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.
