Jeg har tandpine.

Because Danish expresses many physical conditions with have rather than be.

• Jeg har tandpine = literally I have toothache
• This is the normal Danish way to say it.

English can also say I have a toothache, so this structure is not too unusual here. But it is useful to remember that Danish often uses har for symptoms:

• Jeg har hovedpine = I have a headache
• Jeg har feber = I have a fever
• Jeg har ondt i ryggen = I have pain in my back

So har is the natural verb in this sentence.

Word by word:

• Jeg = I
• har = have
• tandpine = toothache

So the whole sentence means I have toothache or more naturally in English, I have a toothache / I have toothache.

Also notice that tandpine is a compound word:

• tand = tooth
• pine = pain / ache

So Danish often builds words by joining smaller words together.

Because tandpine is normally used as an uncountable or general condition in Danish.

English often says:

• I have a toothache

But Danish usually just says:

• Jeg har tandpine

without en or et.

This is common with illnesses and symptoms in Danish. You often do not use an article where English might use one.

It is one word: tandpine.

Danish very often writes compound nouns as a single word. English sometimes writes similar ideas as one word, two words, or with a hyphen, but Danish strongly prefers one combined form.

Examples:

• tandlæge = dentist
• hovedpine = headache
• mavepine = stomachache

So you should write tandpine, not tand pine.

The basic word order here is:

• Jeg = subject
• har = verb
• tandpine = object/complement

So it follows the common Danish main-clause pattern:

subject + verb + rest

That makes Jeg har tandpine a very standard simple sentence.

If you start with another element, Danish still keeps the finite verb in second position:

• I dag har jeg tandpine = Today I have toothache

That verb-second pattern is very important in Danish.

A rough learner-friendly guide is:

• Jeg ≈ yai or yaiy
• har ≈ ha
• tandpine ≈ tan-pi-ne with Danish vowel qualities

A few important notes:

• Jeg is often pronounced much shorter and softer than learners expect.
• har often sounds like ha in normal speech; the r is not pronounced like a strong English r.
• In tandpine, the d in tand is often not pronounced as a clear English d in connected speech.

If you want a very rough full approximation: yai ha tan-pi-nuh

But real Danish pronunciation is softer and more reduced than English spelling-based guesses suggest.

Usually, no—or at least it is not the normal everyday phrasing.

The natural Danish sentence is:

• Jeg har tandpine

Adding en sounds unusual in most ordinary contexts. Danish treats tandpine more like a condition than a countable thing here.

So if you want to sound natural, use Jeg har tandpine.

Yes, absolutely. Jeg har tandpine is a full, natural sentence.

It has:

• a subject: Jeg
• a verb: har
• the thing/condition: tandpine

It works perfectly on its own, especially when answering a question like:

• Hvordan har du det? = How are you?
• Hvad er der galt? = What’s wrong?

Yes. Once you know tandpine, you can use it in several useful patterns:

• Jeg har tandpine. = I have toothache.
• Hun har tandpine. = She has toothache.
• Har du tandpine? = Do you have toothache?
• Jeg fik tandpine i går. = I got toothache yesterday.
• Min tandpine er værre i dag. = My toothache is worse today.

This is a good example of how learning one noun can help you build many practical sentences.

You usually make it a yes/no question by putting the verb first:

• Har jeg tandpine? = Do I have toothache?
• Har du tandpine? = Do you have toothache?

So the statement:

• Jeg har tandpine.

becomes the question:

• Har jeg tandpine?

This is a very common Danish pattern: invert the subject and verb to make a yes/no question.
