Any periodontist here? 47? do i ext 47?

From your description, it seems that you have been experiencing severe pain in the back and distal side of your second molar tooth (#47). It's essential to follow the advice and recommendations of your dental professionals, including your dentist and endodontist, as they have examined you and have access to your dental history and X-rays. Regarding the X-ray, the appearance of darkness on the distal side of the tooth may indicate different things, such as: Infection: A dark area around the root can indicate the presence of an infection or abscess. Cavities or Decay: Dark areas could also indicate cavities or tooth decay. Bone Loss: Periodontal disease or gum issues could lead to bone loss, which may be visible on the X-ray. Artifacts or Image Quality: Sometimes, X-rays may have artifacts or variations in image quality, leading to areas appearing darker. Given that your endodontist suggested a root canal due to inflammation seen on the CBCT scan, it's possible that there is an issue with the tooth that requires treatment. Root canal treatment is often recommended to address infection or inflammation within the tooth's pulp, which can relieve pain and save the tooth. If you have concerns or doubts about the recommended treatment, you can consider seeking a second opinion from another dental professional. They can review your X-rays, examine your tooth, and provide their expert opinion on the best course of action for your situation. Remember that dental conditions can be complex, and it's essential to work closely with your dental team to address any ongoing pain or issues with your teeth. Prompt treatment can help prevent further complications and promote better oral health. Please consult with your dentist or endodontist to discuss your concerns and to determine the most appropriate treatment plan for your specific case.

Get an EPT done for 47 and see if there's a need for RCT

Hi. Go for deep scaling and root planing

The gum around the tooth is inflamed. Also, the distal side has a deep pocket and the food is getting impacted and has resulted in  caries.

This tooth needs root canal and deep curettage around the tooth.

Medication and taking a soft diet is recommended to get immediate relief. Visit to the dentist is required.
