What Is a Root Canal?
A root canal is a procedure that removes infected or damaged pulp from inside a tooth. After cleaning and disinfecting the area, the tooth is sealed to prevent reinfection. In many cases, your dentist will place a crown over the tooth for added strength and protection.
What Causes a Tooth Infection?
A tooth infection develops when bacteria reach the inner pulp of a tooth, leading to inflammation and pain. Some of the most common causes include:
- Deep Decay: An untreated cavity allows bacteria to spread inside the tooth.
- Cracks or Fractures: Even a small crack can expose the pulp to infection.
- Repeated Dental Work: A tooth that has undergone multiple treatments may weaken over time.
- Injury: Trauma to a Tooth, even if it looks fine on the outside, can damage the pulp and lead to infection.
Does a Root Canal Hurt?
Many people worry about pain during a root canal, but the procedure itself is not painful. With local anesthesia, you’ll feel little to no discomfort while the infection is treated. In fact, most patients find that a root canal provides relief from the pain caused by the infection.
What Happens During the Procedure?
A root canal typically involves four steps:
- Numbing the Area: Local anesthesia ensures comfort throughout the procedure.
- Removing the Infection: The damaged pulp is carefully extracted.
- Disinfecting and Sealing: The inner chamber is cleaned and sealed to prevent further issues.
- Restoring the Tooth: A filling or crown is placed to strengthen and protect the tooth.
How Long Does a Root Canal Last?
A treated tooth can last a lifetime with proper care. Brushing, flossing, regular dental checkups, and avoiding excessive pressure on the tooth will help maintain its strength and function for years.
