HI! I have had a root canal on the same tooth twice, and the second time it was because of an infection. They put a metal crown on the tooth after the second root canal, but now, 3 years later, the tooth is starting to hurt and throb when Im chewing. Is it an infection? And do I need another root canal?
Hi. Welcome to Chat Doctor . I have gone through your query and can understand your concern. As per your complaint it is true that after Root Canal Treatment if there is pain again after few months or years it is due to re-infection in the tooth and in case if after doing Root canal twice also again pain has started that means there are some defects in the root canal treatment which is causing re infection and pain. I would suggest you to consult an Endodontist and get evaluated and in case if there is infection I suppose after an x Ray you will be advised to get the tooth extracted as it is not responding to Treatment. As for now you can take anti-inflammatory painkillers like Ibuprofen for pain relief and Augmenting 625\u00a0mg for reducing infection. Avoid chewing from affected side. Hope this information helps.
