I fell asleep on the couch, laying on my stomach. When I woke up, I brushed my teeth and used my tongue scraper, per usual. Then I noticed two (almost symmetrical) dark spots on the front of my tongue. Is it possible my two front teeth were pressing on my tongue, and caused these spots? They're not raised, and they don't hurt. I had cinnamon Altoids and quite a bit of hot sauce this evening (not an issue in the past; I'm a hot-sauce lover).
Thanks for your help,
AJ
