B vitamins are very important for oral health. When there is a deficiency of vitamins B1, B2, B3, B6 and / or B12, problems such as dry mouth and ulcers, tongue inflammation, and lip inflammation are likely to occur. This is stated in a study published in the Journal of the Academy of General Dentistry.
With a lack of B12, angular cheilitis may occur. This condition is characterized by inflammation of one or both corners of the mouth. In most cases, redness, cracks, peeling appear in these areas, and soreness of the lips as a whole can be observed. With a lack of vitamin, white crusts and bleeding wounds also form on them, and the lips may itch.
Lips chapped due to deficiencies in vitamin B12 and other B vitamins, bacterial or fungal infections, and exposure to cold. Most often, cracks on the lips heal on their own, but if they do not go away for a long time, you should consult a specialist.
