Dental Decay (Root Surface)
As one ages, the incidence for decay can increase, especially root surface
decay. The exposure of the tooth's root surface occurs in seniors primarily
from gum tissue receding as one ages. Root surfaces do not have a protective
enamel layer and are primarily composed of softer cementum, which easily
decays. Plaque and bacterial accumulation can collect on these surfaces
increasing the risk for this type of decay. Since the root surface lacks
enamel, decay can more easily penetrate the tooth's pulp (nerve), which
can cause endodontic (root canal) problems and in worst scenarios, tooth
loss. Older fillings may also wear and fracture as one ages causing weakening
or loss of teeth.
