If a tooth has taken a hit it might have come somewhat loose. The ligaments holding the tooth can have been stretched but can firm up after a while, so the tooth may need to be fixated, to give it rest. This can be done with a metal wire attached to the neighboor teeth(s) and depending on the occlusion the wire can be placed either on the front or the back of the teeth. After some time the wire can be removed, depending on how big a hit the tooth had taken.
Capping teeth (ceramic or metal/gold) involves taking impressions of the teeth, so a dental lab can make the crowns to fit 100% correct. This is a process that usually takes several days and not something that is made on a single visit. It's not just large amalgam fillings in the lower teeth?
Just trying to get a better understanding about what treatment has been made.
If someone comes in with a chipped tooth, the first thing I would do would be to take an x-ray, so that sounds strange.
