У меня чувствительные зубы, поэтому я не люблю холодную воду.

Russian usually expresses possession with the pattern у + genitive + есть / implied “there is” rather than a verb like to have.

So У меня чувствительные зубы literally feels more like:

• At me, there are sensitive teeth

In natural English, of course, that means I have sensitive teeth.

A few notes:

• у меня = at me / I have
• In the present tense, есть is often omitted, so У меня чувствительные зубы is completely normal.
• Я имею... does exist, but it is much less common for everyday possession and often sounds formal, legal, or unnatural in conversation.

Меня is in the genitive case because the preposition у requires the genitive when it means at/by someone in possession expressions.

Compare:

• я = I
• меня = me / of me (genitive form)

So:

• у меня = at me / I have
• у тебя = at you / you have
• у него = at him / he has

This is one of the most common Russian patterns, so it is worth memorizing as a whole chunk: у меня, у тебя, у него, etc.

Both words are in the nominative plural.

• зубы is the plural of зуб (tooth)
• чувствительные is the plural adjective form of чувствительный (sensitive)

They match because Russian adjectives agree with the nouns they describe in:

• gender
• number
• case

Here:

• зубы = plural
• so the adjective must also be plural: чувствительные

That is why you get:

• чувствительные зубы = sensitive teeth

Russian normally uses the plural here, just like English often does in I have sensitive teeth.

Since the idea is about your teeth in general, plural is natural:

• У меня чувствительные зубы = I have sensitive teeth

If you were talking about one specific tooth, then you could use singular:

• У меня чувствительный зуб = I have a sensitive tooth

So the plural in your sentence means the sensitivity is a general condition, not just one tooth.

It can mean both, depending on context.

In this sentence:

• чувствительные зубы clearly means physically sensitive teeth

But чувствительный can also describe a person as sensitive in an emotional or psychological sense.

For example:

• чувствительный человек = a sensitive person

So the word is broad, and context tells you which kind of sensitivity is meant.

Поэтому means therefore, so, that’s why, or for that reason.

In this sentence:

• У меня чувствительные зубы, поэтому я не люблю холодную воду.
• I have sensitive teeth, so I don’t like cold water.

It introduces the result or consequence of the first part.

A good way to feel it is:

• first fact: I have sensitive teeth
• consequence: therefore / so I don’t like cold water

Russian usually puts a comma before поэтому when it connects two clauses like this.

Your sentence has two parts:

1. У меня чувствительные зубы
2. поэтому я не люблю холодную воду

The comma marks the connection between the cause and the result.

This is very standard punctuation in Russian.

Люблю is the 1st person singular present tense of любить:

• я люблю = I love / I like
• я не люблю = I do not like

Russian often uses любить with не to mean not like, especially for general preferences or dislikes.

So here:

• я не люблю холодную воду = I don’t like cold water

This means a general, habitual dislike, not just one specific moment.

Both can work, but they are used differently.

Your sentence uses:

• я не люблю холодную воду = I don’t like cold water

This is a straightforward statement about personal preference.

If you used нравиться, the structure would change:

• мне не нравится холодная вода

Literally, that is more like:

• cold water is not pleasing to me

So:

• не люблю = I don’t like / I dislike
• мне не нравится = it doesn’t appeal to me / I don’t like it

Both are natural, but не люблю can sound a bit more direct and general as a preference.

Because воду is the direct object of люблю, it must be in the accusative case.

Base form:

• холодная вода = cold water

After люблю:

• люблю холодную воду = I like cold water
• не люблю холодную воду = I don’t like cold water

Both the noun and adjective change:

• вода → воду
• холодная → холодную

This is because вода is feminine singular, and the adjective must agree with it.

Yes:

• холодную = cold
  
  • adjective
  • feminine singular accusative
• воду = water
  
  • noun
  • feminine singular accusative

Dictionary forms are:

• холодный = cold
• вода = water

Because вода is feminine singular and is the direct object, the phrase becomes:

• холодную воду

The given word order is the most neutral and natural:

• У меня чувствительные зубы, поэтому я не люблю холодную воду.

But Russian word order is more flexible than English, because case endings show the grammatical roles.

You might also hear variations for emphasis, for example:

• Поэтому я не люблю холодную воду: у меня чувствительные зубы.
• Холодную воду я не люблю, потому что у меня чувствительные зубы.

However, the original version is the best one to learn first because it sounds natural and clear.

Yes, but the sentence structure changes because the logic changes direction.

Your sentence with поэтому is:

• I have sensitive teeth, therefore I don’t like cold water.

With потому что, you would usually say:

• Я не люблю холодную воду, потому что у меня чувствительные зубы.
• I don’t like cold water because I have sensitive teeth.

So:

• поэтому = therefore / so → introduces the result
• потому что = because → introduces the reason

Both are natural; they just organize the information differently.

Yes, the main stress is:

• У меня́ чувстви́тельные зу́бы, поэ́тому я не люблю́ холо́дную во́ду.

A few useful stress points:

• меня́
• чувстви́тельные
• зу́бы
• поэ́тому
• люблю́
• холо́дную
• во́ду

One especially useful note: in поэтому, the stress is on э:

• поэ́тому

And in fast speech, Russian vowels in unstressed syllables are reduced, so listening practice helps a lot.

Russian does not have articles like English a, an, and the.

So:

• зубы can mean teeth or the teeth, depending on context
• воду can mean water, the water, or sometimes some water, depending on context

In your sentence, English naturally uses no article before water and no article before sensitive teeth in the usual translation:

• I have sensitive teeth, so I don’t like cold water.

Russian leaves article-type meaning to context rather than separate words.
