Has anyone ever used arm & hammer toothpaste it's the advance white one and had an allergic reaction? ? I started using it about a week ago an my tongue felt a bit funny at the front like I had burnt it then over the next few days it went a bit patchy my tongue & weird just didn't look right and in the middle but towards the back it's a bit lumpy. I think the last time I used it was Sunday morning. ..It doesn't hurt but it's not gone back to normal yet I'm only assuming it's the toothpaste.
