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.

What Happens During a Root Canal Procedure?

A root canal procedure typically takes one or two visits to the dentist. During the procedure, the dentist will numb the area around the tooth to reduce discomfort. They will then make a small hole in the top of the tooth to access the root canal.

Next, the dentist will remove the infected or damaged tissue from the root canal and clean and shape the canal to prepare it for filling. They will then fill the canal with a rubber-like material called gutta-percha and seal the tooth to prevent further infection.

Finally, the dentist will place a crown over the tooth to protect it and restore its function. The crown will also help to prevent further damage to the tooth.
