Mouth Ulcers are simply an area of tissue erosion on the surface of the skin. These can result from stress, the time of the month (for women), a weak immune system, being too rough with your toothbrush, jagged teeth, chewing your cheeks continuously, burning from a hot drink or a deficiency in vitamins B12, iron, folic acid, zinc and vitamin C.

Another treatment option is to gargle a mixture of sage tea with 2 drops of tea tree oil mixed in warm water. Eat more red and yellow vegetables, wholegrain breads and cereals, citrus fruits, nuts, eggs, lean meat and seafood.
