Thanks for sharing your concern.
I can understand your agony very well.
please do not be worried now ,it will recover soon as the body has its own mechanism to get rid of undesirable substances.
It appears the taste,smell and appearance of composites used was disagreeable to your system and thus developed an allergic response
.Might be of poor quality.
Since you have got it removed and also visited physician,i feel it should recover now.
Please wait and watch for a week more before you take further decision .
Meanwhile do warm saline rinses and do not use any foreign(new) substances like fillings in your mouth.
Hope it helps.
