How Root Canal Treatment Saves Your Natural Tooth

A natural tooth can often be preserved when inflammation or infection inside the pulp is treated appropriately. With root canal treatment in Citrus Heights, CA, we remove the affected tissue, clean and seal the root canals, and help preserve the tooth when it can be restored.

What Is Root Canal Treatment?

Root canal treatment addresses infection or irreversible inflammation inside a tooth. We remove the affected pulp, clean and shape the canals, and fill and seal the space to help protect the tooth.

Why Teeth Need Root Canal Treatment

Deep decay, cracks, repeated dental work, or injury can affect the pulp. When the pulp cannot recover, root canal treatment may be recommended. We use an examination and dental X-rays to determine whether treatment is appropriate.

How Root Canal Treatment Helps Save the Tooth

Root canal treatment removes diseased tissue while preserving the outer tooth structure and roots. Keeping the natural tooth can help maintain chewing function and avoid leaving a space that may require replacement.

A 2024 systematic review and meta-analysis by Patel et al. examined the long-term survival of posterior teeth after nonsurgical root canal treatment. The review found that many treated teeth remained functional over time, while outcomes were influenced by factors such as remaining tooth structure, cracks, periodontal health, and tooth location. For this reason, we assess the condition of each tooth carefully before recommending treatment.

Signs You May Need a Root Canal

Possible signs include:

• Persistent tooth pain
• Lingering sensitivity to hot or cold
• Pain when biting or chewing
• Swelling or tenderness near the tooth
• A recurring bump on the gum
• Tooth discoloration

Some teeth may cause few noticeable symptoms, so evaluation is important.

What Happens During the Root Canal Procedure?

Treatment begins with an examination and dental X-rays. Local anesthesia is used to numb the area. We remove the affected pulp, clean and shape the canals, and fill and seal them. A temporary or permanent restoration may be placed depending on the treatment plan.

Root Canal Treatment vs. Tooth Extraction

Root canal treatment keeps the natural tooth in place by removing infected or inflamed tissue from inside it, while an extraction removes the tooth entirely. Preserving the tooth may help maintain chewing function and avoid the need to replace the missing tooth.

The appropriate option relies on factors such as the amount of existing tooth structure, the condition of the roots, and whether the tooth can be restored successfully. A dentist in Citrus Heights can examine the tooth and explain which approach may be appropriate.

Does Root Canal Treatment Hurt?

Local anesthesia helps keep the area numb during treatment. Some tenderness or sensitivity may occur afterward as the surrounding tissues recover. If discomfort becomes severe or does not improve as expected, contact our office.

The Role of Dental Crowns After a Root Canal

A crown may be recommended when a treated tooth has lost enough structure to need additional protection. A 2025 systematic review by Al-Meshal et al. found that the amount of remaining tooth structure can influence both restoration choice and long-term prognosis. We consider how much healthy tooth structure remains before recommending the final restoration, since not every root canal-treated tooth requires the same type of protection.

Recovery and Aftercare Tips

After treatment:

• Brush and floss as directed
• Wait until numbness wears off before chewing
• Avoid hard foods on the treated tooth until the final restoration is completed
• Follow instructions for any temporary filling or crown
• Contact our office if pain or swelling worsens

Risks of Leaving a Tooth Infection Untreated

An untreated infection can spread beyond the pulp and may lead to pain, swelling, or an abscess. If symptoms worsen, prompt dental care is important so the tooth and surrounding tissues can be evaluated.

How to Maintain Your Tooth After Root Canal Treatment

Continue brushing twice daily, clean between your teeth, and attend recommended dental visits. Complete any final restoration advised for the treated tooth, and avoid chewing hard objects or using your teeth as tools.

If you need a dentist near you to check a treated tooth, regular follow-up can help us monitor the restoration and surrounding tissues.
