What is a Root Canal?

A root canal is the tiny channel within the tooth that runs from the top of the tooth down to the tip of the root. It contains nerves, blood vessels, and other tissues that help keep the tooth healthy. When these tissues become infected or damaged, root canal therapy is necessary to remove the damaged tissue and protect the rest of the tooth from further damage.

What Causes the Need for a Root Canal?

There are several factors that can cause the need for a root canal, including:

• Decay: Tooth decay can cause the nerve and blood vessels in the root canal to become infected.
• Trauma: A traumatic injury to the tooth can cause the nerve and blood vessels in the root canal to become damaged.
• Large Fillings: Large fillings can put pressure on the nerve and blood vessels in the root canal, causing them to become damaged or infected.
• Gum Disease: Advanced gum disease can cause the tissues in the root canal to become infected.
