Canker Sores And Vitamin Deficiencies

The pain and discomfort caused by canker sores make them more problematic than cold sores, even though these are more visible. Sometimes the pain is so intense that eating and talking become difficult tasks. Aphtous ulcers, as they are also called, are more likely to appear on female patients and those who have a genetic tendency to get them. It’s possible that if you frequently have canker sore outbreaks, you have a vitamin insufficiency that needs to be taken care of by your doctor.

Canker Sores And Vitamin DeficienciesUnderstanding Mouth Sores

All soft tissue in your mouth can become affected by canker sores. They develop on the gums, tongue, lips and insides of the cheeks. Unlike cold sores, they don’t show up on the external parts of the lips.

Canker sores are usually rather small, most of them less than ½ inch in size. They are round or oval, with a white or yellowish centre, and can be very bothersome, turning simple tasks into serious challenges. Injuries to the mouth, bacteria, a weak immune system and stress are some of the most common causes of these lesions.

Vitamin Insufficiencies

Your tendency to develop mouth sores may go up if you lack vitamins, especially B complex vitamins such as B-3 or niacin, vitamin B-9 or folic acid, and vitamin B-12. In order to maintain healthy skin, niacin is very important, as well as being involved in the production of hormones, aiding the nervous system and food digestion and break down. Even a mild insufficiency can result in these lesions appearing in your mouth. Vitamin B-12 and folic acid are vital in the production of blood cells so your risk of developing canker sores increases if you lack these nutrients. It’s important to know that these deficiencies can be a sign of a bad diet, which may put your immune system at risk.

How To Recognize Vitamin Deficiencies

Canker Sores And Vitamin DeficienciesBesides mouth sores, a vitamin deficit of both folic acid and niacin, can cause inflammation and soreness on the tongue and in the mouth. Gingivitis, which is the inflammation of the gums, can be the result of a folic acid deficiency. Not to mention the effects it can have on your gastrointestinal system and your general state of mind. If you present symptoms like feeling weak, balance problems, or feel your limbs tingling, it’s possible that you have a vitamin B-12 deficiency.


Mouth sores that are occasional and minor usually don’t need medical attention. They normally disappear on their own within a week or two. You can use prescription medicine or home remedies to help with the healing process, and some of them might work rather well in your case.

You can also avoid irritants, like eating food that is spicy or salty, in order to stay clear of painful situations. However, if the cause of these lesions is a vitamin deficiency, that means that you will probably develop them more often than others and it would be advisable to consult your doctor to get a prescription treatment for your episodes. You’ll probably need to get tested to determine if and where your insufficiencies lie and take action from there.
