Relieve Pain and Save Your Tooth with Professional Endodontic Care
Dentist Grants Pass
Endodontics focuses on treating the inner tissues of the tooth to relieve pain, eliminate infection, and preserve your natural tooth structure. When the pulp inside a tooth becomes inflamed or infected, often due to deep decay, trauma, or a crack, root canal therapy is the most effective way to resolve the issue while saving the tooth from extraction. This treatment involves gently removing the damaged pulp, cleaning and disinfecting the root canals, and sealing the space to prevent future infection. Although root canals have a reputation for discomfort, modern techniques and technology make the process efficient and surprisingly comfortable. Dr. Niklaus Spendlove provides precise, compassionate care, using advanced diagnostics and a steady, gentle approach to ensure your treatment is successful and stress-free. By preserving the natural tooth, root canal therapy supports long-term oral function, eliminates the need for extraction, and helps maintain the natural alignment of your smile. If you’re experiencing tooth pain or sensitivity, timely endodontic care can make all the difference in restoring your health, comfort, and peace of mind, all while helping you keep your natural tooth.

| Endodontic Treatment Finding | Percentage | What the Data Shows |
|---|---|---|
| Teeth retained 8 years after initial root canal treatment | 97% | A large Journal of Endodontics study reported that 97% of treated teeth remained in the mouth eight years after initial nonsurgical root canal treatment. |
| CBCT-assessed tooth healing under broader criteria | 87% | A systematic review found an 87% pooled healing rate when teeth showing complete or partial radiographic healing were included. |
| CBCT-assessed root healing under broader criteria | 84% | When individual roots were evaluated under the broader criteria, the pooled healing rate was 84%. |
| CBCT-assessed tooth success under broader criteria | 85% | The pooled tooth-level success rate was 85% when the review applied broader outcome criteria. |
| CBCT-assessed tooth healing under strict criteria | 36% | When healing required complete radiographic resolution on CBCT imaging, the pooled tooth-level healing rate was 36%. |
| CBCT-assessed tooth success under strict criteria | 45% | The pooled success rate was 45% when strict CBCT criteria required complete resolution rather than allowing partial healing. |

What Grants Pass Patients Should Know About Endodontic Services
Endodontic treatment addresses problems inside the tooth
Root canal treatment may be recommended when the dental pulp becomes inflamed, infected, or unable to heal.
Treatment is intended to preserve the natural tooth
The affected pulp is removed, the internal canal system is cleaned and shaped, and the space is sealed.
Symptoms can vary
Persistent tooth pain, prolonged temperature sensitivity, pain when biting, gum swelling, or a recurring pimple on the gums may indicate a problem requiring evaluation.
Some affected teeth cause few symptoms
Changes involving the pulp or tissues around the root may be identified during an examination or on a dental X-ray before the patient experiences significant pain.
The tooth usually needs a final restoration
Depending on the tooth and the amount of remaining structure, a filling or crown may be recommended after root canal treatment.
Follow-up care evaluates healing and function
Dr. Spendlove may monitor symptoms, the restoration, the patient’s bite, and the tissues surrounding the root after treatment.

“When the tissue inside a tooth becomes inflamed or infected, I evaluate whether root canal treatment can preserve the natural tooth. My goal is to remove the affected tissue, disinfect and seal the canal system, and help the patient return to comfortable function.”
Dr. Niklaus Spendlove
Questions Grants Pass Dental Patients Ask
What endodontic services does Spendlove Dental provide?
Spendlove Dental provides root canal treatment for teeth with inflamed, infected, or damaged pulp. Dr. Spendlove evaluates the tooth to determine whether treatment is appropriate.
What happens during root canal treatment?
The affected pulp is removed from inside the tooth. The canal system is then cleaned, shaped, disinfected, filled, and sealed to help prevent additional contamination.
How does a patient know whether a root canal may be needed?
Possible signs include persistent tooth pain, lingering sensitivity to heat or cold, pain when chewing, swelling, or a recurring bump on the gums. An examination and dental imaging are needed to identify the cause.
Is root canal treatment painful?
Local anesthesia is used to numb the treatment area. The purpose of treatment is to address the inflamed or infected tissue that may be causing pain, although temporary tenderness can occur afterward.
Does a root canal-treated tooth need a crown?
Some root canal-treated teeth require crowns, particularly back teeth or teeth with extensive structural loss. Dr. Spendlove evaluates the remaining tooth structure, location, and bite before recommending the final restoration.
Can a root canal-treated tooth develop another problem?
Yes. A treated tooth can fracture, develop leakage around its restoration, or experience persistent or recurrent infection. New pain, swelling, biting discomfort, or damage to the restoration should be evaluated.
