Many factors can contribute to tooth pain following crown placement. Usually it is mal-occlusion or improper bite. However, if the dentist has repeatedly checked and properly adjusted the bite, then the nerve of the tooth may be the culprit. In this case you may need a root canal to remove the inflamed nerve, and you should notice a huge improvement in sensitivity and pain coming from that tooth.
Yes, you can have a root canal performed and a crown placed to avoid an extraction IF there is enough healthy tooth structure without major infection to support this dental treatment. In some cases of severe trauma, the tooth can not be saved.
A veneer could possibly be done as an alternative, but the ideal treatment would be to get a full crown. It will be more reliable than a veneer
This is not an issue. In fact it is better to do #22-27 at the same time so that the esthetics, anatomy, and color can be matched
You have an open contact and will have to get the crown replaced for a larger crown. If you have a natural tooth adjacent to the crown, then you can possibly have a filling placed on that natural tooth, to help close the gap. These open contacts cause food traps, which lead to periodontal problems of the gum and bone surrounding the teeth.Talk to your providing dentist as to whether this is something you would have to pay for again, often times they may re-do it free of charge if you explain the situation.
