My tongue has an orange coating a couple of days after a tooth extraction. i did not eat or drink anything orange. should i be concerned?

No worries: Not to worry. Likely some slight remnants of the bleeding . Try scraping your tongue with floss or your toothbrush. Easy way is to stick your tongue way out and then put the brush on top of tongue near the back and then pull your tongue back in. Better than shoving the brush way back in to the throat area. If it does not clear up , see the surgeon. Good Luck.
