Thanks fro using Health Care Magic. Read your query. The white spot in the mouth suggests an apthous ulcer ,which is usually stress related. I would advice you to apply mucogel/dentogel ointment on it two or three times daily for few days or till the symptoms reduce. Stop worrying and have a healthy and nutritious food.Avoid spicy and too hot foods. If persistent consult your local dentist. Hope this was helpful. Thanks and regards.
