What causes two white lines on both sides inside the mouth, and what should be done?

Generally, the presence of two white lines on both sides inside the oral cavity may be caused by reasons such as linea alba, white edema, oral leukokeratosis, oral lichen planus, oral ulcers, and others. The appropriate treatment depends on the specific underlying cause. If discomfort occurs, timely medical consultation is recommended. Detailed analysis is as follows:

1. Linea Alba: Linea alba refers to white keratotic lines formed on the oral mucosa due to long-term friction from teeth during chewing. They typically appear between the upper jaw and the buccal mucosa, but may also occur on both sides inside the mouth. These lines are considered a normal physiological phenomenon, generally asymptomatic, and require no special treatment.

2. White Edema: Prolonged smoking or alcohol consumption may damage the oral mucosa, leading to ulcers and white edema. Additionally, oral mucosal trauma, such as burns or bites, and herpesvirus infections may also cause white edema and the associated symptoms. Patients may use medications such as Bingbor powder or watermelon frost throat lozenges under medical guidance, quit smoking and alcohol consumption, and maintain good oral hygiene.

3. Oral Leukokeratosis: This condition may be related to poor oral hygiene,不良 oral habits, anemia, diabetes, and other factors. It is primarily characterized by localized white keratotic patches or plaques on the oral mucosa caused by long-term mechanical or chemical irritation. The aforementioned symptoms may also appear in this condition. Usually, removing the irritants can lead to gradual thinning or resolution of the lesions.

4. Oral Lichen Planus: This is a common chronic inflammatory disease that may be associated with psychosocial factors, endocrine factors, and others. It is characterized by white or grayish-white striations or plaques formed on the oral mucosa. These striations may appear on both sides of the oral cavity, accompanied by mucosal roughness and congestion. Patients may use medications such as retinoic acid capsules or compound glycyrrhizinic acid capsules under medical guidance for treatment.

5. Oral Ulcer: Oral ulcers are common round or oval painful areas on the oral mucosa, which may be caused by psychological factors, immune factors, digestive system diseases, and often accompanied by redness and inflammation. When ulcers occur on both sides of the oral cavity, they may form white line-like marks. Patients may rinse with mild salt water to maintain oral hygiene and use medications such as oral ulcer powder or stomatitis clearing granules under medical guidance for treatment.

In daily life, it is important to maintain good living habits and avoid consuming spicy and irritating foods, such as pepper, chili, garlic, etc., as they may hinder recovery.
