My DS’s first major sudden onset of OCD at age 8, happened within 48 hours of dental work. The conventional psychiatrist he first saw said it was possibly triggered by the Nitrous Oxide. Apparently it can deplete vitamin B6 or B12 (can’t remember which). She threw that theory out the window after his labs showed no B Vitamin deficiencies.
Years later, another PANDAS mom informed me that dental work is a common trigger for PANS/PANDAS. It can unleash hidden bacteria. Now my DS starts an antibiotic a few days before dental appointment (even cleaning), and continues for 2 weeks after appointment.
I’ve been skipping the fluoride treatments for him. The dentist disagrees, but I don’t want to take any chances.
