Did you like your temporaries? It is always best to make changes in the temporaries and then have the laboratory make the permanent ones match the size, shape and color. Then you need to approve all of those things at the try-in before they are bonded into place
Zirconia crowns are no more translucent than other porcelain fused to metal crowns. All these types of crowns stop any light from getting into your tooth and showing down the root. Since the tooth was already dark, this just makes it look darker. It is possible to help make the root of a dark tooth look lighter and place an all porcelain crown like E-max. It is not real easy, but is possible.Good Luck
Your two front teeth and your canine, or cuspids, the teeth on the corner of your smile, are about the same length. You have some very short lateral incisors, the teeth in between. I would much rather see you lengthen those two teeth, than shorten the others. This could be done with either porcelain or composite veneers. Maybe even a combination of a little cosmetic reshaping of the long teeth along with the two veneers would help.Good Luck
Any situation like this causes an area for bacteria to hide in. One of two things will ultimately happen in this area. The bacteria will either cause an inflammation that will cause some bone loss or the bacteria will be able to start a cavity. These things will not necessarily happen immediately, but over the long term one of these things will surely happen. Is there any possibility of your Dentist trimming away the excess crown and/or cement? If it is in between your teeth it may not be possible.Good Luck
You are approaching a time when changes will certainly begin to take place if something is not done. If significant movement of the adjacent teeth has not occurred yet, you can do something about it. I would suggest finding a Dentist who would be willing to check the situation. If the adjacent teeth have not move significantly, have them make a removable retainer or night guard that you can wear every night. It will help keep the adjacent teeth from moving into that space. You do not have to have the permanent abutment and crown done now, but you should do something. Unfortunately I have seen people who have waited too long and it has made it very difficult overcome the movement of the adjacent teeth. Good luck
