Internal/external resorption



In dentistry, resorption is a term used when referring to changes that take place with respect to the roots of your teeth that are not exclusively the result of decay or fracture.


There are two areas where resorption can start, internally and externally. Internal resorption starts at the innermost surface of your tooth's root and external resorption, as the name implies, starts at the outermost surface where your tooth's root connects to your jawbone through the ligament that holds it within its socket.   Both processes are destructive in nature and can lead to the loss of your tooth without treatment.
