Medical Experts

I have GBS and undergone privigen treatment in mid October of this year. In the last few weeks I have had a loose molar which had to be removed when I saw my dentist. There was no excessive plaque decay or gum disease of note. Since then, I have noticed another molar on the same side of the mouth come loose. These are healthy teeth, is there a relation to my condition or the treatment I underwent? I am a 52F with no other medical conditions.
