Finding symptoms early is very important. These are some common signs that a tooth may need a root canal:
Pain when chewing or sudden pain
If you feel pain when eating, even if the tooth looks normal, it may mean the pulp is inflamed or infected.
Sometimes, the pain can start suddenly and strongly, even without chewing. This is a sign that the tooth needs immediate attention.
Darkening of the tooth
A strong hit or trauma can damage the nerve of a tooth and cause it to change color.
When a tooth becomes darker, it can mean the blood flow inside is affected, and a root canal may be needed to save the tooth.
Swollen gums
When the root of a tooth is infected, the gums and nearby tissues can also become swollen.
Swelling that does not go away, feels painful, or is sensitive to touch can be a sign that a root canal is necessary.
Bad taste or bad smell in the mouth
An untreated infection in the tooth root can cause a dental abscess. This may produce pus, a bad smell, or a bad taste in the mouth.
A root canal removes the infection and helps restore oral health, relieving these uncomfortable symptoms.
