Could the persistent cheek pain be caused by the spread of infection through the sinuses?

Hello,

Welcome to icliniq.com.

If, after repeating the root canal treatment, the pain and sensitivity persist, it might be related to the last tooth behind the treated tooth. You may have deep gingival pockets between these two teeth, causing sensitivity due to food particles touching the root of the last untreated tooth. So, it may be advisable to ask your dentist whether it can be treated as well to provide better relief.

Thanks and regards.

Hello,

Welcome back to icliniq.com.

A root canal-treated tooth does not have any nerves inside it, which can cause sensitivity. It is better to stop using floss there for a couple of weeks and instead use warm salt water gargle twice a day to allow the gums to heal. If food is getting stuck between those teeth, then there is indeed a large gap or gingival pockets. In this case, use interdental brushes to remove the food debris. Also, consider using desensitizing toothpaste to get relief from sensitivity.

Is there any pain when you push or press hard against the root canal-treated tooth? If there is still no relief, then it is advised to get root canal treatment done on the last tooth as sometimes it is difficult to understand which tooth is responsible for our discomfort.

Thank you.

Along with the pain in your cheek and headache, do you have any congestion in your sinuses or inside your nose? There might be a slight chance of the spread of infection through the sinuses.

Thank you.
