I had a crown placed today on my lower molar. When I bite down there is bloackge on the top molar directly above tooth with a crown. I can see what looks like porcelain glob attached to that top molar. I can't bite down, chew or even bring my teeth togerher. Is this normal? Is this to prevent me from biting down on the crown? I'm not sure I can handle this for 2 weeks til my permanent crown is done!!
