What Causes Tooth Abscess After A Root Canal Treatment?

Hi I have an abcess tooth and it is from a root canal that wasn't properly all taken out. I went to the dentist the day after my tooth started having horrible pains. The day I went is the day my face swelled up and it's been swelled up for about 3 days and I have been taking amoxicillin for the 3 days. I went to the dentist and he opened my gums a little bit and also did a root canal on my tooth. He didn't finish because he isn't a specialist but I'm going to one Monday. Will the swelling go down and will I be okay? I'm so nervous about it spreading.

Hi Dear,

Welcome to HCM.

Understanding your concern. As per your query you have symptoms of tooth abscess after a root canal treatment as sometimes infection remains even after root canal of teeth and build up pressure and move into facial spaces leading to facial space infection. Need not to worry. I would suggest you to maintain proper oral hygiene and avoid intake of sharp and cold food substances. You should consult dentist for proper examination. Doctor may order X-ray for proper evaluation. Doctor may consider root canal again or extraction of tooth depending upon the condition of the tooth. Doctor will also prescribe antibiotics ( penicillin or metronidazole ) at least for 10 days .

Hope your concern has been resolved.

Get Well Soon.

Best Wishes,
Dr. Harry Maheshwari
