When a tooth’s nerve becomes inflamed or infected, root canal therapy can stop the pain, remove the infection, and preserve your natural tooth. Thanks to modern techniques and anesthetics, the procedure is typically as routine as getting a filling—just a bit longer. Here’s a clear look at when you need a root canal, what happens during treatment, how recovery works, and how Marlton Modern Dentistry keeps you comfortable throughout.
Deep decay, cracks, large fillings, or trauma can allow bacteria to reach the pulp (nerve tissue). Symptoms include lingering sensitivity to hot or cold, spontaneous pain, pressure pain when biting, or swelling. Sometimes there are no symptoms at all, and an X-ray reveals the problem. Root canal therapy cleans the inside of the tooth and seals it so infection can’t return.
Expect mild tenderness for a day or two, manageable with over-the-counter medication. Avoid chewing hard foods on the treated tooth until the final crown is placed. Keep up with brushing, flossing, and follow-up appointments so we can protect the long-term success of your treatment.
Untreated infection can spread, causing swelling, bone loss, and more extensive treatment needs later. Additionally, pain often intensifies over time and can affect sleep, work, and appetite. Quick diagnosis and treatment are your best path to relief.
Root canal therapy has a high success rate, especially when followed by a well-sealed crown and consistent hygiene. With routine exams and cleanings, many treated teeth last for decades.
