Root cannal

Hi. I have recently undergone a root canal treatment. And a permanent crown is fitted. what are the chances of the same tooth being infected. As per my understanding during root canal procedure, the nerves are removed. So how can I sense if the same tooth is infected again.

Look for your gums if they show any redness in that area Look for any recent food lodgements in crown areas often indicates secondary decay has started In case of re infection after root canal- tooth may become tender on chewing. In rare cases you may see a soft tissue swelling to your crown In extreme cases you may see mobility in the cap due to destruction of underlying tooth (after excluding other factors) Don't worry much.. Just brush twice a day...
