A temp crown caused problems eating, inflamed gums and bleeding. What should I do? (photo)

If you're having throbbing and an infection, then your dentist is most likely correct regarding a root canal treatment to remove the infection and stop your pain, and most likely help you from eventually losing your tooth.It is easy for your dentist to get you numb with local anesthetic, and remove your temporary and recement it.  Sometimes a temporary is leaking or not fitting properly or the bite needs adjustment, and your dentist would make the best call if any of those things are going on.Also, don't compare how your temporary crown looks and fits compared to the new crown you will be getting.Temporary crowns almost never fit and look as good as the permanent crowns.Sometimes, when the dentist suspects that the tooth might settle down with time he will temporary cement the new crown and give the tooth a chance to settle down before making the decision on whether or not to do a root canal.  Other times it is obvious that root canal will be necessary regardless, and waiting serves no purpose other than delaying solving your pain and infection issues.

Hello,I'm sorry that you are in pain. I suggest you get immediate attention; due to the gum condition there's not only inflammation but also trapped bacteria. Root canals are not that expensive, and they can be performed in 1 appointment, post and core, with a porcelain crown,would be absolution, also check the adjacent teeth ,as they look on that picture,they need service soon.You should consult your dentist or consider finding someone you feel 100% confident that will help you with this.
