What Is a Root Canal? Everything You Need to Know

What Is a Root Canal?

A root canal is a dental procedure used to remove infected or damaged pulp from inside a tooth. The tooth is then cleaned, disinfected, and sealed to prevent further infection and relieve pain.

According to the American Dental Association, root canal treatment is designed to save natural teeth and prevent the spread of infection.

When Do I Need a Root Canal?

You may need a root canal if you experience:

• Severe or persistent tooth pain

• Sensitivity to hot or cold

• Swelling or tenderness in the gums

• A cracked or deeply decayed tooth

An exam and dental X-rays are required to confirm the diagnosis.

Is a Root Canal Painful?

Root canal treatment is performed under local anesthesia, making the procedure comfortable. Most patients report feeling relief from pain after treatment rather than discomfort during the procedure.

How Long Does a Root Canal Take?

Most root canals can be completed in one visit, although complex cases may require two appointments. Treatment time depends on the tooth being treated and the severity of infection.

How Long Does a Tooth Last After a Root Canal?

With proper care and restoration, a tooth treated with a root canal can last many years—or even a lifetime. Good oral hygiene and routine dental visits are essential for long-term success.

Will I Need a Crown After a Root Canal?

In many cases, especially for back teeth, a dental crown is recommended after root canal treatment. A crown helps protect the tooth, restore strength, and prevent future damage.

What Happens If I Delay a Root Canal?

Delaying treatment allows infection to spread and may lead to:

• Increased pain

• Abscess formation

• Bone loss

• Tooth loss

Prompt root canal treatment helps save your natural tooth and prevent complications.

How Should I Care for My Tooth After a Root Canal?

After treatment:

• Brush and floss daily

• Avoid chewing on the treated tooth until it is fully restored

• Attend regular dental checkups

Proper care helps ensure long-term success.

Are There Alternatives to Root Canal Treatment?

The main alternative to a root canal is tooth extraction. However, saving your natural tooth with root canal treatment is often the best option for long-term oral health and function.

How Much Does a Root Canal Cost?

The cost of a root canal varies depending on the tooth location and complexity of treatment. A consultation is the best way to receive a personalized treatment plan and accurate estimate.

Can a Root Canal Get Infected Again?

While uncommon, reinfection can occur if the tooth is not properly sealed or restored. Regular dental visits help monitor and maintain the treated tooth.

Final Thoughts on Root Canal Treatment

Root canal treatment is a safe and effective way to relieve pain and save an infected tooth. Early treatment helps prevent complications and protects your long-term oral health.
