Re: Am I allergic to toothpaste ?
You could try using lip balm before brushing your teeth. I have heard from my allergist about someone that was allergic to toothpaste so it is actually not unheard of!!! You could try changing brands, do you use anything specific right now? Perhaps if there are extra whiteners, breath fresheners, baking soda, etc. it could be more irritating. Make sure that you rinse well afterwards if you think that your toothpaste is burning your lips.
