Tooth Broken to the Gum Line

Hello there! Not to worry this is not an uncommon situation.  The retrieval of the remaining piece of tooth is quite simple and painless. Your dentist will NUMB the area, so you won't feel a thing. Once the root is delicately retrieved, using special dental instruments, you can replace the missing tooth with an implant (costly) or a bridge (a lot less costly).

It is most likely you need an extraction and bone preservation graft followed by an implant with a crown or a fixed, cemented, bridge.Another restorative option is a removable prosthesis like a retainer with a false tooth on it.The surgical removal of the hopeless tooth can be performed under sedation so that you are not aware of the process.Doug Jopling, DDS

As many have mentioned, a tooth broken to the gumline will likely need to be extracted. Before the dentist performs the procedure, he/she will give you adequate numbing to the area so you won't feel pain. Then, using thin instruments, the dentist will wiggle and elevate the tooth out of its socket. If you are particularly anxious about your procedure, I would consider asking your dentist if he or she offers any sort of oral sedation (like Xanax) or nitrous oxide (laughing gas) to help you during your procedure. Hope this helps!

That wire is the metal post your dentist placed to reinforce the stability of that crown that broke off.  Need to have that broke tooth (root) removed.  An implant or a bridge will be your best options, unless you already have multiple missing teeth, then another cheaper way is to get a partial denture will replace all of the missing teeth in that jaw.

Thank you for your great question. First of all I want  to reassure you that after getting the area numb, the only thing you will feel during procedure will be pressure, NO pain. Just like in removal of not broken tooth, doctor will wiggle it from side to side to loosen the ligament and make it easier to be removed. Depending how and where it broke, doctor might use a handpiece to remove a small amount of bone around a broken area to get access to the tooth. In any case you will not feel pain.
Do consider getting antiaxiety prescription from your dentist to make easier on you.
