pj,
Do you take Vitamin C? It really helped when I had my fillings out and I even had a vit C IV with each session.
If you have some I would keep up with large (whatever that is for you) doses for the next couple of days. ( I take 2-6 grams a day, so I took 2 grams several times a day.
Also Glutathione supports the liver which has to detox everything. I was told to take 500mg every couple of hours as needed.
Take care, be good to yourself, stay away from stress and just take it easy,
