Root canal is a treatment to repair and save a badly damaged or infected tooth instead of removing it.
Root Canal Treatment (RCT) also is known as Endodontic Treatment.It is done when the tooth decay reaches the pulp (innermost layer of the tooth) causing inflammation and pain. It is necessary to save the decayed tooth rather extracting it.
Symptoms
The most common symptom that one might need Root Canal Treatment is a toothache. The pain can range from mild to severe. With time it may worsen, and you will feel the pain even when you bite your food.
The other reason is prolonged sensitivity. If you feel sensations in your tooth while consuming something hot or cold, then there is the slightest chance that one needs to undergo Root Canal Treatment.
Swelling in the gums can also be a sign that you need Root Canal Treatment.
