Sounds more like chemical sensitivity! Are they organic or store bought? Grog

Not so much allergic, but there is an imbalance there. It means your body type doesn't do well with a lot of fruit acids and Vitamin C. Are you taking in a LOT of tropical or citrus fruit servings and Vit C supplements each day? I have friends who cannot drink OJ or they get cankor sores, it's about the same thing.

Consider changing your toothpaste too. If it suds up a lot, the additive that creates suds is murder on the delicate balance of the mucous tissues. Switch to a baking-soda based toothpaste.

Hope that helps! :)
