Hi Dr.Sher,
Thank you for taking the time to answer my question.

A month prior to my FET I had dental bone graft placed. I took a full course of antibiotics and the healing was uneventful.
Following month, my FET failed.
Could the bone graft activated/elevated my immune response causing the embryo implantation to fail?
Should I do an immunology workup before next FET or given enough time, the immune response would become normal?
My dentist could not answer this in regards to implantation failure possibility.

Thanks in advance.
