Root Canals: What to Expect, Pain Relief, and Aftercare
Root canal treatment saves millions of teeth each year. If you're facing one, you probably wonder what actually happens, whether it hurts, and how to recover fast. A root canal removes infected pulp inside a tooth, cleans the space, and seals it to stop pain and infection. Here's a clear, practical guide so you know what to expect before, during, and after the procedure.
How to tell if you need a root canal: a sharp or dull toothache that won't quit, pain that lingers after hot or cold, swelling near the gumline, a darkened tooth, bad taste or pus, or intense pain when biting. Sometimes there are no major symptoms and an X-ray shows deep decay close to the nerve. Don’t ignore persistent tooth pain; early treatment often means a simpler procedure and better outcome.
What happens during the visit: your dentist will take X-rays and numb the area with local anesthesia. The tooth is opened to remove diseased pulp, the canals are cleaned, shaped, and disinfected. The space is filled with a rubbery material and sealed. Many teeth get a temporary filling first, then a permanent crown later to restore strength. Most procedures take one or two appointments depending on the case.
Will it hurt? Modern root canals are much less painful than old stories suggest. The nerve is removed, so the procedure is done under anesthesia and most people feel pressure more than pain. You may have soreness for a few days once the numbing wears off. Over-the-counter pain relievers like ibuprofen usually handle that. Call your dentist right away if you get severe swelling, fever, or uncontrolled pain.
Aftercare and recovery are simple: avoid chewing on the treated tooth until the permanent crown is in place, stick to soft foods for a day or two, and keep brushing and flossing gently. A warm saltwater rinse eases gum soreness. Most people return to normal eating and activity within 48 to 72 hours.
Success rate and risks: root canals work well—success ranges from about 85% to over 95% when done correctly and followed by a crown when needed. Risks include reinfection, missed canals, or fracture of a weakened tooth. If a root canal isn’t possible, extraction followed by an implant or bridge are common alternatives. Talk through pros and cons with your dentist.
Cost and choosing a provider: root canal cost varies by tooth location and whether an endodontist performs it. Molars cost more than front teeth. Always ask for an itemized estimate that includes the crown. If anxiety is an issue, ask about sedation options. Look for providers with good reviews, clear communication, and a willingness to explain the steps and follow‑up care.
Quick answers: yes, a root canal can save a tooth and relieve pain; the restored tooth can last many years with good care. If you have sudden severe pain, swelling, or a persistent sore, contact your dentist promptly.
Request written aftercare instructions and a follow-up visit to confirm healing and crown fit soon with dentist.
