With growing technology, many ways have been found out to repair or fix broken teeth. Some lucky ones get their real tooth reattached before its death.
Rebuilding of injured tooth depend on many factors. Primarily it depends on the state of tooth and it's socket once a patient arrives for surgery.
A tooth that has been completely broken and removed from its place but it is in strong condition, can be placed back into its place provided there is enough
time for it to repair.
In case tooth has been out from the mouth from last 1 hour or so, then chances of attachment are slim.
If there is past history of gum disease or tooth decay before the breakage of tooth, dentist will likely not attempt to reattach the tooth and will opt to replace the tooth with either a ceramic or a titanium implant.
