Recent crown doesn't fit well against next tooth and food is getting stuck constantly.

I recently had a crown placed on one of my upper right teeth. Apparently it wasn't fit correctly so the spacing between the next tooth is too much now and I get food stuck in it constantly and my gum is so sore that it even throbs. I went back and the dentist said that since my next tooth also needs a crown that he will just make the next one bigger to fit tighter against the first crown. Is that an appropriate fix or should the first one be remade?
