Tongue ulcer


Hello doctor, I have an ulcer on my tongue that has lasted for more than two weeks.
It is completely painless now, and I don't feel any wound, but there is still a white shape (approximately 0.1 to 0.2 cm in length and width) which is the white part of the ulcer.
Does this indicate that the wound has not yet healed?

Encore, 30~39 year old female. Ask Date: 2016/04/26

Dr. Zheng Jueyi reply Otolaryngology


Hello: It should be the tissue after wound healing.
If there is no pain, you can observe it for now.
Wishing you safety and health.
Sincerely, Dr.
Cheng Jue-Yi, Director of the Department of Otolaryngology, Taoyuan General Hospital, Ministry of Health and Welfare.

When dealing with tongue ulcers, it's essential to understand the healing process and what signs to look for. From your description, it seems that you have a tongue ulcer that has been present for over two weeks. The fact that it is no longer painful is a positive sign, indicating that the ulcer is likely healing. However, the presence of a white area where the ulcer was located suggests that the healing process is still ongoing.

Tongue ulcers, also known as canker sores or aphthous ulcers, can be caused by various factors, including stress, certain food sensitivities, vitamin deficiencies (such as vitamin B12, folate, or iron), and even mechanical trauma (like biting your tongue). They typically present as painful, shallow sores on the tongue or inside the mouth, and while they can be uncomfortable, they usually heal on their own within one to two weeks.

The white area you are observing is likely a result of the healing process. When ulcers heal, they often form a whitish or yellowish coating, which is part of the body's natural response to tissue repair. This coating is made up of dead cells and immune cells that have gathered to help protect the area as it heals. While the ulcer may no longer be painful, the presence of this white area indicates that the tissue is still in the process of regeneration.

In terms of what to expect moving forward, here are some key points:
1. Healing Timeline: Most tongue ulcers will heal completely within 1-2 weeks. Since yours has been present for over two weeks, it is still within the normal range for healing, especially if it has become painless.

2. Signs of Healing: The reduction in pain and the formation of a white or yellowish coating are good signs. You should also look for a gradual decrease in the size of the ulcer and a return to normal color in the surrounding tissue.

3. When to Seek Medical Attention: If the ulcer does not show signs of improvement after three weeks, or if you notice any new symptoms such as increased pain, swelling, or the development of additional ulcers, it would be advisable to consult a healthcare professional. Persistent ulcers can sometimes indicate underlying health issues, such as autoimmune conditions or infections.

4. Self-Care Measures: To support healing, consider maintaining good oral hygiene, avoiding spicy or acidic foods that may irritate the ulcer, and staying hydrated. Over-the-counter topical treatments may also provide relief if you experience discomfort.

5. Underlying Causes: If you frequently experience tongue ulcers, it may be worth discussing with a healthcare provider to rule out any nutritional deficiencies or other health conditions that could be contributing to their recurrence.

In summary, the white area you see is likely a normal part of the healing process, and the absence of pain is a positive sign. Continue to monitor the ulcer, and if it does not heal completely within a few more weeks, or if you have any concerns, do not hesitate to seek medical advice.
