Braces-First Adjustment & New Wires

Question

Question:

What is the point of new wires? Everyone keeps saying thicker wire. What does that thicker wire do? Does it carry a different force? I thought the ligature bands is what gives the wire the force? I'm kind of confused!

Also, do you get a thicker wire everytime? Is this thicker wire visibly thicker and noticable?

Does the thicker wire cause a drastic diff in pain?

Thank you for your help and answering my question about my previous question.

Answer 1

No, you can't physically see the difference in the thicker wire, but you can feel the difference when they first put it in.  It will feel kind of heavier and tighter.  It won't last long though...maybe 2 or 3 days and you'll get used to it.  No, you won't get a thicker wire at every visit.  

Answer 2

The wires are memory wires.  So over time they move your teeth back to the original "U" shape the wire was in.  The thicker wire corrects your teeth more.  You won't always get a thicker wire, but you won't be able to tell just by looking.  A thicker wire will hurt more for about three days but then you will get used to it, just like the previous wire they put in.
