Can teeth extracted in teens cause nerve damage in 40s? teeth surrounding extracted teeth on one side throb/ache periodically, worse during migraine.

Unlikely: What is more common is that your Migraines are actually (caused or triggered by) Sinus headaches (either acute/acute on chronic sinusitis)- Very common for sinus inflammation to cause "referred" dental pain. It is how are Facial Nerves are "wired". Worth Having your Doctor look into it.

Nope: Extraction of teeth rarely if ever result in nerve damage, and if damage occurs it will be known immediately, not 20+ years later. When was your last dental checkup with radiographs and a cleaning? You may be grinding, you may have gum disease... why guess? See a local dentist to be sure.

It is not possible: This is a facial migraine. Unfortunately, because of a lack of knowledge about facial migraine, many patients are seen by a number of clinicians before being diagnosed with the problem. They often undergo dental treatments such as endodontic therapy, apicoectomy and even extraction in a vain attempt to relieve the pain.
