişlerimi fırçalıyorum = very natural, common in everyday speech
• Her sabah dişlerimi fırçalarım = also possible, a bit more like I brush my teeth every morning / I do that regularly

With her sabah, both can work. Learners should know that Turkish often uses -yor for repeated daily actions too.

Dikkatlice means carefully.

It comes from dikkatli meaning careful, plus -ce/-ca, which can turn some adjectives into adverbs.

So:

• dikkatli = careful
• dikkatlice = carefully

It tells us how the brushing is done.

Because Turkish usually puts adverbs before the verb they modify.

So:

• dişlerimi dikkatlice fırçalıyorum = I brush my teeth carefully

That said, Turkish word order is fairly flexible, and you may hear variations depending on emphasis. But placing dikkatlice before fırçalıyorum is very normal.

Böylece means something like thus, so, in this way, or as a result.

In this sentence, it links the two ideas:

• I brush my teeth carefully every morning
• böylece they stay healthy

So it introduces the result of the first action.

Literally, it means they stay healthy or they remain healthy.

Breakdown:

• sağlıklı = healthy
• kalmak = to stay, remain
• kalıyorlar = they are staying / they stay

Turkish often uses adjective + kalmak to mean remain in a state:

• mutlu kalmak = stay happy
• açık kalmak = stay open
• sağlıklı kalmak = stay healthy

The subject is understood from the first part of the sentence.

In the first clause, you mention dişlerimi. In the second clause, Turkish does not need to repeat dişlerim if the meaning is already clear. So kalıyorlar refers to the teeth.

This kind of omission is very common in Turkish.

Because the understood subject is dişlerim = my teeth, which is plural.

So the sentence treats the second clause as:

(Dişlerim) böylece sağlıklı kalıyorlar.

However, there is an important nuance: with non-human plural subjects, Turkish often uses a singular verb as well. So many speakers would also naturally say:

Her sabah dişlerimi dikkatlice fırçalıyorum, böylece sağlıklı kalıyor.

That may sound more idiomatic to many native speakers. The version with kalıyorlar is still understandable and makes the plural very explicit.

Not completely. Turkish word order is flexible, but the most neutral pattern usually puts the verb near the end.

This sentence follows a very natural structure:

• Her sabah = time
• dişlerimi = object
• dikkatlice = manner
• fırçalıyorum = verb

So it is close to: Every morning + my teeth + carefully + I brush

You can move parts around for emphasis, but the given order is clear and natural.
