What do i do if my blue elastic spacer popped but it's still in there it did not fall out. Is it still good ?

Braces involve a process of widening your smile and straightening teeth. It needs to happen slowly to not damage the roots of your teeth. The bite will change with every wire you have placed. Call the drs office and go in to make sure the cement is ok and to answer questions you have after the ...

The teeth support your lips and play a big role in your profile. If you feel your upper lip sticks out, it may be your lower jaw and lip on the lower making it look this way. I would see see an orthodontist to discuss your concerns. 

Unfortunately new retainers wont have the ability to move your teeth. Retainers only hold the teeth in position. However with clear aligner systems like the invisalign you can move the teeth relatively fast.All the best,
