चेहरा धोने के बाद मैं दाँत साफ करती हूँ।

Because के बाद requires the verb to appear in the oblique infinitive form.

• Basic infinitive: धोना = to wash
• Before postpositions like के बाद = after, it changes to धोने

So:

• धोना = to wash
• धोने के बाद = after washing

This is a very common pattern in Hindi:

• खाने के बाद = after eating
• सोने से पहले = before sleeping
• पढ़ने के बाद = after studying

के बाद means after.

In this sentence:

• चेहरा धोने के बाद = after washing the face / after washing my face

Literally, the structure is:

• धोने = washing
• के बाद = after

So Hindi often says something closer to washing after rather than using a separate subordinating word like English after I wash.

Because the after washing the face part is an introductory time phrase. Hindi often puts that first.

So the sentence is structured like:

• चेहरा धोने के बाद = after washing my face
• मैं = I
• दाँत साफ करती हूँ = clean my teeth / brush my teeth

This word order is very natural in Hindi. It highlights the sequence of actions.

You could think of it as:

• After washing my face, I brush my teeth.

Hindi often leaves out possessives like my when they are obvious from context, especially with body parts.

So:

• चेहरा धोने के बाद naturally means after washing my face
• दाँत साफ करती हूँ naturally means I clean my teeth

If needed, Hindi can include the possessive:

• मेरा चेहरा
• मेरे dाँत

But in everyday speech, that often sounds unnecessary when the subject is already I.

Because दाँत here is the direct object and is not followed by a postposition.

Hindi nouns usually take the direct form when they are plain objects:

• मैं दाँत साफ करती हूँ। = I clean my teeth.

The oblique form दाँतों would be used before a postposition, for example:

• दाँतों में = in the teeth
• दाँतों पर = on the teeth

So in this sentence, दाँत is correct.

Because दाँत साफ करना is a very common Hindi expression meaning to clean the teeth, which in natural English is often to brush one’s teeth.

Here:

• साफ = clean
• करती हूँ = do / make / perform

Together:

• दाँत साफ करती हूँ = I clean my teeth / I brush my teeth

Hindi often uses combinations like this:

• काम करना = to do work
• तैयार करना = to prepare
• साफ करना = to clean

So साफ करना is the normal verb phrase for to clean.

Because the speaker is feminine.

In the present habitual:

• करता हूँ = I do (said by a male speaker)
• करती हूँ = I do (said by a female speaker)

So this sentence is being said by a woman or girl:

• मैं दाँत साफ करती हूँ।

If a man were saying it, it would be:

• चेहरा धोने के बाद मैं दाँत साफ करता हूँ।

It is the present habitual.

So मैं दाँत साफ करती हूँ usually means something like:

• I clean my teeth
• I brush my teeth
• I do this as part of my routine

In a sentence like this, it often describes a habitual sequence:

• After washing my face, I brush my teeth.

If you wanted to emphasize that it is happening right now, Hindi would more likely use a progressive form, such as कर रही हूँ.

In this sentence, it is understood as after I wash my face because the main subject is मैं.

Hindi often leaves that subject unspoken in non-finite clauses like this one. So the understood subject of धोने is the same as the subject of the main clause unless context suggests otherwise.

So learners should read it as:

• After washing my face, I brush my teeth.

not usually

• After someone washes a face, I brush my teeth.

Hindi does not need a separate word for then here, because the sequence is already clear from के बाद.

• चेहरा धोने के after already tells you that one action happens first.
• The next clause gives the next action.

English sometimes says:

• After washing my face, then I brush my teeth.

But Hindi normally does not need an extra equivalent of then in this sentence.

Both words exist, but they are not exactly the same.

• चेहरा = face
• मुँह = mouth / face, depending on context

In standard, careful Hindi:

• चेहरा धोना = wash the face
• मुँह धोना can also be said, but it often feels more like washing the mouth/face area and can vary by context and region.

So चेहरा धोने के बाद is a clear and natural choice for after washing my face.

Yes. That is the same meaning, just with a different English word order.

Hindi:

• चेहरा धोने के बाद मैं दाँत साफ करती हूँ।

Natural English translations include:

• After washing my face, I brush my teeth.
• I brush my teeth after washing my face.

Both are fine.

Usually yes, in everyday context.

Literally it means to clean the teeth, but in normal situations English speakers would often translate it as to brush my teeth.

If you want to be very explicit about using a toothbrush, Hindi can also say things like:

• ब्रश करना = to brush
• दाँत ब्रश करना = to brush one’s teeth

But दाँत साफ करना is extremely common and natural.

Yes, but the original order is very natural.

Original:

• चेहरा धोने के बाद मैं दाँत साफ करती हूँ।

You could also say:

• मैं चेहरा धोने के बाद दाँत साफ करती हूँ।

Both are understandable. The original version sounds especially natural if you want to emphasize the sequence: first face, then teeth.

Hindi word order is somewhat flexible, but the default tendency is still to keep the verb near the end and let time phrases appear early in the sentence.
