"Prevention: It is best to avoid causes of dentinal hypersensitivity. Acidic food and drinks can damage tooth enamel. From most acidic to least, some of the foods and drinks to use cautiously include ginger ale, limes/lemons and their juices, wine, cranberry sauce, coffee, vinegar, pickles, cola and citrus-based drinks, apples, rhubarb, raspberries, root beer, relish, strawberries, fruit jams/jellies, peaches, sauerkraut, blueberries, pineapples/pineapple juice, cherries and grapes. It is especially important not to brush right after ingesting these foods, because they strip away the tooth's protective layer, and you will be brushing naked enamel, which is more prone to damage."

Above is from a google search. I have very senstivie teeth too.
Mangos are not mentioned LH so your good to go and maybe you have been saying Hillary too much!! Perhaps a changing your word for a while may help!
I use Tea Tree Toothpaste. It helps a lot.
