10 Causes of Canker Sores on the Lips and Smart Ways to Treat Them
Canker sores on the lips are a common problem that many people experience. The causes of canker sores on the lips can vary, from lifestyle factors to certain medical conditions.
This condition is generally not dangerous. Appearing as a round white lesion, a canker sore only causes a stinging sensation and pain, especially when the lesion is touched or rubbed. Even so, its presence is very bothersome because it often makes sufferers have difficulty speaking and eating.
What are the triggers for the appearance of these canker sores, and how can they be effectively treated? Read the full review in the following discussion!
What Causes Canker Sores on the Lips?
So, it turns out there are several culprits behind the sudden appearance of this uninvited guest on the lips:
1. Habit of Biting the Lips

For some people, biting their lips is a reflex that appears when they are nervous. This condition is generally experienced by children or people with psychological problems.[1]
This habit will trigger a canker sore when the biting activity is done too hard, injuring the delicate lining of the mouth. The resulting wound will later develop into a canker sore.
2. Use of Toothpaste Containing SLS

The SLS composition in toothpaste is indeed beneficial, not only providing abundant foam, but also helping the toothpaste spread more easily in the mouth. However, using a high dose can irritate the mucosal lining of the mouth, thus stimulating canker sores on the lips.[2]
3. Negative Reaction from Taking Medication

Who would have thought that the medication you take to cure an illness could also bring a little "friend" called a canker sore?
Yes, several types of medication, especially for the treatment of chronic diseases such as diabetes, angina pectoris, rheumatoid arthritis, and osteoporosis, can trigger the appearance of canker sores on the lips.[3]
4. Inadequate Intake of Vitamin B12 and Zinc

Research shows that 34.4% of patients with recurrent canker sores had anemia, likely caused by a deficiency in vitamin B12, folate, or iron.[4] This indicates a significant relationship between a deficiency in these vitamins and the appearance of recurrent canker sores.
5. Friction with Braces

For braces users, canker sores may not be strangers. Pressure from brackets, wires, archwires, and the long wire of the braces can trigger wounds on the inner lips, which eventually develop into painful canker sores.
6. Hormonal Changes

For women, menstruation does not only bring pain and abdominal cramps, but also the potential for canker sores. This can happen because a surge in estrogen and progesterone hormones makes the oral tissues more sensitive. As a result, even slight friction or impact can injure the lips and trigger a canker sore.
7. Oral Cancer

Although canker sores are generally not related to cancer, sometimes a canker sore can be one of the symptoms of oral cancer.
Common canker sores usually appear as lesions with reddish wound borders that feel painful or sore. Meanwhile, canker sores caused by oral cancer are characterized by lesions that do not heal, a small lump felt under the lesion, and no stinging sensation.
8. Lupus

Canker sores can also be one of the signs of lupus. Usually, canker sores caused by lupus are red with white edges and often appear on the roof of the mouth, the inside of the cheeks, and the lips.
9. Calcium Deficiency

If the body lacks calcium, the function of the oral mucosa can be impaired. As a result, parts of the mouth become more sensitive to various external stimuli, so even slight friction or impact can trigger the appearance of canker sores. Not only that, this condition can also worsen existing canker sores.
10. Internal Heat

The presence of canker sores can also be a sign that your body is experiencing internal heat. Internal heat itself can be caused by consuming foods that are too oily or fatty, not drinking enough water, and intense activity in a polluted environment.
