Please post a clinical picture of the tongue so that we can provide a more rational opinion. On a conservative note, try to make sure that your tongue is clean by using a toothbrush to scrape the top part of the tongue. Do not use a tongue cleaner whether plastic or metallic or wooden as it can do more harm than good. Maintain good level of hydration and if the symptoms don't subside within 4 to 5 days please see a dentist for a proper clinical evaluation. Regards
