I got a reline on my temporary upper two days ago and the chemical taste is so bad that I cannot keep it in my mouth. I’ve soaked it, rinsed with mouthwash, etc and nothing is lessening this terrible taste. Is this normal? What can I do to get rid of it? Why on earth would a company make something that has to stay in someone’s mouth taste like a harsh cleanser?!? This process is just too aggravating sometimes.
