Brush: First thing to try is to brush your tongue. If this does get rid of the problem see your dentist or physician.

Hairy tongue: May be caused by the 2 antibiotics that you took, neither of which are the antibiotics of choice for most oral infections. You now have a collection dead cells on your tongue that are harmless, and that can be brushed away over a few days. See your Dentist for help, and avoid dosing yourself with meds that are not specifically prescribed.
