Are there any side effects i should be aware of after i have my braces tightened for the first time?

Yes, here is some from what I know The primary side effect of braces is pain and it can come from two directions. When the orthodontist tightens the braces during regular appointments, it adds tension to the jaw. This tightening helps the alignment of the teeth, but puts tremendous pressure on the mouth and face.This response often triggers the feeling of pain in the mouth and head. While the pulling causes your head to feel tense, the trauma to the gums leads to greater sensitivity to the mouth tissues. Chewing or biting down on hard or rough items can cause gum pain and bleeding, as the gums are already irritated.

Yes, it will feel really tight, it doesnt neccesarily hurt it just feels a little sore, but it goes away after a day or two! You'll be ok(:

Well, l think that some effective communication is, emotional barriers and lack of attention, interest distraction or irrelevance. also some physical disabilities such as hearing problems or speech difficulties.      l hope i am correct  and you good luck.
