I Have 2 Back Teeth (one On Each Side, Upper

I have 2 back teeth (one on each side, upper mouth) and the problem with it is those two are behind my normal set because my jaw is not wide for all of them to fit in one line. I plan to pull the two and I was wondering if the gap, which is very minor would cause any problems, such as other teeth moving around. I have already seen an orthodontist and they have given an estimate on the braces, but my parents and I don't have that type of money. So my question again is: will the minor gap between the teeth, when I pull them, cause the others to shift or move around? If so, would teeth gap bands be effective in this case to close it?
