I recently booked and paid for a set of 6. It was non refundable. However, I couldn't even bear the pain for 5mins of the first session. I have metal in my teeth and jaw due to an accident and it was basically conducting. The pain was intense and I nearly passed out.
I want to ask if this is a known issue or common side effect? Would it always be like this or are there different ways of doing it? I'm gutted to have spent £600 but more gutted not to be able to have it done.
