I have an awful rancid taste in my mouth and yellowing of my tongue x6 days after wisdom tooth removal. not being made better by salt rinses. normal?

Dry Socket ?: Infection ? Either way, rancid taste and yellow tongue is not normal. Please see your oral surgeon for further guidance.

Post wisdom teeth: Have you been brushing your teeth and tongue? What is your pain level? Contact the extracting dentist or oral surgeon for the best answer to your problem.

No: Not normal. May be Thrush, a fungal infection. Please return to your Oral Surgeon for diagnosis and Rx.
