I went to the dentist because of pain in my lower left first premolar. The regular dentist performed a on this tooth. The pain did not go away and I developed an infection. The regular dentist asked me to see a specialist. I went to an who said I needed a canal re-treatment. A few days later, I still have the pain and infection. I was advised to see an to have the tooth extracted. I then got a to replace it but the pain has not gone. I have been to different dentists but none of them could find anything wrong. They kept on telling that my bite was the culprit, however after some adjustments, the pain remained. Any ideas? What should I do now? I would be grateful for any advice you can give me.
