Oral Lesions: What to Know About Your Mouth's Healing Process - Dentistry

Oral issues


Hello, Doctor: Previously, I accidentally bit the inside of my left cheek, causing a laceration that took about 4 to 5 days to heal.
However, after healing, I noticed a small piece of tissue growth that matches the color of my oral mucosa.
It is smooth and painless, but the sudden presence of this tissue in my mouth feels strange.
I would like to ask what type of oral condition this might be.
Thank you.

Dr. Zeng Guanghui reply Dentistry


Hello, sir: Thank you for your inquiry.
I would like to address your question and provide some advice: You have sustained an accidental bite injury to the inside of your left cheek, which has healed but left a small area that feels smooth and non-painful, yet somewhat unusual.
This may be due to mechanical irritation of the oral mucosa, leading to an inflammatory hyperplastic response.
It is advisable to consult a dentist for a thorough examination, and if necessary, an oral biopsy may be performed.
Finally, I wish you peace and happiness!

When it comes to oral lesions and the healing process of the mouth, it is essential to understand the various types of lesions that can occur, their causes, and how they heal. Based on your description, it sounds like you have experienced a common type of oral lesion known as a mucosal lesion, which can arise from trauma, such as biting the inside of your cheek.


Types of Oral Lesions
1. Traumatic Ulcers: These are often caused by accidental biting, sharp food, or dental appliances. They typically heal within a week or two, depending on the severity of the injury.

2. Fibromas: These are benign growths that can appear in the mouth, often as a result of chronic irritation or trauma. They are usually painless and can be smooth and similar in color to the surrounding tissue.

3. Aphthous Stomatitis (Canker Sores): These are painful, shallow ulcers that can occur on the soft tissues of the mouth. They are not caused by an infection and often heal on their own within one to two weeks.

4. Oral Candidiasis (Thrush): This is a fungal infection that can cause white patches in the mouth. It may require antifungal treatment.

5. Oral Cancer: While less common, persistent lesions that do not heal or change in appearance over time should be evaluated by a healthcare professional to rule out malignancy.


Healing Process
The healing process of oral lesions typically involves several stages:
1. Inflammation: After an injury, the body responds with inflammation, which helps to protect the area and initiate healing. This stage can last a few days.

2. Tissue Regeneration: New tissue begins to form as the body repairs the damaged area. This can take several days to weeks, depending on the severity of the injury.

3. Maturation: The new tissue continues to strengthen and mature over time. This stage can take weeks to months.


Your Situation
In your case, the small piece of tissue that has developed after the initial injury may be a normal part of the healing process. It could be a fibrous tissue growth (fibroma) that forms as the body repairs itself. Since you mentioned that it is smooth, the same color as the surrounding tissue, and not painful, it is likely benign. However, it is essential to monitor the lesion for any changes in size, color, or pain level.


When to Seek Medical Attention
You should consider consulting a healthcare professional if:
- The lesion persists for more than two weeks without improvement.

- You notice changes in the lesion's appearance, such as increased size, color change, or bleeding.

- You experience pain, difficulty swallowing, or any other concerning symptoms.


Conclusion
In summary, while it is common for oral lesions to develop after trauma, it is crucial to keep an eye on any changes. Maintaining good oral hygiene and avoiding further irritation to the area can help facilitate healing. If you have any concerns or if the lesion does not resolve, it is advisable to seek evaluation from a dentist or an oral specialist. They can provide a thorough examination and, if necessary, perform a biopsy to ensure that the lesion is not indicative of a more serious condition.
