Root canal treatment may cause some discomfort, but it's usually not extremely painful.
Before the procedure, dentists often use local anesthesia to numb the area around the tooth. This significantly reduces pain during the treatment. You may only feel a little pressure as the dentist cleans out the infected pulp and shapes the root canals.
However, after the anesthesia wears off, some patients might experience mild to moderate soreness or sensitivity in the treated tooth for a few days. This can usually be managed with over - the - counter pain medications. In general, modern techniques and the use of anesthesia have made root canal treatment a more tolerable process than many people expect.
