Unfortunately this space won't disappear and if this is bothering you, you will need a new crown.
It is normal to have a dull ache with a temporary crown. The margins are not sealed properly with a temporary and because of the work that has been done, tooth can be sensitive up to 2 weeks. Always discuss your issues with your dentist before your permanent crown is cemented.
it wouldn't unless you have very short roots or mobility. It also depends if the dentist wants to do a gingivectomy( just trimming gum) or crown lenghtening which is more invasive and requires some bone trimmimg.
Always consider implant option before replacing your bridge. Talk to your dentist to go over your options and see if you are a candidate for implatn. The only problem when you are replacing an existing bridge with implant is the need to crown again the abutments used for your previous bridge, but with the new implant you can floss and keep the area clean much easier. Just remember if you have a bridge and there is a problem with one of your abutments, the whole bridge needs to be replaced.
If you are happy with the rest of your teeth and you only have one front tooth with a chip or discoloration, you sure don't want have other teeth crowned or veneered. The trick to get your single veneer or crown to match is the communication with the lab and the doctor. one or two trips to the lab are needed for custom shade. The lab usually makes the crown and try it in your mouth, if the color is good, they can go to finish, But most time a second try-in is needed.
