What causes dark spots on the tongue?
Patient: I have two faded dark spots on right side tongue an left side, I’ve seen oral surgeon who says he isn’t worried because it’s not raised or hard an for me to keep eye on more than a couple dentist called them Amalgam tongue from all my silver fillings as well as over production of melanin, shld I be more concerned I’am arching them constantly. Doctor: Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Dark spots on tongue that are not raised can be Amalgam tattoo if you have amalgam fillings while it can also be black hairy tongue, infection, hyperpigmentation etc..So first of all you should start cleaning your tongue with a tongue scraper.Also drink plenty of water.Eat hard foods like carrots, apples etc.Maintain a good oral hygiene.To be confirmed that it is nothing serious you should once get it checked  by an Oral Surgeon.You can also send me pictured of the tongue spots so that I can advise you better..Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Honey Arora
