What are the symptoms of ulcers on the inside of the lips

Ulcers on the lips can be divided into the inside and outside of the lips. In general, ulcers on the inside of the lips are the most common. There are many reasons for ulcers on the inside of the lips, but the most common ones are probably caused by excessive heat in the body and accidental bites while chewing.

1. Mild oral ulcers:

This type of mouth ulcer causes severe burning pain, especially at the tip of the tongue. In the early stage of the disease, a slightly larger area of ​​congestion, a needle-like area or sensitivity will appear on the affected area. Within a short period of time, a small shallow round or oval ulcer with clear boundaries will form. The diameter is generally around 2 to 4 mm, and the number is generally 2 to 3. This ulcer is self-healing but can recur.

2. Periglandular oral ulcers

Periglandular ulcers are also known as giant ulcers. They are the most serious type of oral ulcer symptoms. They often occur on the inner side of the lips and the mucosa of the corners of the mouth, and can also occur in the soft palate, palatoglossal arch and other parts. The initial stage of the disease is the same as that of mild oral ulcers, but it will occur individually. The diameter of the ulcer will gradually expand and develop deeper into the mucosal glands. The disease usually lasts a long time and will leave scars after healing. In severe cases, it may also cause tissue defects or deformities.

3. Herpes-like oral ulcers

This type of oral ulcer is also called stomatitis-type oral ulcer. Its symptoms are very similar to those of mild oral ulcer, but the number is large, and the mucosal congestion is obvious and widely distributed. In addition to severe pain in the affected area, there are also symptoms such as local lymph node enlargement, fever and headache.

4. Behcet's syndrome

This type, also known as oculo-oral-genital triad, is a systemic disease with recurrent attacks and damage to the skin, eyes, mouth, and genitals, as well as the nervous system, cardiovascular system, and joints.

5. Traumatic ulcers

According to the duration of mechanical stimulation, it can be divided into persistent and non-persistent stimulation factors. Persistent mechanical stimulation, such as residual crowns, residual roots, sharp edges, sharp tooth tips, and poor restorations formed in the oral cavity due to caries. Non-persistent mechanical stimulation factors such as stimulation from hard and brittle foods, accidental bites while chewing, injuries from brushing, improper use of instruments by dentists during treatment, etc., can all cause trauma to the mucosa and form ulcer lesions.
