Hello I share your concern Looking at your description this might be caused by poor oral hygiene, Nutrional deficiency like B complex and vitamin C or an infection or inflammation of oral cavity I would like more details like habit of smoking or ingestion of hot or spicy meals. In my opinion you should take cold or icy food like ice creams for an soothing effect you should take multivitamin like B complex and folic acid if it doesn t improve with that the you should see a doctor for physical examination and a course of antibiotics if need be Hope this helps you Best wishes
