Is any infection in jaw bone? Infected?

Based on your description, it appears that you have been experiencing severe pain in the gum area of tooth #47, along with pain in the #48 region. You mentioned that #46 was previously removed due to pain and an infection was found at the bottom and jaw bone during the extraction, even though it did not show on the CBCT scan. Since you are now experiencing severe pain in tooth #47, it is important to consult with your dentist or oral surgeon for a thorough evaluation. They will assess the condition of the tooth and surrounding tissues, including the possibility of infection or other underlying issues. They may recommend further imaging or diagnostic tests to gather more information. Considering the history of infection and the persistent pain, extraction of tooth #47 might be a potential option to alleviate your discomfort. However, only a dental professional can provide a definitive diagnosis and treatment plan based on a comprehensive evaluation. It is advisable to seek prompt dental care and communicate your concerns and symptoms to your dentist. They will guide you through the appropriate next steps, which may include further diagnostic tests, consultation with specialists, or extraction if deemed necessary. Addressing the issue promptly will help in resolving the pain and ensuring the overall health of your oral structures.
