What could cause the pulp to become inflamed or infected?
Decay, trauma, or extensive restoration of a decayed or cracked tooth may result in pulpal inflammation or infection. Pulpal inflammation is a common occurrence following a deep restoration (filling) or preparation for a full crown. Unfortunately, fillings do not last forever. Over time they can break down and begin to leak which can promote decay or small cracks in the underlying tooth structure. For this reason, fillings eventually need to be replaced or, in some cases, filled teeth may require the support of a full crown restoration. The very act of replacing a restoration or preparing a tooth for a crown may result in inflammation and a damaged pulp. Evidence of this inflammation may be extreme sensitivity to cold, heat, discoloration of the tooth, spontaneous pain, and pressure from biting. Endodontic treatment eliminates this sensitivity and allows the tooth to be healthy and functional.
