The use of local anesthesia by the dentist who performs root canals should ensure that you experience minimal or no pain.

While infection is commonly the initial indicator, you may not experience any apparent symptoms. It is possible for your dentist to identify the damage during a regular check-up. However, you may observe some indications of diseased pulp, such as heightened or persistent sensitivity to heat, cold, or pressure, discoloration of the tooth, a sizable cavity, an unpleasant taste in your mouth despite brushing, pus draining into your mouth, and inflamed or tender lymph nodes.

Regrettably, the bacteria and infection have the potential to spread to other areas of your mouth, leading to the development of a dental abscess that necessitates immediate intervention.

The innermost layer of your tooth is called the tooth pulp, which consists of blood vessels, nerves, and connective tissues that extend to the roots. The pulp is responsible for three essential functions, including sensing hot and cold, forming dentin (the hard secondary layer), and nourishing the tooth through blood vessels. Despite its numerous contributions to tooth health, the pulp is not indispensable for tooth survival, as the surrounding tissues can provide sufficient support.
