Infection: While you are waiting to see your dentist, see a provider for an assessment and antibiotics. See your dentist as soon as possible. All the best and I hope this feels better soon.
Dr. Susan Rhoads
Family Medicine 38 years experience
Infection: Any tooth can get an infection, a root canal does not prevent that or make it more likely. Get seen today or call your doc or dentist. Any doc can start antibiotics and treat the pain until you can get seen by your dentist. If you have fever, trouble swallowing, rapidly increasing swelllng or redness of the cheek or face go to the ER. Gook luck!
Dr. Kenneth Grossman

Infection: you have an infection. There are many possible causes. Possible fractured root,failing root canal, abscess that won't heal without being removed,etc! Get to an Endodontist,ASAP!
Dr. Arnold Malerman

Infection: Your symptoms suggest infection. May be from untreated canal, fracture, infected adjacent tooth, unsealed canal, failure of overlying restoration, etc. Return to the Dentist or Endodontist that did the original root canal treatment for review, treatment, or referral.
