A root canal helps you repair a decayed or infected tooth. The tooth's nerve and pulp are clearly removed and sealed. Since a tooth's nerve doesn't play an important role in a tooth's health and function after the tooth has emerged through the gums--Its only function is sensory--to provide the sensation of hot or cold. The presence or absence of a nerve will not affect the day-to-day functioning of the tooth.
What Are the Signs That a Root Canal Is Needed?
Sometimes no symptoms are present; however, signs you may need a root canal include:
Severe toothache pain upon chewing or application of pressure
Prolonged sensitivity/pain to heat or cold temperatures (after the hot or cold has been removed)
Discoloration (a darkening) of the tooth
Swelling and tenderness in the nearby gums
A persistent or recurring pimple on the gums
