If you frequently have mouth ulcers, it could be a sign of a vitamin B12 deficiency. You need this vitamin to keep your nervous system healthy and to make red blood cells, and to release energy from food. When you don’t receive enough vitamin B12, your body produces abnormally large red blood cells that don’t function correctly. Vitamin B12 deficiency is often associated with anaemia, and it can cause symptoms that include mouth ulcers.
Mouth ulcers can be very painful but usually clear up on their own within a week or two. They aren’t usually a sign of anything serious, but they can be unpleasant. Other signs that you may be deficient in B12 include a lack of energy, having a sore and red tongue, or feeling extremely tired. If you are anaemic, you may feel faint or breathless, will have a loss of appetite, heart palpitations or weight loss. It is important to get a proper diagnosis and treatment for this deficiency because some problems caused by this condition can be irreversible.
Also, if you do have a mouth ulcer that fails to heal properly after a couple of weeks, please get in touch with our dental team. We can check it just to make sure it isn’t caused by another condition.
