7. Oral Ulcers
Oral ulcers are lesions that develop in the mouth, especially the base of the gums. These small sores are usually called canker sores.
There are many causes of oral ulcers, which include biting the inner cheek, allergy to certain foods, brushing teeth aggressively, changes in hormonal levels, deficiencies in certain vitamins, bacterial infections, and other diseases. These oral ulcers appear as small, round lesions, which generally heal without any scars.
