Can accidentally or unknowingly swallowing tiny particles of breaking teeth cause dry throats, hoarseness, itchiness, or other back-of-the-throat irritated allergy symptoms? I ve been experiencing what I thought was overly dry air and pet allergies , but I noticed a molar in the back of my mouth has some surface breakage and wonder if that s been the main cause of my irritated throat instead. I ve had no pain, mucus, or sore throats - just regular irritation.
