A root canal might sound intimidating, but recognizing the signs early can save your tooth and ease discomfort. Common indicators include persistent tooth pain, sensitivity to hot or cold, swelling in the gums or jaw, tooth discoloration, pain when chewing, gum abscesses, and even a loose tooth. These symptoms often point to an infection or damage in the tooth’s pulp. Seeing a dentist promptly can prevent complications, relieve pain, and restore your oral health with a simple root canal treatment.
