fillings

I went to the dentist to ask if I can put braces and she then adviced me to fill up my teeth because I had gaps inside and before they could put braces on me I has to fill up the gaps. The dentist then put fillings on both my left teeth and the right side and now after 2 weeks of having the filling I cannot chew properly nor can I drink hot or cold water, I went back to tell her that the problemis afaffecting me but nothing was done all she did was level the filling which did not help because now both sides are painful, I only use the right side to chew because the right side hasn't gotten as bad as the left one! I never had problmes with my teeth or chewing until I went to Go get this fillings, now I'm always in pain
