I found the main problem was the mint flavourings. My solution was a children’s toothpaste from Wilko that is strawberry flavoured.
It’s definitely the mint that caused my issues. Obviously I have become increasingly concerned about halitosis because of it (mouthwashes and most chewing gum is obviously out of the question, again because of the mint). Because saliva is so important and I have a degree of xerostomia, I’m delighted that Starburst do chewing gum that either has no mint or it’s so mild that I have no I’ll effects from it. I considered buying some bubble gum yesterday, but I have some very loose teeth at the mo & it’s not worth the risk!So I can produce more saliva, protecting my mouth & teeth, without pain. I use the strawberry children’s pastes at night (Sainsbury’s or Morrison’s own brands), simply as a cheaper alternative to the Calendula toothpaste; I use Tepe interdental brushes every day - I aim for twice a day, but definitely at night; every couple of days I use diluted Corsodyl original mouthwash (I need the local anaesthetic for this) and once or twice a week I’ll use a whitening toothpaste, again with local anaesthetic. Still settling into a routine but so far so good.
