@jasminerdh: If you notice any of these signs, you may need to switch toothpaste! Sodium lauryl sulfate (SLS) is a common ingredient in over-the-counter toothpaste. SLS is a detergent that makes toothpaste lather and foam while brushing. However, for those with an allergy, it may cause irritation to the gum tissue and around the mouth. Switch to an SLS-free toothpaste ASAP if you think you’re allergic to your toothpaste.
