Give me your teeth!

Your teeth have just fallen out. You look terrible. What do you do? Easy! You go to a dentist and get some false teeth. You are lucky somebody has invented them. Do you know what people did in the seventeenth century? There were two choices:

They found a dead man and borrowed his teeth, or they looked for a walrus and used the ivory from its tusks to make some teeth.  It is not very nice, is it? But that´s what happened before the invention of false teeth.

Use the present perfect simple, NOT the past simple, to talk about things that happened a short time before now but that are still important now.

   My teeth have just fallen out!

   (It is important now. I have nor got any teeth)

Use the past simple to talk about things that are finished.

   My baby teeth fell out when I was three.

   (This is a fact about the past: It is nor important now.)

Present perfect simple 

This is the present perfect simple.

   

   This is terrible! I have just lost all my teeth

   Nobody has invented false noses yet, have they?

   Have you already read that book?

You can use these words with the present perfect simple

   Just, already, not yet, yet

Oh no! My teeth have just fallen out.

I am only twenty and I have already lost my teeth!

Inventors have not made flying cars yet

Has anybody invented unbreakable glasses yet?

Past simple

This is the past simple 

   My teeth fell out when I was five.

   False teeth did not exist in 1675

   Did you see a walrus at the zoo yesterday?
