A root canal is one of the most common and important dental procedures used to save a severely damaged or infected tooth. Many patients feel nervous when they hear the term “root canal,” but in reality, modern dentistry has made this treatment comfortable, safe, and highly effective.
In Illinois, root canal treatment is widely available and performed by general dentists and endodontists (specialists in root canal therapy). However, one of the biggest concerns for patients is the cost.
In this detailed guide, we will break down the average cost of root canal treatment in Illinois (2026), what factors affect pricing, and what patients should expect before and after the procedure.
What Is a Root Canal?
A root canal is a dental procedure that treats infection or damage inside the tooth.
Each tooth has:
- Enamel (outer layer)
- Dentin (middle layer)
- Pulp (inner nerve and blood vessels)
When the pulp becomes infected due to decay, cracks, or trauma, a root canal is needed to remove the infection and save the tooth.
Root canal procedure includes:
- Removing infected pulp
- Cleaning inside the tooth
- Filling and sealing the canal
- Placing a crown for protection
Why Root Canal Treatment Is Needed
A root canal is recommended when:
- Deep tooth decay reaches the nerve
- Tooth is cracked or fractured
- Infection or abscess is present
- Severe tooth pain occurs
Without treatment, the infection can spread and lead to:
- Tooth loss
- Jaw bone damage
- Severe pain and swelling
