Jeg bløder fra tandkødet.

Bløder is the present tense form of the verb at bløde (to bleed).

A very common Danish pattern is:

• infinitive: at bløde
• present tense: bløder
• past tense: blødte
• past participle: blødt

So Jeg bløder means I am bleeding or I bleed, depending on context. Danish does not usually need a separate form like English am bleeding here.

Here fra means from and shows the source of the bleeding.

So Jeg bløder fra tandkødet is literally something like I bleed from the gums/gum tissue.

In Danish, fra is very natural when you want to say where something is coming from:

• Hun bløder fra næsen = She is bleeding from the nose
• Han bløder fra hånden = He is bleeding from the hand

Because -et is the definite ending of this noun.

Tandkød is a neuter noun (et tandkød), so the definite singular form is tandkødet:

• et tandkød = a gum / gum tissue
• tandkødet = the gum / the gums / the gum tissue

In Danish, the definite article is usually attached to the end of the noun instead of being a separate word.

Danish often uses the definite form where English would use a possessive like my, especially for body parts when it is already obvious whose body it is.

So Danish prefers things like:

• Jeg har ondt i hovedet = literally I have pain in the head = My head hurts
• Jeg bløder fra tandkødet = literally I’m bleeding from the gum tissue = natural English My gums are bleeding / I’m bleeding from the gums

This is a very common pattern and is worth getting used to.

Tandkød is usually treated as a mass noun or collective noun, like gum tissue.

So even though English often says gums, Danish can use the singular collective noun tandkød:

• tandkød = gum tissue / gums
• tandkødet = the gum tissue / the gums

This is normal Danish and does not sound strange.

Yes, absolutely.

Mine gummer bløder means My gums are bleeding and is also very natural.

There is a slight difference in style:

• Jeg bløder fra tandkødet focuses on me and the fact that bleeding is happening.
• Mine gummer bløder focuses directly on the gums.

Also:

• tandkød is a bit more anatomical or formal
• gummer is often a bit more everyday and directly matches English gums

Both are useful.

The tricky part is the vowel ø.

A rough guide:

• bløder sounds approximately like BLUR-thur with a Danish-style vowel, but that is only a rough hint.
• The ø is a rounded front vowel that English does not really have.
• The d in bløder is usually a soft d, not a hard English d.

A learner-friendly approximation might be:

• bløder ≈ BLUR-er with rounded lips

The exact pronunciation depends a bit on accent, but the main challenge is the ø and the soft d.

A few useful points:

• tand sounds roughly like tan with a soft Danish d at the end
• kød contains the same ø sound
• the final -et in tandkødet is usually not strongly pronounced like English et

A rough approximation is:

• tandkødet ≈ TAN-kur-theth or TAN-kø-thəth

But again, this is only approximate. The important things are:

• the ø sound
• the soft Danish d
• the fact that the definite ending -et is attached to the noun

No, this is the normal word order for a simple Danish statement:

• Jeg = subject
• bløder = verb
• fra tandkødet = prepositional phrase

So the structure is:

Subject + verb + other information

This is the standard pattern in main clauses:

• Jeg spiser nu
• Han arbejder hjemme
• Jeg bløder fra tandkødet

Usually fra tandkødet is better if you mean that the blood is coming from the gums.

Fra emphasizes the source.

If you say i tandkødet, that sounds more like in the gums, which is less natural for this idea. Danish normally uses fra with bleeding when naming the body part that the blood comes from.

So:

• Jeg bløder fra tandkødet = natural
• Jeg bløder i tandkødet = less natural for this meaning

Yes, it is understandable and natural.

At a dentist, you might also hear or say:

• Mit tandkød bløder = My gums are bleeding
• Mine gummer bløder = My gums are bleeding
• Jeg bløder fra tandkødet, når jeg børster tænder = My gums bleed when I brush my teeth
• Mit tandkød bløder let = My gums bleed easily

So your sentence is perfectly usable, especially when you want to describe the symptom clearly.
