Standard taper

Sometimes a tooth needs a root treatment.
This requires the exposure of the root system of the tooth …
… then the removal of the nerves and material within the root.
A special material is now available …
… which is placed into the tooth roots.
The material hardens and is then trimmed.
The tooth can then be filled.
Over time, this special material expands within the root …
… which prevents any bacteria from continuing to deay the tooth.
