Hi, I recently had two gold crowns put onto two of my right lower molars, however it has been two wks and I am stii have sensivity to cold and a bit of tenderness to a stong bite when I chew on that side of my mought.  My dentist told me that my teeth did not need a root canal and the caps were put on pefectly and that I should give my tooth some time to settle and adjust the crown.  I have had crowns done b4 and this did not happen and I am worried that something is wrong and the crowns will have to removed and re installed to fix what is wrong but my dentist thinks that in time it would be okay with soem prescription strenght floride toothpaste but I do not know what to believe or do.
Hi Dear, Welcome to Chat Doctor. Understanding your concern. As per your query you have symptoms of cold sensitivity and tenderness in teeth after a root canal which is due to accumulation of pus below the root tips of the tooth and which sometimes occur due to leftover infection even after root canal. Sometimes sensitivity occurs due to nerve injury. Need not worry. I would suggest you to consult endodontist again and get evaluated and get IOWA(x-ray) of that tooth done to find any infection. Doctor may irrigate tooth and can prescribe antibiotics along with anti-inflammatory medications. Avoid intake of sharp and sticky food. For now take ibuprofen or acetaminophen for pain and do warm saline rinses several times a day. Hope your concern has been resolved. Get Well Soon. Best Wishes,
