Hello, in january 25th, the dentist repaired all of my teeth, and said no more teeth left to repair as they are were in good condition, however, like in this week, all the teeth that been filled with composite filled, are very senstive to everything?

If the teeth restored had deep cavities, close to the nerves than sensitivity is expected. Ask if a cavity liner[base] was placed. Composites will give some sensitivity but they usually go away, unless the cavity was so deep that a root canal is necessary.

Composite is a restorative material that is prone to complications if anything is not perfectly done during placement. If this is the cause then replacement may be needed and possibly a different professional would be an idea. Other causes could be acid reflux or damage from acidic drinks.

Fillings are surgical procedures. Your Dentist had to remove the parts of the teeth that were infected and replace the surgeries tooth tissue with an artificial material. The deeper the cavity, the more risk of damage to the nerve. If you are having discomfort, return to the Dentist. (S)He is responsible for your post-surgical care.
