Had an infected tooth for months and was removed 2 months ago what's the longest amount of time it will take for lymph node under jaw to normal?

Within 2 weeks: if there is no residual infection at the extraction site, then the lymph node usually normalizes in very short time but typically within 2 weeks. I Rx that you get the lymph node checked if it persists.

See your dentist: Depending on the severity of your infection, it could take several months. See your dentist to make certain your healing is going well, that you do not have a residual infection.

Lymph node.: If it is due to the tooth infection, it should disappear a few weeks after the infection totally clears up. However, it can be something else too. So you need to see your own physician as soon as possible.

Depends: Primary function of lymphatic system is to eliminate toxins, waste, infections. Lymphatic fluid is in ultrafiltrate of the plasma in the blood. Persistent dental infection, such as periapical abscess, erosive gingivitis, which nuchal infection can cause chronic lymph node enlargement. Enlarged lymph nodes usually returns to normal once the infectious etiology has resolved.
