Root Canal Treatment in Corona, CA

What Is Root Canal Treatment?

A root canal is a dental procedure that removes infected or damaged pulp from inside a tooth, cleans and disinfects the root canals, and seals the tooth to prevent reinfection. Root canal therapy saves a natural tooth that would otherwise require extraction. At SmileNOW Dental in Corona, CA, we perform root canals with precision and care — most patients are surprised by how comfortable the procedure actually is.

Signs You May Need a Root Canal

• Severe, persistent toothache — especially throbbing or pressure pain
• Prolonged sensitivity to hot or cold that lingers after the stimulus is removed
• Darkening or discoloration of the tooth
• Swollen, tender gums near the affected tooth
• Pimple on the gum (abscess/fistula) — a sign of infection draining
• Cracked or chipped tooth with pain — bacteria can enter through cracks
• Deep decay that has reached the tooth’s pulp

The Root Canal Process at SmileNOW Dental

1. Diagnosis and X-ray — We take digital X-rays to assess the infection and confirm root canal treatment is needed.
2. Local Anesthesia — The area is fully numbed before any treatment begins. You will feel pressure but no pain.
3. Access Opening — A small opening is made in the top of the tooth to access the pulp chamber.
4. Pulp Removal — Infected or damaged pulp tissue is removed using specialized files.
5. Canal Cleaning and Shaping — The canals are cleaned, shaped, and disinfected with antimicrobial solution.
6. Sealing — The cleaned canals are filled with a biocompatible material (gutta-percha) and sealed.
7. Crown Placement — A dental crown is placed over the treated tooth to restore full function and protect it from fracture. This is typically done at a follow-up visit.

How Long Does a Root Canal Take?

Most root canals at SmileNOW Dental are completed in a single appointment lasting 60–90 minutes. Complex cases or molars with multiple canals may require a second visit. Crown placement is a separate appointment, typically 1–2 weeks later, lasting 45–60 minutes.

Root Canal vs. Tooth Extraction: Which Is Better?

In most cases, saving your natural tooth with a root canal is the better long-term choice. Natural teeth are stronger than any replacement, and extraction triggers bone loss in the jaw over time. Tooth replacement options (implants, bridges) typically cost more than a root canal and crown combined. SmileNOW Dental always recommends preserving your natural tooth whenever possible.

Root Canal Recovery: What to Expect

• Mild tenderness or sensitivity for 2–3 days after treatment — normal and expected
• Over-the-counter ibuprofen (Advil) or acetaminophen (Tylenol) manages discomfort effectively
• Avoid chewing on the treated tooth until the permanent crown is placed
• Most patients return to normal activities the day after treatment
• Call our office if you experience severe pain, swelling, or the temporary filling comes out

Does Insurance Cover Root Canals in California?

Most PPO dental insurance plans classify root canal treatment as a “major” procedure and cover 50–80% after your deductible. SmileNOW Dental verifies your benefits before treatment and provides a clear cost estimate. For any remaining balance, we offer 0% financing through CareCredit and Sunbit — apply in minutes with same-day approval.

Root Canal Treatment in Corona, CA — Frequently Asked Questions

How do I know if I need a root canal or just a filling?

A filling treats surface or shallow decay. A root canal is needed when decay or damage has reached the inner pulp of the tooth, causing infection or nerve damage. Signs you need more than a filling: spontaneous pain, lingering sensitivity to temperature, swelling, or a visible abscess. An X-ray at SmileNOW Dental will confirm which treatment is appropriate.

Can I wait on a root canal?

No — and waiting makes it worse. A tooth infection does not resolve on its own. Left untreated, the infection spreads to surrounding bone and tissue, can enter the bloodstream, and the tooth typically becomes unrestorable, requiring extraction. Early treatment is always less expensive and less complex than delayed treatment.

Will I need a crown after a root canal?

Almost always yes, especially for back teeth (premolars and molars). The root canal procedure removes pulp that provides nutrients to the tooth, making it brittle over time. A crown protects the treated tooth from fracture during normal chewing. Front teeth sometimes only need a filling, but a crown is still often recommended.

How long does a root canal last?

With proper care and a crown, a root canal-treated tooth can last a lifetime. Success rates for root canal treatment are 85–97% at 8 years. Good oral hygiene, regular cleanings, and protecting the crown are key to long-term success.

Is a root canal better than pulling the tooth?

In almost every case, yes. Saving your natural tooth preserves bite force, prevents adjacent teeth from shifting, and avoids the bone loss that follows extraction. Tooth replacement (implant + crown) typically costs $3,000–$5,000 — more than a root canal and crown combined. SmileNOW Dental always prioritizes saving your natural tooth first.

Can antibiotics cure a tooth infection without a root canal?

No. Antibiotics reduce infection temporarily but cannot eliminate the source of infection inside the tooth. The infection will return — often worse — once the antibiotic course ends. Root canal treatment removes the infected tissue permanently. Antibiotics may be prescribed alongside root canal treatment, not instead of it.

What happens if I don’t get a root canal?

The infection progresses, causing increasing pain and swelling. The tooth becomes abscessed and may require extraction. The infection can spread to the jaw, neck, or — in rare severe cases — the bloodstream (sepsis). Dental infections are medical emergencies when left untreated. Call SmileNOW Dental immediately if you have symptoms.
