Definitions for "Root Resorption"
Resorption of a part of the root of a tooth. Either internal (pulpal) or external surfaces may be affected, generally at the apex.
Term used to describe dissolution/dissolving of the root of a tooth. Resorption occurs naturally when permanent teeth erupt and dissolve the roots of baby teeth, causing the baby tooth to fall out. Resorption can also happen spontaneously during orthodontic treatment or as the result of one permanent tooth erupting across another, damaging the root.
The "eating away" or dissolving of areas both inside and outside the tooth root. This is particularly common after trauma.
