ENDODONTICS

Pulp and bone care 

The pulp,  which contains the nerves and blood vessels that keep the tooth alive, is normally surrounded and protected by a layer of dentin covered by enamel above the gumline and cementum underneath.

When a deep cavity or crack destroys these protective layers, the pulp is exposed to the bacteria in your mouth. A severe blow to the tooth can also damage the pulp. This can result in inflammation, infection and, eventually, necrosis (pulp death).

Irritants may then escape from the end of the root and cause a diseased area (apical lesion) in the bone.

Root canal treatment removes the damaged pulp and irritants. This allows the bone surrounding the root end to repair and heal.
