Thanks so much for your response.
It looks like that the tooth which was repaired was infected. That is why you have pain and facial sensitivity. For this you have to go to the dentist and get it examined. If there is a infection than you have to get the root canal treatment done. for more info on root canal treatment you can visit the following link........http://www.identalhub.com/article_why-is-root-canal-treatment-rct-required-299.aspx
