A root canal is typically necessary when the soft tissue inside the tooth, known as the pulp, becomes infected or damaged due to decay, trauma, or a crack. Common signs that you may need a root canal include severe tooth pain, prolonged sensitivity to hot or cold, and swelling around the tooth or gums. If left untreated, an infected pulp can lead to an abscess, causing even more discomfort and complications. Dr. Swati’s Dental Care uses advanced diagnostic tools to identify the underlying cause of your symptoms and determine if a root canal is the best course of action. If you’re experiencing any of these warning signs, seeking dental attention promptly can save your tooth and prevent the infection from spreading. Ignoring these symptoms could lead to more serious health issues, including the potential for the infection to spread to other areas. Getting checked early gives you the best chance to preserve your tooth and avoid more complex treatments down the road.
