@serita If I remember correctly, the reaction to the implant started within a month or 2 of when it was placed and she recovered when it was removed. I think we are all different in our timeline of developing a problem, it may happen to you sooner than someone else. It sounds to me like your dental surgeon does not know the source of your pain.

What I think about as a possibility for your head pains may be related to spine/skull alignment. You may have had your neck in an unstable posture while the dental work was being done, and if you are prone to muscle spasms it can create a painful situation that lasts when bones are not in the proper place which stretches muscles and causes pain. I am a cervical spine surgery patient and prior to my spine surgery, I had muscle spasms changing my spine alignment because it independently rotated or twisted vertebrae which caused lots of pain, bad headaches and vertigo when C1 and C2 were affected. Getting everything realigned in therapy resolved it, and after spine surgery corrected the disc problem, everything calmed down. You might want to see a physical therapist for evaluation. This can cause a lot of headaches.

Here is a link that can explain some of the issues. The article describes a lot of posture related problems that lead to instability of the atlas and axis which are the top 2 vertebrae (C1 & C2) that support the skull. He describes cervical "hinging" which is bad forward slouching posture that sticks the neck out like we do when looking at computer screens. Here is a quote from https://mskneurology.com/atlas-joint-instability-causes-consequences-solutions/

"Occipital neuralgia can be devastatingly painful, in similar fashion to trigeminal neuralgia (which you can read more about in my TMD article), and may cause severe neuralgic pain, radiating into the posterior neck and head. It is sometimes described as an electric shock, a sharp and stabbing pain."
