Oral Ulcers: Healing and the Impact of Scarring - Otolaryngology

The oral ulcer has healed, but it has left a scar?


I have slightly protruding front teeth, and the location of my oral ulcer was right where my incisors press against the area behind my lips when my mouth is closed.
The oral ulcer healed after two weeks following a doctor's visit, but it has left a noticeable indentation.
The surface feels smooth when touched with my tongue.
I have previously experienced oral ulcers, and I have never encountered any indentations after healing.
I would like to know if this is a cause for concern.

Remember to be careful not to bite it again; it should grow back thicker in a while.
Wishing you safety.

Understanding oral ulcers and their healing process is crucial for maintaining oral health. Oral ulcers, also known as canker sores or aphthous ulcers, can be quite painful and may significantly affect one’s quality of life. They often arise due to various factors, including trauma, stress, nutritional deficiencies, or underlying health conditions.
In your case, it seems that the ulcer developed in a location where your teeth exert pressure on the soft tissue of your lips, which is not uncommon for individuals with dental misalignments, such as overbites. The healing process for oral ulcers typically takes about one to two weeks, but this can vary based on the ulcer's size, location, and the individual’s overall health.

The presence of a noticeable indentation or groove after the ulcer has healed is not unusual. This can occur due to the way the tissue heals. When an ulcer forms, it can cause a loss of tissue, and as the body repairs itself, the new tissue may not perfectly replicate the original structure. The smooth surface you feel with your tongue indicates that the tissue has healed, but the underlying structure may have changed, leading to the indentation.

While most oral ulcers heal without complications, it’s essential to monitor the area for any changes. If the indentation persists or if you notice any other symptoms, such as increased pain, swelling, or changes in color, it would be wise to consult a healthcare professional. They can assess whether the healing process is proceeding normally or if there are any underlying issues that need to be addressed.

In terms of treatment and management of oral ulcers, several strategies can help alleviate pain and promote healing. Over-the-counter topical treatments, such as oral gels or ointments, can provide relief by creating a protective barrier over the ulcer. Additionally, rinsing with saltwater or baking soda solutions can help reduce inflammation and promote healing. Maintaining good oral hygiene is also crucial, as it helps prevent secondary infections that can complicate the healing process.

If you find that you are experiencing recurrent ulcers or if they are particularly painful, it may be beneficial to explore potential triggers. Factors such as certain foods, stress, or nutritional deficiencies (like vitamin B12, folate, or iron) can contribute to the development of ulcers. A healthcare provider can help identify these triggers and suggest dietary or lifestyle changes to minimize their occurrence.

In summary, while the indentation left by the healed ulcer may be concerning, it is often a normal part of the healing process. However, staying vigilant and consulting with a healthcare professional if you have any concerns is always a good practice. They can provide personalized advice and treatment options to ensure your oral health remains optimal.
