Did the dumbest thing yesterday, rinsed for 5 min or longer with lemon juice concentrate to see if it would whiten my teeth. Burned like hell and now teeth are still gritty. Can you destroy the enamel completely one time? I'm terrified then of course I brushed, thinking to take it back off. BAD MOVE. You never brush after eating ANY acid food for one hour. Only rinse with water. If anyone can shed light on my nightmare I'd love you to death...so worried and scared.
