Lingual Marginal Glands: White Lines and Treatment Options - Otolaryngology

Share to:

Sublingual gland


There is a white fine line about one centimeter long on the edge of my tongue that has been present for about a year.
It is not painful or itchy.
If it is leukoplakia, should I immediately undergo laser removal, or should I observe it for a while? After laser removal of oral leukoplakia, will the healing tissue always appear white? It has been over three months, and it is still white.

Hello, if there have been no significant changes or pain for a year, it is commonly considered a normal phenomenon.
However, if you are concerned, it is advisable to seek medical evaluation to determine whether it is leukoplakia or normal tissue changes.
Wishing you safety and health.
Sincerely, Dr.
Cheng Jue-Yi, Director of the Department of Otolaryngology, Taoyuan Hospital, Ministry of Health and Welfare.

When it comes to the presence of a white line or patch on the lingual marginal glands of the tongue, it’s important to approach the situation with a thorough understanding of oral health. The white line you describe could be a manifestation of several conditions, including leukoplakia, which is a term used to describe white patches that can appear on the mucous membranes of the mouth, including the tongue. However, it’s crucial to note that not all white lesions are indicative of a serious condition.

1. Understanding the White Line: The white line you’ve observed on the edge of your tongue could be due to a variety of factors. It might be a benign condition, such as frictional keratosis, which occurs due to chronic irritation, or it could be a sign of a more serious condition, such as leukoplakia or lichen planus. Given that it has been present for about a year without any pain or discomfort, it may not be an urgent concern, but it should still be evaluated by a healthcare professional.

2. When to Seek Treatment: If the white line is suspected to be leukoplakia, it is essential to monitor it closely. While some leukoplakic lesions are benign, others can potentially harbor dysplastic changes, which could lead to oral cancer. Therefore, it is advisable to have a biopsy performed to rule out any malignant changes, especially if the lesion persists or changes in appearance. If the biopsy indicates that the lesion is benign, your healthcare provider may recommend a watchful waiting approach rather than immediate intervention.

3. Laser Treatment Considerations: If a decision is made to remove the lesion via laser treatment, it is important to understand the healing process. After laser excision, the area may initially appear white due to the healing process, which involves the formation of new tissue. This white appearance is often temporary, and the tissue may gradually return to a more normal color as it heals. However, in some cases, the area may retain a lighter appearance due to the nature of the healing tissue or scarring.

4. Post-Operative Expectations: If you have undergone laser treatment and the area remains white after three months, it is advisable to follow up with your healthcare provider. They can assess the healing process and determine if the appearance is within normal limits or if further intervention is necessary. It is not uncommon for post-operative sites to take several months to fully heal and regain their normal color.

5. Monitoring and Follow-Up: Continuous monitoring of the lesion is crucial. If you notice any changes in size, color, or texture, or if you develop any new symptoms such as pain or discomfort, it is important to seek medical advice promptly. Regular dental check-ups can also help in monitoring oral health and identifying any potential issues early on.

In summary, while the presence of a white line on the tongue may not be immediately alarming, it is essential to have it evaluated by a healthcare professional to rule out any serious conditions. If treatment is necessary, understanding the healing process and what to expect post-treatment is vital for your peace of mind and overall oral health.
