It's the part of a tooth where it braches into two (or more) roots. If you imagine a pair of pants, it would be the crotch area of the pants.
what is the difference between a surgical tooth and a erupted toothExtraction of erupted tooth refers to the dentist physically pulling out the tooth due to whatever trauma it has undergone. Extraction of the root is going into the tooth and drilling out the roots, like a root canal.
Normally, upper molars have three roots. I have seen strange ones with four, and again sometimes second or third upper molars may have their roots fused together and appear to only have one or two.
Sometimes an infection in a tooth becomes abscessed. At that point, it becomes necessary either to pull the tooth or to clean out the root and fill it. A root canal means the dentist cleans out the root of the tooth. He or she drills out the nerves and blood supply to the tooth. The tooth may have one, two, three, or four roots. Each root is cleaned out, filled, and then a regular filling is placed in the rest of the tooth.

If you look at a picture of a tooth, you will see the crown of the tooth. That is the top part that is above your gum. The root(s) are the anchors. Some teeth have one root and some have a few. Easy chart I found online: Laterals have one root (these are your front teeth) Canines and most premolars, except for maxillary (upper) first premolars, usually have one root. Maxillary (upper) first premolars and mandibular (lower) molars usually have two roots. Maxillary (upper) molars usually have three roots.
