I had to go and check because I didn't know the answer for mangoes (although it seems like it should be high in malic acid). Turns out that it is, yeah.
One thing that's only just occurred to me is that toothpaste is an alkali (for obvious reasons; to counteract acidity and erosion). When an alkali and an acid react there's usually a bubbling, fizzing, effervescing effect because most often one of the products of the reaction is a gas. Thinking about the structure of malic acid, it's pretty much guaranteed to be carbon dioxide.
I think that's what's happening. The remnants of your toothpaste are undergoing a chemical reaction with fruit acid. Nothing much to worry about. :)
Is it normal my gums ache when i eat certain fruits?

It's never strawberries, or any berries for that matter. I'm also usually fine with most citrus fruits. But mangos also do it too

I have read somewhere that it may be a food allergy. My symptoms seem to be mild but they do fit exactly.
