Hello!
I certainly understand your concern.
You can give a try by getting Re RCT done and if required surgery following it, but sucess rate will be just 20 % if recovers then that's the best part.
You need to wait for 3-6 months for it to recover completely, if there are no symptoms , u cannot expect changes immediately. There are cases which has showed good recovery and success.
If this fails then definitely extraction follwed by implants will be the only option left.
