I had my right bottom wisdom tooth extracted due to an abscess on June 18th. They had to remove cheek muscles and tissue due to pus eating at it. Also they put in a tube down thru my neck to aid in the drainage of the pus. I still have trouble opening my mouth wider then an index finger but am doing my mouth exercises regularly. However now after the initial pus drained I'm beginning to get that taste in my mouth again particularly after the exercises. Could this mean it has gotten infected again or is it still old pus squeezing out nearly two months later.
