You may be very ill: KristofferL, if you have no GUM issues or painful teeth, this could mean a buildup of toxic chemicals in your system coupled with dehydration. Please drink LOTS of water, try carefully brushing your tongue, avoid all alcohol and OTC meds,, and see a doctor very soon if it doesn't clear up. If you DO have dental or gum issues, these should be evaluated and treated by a dentist or other provider.
