I have braces on and when I bite down my back teeth hurt on my right side. Why????????

When I got my braces I had two baby teeth still in. I lost the one on my left side first, and about 7 days later, I lost the one on my right side. A few days after Iost my last baby tooth, it hurt whenever I bit down and my teeth touched on that side. Sometimes, it even hurt my front teeth. I think I noticed my back teeth shifting to make room for the tooth, but they aren't lined up anymore because of it! Is this something to worry about??????? I am going to the ortho in 9 days for a tightening and will he notice a problem??? P.S When I wake up in the morning it doesn't hurt, but as the day goes on and I bite down more it hurts.

dont worry..the same thing happened to me....braces are a tough thing...they are realli painful...this is ebcause your teeth have nerves....afer every tightening you have of your braces, it might even take you a week to get used to them!!
no worries! its all natural.
whenever i get my braces tightened, it also hurts when i bite down..
your teeth may be shifting back because maybe your ortho is trying to expand your mouth and no worries..at the end your teeth will be perfect!
