A dentista pediu que eu abrisse bem a boca e não mexesse o queixo.

Questions & Answers about A dentista pediu que eu abrisse bem a boca e não mexesse o queixo.

Why is it a dentista and not o dentista?

Because the sentence is referring to a female dentist.

In Brazilian Portuguese, many profession words can be used with o for a man and a for a woman:

  • o dentista = the male dentist
  • a dentista = the female dentist

The noun dentista itself does not change form here; the article shows the gender.

Why does the sentence use pediu que?

Pedir que is a very common structure meaning to ask/request that...

So:

  • A dentista pediu = The dentist asked/requested
  • que eu abrisse... = that I open...

In Portuguese, after verbs like pedir, querer, esperar, and similar verbs of request, desire, or expectation, you very often get que + subjunctive.

Why are abrisse and mexesse used instead of abri or abria?

Because after pediu que, Portuguese requires the subjunctive, not the indicative.

Here, abrisse and mexesse are in the imperfect subjunctive.

Why imperfect subjunctive?

Because the main verb is in the past:

  • A dentista pediu... = The dentist asked...
  • so the requested action is expressed with abrisse / mexesse

This is a very common pattern:

  • Ela pede que eu abra a boca. = She asks that I open my mouth.
  • Ela pediu que eu abrisse a boca. = She asked that I open my mouth.

So the tense shifts like this:

Could you also say A dentista pediu para eu abrir...?

Yes. In everyday Brazilian Portuguese, pediu para eu abrir a boca is very common and natural.

So these are both possible:

  • A dentista pediu que eu abrisse...
  • A dentista pediu para eu abrir...

The version with que + subjunctive often sounds a bit more formal or more traditionally grammatical, while para + infinitive is very common in speech.

Why is eu included in que eu abrisse?

Because Portuguese often includes the subject pronoun when it helps make the sentence clear.

Here it matters because the person asking and the person doing the action are different:

  • A dentista = the one who asked
  • eu = the one who should open the mouth

So que eu abrisse clearly means that I should open.

If you removed eu, the sentence would sound incomplete or unclear here.

Why is there no second que eu before não mexesse o queixo?

Because the subject is still the same: eu.

So after e, Portuguese can simply continue with another verb in the same form:

  • A dentista pediu que eu abrisse bem a boca e não mexesse o queixo.

This means:

  • she asked that I open my mouth wide
  • and that I not move my chin

Portuguese often avoids repeating words when the subject is already clear.

A more expanded version would be:

  • A dentista pediu que eu abrisse bem a boca e que eu não mexesse o queixo.

That is grammatically fine too, but less economical.

What does bem mean in abrisse bem a boca?

Here bem does not mean well in the usual sense. It works more like an intensifier.

Abrir bem a boca means:

  • open your mouth wide
  • open your mouth really well

So bem emphasizes that the mouth should be opened fully.

This is a very common use of bem in Brazilian Portuguese.

Why does Portuguese say a boca and o queixo instead of minha boca and meu queixo?

Portuguese often uses the definite article with body parts when it is already obvious whose body part is meant.

So instead of saying:

  • minha boca
  • meu queixo

Portuguese naturally says:

  • a boca
  • o queixo

Because from the context, it is clear that the dentist is talking about your mouth and your chin.

This is very common in Portuguese:

  • Lave as mãos. = Wash your hands.
  • Feche os olhos. = Close your eyes.
  • Levante a cabeça. = Raise your head.

English usually prefers the possessive; Portuguese often prefers the article.

What exactly does mexer o queixo mean?

Here mexer o queixo means to move the chin/jaw area.

The verb mexer has several meanings depending on context, including:

  • to move
  • to fidget
  • to touch or tamper with
  • to stir

In this sentence, it means move.

So não mexesse o queixo means the dentist wanted the person to keep that part still.

Why is it mexesse o queixo and not mexesse no queixo?

Because mexer can be used in different ways.

Two common patterns are:

  • mexer em/no/algo = to touch, tamper with, fiddle with something
  • mexer algo / uma parte do corpo = to move something, especially a body part in some contexts

So:

  • não mexa no aparelho = don’t touch/tamper with the device
  • não mexa o braço = don’t move your arm

In this sentence, the meaning is move, so mexesse o queixo is natural.

How are abrisse and mexesse formed?

They are both imperfect subjunctive forms.

A useful way to form this tense is from the third-person plural preterite:

  • abrirabriram → remove -ramabri-abrisse
  • mexermexeram → remove -rammexe-mexesse

Full forms:

For abrir:

  • eu abrisse
  • você/ele/ela abrisse
  • nós abríssemos
  • vocês/eles/elas abrissem

For mexer:

  • eu mexesse
  • você/ele/ela mexesse
  • nós mexêssemos
  • vocês/eles/elas mexessem

This tense is extremely common after past-tense verbs like pediu, queria, esperava, and so on.

Is this sentence formal, natural, or both?

It is natural and correct, but it sounds a little more structured or formal than casual everyday speech.

A very conversational Brazilian Portuguese version might be:

  • A dentista pediu para eu abrir bem a boca e não mexer o queixo.

The original version:

  • A dentista pediu que eu abrisse bem a boca e não mexesse o queixo.

is also perfectly natural, especially in writing or in more careful speech.
