Why are my front teeth crowns clicking?

I had my four front teeth crowned two weeks ago. After the permanent crowns were fitted, everything was great for the first week, but now I constantly feel a clicking or slight back and forth movement when my tongue touches my teeth. The crowns seem to be well fitted but I am not sure what the movement is an indication of. I also feel some light tension, similar to a feeling of having braces taken off. Are the crowns still settling in?
