When is a root canal needed? It’s usually required when the tooth’s pulp is infected or inflamed due to decay or injury. Symptoms like sharp pain, prolonged sensitivity, or gum swelling are clear signs. A root canal is essential to remove the infection, relieve pain, and prevent tooth loss. If you notice any of these issues, visit your dentist early to avoid complications and protect your natural smile.
