Frequently asked questions
Can tooth pain go away on its own?
Pain can come and go, but the cause — such as decay or infection — usually does not heal without treatment. Have it checked before it gets worse.
Will I need a root canal?
Only an examination can tell. Root canal treatment is needed when the soft tissue inside the tooth is infected or badly inflamed.
