Mouth ulcers are small, painful sores that sometimes appear on our tongue, inside of our lips, or on our cheeks. Here are the main reasons behind this condition, which causes severe burning when we eat hot or spicy foods:
Vitamin and mineral deficiency: The most important cause of mouth ulcers is a deficiency of vitamin B-complex (especially vitamin B12 and folic acid), iron, and zinc in the body. It is more common in people who do not receive proper nutrition.
Stomach upset and acidity: There is a close relationship between our digestive system and oral health. Mouth ulcers often occur as a symptom in people with chronic constipation, gas trouble, acidity, and peptic ulcers.
Minor injuries in the mouth: Accidentally hitting the toothbrush while brushing your teeth, accidentally cutting your cheek or tongue while eating, and constantly rubbing your teeth against the inside of your mouth can cause minor cuts to develop into mouth ulcers.
Severe mental stress and lack of sleep: Mouth ulcers are common among those who are in the heat of exams or under excessive pressure at work. Severe stress and lack of sleep can temporarily reduce the body’s immune system and cause ulcers.
Chemicals in toothpastes: Sodium lauryl sulfate (SLS), a chemical found in some toothpastes and mouthwashes, can dry out the inside of the mouth in some people and cause mouth ulcers.
