Root canal treatment is a dental procedure to remove inflamed or infected pulp on the inside of the tooth which is then carefully cleaned and disinfected, then filled and sealed. Root canal treatment is designed to eliminate bacteria from the infected root canal. Root canals are needed for a cracked tooth from injury or genetics, a deep cavity, or issues from a previous filling. Patients generally need a root canal when they notice their teeth are sensitive, particularly to hot and cold sensations.

There are a few symptoms that mean you might need a root canal-

• Severe pain while chewing or biting
• Pimples on the gums
• A chipped or cracked tooth
• Lingering sensitivity to hot or cold, even after the sensation has been removed
• Swollen or tender gums
