Root canal is a treatment to repair and save a badly damaged or infected tooth instead of removing it. The procedure involves removing the damaged area of the tooth (the pulp) and cleaning and disinfecting it, then filling and sealing it. The common causes affecting the pulp are a cracked tooth or a deep cavity.
Decades ago, root canal treatments were painful. With dental advances most patients experience very minimal pain during the treatment process.
- Toothache. Pain can range from mild to severe. it may lessen or intensify throughout the day, or it may get worse even when you bite down on the tooth
- Prolonged sensitivity to food or even liquids.
- Swelling of gums also could be one of the symptoms
