Root canal treatment is necessary when the pulp inside the tooth becomes inflamed or diseased. The pulp consists of blood vessels, connective tissue, and nerves. During root canal therapy, the dentist will remove the diseased pulp and then clean and seal the pulp chamber of the tooth. Most of the time, root canal therapy is a relatively simple procedure with little discomfort. Best of all, it can save you from losing a tooth!
Causes of an infected pulp could include:
a deep cavity
a cracked or broken tooth
injury to a tooth (even if there’s not a visible crack or chip)
